Free and Premium HP HPE7-A02 Dumps Questions Answers

A typical use case for using HPE Aruba Networking ClearPass Onboard is to provision unmanaged devices to succeed at certificate-based 802.1X authentication. ClearPass Onboard allows users to securely configure their personal devices with the necessary certificates and network settings to authenticate on the network using 802.1X, which enhances security and simplifies the onboarding process for unmanaged devices.

1.Certificate-Based Authentication: ClearPass Onboard simplifies the process of issuing and installing certificates on unmanaged devices, ensuring they can authenticate securely using 802.1X.

2.User-Friendly Onboarding: The Onboard process is user-friendly, guiding users through the steps needed to configure their devices for network access.

3.Enhanced Security: By using certificates for authentication, the solution provides a higher level of security compared to traditional username/password methods.

RADIUS Change of Authorization (CoA):

CoA is triggered when ClearPass determines that a client’s posture status has changed (e.g., Healthy, Quarantine).

The RADIUS enforcement policy is where you configure actions and enforcement profiles that respond to these posture changes.

Option Analysis:

Option A: Correct. RADIUS enforcement policies are used to configure actions, including triggering CoA.

Option B: Incorrect. OnGuard settings configure posture agent behavior, not enforcement rules.

Option C: Incorrect. The posture policy evaluates compliance but does not trigger CoA.

Option D: Incorrect. WEBAUTH enforcement policies are for web-based authentication, not posture-related CoA.

When using "Tips

" conditions within an 802.1X service's enforcement policy, you should enable caching roles and posture attributes from previous sessions in the service's enforcement settings. This ensures that ClearPass retains posture information from previous authentications, which is necessary for making decisions based on the current posture state of an endpoint. By caching these attributes, ClearPass can apply appropriate enforcement actions based on the device's posture status.

Gateway Threat Count Alert

This alert indicates that the gateway has detected threats in traffic passing through it. HPE Aruba Networking Central provides tools to investigate and analyze these threats in detail.

Analysis of Each Option

A. Use HPE Aruba Networking Central tools to run a Network Check on the gateway with which the alert is associated:

Incorrect:

Network Check tools in Central are primarily used for connectivity and performance diagnostics, not for analyzing detected threats.

This does not provide insight into the specific threats triggering the Gateway Threat Count alert.

B. Use Live Monitoring on the gateway to download a packet capture of recent traffic flowing through the gateway:

Incorrect:

Live Monitoring and packet capture can provide raw traffic data, but interpreting this requires significant manual analysis.

The Gateway Threat Count alert already provides summarized threat insights that are easier to access via the threat list.

C. Check the threat list for the gateway associated with the alert. Access threat details and download packet info:

Correct:

The threat list is specifically designed to display detailed information about detected threats, such as their type, severity, and source/destination.

Administrators can access this list in Central for the affected gateway, view granular details, and even download associated packet data for deeper inspection.

D. Check the gateway's Audit Trail in HPE Aruba Networking Central for more details about the threats that triggered the alert:

Incorrect:

The Audit Trail tracks configuration changes and administrative actions, not the details of detected threats.

It is not relevant for investigating the Gateway Threat Count alert.

Final Recommendation

To gather more information about what caused the Gateway Threat Count alert to trigger, check the threat list for the associated gateway. This provides detailed threat information and the option to download packet data for further analysis.

Best Practices for Threat Investigation Using Aruba Central.

To configure the HPE Aruba Networking VIA solution for remote employees who need to download their VIA connection profile from the VPN Concentrator (VPNC) and ensure that only those who authenticate with their domain credentials through ClearPass Policy Manager (CPPM) can do so, you need to set up a VIA Authentication Profile. This profile should use the CPPM's RADIUS server group. Once the VIA Authentication Profile is created, you need to reference this profile in the VIA Web Authentication Profile. This configuration ensures that the authentication process requires employees to validate their credentials via CPPM before they can download the VIA connection profile.

When HPE Aruba Networking Central detects an Infrastructure Attack, such as "Detect adhoc using Valid SSID," the next step is to locate the general area of the threat. You can use HPE Aruba Networking Central floorplans or the identities of the detecting APs to pinpoint the approximate location of the adhoc network. This allows you to physically investigate and address the source of the threat, ensuring that unauthorized or rogue networks are quickly identified and mitigated.

Centralized Role Configuration on CPPM:

CPPM can assign roles to clients dynamically during authentication.

However, the actual ACL policies (e.g., firewall policies) must already exist and be referenced locally on the switch.

CPPM cannot directly configure ACL details on AOS-CX switches.

Option Analysis:

Option A: Correct. The role is defined on CPPM, but it references a policy pre-configured on the switch.

Option B: Incorrect. This does not align with Aruba's centralized role-based access control design.

Option C: Incorrect. CPPM cannot configure the ACL policies and classes directly; they must exist locally.

Option D: Incorrect. Policies can be referenced centrally but not fully configured on CPPM.

When using OpenSSL to obtain a certificate signed by a Certification Authority (CA), you should submit the Certificate Signing Request (CSR) file, which is file1.pem, to the CA. The CSR contains the information about the entity requesting the certificate and the public key, but not the private key, which is in file2.pem. The CA uses the information in the CSR to create and sign the certificate.

1.CSR Submission: The CSR (file1.pem) includes the public key and the entity information required by the CA to issue a certificate.

2.Private Key Security: The private key (file2.pem) should never be sent to the CA or shared; it remains securely stored on the requestor’s server.

3.Certificate Issuance: After the CA signs the CSR, the resulting certificate can be used with the private key to establish secure communications.

To tunnel VoIP phone traffic from AOS-CX switches to an HPE Aruba Networking gateway, you need to configure a User-Based Tunneling (UBT) reserved VLAN on the switches. This VLAN is dedicated for tunneling purposes and ensures that the VoIP traffic is correctly identified and tunneled to the gateway where security policies can be applied.

1.UBT Configuration: Setting a UBT reserved VLAN ensures that the switch knows which VLAN to use for tunneling traffic to the gateway.

2.Traffic Tunneling: The reserved VLAN helps in segregating the VoIP traffic, ensuring it is handled securely and according to the configured policies at the gateway.

3.Policy Application: By tunneling the traffic, the gateway can apply advanced security policies to the VoIP traffic.

Internet Key Exchange (IKE)/IKEv2 plays a crucial role in an HPE Aruba Networking client-to-site VPN by helping to negotiate the IPsec Security Association (SA) automatically and securely. IKE/IKEv2 handles the authentication and key exchange processes, ensuring that both the client and the VPN gateway can establish a secure IPsec tunnel.

1.SA Negotiation: IKE/IKEv2 automates the negotiation of the Security Association, which defines the parameters for the secure IPsec tunnel.

2.Secure Authentication: It provides a secure method for authenticating the communicating parties and exchanging cryptographic keys.

3.Efficiency: Using IKE/IKEv2 simplifies the setup and maintenance of secure VPN connections, enhancing the overall security and reliability of the VPN.

To follow best security practices for 802.1X authentication settings in Windows domain clients:

Specify at least two server names under "Connect to these servers":

Admins should explicitly list trusted RADIUS server names (e.g., radius.example.com) to prevent the client from connecting to unauthorized or rogue servers.

This mitigates man-in-the-middle (MITM) attacks where an attacker attempts to present their own RADIUS server.

Select the desired Trusted Root Certificate Authority and "Don't prompt users":

Select the Trusted Root CA that issued the RADIUS server's certificate. This ensures clients validate the correct server certificate during the EAP-TLS/PEAP authentication process.

Enabling "Don't prompt users" ensures end users are not confused or tricked into accepting certificates from untrusted servers.

Why the other options are incorrect:

Option C: Incorrect. Wildcards in server names (e.g., *.example.com) weaken security and allow broader matching, increasing the risk of rogue servers.

Option D: Incorrect. Clearing "Use simple certificate selection" requires users to select certificates manually, which can lead to errors and usability issues. Simple certificate selection is recommended when properly configured.

Recommended Settings for Best Security Practices:

Server Validation: Specify the exact RADIUS server names in the "Connect to these servers" field.

Root CA Validation: Ensure only the correct Trusted Root Certificate Authority is selected.

User Prompts: Enable "Don't prompt users" to enforce automatic and secure authentication without user intervention.

Syslog Integration with CPPM:

ClearPass Policy Manager (CPPM) can integrate with third-party firewalls via Syslog messages to detect and respond to internal threats.

The Syslog integration enables CPPM to gather context on suspicious activity and enforce appropriate policies such as isolating attackers by working with network devices like Aruba switches and APs.

Option A: Correct. This method allows for dynamic response to threats and leverages existing infrastructure without requiring major reconfiguration.

Option B: Incorrect. CPDI is primarily used for profiling devices, not directly for threat response based on Syslog information.

Option C: Incorrect. While it is possible for CPPM to poll information, this approach is less dynamic and not focused on immediate threat response.

Option D: Incorrect. Tunnel mode SSIDs and UBT are designed for forwarding user traffic securely but do not directly enhance threat detection or mitigation.

Comprehensive Detailed Explanation

Traffic Match Evaluation Order:

The rules are processed in sequential order, and the first rule that matches is applied.

The added rule only denies SSH traffic to 10.1.4.0/23. Since 10.1.11.42 is not within the 10.1.4.0/23 subnet, this rule does not apply.

Next Matching Rule:

Rule 2 permits traffic to the 10.1.6.0/23 network, but this does not include 10.1.11.42.

Rule 3 denies traffic to the broader 10.1.0.0/16 network and logs it. Since 10.1.11.42 falls under this range, this rule applies, and the traffic would be logged and dropped.

Logging and Denylist Actions:

The denylist action in the new rule only applies to SSH traffic to 10.1.4.0/23. Since the destination is outside that range, the denylist is not triggered.

HPE Aruba Central Configuration Best Practices Guide.

One use case that companies can fulfill using HPE Aruba Networking ClearPass Policy Manager's (CPPM's) Device Profiler is leveraging artificial intelligence to more accurately identify Internet of Things (IoT) devices. ClearPass Device Profiler uses AI and machine learning to analyze network traffic and device behavior, providing detailed and accurate identification of IoT devices on the network. This helps in managing and securing diverse and numerous IoT devices by ensuring they are correctly profiled and assigned appropriate access policies.

RAPIDS Ad-Hoc Detection:

The alert "Detect ad-hoc using Valid SSID" indicates that a device is broadcasting an SSID that matches a valid network SSID in ad-hoc mode. This can be an indication of an infrastructure attack or misconfiguration.

Next Steps:

Use Aruba Central floorplans or AP location data to identify the physical area where the offending device is detected.

Locate and investigate the device to determine if it is malicious or simply misconfigured.

Option Analysis:

Option A: Incorrect. While tuning thresholds is useful for reducing false positives, this step does not directly address a potential threat.

Option B: Incorrect. Faulty drivers can cause similar behavior, but this step is not immediately actionable without locating the device first.

Option C: Correct. Floorplans or AP identities help locate the threat's physical area for further investigation.

Option D: Incorrect. RAPIDS focuses on detecting devices via SSID and MAC, not IP addresses, making this approach less relevant.

Hub-Spoke VPN Configuration:

HPE Aruba Central SD-WAN Orchestrator enables hub-spoke topology where branch gateways (BGWs) connect to VPN concentrators (VPNCs) located at data centers.

A key step in configuring this is defining which VPNCs the BGWs will prefer for connectivity.

The DC Preference List is configured in the BGW groups to prioritize the data centers to which BGWs connect.

Option Analysis:

Option A: Incorrect. VPN pools control IP allocation, not which branches connect to VPNCs.

Option B: Incorrect. IKE policies define key exchange mechanisms but are not part of the connection preference process.

Option C: Correct. Admins configure a DC preference list in BGW groups to determine connectivity priorities with VPNCs.

Option D: Incorrect. IPsec policies define encryption parameters at a global level, but this is not specific to the hub-spoke connection configuration.

Comprehensive Detailed Explanation

The requirement is to permit HTTPS traffic from clients to the 10.2.12.0/24 subnet.

ZoneC is configured to drop all HTTPS traffic to the 10.2.0.0/16 subnet. Therefore, the first match in the zoneC class (priority 10) will drop the desired traffic.

To override this behavior, you must add a higher-priority rule (lower rule number) to zoneC that explicitly matches 10.2.12.0/24 and permits the traffic.

Thus, adding the rule 5 match any 10.2.12.0/24 eq https to zoneC ensures the desired traffic is permitted while maintaining the drop behavior for the rest of 10.2.0.0/16.

AOS-CX Role-Based Access Control documentation.

Understanding class priority and policy rule ordering in AOS-CX.

For a company that wants to apply a standard configuration to all AOS-CX switch ports and dynamically adjust their configuration based on the identity of the user or device that connects, the best approach is to have the switches download user-roles from HPE Aruba Networking ClearPass Policy Manager (CPPM). This method centralizes the configuration of identity-based settings in CPPM, allowing it to dynamically assign roles and policies to switch ports based on authentication and authorization results. This ensures consistent and secure network access control tailored to each user or device.

Packet Capture in Aruba Central:

Aruba Central provides tools for remote packet captures directly from the APs.

On the "Security" page for the AP, you can initiate a packet capture session, specifying the client device and capture duration.

The traffic is captured into a PCAP file, which can be downloaded and analyzed using tools like Wireshark.

Option Analysis:

Option A: Incorrect. While possible via CLI, Aruba Central provides a simpler method for packet captures.

Option B: Correct. Aruba Central’s "Security" page allows you to capture and export client traffic efficiently.

Option C: Incorrect. The "Live Events" page focuses on monitoring events, not packet captures.

Option D: Incorrect. Port mirroring on the switch captures AP traffic but requires more manual configuration and does not isolate client-specific wireless traffic easily.

Policy Analysis:

Rule Evaluation Order: Rules are applied in sequential order until a match is found.

Key Points:

DHCP traffic (UDP 67) is permitted.

DNS traffic (UDP 53) is permitted.

Traffic to 10.5.5.0/24 is explicitly denied.

HTTP traffic (TCP 80) is allowed only to 10.5.0.0/16.

HTTPS traffic (TCP 443) is allowed only to 10.5.0.0/16.

All other traffic to 10.5.0.0/16 is denied.

Any other traffic not matching the above rules is permitted.

Scenario Analysis:

The client IP 10.2.2.2 does not fall within the 10.5.0.0/16 subnet.

Rule 3 denies traffic to 10.5.5.5, regardless of the source IP.

Option A: Correct. HTTPS traffic to 10.5.5.5 is explicitly denied by Rule 3.

Option B: Incorrect. Traffic to 203.0.113.12 is permitted due to the final "permit any" rule.

Option C: Incorrect. The client (10.2.2.2) does not belong to the subnet 10.5.0.0/16, so traffic to 10.5.3.3 is not permitted by Rule 5.

Option D: Incorrect. HTTP traffic to 198.51.100.12 is allowed by the last "permit any" rule.

In the exhibit, the HPE Aruba Networking Central settings for the 9x00 gateway show that traffic inspection is enabled, and the gateway is set to operate in IDS (Intrusion Detection System) mode with the fail strategy set to "Block". This configuration means that the gateway will drop traffic if it matches a rule in the active ruleset.

1.Active Ruleset: The ruleset version 9861 is active, and the gateway is configured to automatically update the ruleset daily.

2.Traffic Matching Rules: When traffic matches a rule in the active ruleset, it is flagged as suspicious or malicious.

3.Block Mode: Since the fail strategy is set to "Block", any traffic that matches a rule in the active ruleset will be dropped to prevent potential threats.

When an AOS-CX switch implements User-Based Tunneling (UBT) to a cluster of three HPE Aruba Networking gateways, the switch determines to which gateway to tunnel each user's traffic based on the particular gateway assigned as that user's active user designated gateway. This ensures that traffic is efficiently distributed and managed according to the designated gateway for each user.

1.User Designated Gateway: Each user's traffic is tunneled to a specific gateway that has been designated for that user, ensuring efficient handling of traffic.

2.Traffic Distribution: This method allows for balanced distribution of user traffic across multiple gateways, enhancing network performance and reliability.

3.Gateway Assignment: The switch uses the assigned gateway for each user to determine the tunneling path, ensuring that traffic is directed to the appropriate gateway.

If VIA clients are not receiving IP addresses from the configured VPN pool, one setting to check is whether the pool is associated with the role to which the VIA clients are being assigned. The association between the IP pool and the role ensures that clients assigned to that role receive IP addresses from the correct pool.

1.Role Association: Each role can be associated with a specific IP pool, ensuring that clients assigned to the role receive addresses from the intended pool.

2.IP Allocation: Proper configuration of the IP pool and its association with the role is crucial for correct IP address allocation.

3.VIA Configuration: Ensuring that all settings, including IP pool associations, are correctly configured, facilitates seamless client connectivity.

HPE Aruba Central Live Monitoring:

Aruba Central provides real-time Live Monitoring of network devices, including:

Application usage statistics.

Trends and changes over time for specific devices.

This information is presented in a clear and easy-to-read format, making it ideal for examining changes in application usage over different time ranges.

Option Analysis:

Option A: Incorrect. ClearPass OnGuard monitors endpoint compliance (e.g., antivirus, OS version) but does not analyze application usage.

Option B: Correct. Aruba Central's Live Monitoring page is specifically designed for this type of analysis.

Option C: Incorrect. ClearPass Insight generates endpoint security reports but does not track application usage.

Option D: Incorrect. ClearPass Device Insight (CPDI) focuses on device profiling and identification, not continuous application monitoring.

When setting up a ClearPass cluster, it is critical to ensure secure communication between the cluster nodes and the client devices. For this purpose, certain certificates must be properly configured.

1. Why HTTPS Requires a CA-Signed Certificate?

HTTPS communication is used for inter-cluster communication and for the web-based user interface that administrators use to manage the ClearPass cluster.

Before joining the cluster, it is strongly recommended to install a CA-signed HTTPS certificate on the Subscriber to ensure secure communication and prevent warnings/errors due to untrusted certificates.

Without a CA-signed certificate, the Subscriber might use a self-signed certificate, leading to security risks and lack of trust validation.

2. Analysis of Other Certificate Types

B. Database:

Incorrect: Database communications within ClearPass clusters are secured using internal certificates or keys. These are not user-facing and do not require a CA-signed certificate before joining the cluster.

C. RADIUS/EAP:

Incorrect: RADIUS/EAP certificates are important for client authentication, but they are not required on the Subscriber prior to cluster joining. These can be configured after the Subscriber is part of the cluster.

D. RadSec:

Incorrect: RadSec is an optional feature for secure RADIUS communication over TLS, and its certificate configuration is typically performed post-cluster setup.

Final Recommendation

To ensure secure cluster operations and seamless web-based management, a CA-signed HTTPS certificate should be installed on the Subscriber before it joins the ClearPass cluster.

When enabling Wireless IDS/IPS infrastructure and client detection at a high level on HPE Aruba Networking APs without enabling prevention settings, HPE Aruba Networking recommends configuring detection at a custom level and adjusting settings to minimize false positives. This approach allows for effective monitoring while reducing the risk of unnecessary alerts and maintaining the accuracy of detections.

1.Custom Level Configuration: By customizing the detection settings, you can tailor the system to your specific environment, ensuring that only relevant threats are detected and reducing false positives.

2.False Positive Reduction: Disabling or tuning settings that are likely to produce false positives helps in maintaining the reliability of the detection system and prevents alert fatigue.

3.Focused Detection: Custom configuration ensures that the IDS/IPS focuses on critical detections, improving overall security posture.

To prevent rogue OSPF routers in the network shown in the exhibit, the preferred configuration on Switch-2 is to configure OSPF authentication on Lag 1 in MD5 mode. This setup enhances security by ensuring that only routers with the correct MD5 authentication credentials can participate in the OSPF routing process. This method protects the OSPF sessions against unauthorized devices that might attempt to introduce rogue routing information into the network.

1.OSPF Authentication: Implementing MD5 authentication on Lag 1 ensures that OSPF updates are secured with a cryptographic hash. This prevents unauthorized OSPF routers from establishing peering sessions and injecting potentially malicious routing information.

2.Secure Communication: MD5 authentication provides a higher level of security compared to simple password authentication, as it uses a more robust hashing algorithm.

3.Applicability: Lag 1 is the primary link between Switch-1 and Switch-2, and securing this link helps protect the integrity of the OSPF routing domain.

The Network Analytics Engine (NAE) in AOS-CX switches provides intelligent monitoring, troubleshooting, and performance analysis through predefined or custom scripts. Here’s an analysis of the guidelines for NAE:

A. Each switch model has a maximum number of supported monitors, and one agent might have multiple monitors.

Correct:

Each AOS-CX switch model has hardware and software limitations, including the number of agents and monitors it supports.

Monitors are data collection points for tracking specific metrics like interface statistics, CPU usage, or custom-defined parameters.

Agents are scripts that use monitors to evaluate data, trigger actions, or generate alerts.

Since one agent can have multiple monitors, the total number of monitors might impact the scalability of agents.

B. You can install multiple scripts on a switch, but you can deploy only one agent per script.

Incorrect:

Multiple agents can be deployed from the same script if they monitor different parameters or have different configurations.

The limitation is usually related to the total number of agents and monitors supported by the switch model, not the script itself.

C. The switch will permit you to deploy as many NAE agents as you want, but they might degrade the switch functionality.

Incorrect:

AOS-CX enforces hardware and software limits on the number of agents and monitors. These limits are designed to prevent degradation of switch performance.

You cannot deploy an unlimited number of agents, as the system enforces these restrictions.

D. When you use custom scripts, you can create as many agents from each script as you want.

Incorrect:

While you can use custom scripts to create agents, the total number of agents is subject to the switch's maximum supported limits.

The scalability of agents is still bound by hardware and software constraints, even with custom scripts.

Best Practices for NAE Deployment in AOS-CX Networks.

User-Based Tunneling (UBT) with VRRP:

UBT allows traffic from authenticated users to be tunneled to an HPE Aruba Networking gateway.

In the case of VRRP, where two gateways are configured for redundancy, the AOS-CX switch will always send the traffic to the primary gateway defined in the UBT zone configuration.

The VRRP state (master/backup) does not impact the UBT decision; the UBT primary configuration takes precedence.

Option Analysis:

Option A: Incorrect. UBT does not strictly follow the VRRP master; it adheres to the UBT primary gateway configuration.

Option B: Correct. The switch tunnels all traffic to the primary gateway configured in the UBT zone.

Option C: Incorrect. UBT does not load-share traffic between gateways.

Option D: Incorrect. UBT uses the primary gateway configured in the UBT zone, not dynamically determined active devices.

802.1X Authentication Modes:

Client Auth-Mode: Requires each connected endpoint to authenticate individually using 802.1X.

Device Auth-Mode: Allows the port to authenticate a device, such as an AP, as a whole. This mode works when the device bridges traffic (e.g., AP bridging SSID traffic).

AP Role Configuration:

Since the AP bridges traffic from multiple clients, you must configure the AP role to use device auth-mode.

Meanwhile, the ports on edge switches can remain in client auth-mode to enforce 802.1X for individual client connections.

Option Analysis:

Option A: Correct. This ensures the AP itself authenticates with device auth-mode, while edge ports remain in client auth-mode.

Option B: Incorrect. APs require device auth-mode for bridging, not client auth-mode.

Option C: Incorrect. Device auth-mode on all ports would not meet the security policy for clients.

Option D: Incorrect. Leaving all ports in device auth-mode does not meet the policy for 802.1X on edge ports.

To support 802.1X authentication and download user roles from HPE Aruba Networking ClearPass Policy Manager (CPPM) on AOS-CX switches, you must install the root CA certificate for CPPM's RADIUS certificate in a Trust Anchor (TA) profile on the switches. This ensures that the switches trust the RADIUS server certificate presented by CPPM during the authentication process.

1.Root CA Certificate: Installing the root CA certificate ensures that the switch can verify the authenticity of the RADIUS server certificate provided by CPPM.

2.Trust Anchor Profile: The TA profile on the switch holds the root CA certificate, establishing a trust relationship between the switch and the CPPM RADIUS server.

3.Secure Authentication: This setup is essential for securing the 802.1X authentication process and enabling the download of user roles.

To ensure that HPE Aruba Networking ClearPass Policy Manager (CPPM) responds correctly to Syslog messages from a Check Point firewall, you need to check that the Ingress Event Dictionaries for Check Point messages are enabled. These dictionaries are necessary for CPPM to properly interpret and respond to the Syslog messages received from the firewall.

1.Event Dictionaries: Ingress Event Dictionaries allow CPPM to understand the specific format and content of Syslog messages from various sources, such as Check Point firewalls.

2.Message Interpretation: Without these dictionaries enabled, CPPM may not correctly interpret the Syslog messages, leading to a failure in triggering the expected actions.

3.Configuration Check: Ensuring that the dictionaries are enabled is crucial for the proper functioning of the event service and accurate response to security events.

To set up HPE Aruba Networking ClearPass Policy Manager (CPPM) to enforce certificate-based authentication for clients using Tunneled EAP (TEAP), you need to select an EAP-TLS-type authentication method for TEAP's inner method. TEAP allows for a combination of certificate-based (EAP-TLS) and password-based (EAP-MSCHAPv2) authentication. By choosing EAP-TLS as the inner method, you ensure that the clients are authenticated using their certificates, thus enforcing certificate-based authentication within the TEAP framework.

Traffic Forwarding for APs:

In AOS-10, AP traffic forwarding can happen locally (bridged) or through tunnels to a gateway.

The VLAN settings on the "APs" role depend on whether the APs bridge the SSID traffic locally or forward it through a tunnel.

Option B: Correct. You need to know whether the traffic is bridged or tunneled to determine the VLAN assignments.

Option A: Incorrect. LURs/DURs affect role assignment but not VLAN settings for traffic forwarding.

Option C: Incorrect. Establishing tunnels with gateways is relevant to centralized traffic forwarding, not VLANs for bridged traffic.

Option D: Incorrect. AP IP addressing (static or DHCP) does not impact the VLAN for forwarded SSID traffic.

When establishing a cluster of HPE Aruba Networking ClearPass servers, it is recommended to install a CA-signed certificate for HTTPS on the Subscriber before it joins the cluster. This ensures secure communication between the servers in the cluster and provides a trusted certificate for client connections.

1.HTTPS Security: A CA-signed certificate for HTTPS ensures that all web-based communication to and from the ClearPass server is encrypted and secure.

2.Cluster Communication: Secure communication between ClearPass nodes in the cluster is essential for synchronization and data integrity.

3.Client Trust: Clients accessing the ClearPass server will trust the CA-signed certificate, avoiding security warnings and ensuring smooth operations.

When you have created a rule in a ClearPass Policy Manager (CPPM) service's enforcement policy to quarantine devices with endpoint conflicts, it is important to consider whether the company has devices that use PXE boot. PXE booting devices can create conflicts in the profiler because they may temporarily have different network attributes (e.g., MAC address or IP address) before fully booting and obtaining their final configuration. Understanding whether PXE boot is in use can help determine if profiler parameters need to be adjusted to ignore such temporary conflicts, ensuring that devices are not incorrectly quarantined.

To enforce 802.1X authentication for Windows domain computers to HPE Aruba Networking ClearPass Policy Manager (CPPM) and have the computers authenticate as both machines and users in the same session, you should set up TEAP (Tunneled EAP) as the authentication method. TEAP supports both machine and user authentication within a single 802.1X session, making it suitable for scenarios where both types of authentication are required simultaneously.

Voice Role VLAN Configuration:

When VoIP phones are authenticated and assigned to the "voice" role, VLAN 12 should be explicitly defined as an allowed trunk VLAN within the role configuration.

The VLAN configuration should be role-specific rather than on the edge port, as this ensures dynamic VLAN assignment based on authentication results.

Option Analysis:

Option A: Incorrect. Native VLANs are for untagged traffic, but VoIP traffic is tagged.

Option B: Correct. VLAN 12 must be configured as the allowed trunk VLAN in the "voice" role to tag VoIP traffic correctly.

Option C: Incorrect. Configuring VLAN 12 in both edge port and role settings is redundant and unnecessary.

Option D: Incorrect. Native VLANs do not handle tagged traffic like VLAN 12 for VoIP phones.

ClearPass Role Mapping Policy:

The Endpoint namespace is used to reference attributes and tags related to endpoint devices.

Device Insight Tags are part of endpoint profiling information and are stored in the Endpoint Repository.

Option Analysis:

Option A: Correct. The Endpoint namespace includes Device Insight Tags.

Option B: Incorrect. TIPS refers to system attributes and configuration data, not endpoint tags.

Option C: Incorrect. Device is not a valid namespace in this context.

Option D: Incorrect. Application relates to application-level attributes, not Device Insight Tags.
