PSE-Strata-Pro-24 Exam Dumps : Palo Alto Networks Systems Engineer Professional - Hardware Firewall

Palo Alto Networks' PAN-OS supports API keys for authentication when interacting with the firewall’s RESTful and XML-based APIs. By default, API keys do not have an expiration time set, but the expiration time for API keys can be configured by an administrator to meet specific requirements, such as a time-based deactivation after two hours. This is particularly useful for compliance and security purposes, where API keys should not remain active indefinitely.

Here’s an evaluation of the options:

Option A:This is incorrect because the default setting for API keys does not include an expiration time. By default, API keys are valid indefinitely unless explicitly configured otherwise.

Option B:This is incorrect because PAN-OS fully supports API keys. The API keys are integral to managing access to the firewall's APIs and provide a secure method for authentication.

Option C:This is incorrect because PAN-OS does support API key expiration when explicitly configured. While the default is "no expiration," the feature to configure an expiration time (e.g., 2 hours) is available.

Option D (Correct):The correct response to the RFP clause is that the default API key settings need to be modified to set the expiration time to 120 minutes (2 hours). This aligns with the customer requirement to enforce API key deactivation based on time. Administrators can configure this using the PAN-OS management interface or the CLI.

How to Configure API Key Expiration (Steps):

Access theWeb InterfaceorCLIon the firewall.

Navigate toDevice > Management > API Key Lifetime Settings(on the GUI).

Set the desired expiration time (e.g., 120 minutes).

Alternatively, use the CLI to configure the API key expiration:

set deviceconfig system api-key-expiry

commit

Verify the configuration using the show command or by testing API calls to ensure the key expires after the set duration.

The appropriate CDSS subscription to inspect and mitigate suspicious DNS traffic isAdvanced DNS Security. Here’s why:

Advanced DNS Securityprotects against DNS-based threats, including domain generation algorithms (DGA), DNS tunneling (often used for data exfiltration), and malicious domains used in attacks. It leverages machine learning to detect and block DNS traffic associated with command-and-control servers or other malicious activities. In this case, unusually high DNS traffic to an unfamiliar IP address is likely indicative of a DNS-based attack or malware activity, making this the most suitable service.

Option A:Advanced Threat Prevention (ATP) focuses on identifying and blocking sophisticated threats in network traffic, such as exploits and evasive malware. While it complements DNS Security, it does not specialize in analyzing DNS-specific traffic patterns.

Option B:Advanced WildFire focuses on detecting and preventing file-based threats, such as malware delivered via email attachments or web downloads. It does not provide specific protection for DNS-related anomalies.

Option C:Advanced URL Filtering is designed to prevent access to malicious or inappropriate websites based on their URLs. While DNS may be indirectly involved in resolving malicious websites, this service does not directly inspect DNS traffic patterns for threats.

Option D (Correct):Advanced DNS Security specifically addresses DNS-based threats. By enabling this service, the customer can detect and block DNS queries to malicious domains and investigate anomalous DNS behavior like the high traffic observed in this scenario.

How to Enable Advanced DNS Security:

Ensure the firewall has a valid Advanced DNS Security license.

Navigate toObjects > Security Profiles > Anti-Spyware.

Enable DNS Security under the "DNS Signatures" section.

Apply the Anti-Spyware profile to the relevant Security Policy to enforce DNS Security.

Best Practices for DNS Security Configuration.

Segregating a network into unique BGP environments requires the ability to configure separateeBGP autonomous systems(AS) within the NGFW. Palo Alto Networks firewalls support advanced BGP features, including the ability to create and manage multiple autonomous systems.

Why "It can be addressed by creating multiple eBGP autonomous systems" (Correct Answer B)?PAN-OS supports the configuration of multiple eBGP AS environments. By creating unique eBGP AS numbers for different parts of the network, traffic can be segregated and routed separately. This feature is commonly used in multi-tenant environments or networks requiring logical separation for administrative or policy reasons.

Each eBGP AS can maintain its own routing policies, neighbors, and traffic segmentation.

This approach allows the NGFW to address the customer’s need for segregated internal BGP environments.

Why not "It cannot be addressed because PAN-OS does not support it" (Option A)?This statement is incorrect because PAN-OS fully supports BGP, including eBGP, iBGP, and features like route reflectors, confederations, and autonomous systems.

Why not "It can be addressed with BGP confederations" (Option C)?While BGP confederations can logically group AS numbers within a single AS, they are generally used to simplify iBGP designs in very large-scale networks. They are not commonly used for segregating internal environments and are not required for the described use case.

Why not "It cannot be addressed because BGP must be fully meshed internally to work" (Option D)?Full mesh iBGP is only required in environments without route reflectors. The described scenario does not mention the need for iBGP full mesh; instead, it focuses on segregated environments, which can be achieved with eBGP.
