TRUE

FALSE

This field is used to prevent packet forwarding loops, similar to the TTL field in an IP header.

This field is used for label management.

This field used to control the upstream device in label distribution.

This field limitation the LSR.

Common IP forwarding

ATM forwarding

Multi-label MPLS forwarding

Single-label MPLS forwarding

Provide dedicated bandwidth.

Reduce the packet loss ratio.

Prevent and manage network congestion.

Setting the source address of packets.

The DHCP client broadcasts a DHCP Discover packet. The DHCP server replies to the packet.

The DHCP client only needs to broadcast a DHCP Request packet containing the IP address obtained last time, but does not need to send a DHCP Discover packet again.

After receiving the DHCP Discover packet, the DHCP server sends a DHCP Offer packet containing the leased IP address and other settings to the DHCP client.

After receiving the DHCP Request packet, the DHCP server returns a DHCP ACK packet if the requested IP address is not allocated to another client.

Network devices, security devices, policy servers, and third-party systems can report network information and security logs.

Network information and security logs are generated by customer devices.

A switch can function as the policy execution device to respond to security events by executing security policies to restrict or block insecure access.

The United Security component of the Agile Controller is responsible for log collection, processing, event association, security trend display, and security response.

The network protocol implementation is complex, and the O&M is difficult.

The traffic path cannot be adjusted flexibly.

The upgrade of new network services is slow.

Different vendors' devices provide similar implementation, there is less difference in operation commands, and operations are easy.

TRUE

FALSE

After a static LSP is established, each node on the LSP can detect the entire LSP.

When MPLS is enabled on the outbound interface of the ingress node and the physical status and the protocol status of the outbound interface are Up, the static LSP is Up regardless of whether there is an egress node or a transit node.

The transit node of a static LSP is configured and MPLS is enabled on both the inbound and outbound interfaces. If the physical status and the protocol status of the inbound and outbound interfaces are Up, the static LSP is Up.

The egress node of the static LSP is configured and MPLS is enabled on the inbound interface. If the physical status and the protocol status of the inbound interface are Up, the static LSP is Up regardless of whether there is an ingress node or a transit node.

The first 6 bits of the ToS field (leftmost 6 bits) mark different types of services, namely, DSCP priority.

The DSCP priority can be used to classify traffic into 32 types.

Each DSCP priority corresponds to a Behavior Aggregate (BA), and a PHB can be specified for each BA.

You can use some QoS mechanisms to implement PHB.

As the ACL complexity and length increase, the firewall filtering performance deteriorates exponentially.

Static ACL rules cannot adapt to dynamic security filtering requirements.

It is easy for hackers muddle through without check the session state and analyze the data.

It can fully control network information exchange, and Session control is of high security.

LDP discovery mechanisms include the basic discovery mechanism and extended discovery mechanism.

The LDP basic discovery mechanism discovers directly-connected LDP peers on a link.

The LDP extended discovery mechanism discovers indirectly-connected LDP peers.

LDP discovery mechanisms need to specify LDP Peer.

When administrators configure Free Mobility, they need to select proper authentication points and policy execution points.

In the Free Mobility, Administrators can add static network segments or server resources to security groups, and manually bind their IP addresses to the security groups.

Free Mobility uses a configuration matrix to define access permissions between two security groups such as users and servers.

Free Mobility defines higher forwarding priorities for the VIP user group to ensure their network experience.

Preferentially guarantee the services that require short delay, low packet loss, low jitter, and assured bandwidth.

Provide channels for packet forwarding.

Ensure bandwidth for specific traffic.

Ensure that packets are forwarded with the minimum delay.

802.IX and RADIUS are different names of the same technology.

802.IX is a technological system, in which RADIUS is included.

RADIUS is a technological system, in which 802.IX is included.

802.IX and RADIUS are different technologies, but they are often used together for user access control.

Authentication domains are classified into the pre-authentication domain, isolation domain, and post-authentication domain.

A pre-authentication domain defines public network resources that users can access before passing identity authentication in the area, for example, the DNS server, external authentication source, Service Manager, and Service Controller.

An isolation domain defines resources that end users passing identity authentication but failing the security check can access. These resources such as the patch server and antivirus server can help end users eliminate violations.

A post-authentication domain defines controlled network resources that end users can access after passing identity authentication and security check, for example, the ERP system, financial system, and database.

TRUE

FALSE

By default, the DHCP service must be enabled when you configure the DHCP server and DHCP relay agent.

VLANIF 100 receives DHCP packets and forwards the packets to the external DHCP server through a relay agent.

Specify VLANIF 100 to the DHCP server group dhcpgroup1.

Create a DHCP server group first and add a DHCP server to the group.

By default, DHCP servers on the network are added to dhcpgroup1 automatically.

The total length of an MPLS label is 4 bytes (32 bits).

The TTL field in an MPLS label has the same meaning as that in an IP packet, and can prevent loops.

The S field in an MPLS label has 1 bit and is used to identify whether the label is the bottom-of-stack label. If the value is 1, the label is a penultimate-layer label.

For Ethernet and PPP packets, a label stack is located between the Layer 2 packet header and data. If a VLAN tag is available, the label stack is placed before the VLAN tag.

Reduce device and energy cost.

The Service Chain component uses a user control list (UCL) to implement access control by user level. The ACL rules are defined based on the source security group, destination security group, and port number.

An orchestration device, usually a switch, directs service flows to a service device.

A service device processes the service flows directed to it by an orchestration device. Generally, firewall, antivirus, and online behavior management devices can function as service devices.

A service chain indicates the service data passing through the GRE tunnel.
