19. Which of the following statements regarding VRRP fast switchover are false? (Multiple Choice)

When association between VRRP and the BFD or EEM session is enabled and the BFD or EEM session status changes, the change is notified to the VRRP module, implementing VRRP fast switchover.

A VRRP group cannot monitor the peer BFD session, link BFD session, and normal BFD session simultaneously.

When the VRRP group is associated with a normal BFD session and the BFD session status changes, the priority of the VRRP group is changed to trigger the switchover. When the status of the monitored BFD session recovers, the priority of the router in the VRRP group is restored.

If VRRP is configured to monitor multiple BFD sessions, the associations may affect services.

23. Which of the following statements regarding AS_Path is false?

AS_Path is a list of ASs that a BGP route passes through.

AS_Path is a very important well-known mandatory attribute in BG

BGP does not accept the routes whose AS_Path attribute contains the local AS number.

When a router has two or more routes to the same destination, the router compares the AS_Path attributes of these routes and prefers the route with the longer AS_Path attribute.

25. On a carrier’s MPLS VPN network, PE1 and PE2 transmit data packets between VPNs.

After the packet arrives at PE2, PE2 distributes label 1025 to the packet.

When a client on PE2 accesses this route, what are the outer and inner labels in the packet transmitted over the carrier network?

Outer label: 1027; inner label: 1025

38. Which of the following statements regarding route selection tools is false?

An access control list (ACL) matches routing information or addresses in data packets to filter out routes or data packets that do not meet matching conditions.

An IP prefix matches destination addresses of routes or directly applies to a router object (gateway).

An AS-Path filter matches the AS-Path attribute in BGP mutes, so it can only filter BGP mutes.

A community-filter matches community attributes in BGP routes, so it can only filter BGP mutes.

A route-policy can only match mutes and data packets, but cannot change route attributes or forwarding behaviors for data packets.

39. Which of the following statements regarding the STP configuration is true?

STP automatically runs by default and therefore does not require configuration.

The STP convergence speed is slow, which may cause network interruption. Therefore, disabling STP is a preferred solution.

Similar to the implementation of routing protocols, data flows between switches can be adjusted by modifying link costs.

For routine STP configuration, the position of the STP blocked port is controlled to ensure that the blocked port is not located on a backbone link or device.

The RSTP algorithm is simple and reliable and supports fast convergence. Therefore, all switches on the network are configured to work in RSTP mode.

traffic-policy p1 inbound

traffic classifier p1 inbound

traffic behavior p1 inbound
