• Question 292:

  Which of the following statements are correct regarding priority in VRRP?

  A. The IP address owner always uses 255 as its priority regardless its config priority.
  B. The IP address owner always uses 0 as its priority regardless its config priority.
  C. We can configure the priority as 0 to make the router never attend the Master election.
  D. If a VRRP router changes from Master to Slave, it will send out a VRRP message with priority 0 in the network.
  A. The IP address owner always uses 255 as its priority regardless its config priority.

• Question 293:

  Assume that the WRED policy for packets with the priority of AF21 is thaA. the length of the queue for saving packets ranges from 35 to 40, and the discarding percentage is 50%.When a packet with the priority being AF21 arrives, which of the following statements are true? (Select 3 Answers)

  A. If the average length of the queue is smaller than 35, the packet is added to the queue.
  B. If the length of the queue ranges between 35 and 40, the packet may be discarded with a possibility of 50%.
  C. If the average length of the queue is greater than 40, the packet is added to the queue.
  D. If the average length of the queue is greater than 40, the packet is discarded.
  A. If the average length of the queue is smaller than 35, the packet is added to the queue.
  B. If the length of the queue ranges between 35 and 40, the packet may be discarded with a possibility of 50%.
  D. If the average length of the queue is greater than 40, the packet is discarded.

• Question 294:

  Which of the following statements about traffic policing are true? (Select 3 Answers)

  A. Is used to limit the traffic transmission rate.
  B. Is used to color packets.
  C. Caches packets whose transmission rate exceeds the limit.
  D. Re-marks packets with priorities.
  A. Is used to limit the traffic transmission rate.
  B. Is used to color packets.
  D. Re-marks packets with priorities.

• Question 295:

  Assume that the following commands are run to configure BGP:

  timerkeepalive 30 hold 90

  peer 1.1.1.2 timer keepalive 10 hold 30

  Which statements about the configurations are true? (Select 2 Answers)

  A. The global configuration is preferred. Therefore, the timer values for peer 1.1.1.2 are "keepalive 30 hold 90."
  B. The peer configuration is preferred. Therefore, the timer values for peer 1.1.1.2 are "keepalive 10 hold 30."
  C. The smaller one between the global and peer timer values is used. Therefore, the timer values of peer 1.1.1.2 is "keepalive 10 hold 30".
  D. The default configuration is "timer keepalive 60 hold 180." Therefore, peer 1.1.1.2 can detect connection faults faster than the default configuration.
  B. The peer configuration is preferred. Therefore, the timer values for peer 1.1.1.2 are "keepalive 10 hold 30."
  D. The default configuration is "timer keepalive 60 hold 180." Therefore, peer 1.1.1.2 can detect connection faults faster than the default configuration.

• Question 296:

  Which of the following statements is false?

  A. The metric of a Type-1 external route is the sum of the AS internal metric (metric to reach an ASBR) and the AS external metric (metric from the ASBR to the destination network).
  B. The metric of a Type-2 external route is only the AS external metric.
  C. The metric of an external route is the sum of the AS external metric and the AS internal metric.
  D. The prerequisite for setting Forwarding Address to a non-zero value is that the next hop of the external route imported into OSPF is within the OSPF routing area.
  C. The metric of an external route is the sum of the AS external metric and the AS internal metric.

• Question 297:

  The core of the MPLS technology is label switching.

  A. True
  B. False
  A. True

• Question 298:

  In OSPF, the process of calculating shortest path tree can be divided into two phases, calculate Transit node first, then calculate Stub network.

  A. True
  B. False
  A. True

• Question 299:

  In transit AS, why do core routers run BGP?

  A. Eliminate route loops
  B. Ensure data packets can be transmitted to the external destination addresses
  C. Optimize network within an AS
  D. Ensure only one export
  B. Ensure data packets can be transmitted to the external destination addresses

• Question 300:

  Which statements about BGP route selection rules are true? (Select 3 Answers)

  A. BGP first ignores routes with unreachable next hops.
  B. A summarized route takes precedence over a non-summarized route.
  C. IBGP routes take precedence over EBGP routes.
  D. If other conditions of routes are the same, the route with the shortest Cluster_List is preferred.
  A. BGP first ignores routes with unreachable next hops.
  B. A summarized route takes precedence over a non-summarized route.
  D. If other conditions of routes are the same, the route with the shortest Cluster_List is preferred.
