  A. 300
  B. 500
  C. 400
  D. 5

• Question 275:

  Since BGP is an EGP routing protocol, BGP routing policies can only be deployed between EBGP neighbors. The routing policy deployed between IBGP neighbors is invalid.

  A. True
  B. False
  B. False

• Question 276:

  On the network shown in the figure, IS-IS runs on R1, R2, R4, and R5, and the area ID is 49.0001. IS-IS runs on R3 and R6, and the area ID is 49.0002. In AS 65000, R1, R3, R4, and R6 each establish iBGP peer relationships with R2 and R5. R2 and R5 are RRs (Route Reflectors), and R1, R4, R3, and R6 are clients. The iBGP peer relationships are established using Loopback0 on each router, and the router ID is 10.0.0.X/32, where X is the number of the router. R1 and R4 import the external route 192.168.1.0/24 to BGP through the import-route command, and R3 and R6 import the external route 192.168.2.0/24 to BGP through the import-route command. Which of the following statements are true?

  

  A. The routing table of R4 contains two equal-cost default routes.
  B. The route 192.168.1.0/24 in the routing table of R3 has two next hops.
  C. The routing table of R1 does not contain the route 192.168.2.0/24.
  D. For 192.168.1.0/24, R3 preferentially selects the BGP route received from R2, and R6 preferentially selects the BGP route received from R5.
  B. The route 192.168.1.0/24 in the routing table of R3 has two next hops.
  D. For 192.168.1.0/24, R3 preferentially selects the BGP route received from R2, and R6 preferentially selects the BGP route received from R5.

• Question 277:

  A company purchased private lines from two operators. In order to optimize the lines, the company used the 6GP protocol to learn from two route entries that operate off. However, after the enterprise found that this configuration, the traffic of the port route increased greatly, and the network engineering arrangement.

  After investigation, it was found that the traffic of the two operators was passed to each other through the enterprise egress router. Therefore, the enterprise intends to use the routing strategy so that the traffic of the packets of different carriers is no longer passed to each other. Is the configuration in the following figure correct?

  

  A. True
  B. False
  A. True

• Question 278:

  The figure shows an MPLS packet with multiple labels.

  

  Which of the following values for the S field is correct?

  A. S1 = 3, S2 = 2, S3 = 1
  B. S1 = 2, S2 = 1, S3 = 0
  C. S1 = 1, S2 = 1, S3 = 0
  D. S1 = 0, S2 = 0, S3 = 1
  D. S1 = 0, S2 = 0, S3 = 1

• Question 279:

  In the hub-spoke networking shown in the figure, the Hub-PE can be configured to allow repetitive local AS numbers for correct route transmission.

  

  Is this statement TRUE or FALSE? Options:

  A. TRUE
  B. FALSE
  A. TRUE

• Question 280:

  On the network shown in the figure, SW3 is the user gateway and DHCP relay agent. The administrator plans to configure DHCP snooping on SW3 to prevent DHCP attacks .
