• Question 191:

  The figure shows the LSP information of R1 and R3 on an MPLS network. An administrator runs the ping -a 1.1.1.1 3.3.3.3 command on R1. Given this, which of the following statements is true?

  

  A. The Echo Request packet received by R2 carries label 1025, and the Echo Reply packet received by R2 does not carry any label.
  B. The Echo Request packet received by R2 carries label 1025, and the Echo Reply packet received by R2 carries label 1024.
  C. Both the Echo Request and Echo Reply packets received by R2 do not carry any label.
  D. The Echo Request packet received by R2 does not carry any label, and the Echo Reply packet received by R2 carries label 1024.
  A. The Echo Request packet received by R2 carries label 1025, and the Echo Reply packet received by R2 does not carry any label.

• Question 192:

  On the network shown in the figure, IS-IS runs on Rl, 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, Ri, R3, R4, and R6 each establish IBGP peer relationships with R2 and R5. R2 and R5 are RRs, and Rl, R4, R3, and R6 are clients. The IBGP peer relationships are established using LoopbackO. The IP address of LoopbackO on each router is 10.0.X.X/32, and the router ID is 10.0.X.X, where X is the number of the router. Rl 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. For 192.168.2.0/24, R2 preferentially selects the BGP route received from R3.
  B. For 192.168.1.0/24, R3 preferentially selects the BGP route received from R2.
  C. For 192.168.2.0/24, R5 preferentially selects the BGP route received from R3.
  D. For 192.168.1.0/24, R6 preferentially selects the BGP route received from R2.
  A. For 192.168.2.0/24, R2 preferentially selects the BGP route received from R3.
  B. For 192.168.1.0/24, R3 preferentially selects the BGP route received from R2.
  C. For 192.168.2.0/24, R5 preferentially selects the BGP route received from R3.
  D. For 192.168.1.0/24, R6 preferentially selects the BGP route received from R2.

• Question 193:

  In addition to virtual connections, what type of IPv6 address is the source IPv6 address of OSPFv3's Hello text?

  A. IPv6anycast address
  B. unique local address
  C. Global Unicast Address
  D. link-local address
  D. link-local address

• Question 194:

  DRAG DROP

  Both VLAN aggregation and MUX VLAN are deployed on the enterprise network shown in the figure, and all switch interfaces connected to terminals are access interfaces. Given this, match PCI to PC4 with the hosts or servers that they can access on the network. (Note: A host cannot be matched with itself. For example, PCI cannot match PCI.) (Tokens can be reused.)
