• Question 93:

  Scenario

  Refer to the topology. Your company has decided to connect the main office with three other remote branch offices using point-to-point serial links. You are required to troubleshoot and resolve OSPF neighbor adjacency issues between the

  main office and the routers located in the remote branch offices.

  Use appropriate show commands to troubleshoot the issues and answer all four questions.

  Instructions

  An OSPF neighbor adjacency is not formed between R3 in the main office and R4 the Branch1 office. What is causing the problem?

  A. There is an area ID mismatch.
  B. There is a Layer 2 issue; an encapsulation mismatch on serial links.
  C. There is an OSPF hello and dead interval mismatch.
  D. The R3 router ID is configured on R4.
  A. There is an area ID mismatch.

  ---

  A show running-config command on R3 and R4 shows that R4 is incorrectly configured for area 2:

  

  

• Question 94:

  Refer to the exhibit. The network is converged.

  After link-state advertisements are received from Router_A, what information will Router_E contain in its routing table for the subnets 208.149.23.64 and 208.149.23.96?

  

  A. O 208.149.23.64 [110/13] via 190.173.23.10, 00:00:07, FastEthernet 0/0 O 208.149.23.96 [110/13] via 190.173.23.10, 00:00:16, FastEthernet 0/0
  B. O 208.149.23.64 [110/1] via 190.172.23.10, 00:00:07, Serial 1/0 O 208.149.23.96 [110/3] via 190.173.23.10, 00:00:16, FastEthernet 0/0
  C. O 208.149.23.64 [110/13] via 190.172.23.10, 00:00:07, Serial 1/0 O 208.149.23.96 [110/13] via 190.172.23.10, 00:00:16, Serial 1/0 O 208.149.23.96 [110/13] via 190.173.23.10, 00:00:16, FastEthernet 0/0
  D. O 208.149.23.64 [110/3] via 190.172.23.10, 00:00:07, Serial 1/0 O 208.149.23.96 [110/3] via 190.172.23.10, 00:00:16, Serial 1/0
  A. O 208.149.23.64 [110/13] via 190.173.23.10, 00:00:07, FastEthernet 0/0 O 208.149.23.96 [110/13] via 190.173.23.10, 00:00:16, FastEthernet 0/0

  Router_E learns two subnets subnets 208.149.23.64 and 208.149.23.96 via Router_A through FastEthernet interface. The interface cost is calculated with the formula 108 / Bandwidth. For FastEthernet it is 108 / 100 Mbps = 108 / 100,000,000 = 1. Therefore, the cost is 12 (learned from Router_A) + 1 = 13 for both subnets -B is not correct. The cost through T1 link is much higher than through T3 link (T1 cost = 108 / 1.544 Mbps = 64; T3 cost = 108 / 45 Mbps = 2) so surely OSPF will choose the path through T3 link -> Router_E will choose the path from Router_A through FastEthernet0/0, not Serial1/0 -C and D are not correct. In fact, we can quickly eliminate answers B, C and D because they contain at least one subnet learned from Serial1/0 -they are surely incorrect.

• Question 95:

  Which three responses does TACAS+ give while querying. (Choose three.)

  A. error
  B. accept
  C. continue
  D. persist
  E. fault
  A. error
  B. accept
  C. continue

• Question 96:

  In the Frame Relay network, which IP addresses would be assigned to the interfaces with point-to-point PVCs?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  C. Option C

  ---

  DLCI 16 and DLCI 19 need to act like a point-to-point link and will therefore need to be on the same network as will DLCI 17 and DLCI 28. With this information we can see that option "B" is the only option that has the corresponding DLCI's on

  the same network based on the ip addresses and subnetmask.

  Option "D" is incorrect because, this would put the same network on both interfaces of the R2 router. Option "A" is similar.

• Question 97:

  Which two statements identify differences between single-homed and dual-homed WAN topologies? (Choose two.)

  A. Dual-homed topologies provide greater redundancy than single-homed topologies
  B. Only dual-homed connections require dynamic routing to the ISP
  C. Single-homed topologies are more costly to an enterprise than dual-homed topologies
  D. Only dual-homed connections are connected to the same ISP
  E. Single-homed topologies are more appropriate for small-business networks than dual-homed topologies
  A. Dual-homed topologies provide greater redundancy than single-homed topologies
  E. Single-homed topologies are more appropriate for small-business networks than dual-homed topologies

• Question 98:

  Refer to the topology shown in the exhibit. Which ports will be STP designated ports if all the links are operating at the same bandwidth? (Choose three.)

  

  A. Switch A -Fa0/0
  B. Switch A -Fa0/1
  C. Switch B -Fa0/0
  D. Switch B -Fa0/1
  E. Switch C -Fa0/0
  F. Switch C -Fa0/1
  B. Switch A -Fa0/1
  C. Switch B -Fa0/0
  D. Switch B -Fa0/1

  D. show running-configuration eigrp
  C. show ipv6 eigrp neighbors
