Refer to the exhibit. While applying the configurations on two routers, an engineer notices that OSPF adjacency between them remains down. Through the ping test, the engineer confirmed that both the routers have Layer 3 reachability between them. Which action should the engineer take to make the adjacencies to full?

  1. Enable OSPF just inside the router OSPF process, not in the interfaces of any router
  2. Delete the area 0 authentication message-digest command from the OSPF process in R1
  3. Enter the command ipospf authentication in R2 interface
  4. Delete the area 0 authentication message-digest command from the OSPF process in R2

What are three requirements for a static IPv6-in-IPv4 tunnel? (Choose three.)

  1. A dynamic IPv6 address must be configured
  2. A dynamic IPv4 address must be configured
  3. A static IPv4 address must be configured
  4. A static IPv6 address must be configured
  5. Each tunnel endpoint must support IPv4 and IPv6
  6. Cisco Express Forwarding must be enabled

What are two differences between OSPF and IS-IS? (Choose two.)

  1. Unlike IS-IS routers, an OSPF router belongs to only one area in addition to the backbone area
  2. OSPF uses a router ID to identify a router, and IS-IS uses a system ID
  3. OSPF is a link-state routing protocol, and IS-IS is a distance-vector routing protocol
  4. Unlike OSPF, IS-IS supports virtual links
  5. OSPF elects a DR and BDR, and IS-IS elects a DIS

Answer(s): B,E



Refer to the exhibit. Router1 and Router2 have shared routes in the OSPF database, but the routes are missing from their routing tables. Checking the prefix-list configuration on both routers, the engineer confirmed all networks are allowed. What action should the engineer take to fix the problem?

  1. Configure interface Serial1/0 on Router1 as a point-to-point interface
  2. Configure the two routers with different process IDs
  3. Switch the DR and BDR roles between the two routers
  4. Configure the two routers with different hello and dead timer values

Answer(s): A
