Which two statements are correct about tunnels? (Choose two.)
- A . BFD cannot be used to monitor tunnels.
- B . Tunnel endpoints must have a valid route to the remote tunnel endpoint.
- C . IP-IP tunnels are stateful.
- D . Tunnels add additional overhead to packet size.
In a LAN segment, which tie-breaker would spanning tree consider if equal-cost paths exist between two or more switches to the root bridge?
- A . port ID
- B . bridge ID
- C . port priority
- D . interface number
You are configuring an IS-IS IGP network and do not see the IS-IS adjacencies established.
In this scenario, what are two reasons for this problem? (Choose two.)
- A . MTU is not at least 1492 bytes.
- B . IP subnets are not a /30 address.
- C . The Level 2 routers have mismatched areas.
- D . The Io0 interface is not included as an IS-IS interface.
You have configured a GRE tunnel. To reduce the risk of dropping traffic, you have configured a keepalive OAM probe to monitor the state of the tunnel; however, traffic drops are still occurring.
Referring to the exhibit, what is the problem?
- A . For GRE tunnels, the OAM protocol requires that the BFD protocols also be used.
- B . The "event link-adjacency-loss" option must be set
- C . LLDP needs to be removed from the gr-1/1/10.1 interface.
- D . The hold time value must be two times the keepalive-time value
You are troubleshooting an issue where traffic to 192.168.10.0/24 is being sent to R1 instead of your desired path through R2.
Referring to the exhibit, what is the reason for the problem?
- A . R2’s route is not the best path due to loop prevention.
- B . R2’s route is not the best path due to a lower origin code.
- C . R1’s route is the best path due to a higher local preference.
- D . R1’s route is the best path due to the shorter AS path.
You are asked to change the setting for the LSAs age out back to the default value.
In this scenario, which time interval will accomplish this task?
- A . 1800 seconds
- B . 600 seconds
- C . 300 seconds
- D . 3600 seconds
What is the default keepalive time for BGP?
- A . 10 seconds
- B . 60 seconds
- C . 30 seconds
- D . 90 seconds
You want to enable redundancy for the EBGP peering between the two routers shown in the exhibit.
Which three actions will you perform in this scenario? (Choose three.)
- A . Configure BGP multihop.
- B . Configure loopback interface peering.
- C . Configure routes for the peer loopback interface IP addresses.
- D . Configure an MD5 peer authentication.
- E . Configure a cluster ID.
Referring to the exhibit, which two configuration changes must you apply for packets to reach from R1 to R3 using IS-IS? (Choose two.)
- A . On R1, enable Level 1 on the ge-0/0/1 interface.
- B . On R3 disable Level 2 on the ge-0/0/4 interface.
- C . On R1, disable Level 2 on the ge-0/0/1 interface.
- D . On R3 enable Level 1 on the ge-0/0/4 interface.
You are using tunnels in your network. It is important that the routes be specific enough to ensure that the tunnels are established. You need to prevent a route that is new to the network from being used.
In this scenario, which type of route should be used?
- A . multicast
- B . aggregate
- C . static
- D . anycast
