Q5. A Service Provider connects to a client site that has two CEs. These CEs have a backdoor link for backup. OSPF is used as the routing protocol in this environment. You want to ensure that client traffic prefers the service provider connections for routing instead of the secondary connection. Which option describes the default behavior and the action that accomplishes your goal?
A. The routes to the Service Provider are not preferred, due to the increased OSPF cost through the service provider network. Ensure that the cost on the links to the service provider are lower than the secondary connection.
B. The routes to the Service Provider are seen as external type 1 in the OSPF database. Configure a domain ID that is the same across all PEs, to ensure that customers see routes as intra-area.
C. The routes to the Service Provider are seen as inter-area OSPF routes through the network. Configure a sham link to create a new intra-area path across the service provider network between the PE routers that service the client.
D. The routes to the Service Provider are seen as equal and cause nondeterministic traffic patterns. Ensure that the secondary connection has a higher cost than the links to the service provider.
Answer: C

Q8. A MPP has been implemented in a Cisco IOS-XR device. Which are the two results that will occur? (Choose two.)
A. If MPP is disabled and a protocol is activated, all interfaces cannot pass traffic
B. MPP configuration changes doesn't affect active sessions established before the changes
C. RP/DRP Ethernet Interfaces are not default out-of-band interfaces
D. Management traffic to RP from all non-MPP interfaces is dropped

Q9. Refer to the exhibit. R1 and R2 are multicast routers running PIM over Serial1/0. The PIM adjacency on R1 is not forming with the given configuration. What command can be entered on R1 to resolve the issue?
A. no access-list 100 deny 103 any any
B. no access-list 100 deny udp any anyeq 103
C. no access-list 100 deny ip any host 224.0.0.1
D. no access-list 100 deny ip any host 224.0.0.2
Answer: A
Explanation:
All PIM protocols share a common control message format. PIM control messages are sent as raw IP datagrams (protocol number 103), either multicast to the link-local ALL PIM
ROUTERS multicast group, or unicast to a specific destination.

Q15. Refer to the exhibit.
A company has a requirement to provide communication among remote sites via multipoint GRE tunnels. This communication is not working yet. Which is the root cause of this issue?
