Refer to the exhibit:

Assume all other configurations are correct and the network is otherwise operating normally. Which conclusion can you draw about the neighbor relationship between routers R1 and R2?

1. A. The neighbor relationship will be up only if the two devices have activated the correct neighbor relationships under the IPv4 address family
2. B. The neighbor relationship is down because R1 believes R2 is in AS 65012.
3. C. The neighbor relationship is up
4. D. The neighbor relationship is down because the loco I-as value for R2 is missing in the R1 neighbor statement

Refer to the exhibit:

An engineer is preparing to implement data plane security configuration. Which statement about this configuration is true?

1. A. Router 2 must configure a route to null 0 for network 192 168.1 0/24 for the RTBH implementation to be complete.
2. B. Router 1 is the trigger router in a RTBH implementation.
3. C. Router 1 must be configured with uRPF for the RTBH implementation to be effective.
4. D. Router 2 is the router receiving the DDoS attack

Correct Answer: B

A network engineer must configure a router for Flexible NetFlow IPFIX export. The IP address of the destination server is 172.17.12.1. The source address must be set to the Loopback0 IPv4 address and exported packets must be set to DSCP CS3. The TTL must be 64 and the transport protocol must be set to UDP with destination port 4739. Which configuration must the engineer apply to the router?

1. A. configure terminalflow exporter EXPORTER-1 destination 172.17.12.1 source Loopback0dscp 3ttl 64export-protocol netflow-v9 transport udp 4739end
2. B. configure terminalflow exporter EXPORTER-1 destination 172.17.12.1 source Loopback0dscp 24ttl 64export-protocol ipfix end
3. C. configure terminalflow exporter EXPORTER-1 destination 172.17.12.1 source Loopback0dscp 24ttl 64export-protocol netflow-v9 transport udp 4739end
4. D. configure terminalflow exporter EXPORTER-1 destination 172.17.12.1 source Loopback0dscp 3ttl 64export-protocol ipfix end

A new PE router is configured to run OSPF as an IGP with LDP on all interfaces. The engineer is trying to prevent black holes after convergence when the PERSON device loses an LDP session with other PE routers. Which action must the engineer take to implement LDP session protection on a new PE router?

1. A. Configure the mpls ldp session protection and mpls label protocol ldp commands on the interfaces on the new PE router that connect to the CENTER routers.
2. B. Configure the mpls ldp discovery targeted-hello accept and mpls ldp session protection commands on the interfaces on the new PE router that connect to the CE routers.
3. C. Configure the new PE router with the mpls ldp session protection command and on neighboring routers that connect to this new PE router.
4. D. Configure the new PE router with the mpls ldp session protection command on interfaces with directly connected neighbors.

Correct Answer: C
