The ISP_A network is configured with PIMv2 with sparse mode. The engineering team at ISP_A must implement multicast support following RFC 5059 in the network. The RP priority will be 0, and the solution must require limited supervision from the operations team.
Which action must the team take to meet the requirements?
- A . Implement Auto-RP on the candidate RP and the mapping agent only.
- B . Implement Static RP across all routers in the network.
- C . Implement bootstrap router in the network core.
- D . Implement Anycast-RP on edge routers only.
Refer to me exhibit.
A network engineer sets up a multihoming eBGP topology where multiple Autonomous Systems connect to ASN 64501. The engineer wants to block all the routers coming from ASN 64502. but allow all the others.
For that purpose, the following AS Pam prefix 1st s being used:
What must be fixed to achieve this result?
- A . The AS-PATH filter must be defined inside the route-map mode
- B . At the end ip as-path access-list 10 permit .* must be included
- C . The statement must be modified with ip as-path access-list 1 deny _64502_
- D . The statement must CM modified with ip as path access list 1 deny A64502$
An engineer warns to map a multicast IP address to a multicast MAC.
How many bits are used to make the conversion?
- A . high-order 24 bits
- B . higher-order 23 bits
- C . low order 23 bits
- D . lower-order 24 bits
Refer to the exhibit.
A network engineer applied configuration on R5 to summarize all OSPF routes, but R4 is still receiving specific routes from R5. The engineer has confirmed that both R5 and R4 routers are configured with correct summarization configuration but R5 Is not sending the summary routes.
What action must the engineer take to fix the problem?
- A . Remove summarization configuration on R5 and configure it on R4
- B . Configure a sham link between R4 and R5 to support summarization within Area 2
- C . Move R4 and R5 in separate areas as now they maintain the same link-state database
- D . Clear link-state database on both R4 and R5 routers for summarization to work
Which IPv6 prefix format defines the destination of a dynamic 6to4 tunnel?
- A . 2001:db8::/32
- B . 2002::/16
- C . fe80::/10
- D . ff00::/8
Refer to the exhibit.
Excessive routes are flooding from network 150.0.0.0 into AS100. Internet traffic between AS400 and AS300 is working normally. No route controlling mechanism is applied on incoming and outgoing traffic.
Which configuration resolves the issue?
- A . Option A
- B . Option B
- C . Option C
- D . Option D
Refer to the exhibit.
A network operator is troubleshooting TE tunnels and discovers that the soft preemption is not working as desired.
Where should the soft preemption be applied to solve the issue?
- A . on the tail-end device for tunnel-te1 192.168.0.7
- B . under the tunnel-te1 interface on PE1
- C . explicitly for tunnel-te 1 under the Cisco MPLS TE configuration mode after the timeout setting
- D . Under the interface Loopback0 necessary for this deployment type.
While configuring Cisco NSF awareness, a network engineer enters the bgp graceful-restart command after the BGP session is established in a router that runs IOS XE Software. Graceful restart capabilities are not exchanged.
Which two actions should be taken? (Choose two.)
- A . Reload the router
- B . Verity that BGP route dampening is configured
- C . Reduce BGP convergence time
- D . Issue the clear ip bgp * command
- E . Issue the show ip bgp neighbors command.

What is the purpose of ACL type prefix set entries in RPL prefix sets?
- A . They hold IPv4 or IPv6 prefixes that do not match specifications.
- B . They hold IPv4 or IPv6 prefix match specifications.
- C . They hold IPv6 prefix match specifications.
- D . They hold IPv4 prefixes that do not match specifications.
Refer to the exhibit.
An administrator is troubleshooting network issues on a customer’s network PE1 cannot form an LDP relationship with PE2 using LDP ID 192 168.1.1. Due to this connectivity issue, the customer’s routes behind both PE routers cannot be exchanged.
Which action must the administrator take to correct the problem?
- A . Configure PE2 to automatically select its own LDP router ID with 192.168.1.1.
- B . Create a targeted LDP session on PE2 to override the missing routing table entry on PEL
- C . Configure PE1 with a static route to 192 168.1.1.
- D . Enable LDP session protection on the link that P1 uses as the next hop to PE2.
