A network administrator is planning a new network with a segment-routing architecture using a distributed control plane. How is routing information distributed on such a network?

1. A. Each segment is signalled by an SR controller, but each segment makes Its own steering decisions based on SR policy.
2. B. Each segment is signalled by MPLS, and each segment makes steering decisions based on the routing policy pushed by BGP.
3. C. Each segment is signalled by an SR controller that makes the steering decisions for each node.
4. D. Each segment is signalled by a compatible routing protocol and each segment makes its own steering decisions based on SR policy.

An engineer is implementing BGP selective prefix suppression. The router must advertise only 10.16.4.0/24,10.16.5.0/24. and summarized route 10.16.0.0/21. and suppress 10.16.6.0/24. Which configuration must the engineer apply to the router?
A)

B)

C)

D)

1. A. Option A
2. B. Option B
3. C. Option C
4. D. Option D

Correct Answer: B

Refer to the exhibit:

After implementing a new design for the network, a technician reviews the pictured CLI output as part of the MOP.
Which two statements describe what the technician can ascertain from the ImpNull output? (Choose two.)

1. A. Label 0 is used for the prefix displayed but will not be part of the MPLS label stack for packets destined for 192 168.10.10.
2. B. Ultimate Hop Popping is in use for the prefix displayed.
3. C. Label 0 is used for the prefix displayed and will be part of the MPLS label stack for packets destined for 192.168.10.10
4. D. Penultimate Hop Popping is in use for the prefix displayed
5. E. Label 3 is in use for the prefix displayed and will be part of the MPLS label stack for packets destined for 192.168.10.10

Correct Answer: DE

A network engineer is configuring a newly installed PE router at the regional gateway location. The new PE router must use MPLS core routing protocols with the existing P router, and LDP sessions between the two routers must be protected to provide faster MPLS convergence. Which configuration must the engineer perform on the network so that LDP sessions are established?

1. A. Enable communication over TCP port 646 for T-LDP hello messages.
2. B. Enable RSVP-TE FRR on the LDP interface to protect the LDP session between routers.
3. C. Enable LDP session protection on either one of the routers, which allows them to autonegotiate.
4. D. Set the LDP session protection timer on each router to the same value.

Correct Answer: C

A network engineer is testing an automation platform that interacts with Cisco networking devices via NETCONF over SSH. In accordance with internal security requirements:
NETCONF sessions are permitted only from trusted sources in the 172.16.20.0/24 subnet. CLI SSH access is permitted from any source.
Which configuration must the engineer apply on R1?

1. A. configure terminal hostname R1ip domain-name mydomain.com crypto key generate rsaip ssh version 1access-list 1 permit 172.16.20.0 0.0.0.255 netconf ssh acl 1line vty 0 4 transport input ssh end
2. B. configure terminal hostname R1ip domain-name mydomain.com crypto key generate rsaip ssh version 2access-list 1 permit 172.16.20.0 0.0.0.255access-list 1 permit any netconf sshline vty 0 4access-class 1 in transport input ssh end
3. C. configure terminal hostname R1ip domain-name mydomain.com crypto key generate rsaip ssh version 1access-list 1 permit 172.16.20.0 0.0.0.255 access-list 2 permit anynetconf ssh line vty 0 4access-class 2 in transport input ssh end
4. D. configure terminal hostname R1ip domain-name mydomain.com crypto key generate rsaip ssh version 2access-list 1 permit 172.16.20.0 0.0.0.255 netconf ssh acl 1line vty 0 4 transport input ssh end
