Question 1

Refer to the exhibit. What is the relationship between Router 1 and Router 2?

• A. Router 1 centrally learns the topology of the network to aid in SR-TE path selection, and Router 2 is a node that feeds Router 1 topology information
• B. Router 1 and Router 2 are participating in SR-TE tunnels and are both head-end routers
• C. Router 1 and Router 2 centrally learn the topology of the network to aid in SR-TE path selection for peers
• D. Router 2 is the head-end router in an SR-TE tunnel, and it is learning topology of the network from the PCE enabled on Router 1

Question 2

A network engineer recently deployed a wireless network for users at a new office to join video conferences wirelessly. The existing network consists of routers that are configured for EIGRP and BGP, which are located at several data centers in different physical locations. The engineer configured PIM-SSM within a single domain from a single source. However, during the testing phase, the video conference failed to work for any of the users. The IPs are reachable and firewalls in the network are configured correctly to allow the traffic. Which action resolves the issue?

• A. Configure PIM sparse mode to replace PIM-SSM.
• B. Configure PIM dense mode to replace PIM-SSM.
• C. Configure the devices to send join messages toward a multicast SPT.
• D. Configure PIM dense mode with multidomain multicast.

Question 3

Refer to the exhibit.



Routers R1 and R2 reside in AS 65530, which is multihomed to the Internet. A network engineer expects devices in the AS to use R2 to access the Internet, but they are using R1 as the exit point from the AS. Which action corrects the problem?

• A. Add a sequence number to the route map to remove the implicit deny.
• B. Change the route map direction in the neighbor statement to out.
• C. Configure the route map with a local preference of 200 or higher.
• D. Remove the neighbor statements from the address family configuration and activate the neighbor globally on R1.

Question 4

Refer to the exhibit. While configuring router 2 with all the default values, a network engineer cannot see any route received in router 1. How should the engineer solve the issue?

• A. Modify the IP address or mask of the interface to a valid one
• B. Set up a priority different than 0 in the interface
• C. Modify the router ID to be the interface IP on the serial
• D. Set the network type in S1/0 to point-to-point

Question 5

Refer to the exhibit.



A network consultant is updating the companys MPLS solution and configuring several new PE devices to enable full communication among PE devices connected to the network. The updates must ensure the redundancy and scalability of the network. The egress LSR is configured with mpls ldp explicit-null. While configuring the given PE router to be adjacent to the egress LSR, the consultant notices that MPLS forwarding is not working in the network. Which action resolves the issue?

• A. Open TCP and UDP ports 179.
• B. Configure Cisco Express Forwarding on all routers in the MPLS network.
• C. Configure MVRF on all routers in the MPLS network.
• D. Open TCP and UDP ports 464.

Question 6

Refer to the 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 routes coming from ASN 64502 but allow all the others. For that purpose, the following AS Path prefix list is being used:

(config)#ip as-path access-list 10 deny _64502$

What must be fixed to achieve this result?

• A. The AS-PATH filter must be defined inside the route-map mode
• B. The statement must be modified with ip as-path access-list 1 deny_64502_
• C. The statement must be modified with ip as-path access-list 1 deny ^64502$
• D. At the end, ip as-path access-list 10 permit.* must be included

Question 7

Refer to the exhibit. After troubleshooting an OSPF adjacency issue, routers 1, 2, and 3 have formed OSPF neighbor relationships. Which statement about the configuration is true?

• A. Router 2 receives a Type 5 LSAs from router 1 for its connected subnets
• B. Router 2 uses router 3 as the next hop for 192.168.0.0/24
• C. Router 2 uses router 1 as the next hop for 192.168.0.0/24
• D. Router 2 receives a Type 7 LSAs from router 3 for its connected subnets

Question 8

Refer to the exhibit. CE1 is the gateway router into the provider network via PE1. A network operator must inject a default route into OSPF area 0. All devices inside area 0 must be able to reach PE1. Which configuration achieves this goal?
A.

B.

C.

D.

Question 9

Which difference must an engineer consider when choosing whether to implement OSPF or IS-IS as the routing protocol on the network?

• A. The OSPF DR election process is deterministic, and the IS-IS DS election process is not deterministic.
• B. To support fast convergence, OSPF uses the LSA arrival timer and IS-IS uses the PRC-interval timer.
• C. IS-IS supports ordinary, stub, totally-stub, and NSSA areas, but OSPF supports only stub areas.
• D. IS-IS links are associated with either a Level 1 area or a Level 2 area at one time, but OSPF links are associated with multiple areas at one time.

Question 10

Refer to the exhibit. There is a connectivity issue between Customer-1 and Customer-2. File servers between the customers cannot send critical data. R3 routes are missing from the routing table on the Customer-1 router. All interfaces on Customer-1 are up. Which configuration must be applied to router R2 to correct the problem?

• D. None
