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$

Refer to the exhibit.

Routers R1, R2. R3, and R4 have been configured to run OSPF. and router R5 is running EIGRP Traffic from R1 to R5 is expected to pass via R4. but OSPF routing has calculated the best path via R3. Which action corrects the problem?

A. Configure R3 to use metric-type 1 with a higher metric than R4.

B. Configure R1 with a static route to the R5 networks and set R5 as the next hop.

C. Reconfigure R1 in Area 0.

D. Change the metric-type value on R3 to 2.

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

Refer to the exhibit.

An engineer is comparing these RPL and route map configurations. Which two conclusions will the engineer reach? (Choose two.)

A. RPL is applying policy only on BGP IPv6 address families, but the route map is applying policy on BGP IPv4 and IPv6 address families.

B. RPL and the route map are applying only local preference 50 for prefix 172.22.0.0/16.

C. RPL is applying local preference 100 and community (2:100) for multiple prefixes, but the route map is applying default local preference for multiple prefixes

D. RPL is applying local preference 50 and community (2:666) for prefix 172.22.0.0716. but the route map is applying only local preference 50 for the same prefix

E. RPL is applying local preference 50 and community (2:666) for all prefixes, but the route map is applying only local preference 50 for all prefixes.

What are two differences between OSPF and IS-IS? (Choose two.)

A. OSPF is a link-state routing protocol, and IS-IS is a distance-vector routing protocol.

B. OSPF uses a router ID to identify a router, and IS-IS uses a system ID.

C. OSPF elects a DR and a BDR, and IS-IS elects a DIS.

D. Unlike OSPF. IS-IS supports virtual links.

E. Unlike IS-IS routers, an OSPF router belongs to only one area in addition to the backbone area.

Topology

Tasks

Configure and verify an OSPF neighbor adjacency between R1 and R2 in OSPF area 0 according to the topology to achieve these goals:

1. R1 pings the Loopback0 interface of R2. Use interface-level configuration to complete this task.
2. R2 pings the Loopback0 interface of R1. Use interface-level configuration to complete this task.
3. R2 receives a single summary route 172.16.100.0/22 for networks 172.16.100.0/24, 172.16.101.0/24, and 172.16.103.0/24.

Refer to the exhibit.
