  BGP is running on the network, and CE1 currently prefers routes to the internet via PE 1 A network engineer must manipulate the BGP routes that CE1 receives from PE2 to be more desirable The engineer configured a route map using MED and applied it on CE1 outbound from PE2. However, after a BGP soft reset. PE1 is still preferred. Which action must the engineer take so that PE2 is chosen as the next hop?

  A. Update the route map to use only weight to manipulate the path.
  B. Configure the route map with MED and local preference to manipulate the route outbound
  C. Apply the route map on CE1 In the inbound direction.
  D. Configure the route map with AS path prepend to manipulate the AS path to exit the autonomous system
  B. Configure the route map with MED and local preference to manipulate the route outbound

• Question 146:

  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
  D. At the end, ip as-path access-list 10 permit.* must be included

• Question 147:

  Refer to the exhibit.

  

  A network consultant is updating the company's 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.
  B. Configure Cisco Express Forwarding on all routers in the MPLS network.

• Question 148:

  Refer to the exhibit.

  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.
  B. under the tunnel-te1 interface on PE1

• Question 149:
