  -- Exhibit -Click the Exhibit button.

  R4 receives BGP prefixes for AS 50 from both R2 and R3. You want to ensure that R4 chooses R3 as the preferred path to reach 50.50.50/24.

  Referring to the information shown in the exhibit, where would you apply a policy containing the parameter local-preference 110 to accomplish this task?

  A. on R3, as import from R1
  B. on R3, as export towards R4
  C. on R2, as import from R1
  D. on R2, as export towards R4
  D. on R2, as export towards R4

  B. EBGP-learned routes are redistributed into any IGPs.
  C. EBGP-learned routes are advertised only to other EBGP peers.
  D. EBGP-learned routes are advertised to other IBGP and EBGP peers.
  B. EBGP-learned routes are redistributed into any IGPs.

  B. Queue 0 has higher priority than Queue 1.
  C. A policer is reclassifying all traffic into Queue 1.
  D. No bandwidth reservation exists on Queue 1.
  D. No bandwidth reservation exists on Queue 1.

• Question 17:

  When traffic is classified on an EX Series switch, which statement is true?

  A. With the default classifier rules applied, voice and video traffic receive their own queues to avoid congestion
  B. With the default classifier, rules applied all traffic that enters an access port is classified as best effort
  C. With the default classifier rules applied, voice traffic is classified as expedited forwarding on trunk ports
  D. If no classifier rules are applied, class of service bits are automatically rewritten on egress to match the class of service assigned on ingress
  B. With the default classifier, rules applied all traffic that enters an access port is classified as best effort
