Q13. Users are complaining of intermittent high packet loss for seconds at a time. The engineer troubleshooting the issue finds that a TenGigE link is bouncing for milliseconds at a time, causing the traffic path to reconverge onto a congested FastEthernet link.

A. decrease the carrier-delay up on both sides of the link 

B. disable keepalives and BFD 

C. decrease the carrier-delay down on both sides of the link 

D. increase the carrier-delay up on both sides of the link 

E. increase the carrier-delay down on both sides of the link

mpls ldp label 

allocate global prefix-list List1 

B. mpls ldp label 

allocate global host-routes 

C. access-list 1 permit subnet wildcard 

mpls ldp neighbor neighbor_ip labels accept 3 

D. mpls ldp password required for 10

What two BGP deployment options will accomplish this design goal? (Choose two.) 

A. On the router handling the secondary link, advertise routes with a MED value of 0. 

B. On the router handling the primary link, set the weight for all incoming routes to be a value of 0. 

C. On the router handling the secondary link, advertise all routes with a longer AS-PATH value. 

D. On the router handling the primary link, advertise all routes with a longer AS-PATH value. 

E. On the router handling the secondary link, set the local preference for all incoming routes to be a value of 0.
