sanjose#clear ip bgp 10.1.1.1 in prefix-filter
A. The sanjose router will perform an outbound soft reconfig to the 10.1.1.1 neighbor.
B. The sanjose router will send out the ORF prefix-list so that a new route refresh will be received from the
1.1.1 neighbor.
C. The 10.1.1.1 router will perform an inbound soft reconfig on the updates from the sanjose neighbor.
D. The 10.1.1.1 router will send out the ORF prefix-list so that a new route refresh will be received from
the sanjose neighbor.
E. The bgp session between the sanjose and the 10.1.1.1 router will be reset so that all the new bgp
updates from the 10.1.1.1 router can be processed by the inbound prefix-list at the sanjose router.
F. The bgp session between the sanjose and the 10.1.1.1 router will be reset so that all the new bgp

NO.9 For which purpose is the command mpls ldp maxhops used?
A. In large ATM-MPLS networks, the LFIB can become too large and it may be necessary to limit the
maximum diameter of the MPLS LSPs.
B. Because downstream-on-demand label allocation uses hop count to control loop detection, it maybe
necessary to limit the maximum diameter of the MPLS network.
C. Because end-to-end delay can cause problems with some voice applications, it may be necessary to
limit the maximum diameter of the MPLS network.
D. When interconnecting large frame mode MPLS and cell mode networks it may be necessary to limit the
maximum network diameter to prevent forwarding loops.
