Refer to the exhibit.

A network operator is getting the route for 10.11.11 0/24 from two upstream providers on
#XR3. The network operator must configure #XR3 to force the 10.11.11.0/24 prefix to route via next hop of 10.0.0.9 as primary when available. Which of these can the operator use the routing policy language for, to enforce this traffic forwarding path?

A. weight of 100 on the prefix coming from 192.168.0.1
B. higher local preference on the prefix coming from 192.168.0.1
C. weight of 0 on the prefix coming from 192.168.0.2
D. lower local preference on the prefix coming from 192.168.0.2

正解：C

解説：
Because Weight is the first attribute in path selection algorithm and is 0 for eBGP routes by default. If we set it to 0, router will continue from weight to the bottom, and when comparing neighbor router IDs it will find 192.168.0.1 less than 192.168.0.2 and st path will be selected as the best

Refer to the exhibit.

Refer to the exhibit. MPLS traffic from 192.168.4.0/24 to 192.168.5.0/24 is failing to pass over the link from R4 to R2. The engineer verified that:

All routers reach all networks via OSPF.
MPLS traffic from 192.168.1.0/24 to 192.168.3.0/24 is passing normally over the link from R1 to R2.
Which action resolves the issue?

A. On router R4, configure the mpls label protocol Idp command on all serial interfaces.
B. On router R2, configure the mpls label protocol Idp command on the interface.
C. On router R2, configure the mpls ip command on the SIO/O/4 interface.

質問 # 57
In a PIM-SM environment, which mechanism determines the traffic that a receiver receives?

A. The receiver explicitly requests its desired traffic from the RP on the shared tree.
B. The RP on the shared tree floods traffic out of all PIM configured interfaces.
