How can you prevent multihomed customers with connections to two service providers from acting as a transit AS?

A. Use MED to influence the inbound traffic from the ISPs.

B. Use conditional advertisements when sending BGP updates to the ISPs.

C. Enable BGP synchronization on all the customer routers.

D. Use static routing to the ISPs.

Refer to the Cisco IOS XR route policy exhibit.

route-policy new
if community matches-any test then
set local-preference 10
elseif community matches-every foo then
set local-preference 20
else
pass
endif
end-policy

Which two statement are correct?

A. The "match-any" option indicates matching either the standard community or extended community.

B. "test" and "foo" are references to the community sets.

C. Routes that match both the "test" and "foo" conditions will have their local preference set to 20.

D. All non-matching routes will be permitted.

A. subnetted routes

B. /32 host routes

C. Type 1 external routes

D. tagged static routes

E. Type 2 external routes

Refer to the exhibit. Which Cisco IOS XR configuration is missing to complete the configuration task of enabling BFD with only the OSPF peer over the gi0/3/0/1 interface in area 0?

router ospf 100
bfd minimum-interval 2
bfd multiplier 20
area 0
interface GigabitEthernet0/3/0/1
interface GigabitEthernet0/3/0/2
end

A. bfd fast-detect also needs to be enabled for the OSPF area under area 0.
RP/0/RSP0/CPU01(config-ospf-ar)#bfd fast-detect

B. bfd fast-detect also needs to be enabled globally on the router.
RP/0/RSP0/CPU01(config)#bfd fast-detect

C. bfd fast-detect also needs to be enabled globally under router ospf 100.
RP/0/RSP0/CPU01(config-ospf)#bfd fast-detect

D. bfd fast-detect also needs to be enabled on the gi0/3/0/1 interface under interface gi0/3/0/1.
RP/0/RSP0/CPU01(config-if)#bfd fast-detect

E. bfd fast-detect also needs to be enabled for the OSPF interface under area 0 interface gi0/3/0/1.
RP/0/RSP0/CPU01(config-ospf-ar-if)#bfd fast-detect
