Which configuration mode do you use to apply the mpls ldp graceful-restart command in IOS XE Software?
Answer: D

Refer to the exhibit. ASN 64501 currently reaches the networks under the 10.0.0.0/8 prefix via the North_B router, which is a slow backup link. The administrator of ASN 64502 wants traffic from ASN 64501 to 10.0.0.0/8 to travel via the primary link, North_A. Which change to the network configuration accomplishes this task?
Answer: C
For those who say A is correct... explain how the administrator of 64502 can modify the outgoing traffic of the other AS(64501) using Local pref... Local pref is for traffic leaving your network to prefer one path over the other... and since the issue is with traffic coming into his network not out of his network the only way is to modify MED or a more specific prefix. The only one that will surely get the job done is C because ROUTING IS ALWAYS BASED ON THE MOST SPECIFIC ROUTE REGARDLESS OF AAAAANY OTHER MODIFIERS....

Refer to the exhibit. Router 1 is missing the route for the router 2 loopback 0. What should the engineer change to fix the problem?
Answer: D
It took me 10 minutes to lab it up in GNS3. A. Is wrong, cause the only possible ABR is R2 only. B. Is wrong, cause regardless you adv loopback 0 with the network command as "0.0.0.0" or "0.0.0.255", R1 always see it, once you have applied the correct change. C. Is wrong, cause "hello timers" are not in question here in the outputs shown. D. Is the correct answer, cause you HAVE to not only match the same area numbers, but make them part of AREA 0 (the backbone area), otherwise the adj will never come up.

Refer to the exhibit. Which two topology changes happen to the IS-IS routers? (Choose two.)
Answer: BD
B and D All four routers are Level 1-2, that is by default configuration R1 and R2 are Level 2 neighbors, because the are in different areas R1 and R4 are Level 1 AND Level 2 neighbors NOT Level 2 neighbors only

An engineer is trying to implement BGP in a multihomed architecture. What must the engineer configure to influence inbound path selection?
Answer: A
A is the correct answer. BGP can influence inbound path selection using one of the following BGP attributes: 1. AS-path 2. Multi-Exit Discriminator (MED) Influencing Inbound Path Selection by Modifying the AS_PATH Attribute: router bgp 40000 neighbor 192.168.1.2 remote-as 45000 ! address-family ipv4 neighbor 192.168.1.2 activate neighbor 192.168.1.2 route-map PREPEND out ! route-map PREPEND permit 10 set as-path prepend 40000 40000 https://content.cisco.com/chapter.sjs?uri=/searchable/chapter/content/en/us/td/docs/ios-xml/ios/iproute_bgp/configuration/xe-3e/irg-iproute-bgp-xe-3e-book/irg-prefix-filter.html.xml

Refer to the exhibit. An engineer is updating this network to meet these conditions: ✑ Area 10 will receive inter-area routes and support mutual redistribution of external routes with the extranet. ✑ The ::/0 route is prohibited in Area 10. ✑ Area 11 will receive only the ::/0 route from the ABR. ✑ External route redistribution is not supported in Area 11. ✑ The ABR in Area 11 will advertise no interarea routes. Which two configurations must be performed to meet the requirements? (Choose two.)
Answer: AB
D is not correct because "External route redistribution is not supported in Area 11." And C is not correct by the same reason. E is not correct because "The ABR in Area 11 will advertise not interarea routes". So only A & B correctly work in our scenario.

A network team has failed to implement IS-IS multitopology. What is the reason for it?
Answer: C
Option C is not whether the router IOS supports "router isis" configuration but: " The routing process did not support EXTENDED METRICS"

Refer to the exhibit. An engineer needs to implement this QoS policy on customer's network due to ongoing slow network issues. What will be the effect on the network when the engineer implements this configuration?
Answer: B
After you analyze your network environment, you decide to implement a full separation model for Internet access and MPLS L3VPN services. For which reason do you make this decision?
Answer: B
I would go by option A, since it clearly points to deploying a "Full separation model" between internet access and MPLS services, not centralizing individual services or traffic type. Here you will see some implementations like VRFs to keep EGP and IGP separate: https://community.cisco.com/t5/other-service-provider-subjects/service-provide-mpls-l3vpn-and-internet-access-on-same-router/td-p/3739191

Refer to the exhibit. Which task completes the configuration?
Answer: D
C is not relevant to the question, the configuration is just to establish the BGP neighbor, so the neighbor activate statement is required. D is correct.
