Router 1 is running the IS-IS routing protocol, and it is preconfigured with LDP and segment routing. Which configuration must the engineer apply under router isis 111 on Router 1 to implement TI-LFA on the link to Router 2 without disrupting traffic to Router 3?

A. interface GigabitEthernet0/0/1
fast-reroute per-prefix ti-lfa enable B. interface GigabitEthernet0/0/1
address-family ipv4 unicast
fast-reroute per-prefix
fast-reroute per-prefix ti-lfa C. interface GigabitEthernet0/0/1
fast-reroute prefix enable D. interface GigabitEthernet0/0/1
address-family ipv4 unicast
fast-reroute per-prefix

Correct Answer: B

Question 8

Refer to the exhibit. A network engineer is investigating a report of packet drops between the branch site and the central site.
- The two sites are connected via OSPF and RSVP-TE tunnels.
- Traffic from the central site to the branch site is passing normally.
- Technicians at both sites successfully ping the loopback IP addresses on routers R1 and R2.
Which configuration corrects the packet-drop problem?

A. R1(Config)# interface Tunnel222
R1(Config-if)# tunnel mpls traffic-eng bandwidth 33000 B. R2(Config)# interface Ge0/0
R2(Config-if)# ip rsvp bandwidth 33000 3300 C. R1(Config)# interface Ge0/0
R1(Config-if)# ip rsvp bandwidth 33000 3300 D. R2(Config)# interface Tunnel333
R2(Config-if)# tunnel mpls traffic-eng bandwidth 33000

Correct Answer: C

Question 9

What Is a characteristic of a segment routing mapping server?

A. It must be placed in the core of the network. B. It must have an IGP adjacency. C. It applies SID mappings from one IGP instance to another IGP instance. D. It serves multiple VRFs.

Correct Answer: B

Question 10

Refer to the exhibit. Routers R1, R2, R3, and R4 have been configured to run OSPF, and router R5 is running EIGRP. Traffic from R1 to R5 is expected to pass via R4, but OSPF routing has calculated the best path R3. Which action corrects the problem?

A. Configure R3 to use metric-type 1 with a higher metric than R4. B. Change the metric-type value on R3 to 2. C. Reconfigure R1 in Area 0. D. Configure R1 with a static route to the R5 networks and set R5 as the next hop.

Correct Answer: B

Question 11

Refer to the exhibit. All routers on this network have been configured with PIM-SM, and R1 is the rendezvous point. However, when asymmetric routing is implemented to modify link usage, the network begins to drop certain multicast traffic. Which action corrects the problem?
