Which condition must be met for TI-LFA to protect LDP tra
c?
- A . For single-segment protection, the PQ node must be LDP and SR-capable.
- B . The protected destination must have an associated LDP label and pre x-SID.
- C . The point of local repair must be LDP-capable.
- D . For double-segment protection, the P and Q nodes must be SR-capable.
Refer to the exhibit. Routers R1 and R2 are connected via a serial link and use the IS-IS routing protocol for route exchange. After a configuration change on R2, IS-IS connectivity is interrupted. A network engineer con rmed that the interfaces are in the UP state and connectivity exists between the two routers.
Which two actions must the engineer perform to resolve the problem? (Choose two.)
- A . Change the hello interface timer to 10 seconds on R1
- B . Change the MTU to 1500 bytes on R2
- C . Change R2 to an IS-IS Level 1 router
- D . Disable padding for hello packets under the serial interface on R2
- E . Enable hello packet padding globally on R1
Refer to the exhibit. The network operations team reported that the access site that is connected to R3 is not connecting to the application server in the data center and that all packets that are sent from the application server to the access site are dropped. The team veri ed that OSPF and BGP peerings are up in BGP AS 65101 and BGP AS 65201. R4 is expected to receive traffic from the application server route via OSPF.
Which action resolves this issue?
- A . Advertise application server 172.16.20.1 in the OSPF routing table on R6
- B . Add the next-hop-self command on R6 to enable R3 iBGP peering
- C . Allow 172.16.20.1 in the BGP advertisement on R3 in the route-map
- D . Remove the route-map on R4 when advertising 172.16.20.1 in BGP to R3
Refer to the exhibit. A network support engineer for ASN 65502 receives a technical support ticket from a customer in ASN 65503 who reports that an eBGP session is down. The engineer determines that the peering failed after a recent change to the device at 192.168.26.2. EDGE-GW-1 must establish an eBGP session with the peering router 192.168.26.2.
Which configuration establishes this session?
- A . configure terminal no router bgp 65502 router bgp 65503 neighbor 192.168.26.2 remote-as 65503 address-family ipv4 neighbor 192.168.26.2 activate end
- B . configure terminal router bgp 65502 address-family ipv4 neighbor 192.168.26.2 activate end
- C . configure terminal no router bgp 65502 router bgp 65503 neighbor 192.168.26.2 remote-as 65123 address-family ipv4 neighbor 192.168.26.2 activate end
- D . configure terminal router bgp 65502 no neighbor 192.168.26.2 remote-as 65503 neighbor 192.168.26.2 remote-as 65123 address-family ipv4 neighbor 192.168.26.2 activate end
Refer to the exhibit.
Which two statements about the IS-IS topology are true? (Choose two.)
- A . R1 and R4 are Level 2 neighbors.
- B . All four routers are operating as Level 1-2 routers.
- C . All four routers are operating as Level 2 routers only.
- D . All four routers are operating as Level 1 routers only.
- E . R1 and R2 are Level 2 neighbors.
Refer to the exhibit. A network operator working for a telecommunication company with an employee id: 1234:56:789 is implementing a Cisco Uni ed MPLS solution.
What is the effect of this implementation?
- A . BGP is deployed between the PEs and ABRs with RFC 9107.
- B . EIGRP is deployed between the PEs and ABRs with RFC 9107.
- C . OSPF is deployed between the PEs and ABRs with RFC 3107.
- D . IS-IS is deployed between the PEs and ABRs with RFC 3107.
Which BGP attribute is used
rst when determining the best path?
- A . origin
- B . AS path
- C . local preference
- D . weight
Which function does RSVP perform in a Cisco MPLS TE environment?
- A . It establishes targeted LDP sessions between neighbors that are directly connected.
- B . It signals to LDP protocol along the path that a Cisco MPLS TE will be configured.
- C . It reserves bandwidth for LDP sessions between routers participating in a Cisco MPLS TE.
- D . It reserves the bandwidth along the path between the head-end and tail-end router.
The NOC team must update the BGP forwarding configuration on the network with these requirements:
✑ BGP peers must establish a neighborship with NSF capability and restart the session for the capability to be exchanged after 120 seconds.
✑ BGP peers must delete routes after 360 seconds of inactivity.
Which action meets these requirements?
- A . Set the BGP restart-time to 120 seconds and the BGP ha-mode sso to 360 seconds.
- B . Set the stalepath-time to 120 seconds and the BGP restart-time to 360 seconds.
- C . Set the BGP ha-mode sso to 120 seconds and the BGP restart-time to 360 seconds.
- D . Set the BGP restart-time to 120 seconds and the stalepath-time to 360 seconds.
An engineer working for a telecommunication company with an employee ID: 1234:56:789 must configure an OSPF router in a multivendor network so that it performs NSF in the event of a route processor switchover.
