Refer to the exhibit. A network engineer at a large ISP with an employee ID 487694052 started to configure OSPF on two routers. The engineer notices that router 1 learned about network
20.20.20.0/24 from router 2, but router 2 did not learn about 10.10.10.0/24 from router 1 Layer 2 and Layer 3 connectivity are working between the two routers and the physical connection between the devices is functioning. Which action must the engineer take to resolve the issue?

• A.Replace the router 1 OSPF network configuration with network 10.10.10.0 0.0.0.255 area 0.
• B.Replace the router 2 OSPF network configuration with network 10.10.10.0 0.0.0.255 area
• C.On router 1 configure a route map with a distribution list for the 10 10.10 0/24 network.
• D.On router 2 configure a route map with a distribution list for the 10.10.10.0/24 network

How does the SRv6 IS-IS Flexible Algorithm function on the data plane?

• A.It applies path computation algorithms to learn the topology and compute a pair of disjoint LSPs.
• B.It uses the TE metric in its path calculations to optimize the cumulative TE metric.
• C.It uses the IGP metric in its path calculations to optimize reachability.
• D.It automatically delivers traffic to the destination over an engineered path computed by the IGP.

Which difference must an engineer consider when choosing whether to implement OSPF or IS-IS as the routing protocol on the network?

• A.The OSPF DR election process is deterministic, and the IS-IS DS election process is not deterministic.
• B.To support fast convergence, OSPF uses the LSA arrival timer and IS-IS uses the PRC-interval timer.
• C.IS-IS supports ordinary, stub, totally-stub, and NSSA areas, but OSPF supports only stub areas.
• D.IS-IS links are associated with either a Level 1 area or a Level 2 area at one time, but OSPF links are associated with multiple areas at one time.

Refer to the exhibit. A network consultant is updating the company's MPLS solution and configuring several new PE devices to enable full communication among PE devices connected to the network. The updates must ensure the redundancy and scalability of the network. The egress LSR is configured with mpls Idp explicit-null While configuring the given PE router to be adjacent to the egress LSR. The consultant notices that MPLS forwarding is not working in the network.
Which action resolves the issue?

• A.Open TCP and UDP ports 179
• B.Open TCP and UDP ports 464
• C.Configure MVRF on all routers in the MPLS network
• D.Configure Cisco Express Forwarding on all routers in the MPLS network

Router 1 is connected to router 2 on interface TenGigE0/1. Which interface provides the alternate path to 172.16.200.9/32 when the link between router 1 and router 2 goes down?

• A.A primary path must be manually installed
• B.A backup path must be statically installed
• C.TenGigE0/2 interface provides the alternate path
• D.TenGigE0/1 interface provides the alternate path
