Refer to the exhibit. After troubleshooting an OSPF adjacency issue, routers 1, 2, and 3 have formed OSPF neighbor relationships.
Which statement about the configuration is true?

• A.Router 2 uses router 1 as the next hop for 192.168.0.0/24
• B.Router 2 receives a Type 5 LSAs from router 1 for its connected subnets
• C.Router 2 uses router 3 as the next hop for 192.168.0.0/24
• D.Router 2 receives a Type 7 LSAs from router 3 for its connected subnets

Which statement about enabling segment routing for IGPs is true?

• A.Segment routing must first be enabled under then routing process and then globally
• B.Segment routing can be enabled only globally
• C.Segment routing can be enabled only under the routing process
• D.Segment routing must first be enabled globally and then under the routing process

Refer to the exhibit. The branch office in area 10 is connected to HQ via Frame Relay uplinks with bandwidth constraints. After a recent implementation of QoS on the R2 and R3 networks the system has been logging %SYS-2-MALLOCFAIL: Memory allocation of 65536 bytes failed from
0x224E321, alignment 0 messages. To reduce traffic load and memory utilization on R2 and R3 the network engineer configured R1 to announce only one user subnet per location by issuing the summary address 192.168.0.0 255.255.248.0 command en R1. However, the engineer noticed that router R2 still has two routes and a summary address from HQ and R3 also has two routes from HQ. Which two actions must the engineer take on R1 to fix the issue so that only one route is announced? (Choose two.)

• A.Configure a summary route for Level 1 devices.
• B.Configure the subnet range with the network command under the IS-IS process.
• C.Configure RI as a Level 1 device.
• D.Configure a summary route for Level 1-Level 2 devices.
• E.Redistribute both routes into the ISIS process.

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

Refer to the exhibit. An engineer at a large ISP is troubleshooting suboptimal routing on a customer's IS-IS network with multiple Level 1-2 routers. The network consists of numerous routers that are configured for MPLS. When IS-IS picks the closest Level 1-2 router to exit the area, suboptimal routing occurs in Area 8 and Area 10. The other IGP protocols are running correctly, and the IS-IS adjacency between routers is established. Which action resolves the issue?

• A.Configure each interface as either Level 1 or Level 2 circuit type on router 1.
• B.Disable advertisement of the default route on router 2.
• C.Configure the router as DIS for each of the interfaces on router 1.
• D.Redistribute Level 2 prefixes into Level 1 on router 2.
