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

Refer to the exhibit. A company has been running OSPF and EIGRP on two separate portions of the network. To allow communication flow between these previously isolated parts of the business the networking team just configured R2 to mutually redistribute routes between EIGRP and OSPF R3 has the OSPF routes in its routing table but R1 is failing to receive EIGRP routes for the link between R2 and R3. Which action must the team take to resolve the issue?

• A.Configure R1 with a static route with the next hop set to R3 with the vrf keyword to avoid the global routing table
• B.Configure the redistribution statement with the subnets keyword under the R2 OSPF configuration
• C.Configure a virtual link between R1 and R2 to handle traffic without an assigned area
• D.Configure EIGRP on R1

Refer to the exhibit. A network engineer installed a new router (Router 3) at the regional hub running MPLS services for scalability. Router 3 is connected to the 10.44.4.0/24, 10.44.5.0/24,
10.44.6.0/24, and 10.44.7.0/24 subnets. The new router has been configured for OSPF Area 2, and it is advertising the four connected networks. The engineer noticed that the same networks are listed as interarea summary routes, and they are being flooded into each area on the area borders. Which action resolves the issue?

• A.On router 2, configure a route map to filter the networks.
• B.Under the OSPF configuration on router 3, add area 2 range 10.44.4.0 255.255.252.0.
• C.Under the OSPF configuration on router 2, add area 2 range 10.44.4.0 255.255.252.0.
• D.On router 3, configure an access list to filter the networks.

Refer to the exhibit. ISP_1 uses OSPF and LDP in the backbone. Client_A and Client.B are in the same VRF_Shared. An iBGP session with address family VPNv4 is established between R6 and R14. After a recent replacement of router R13, Client_A has lost its connection to Client_B. A network engineer must troubleshoot the connection from R1 to R23 via ISP_1. Which action must the engineer take to correct the problem?

• A.Set the network 13.13.13.1 0.0.0.0 area 0 command under the OSPF configuration on R13.
• B.Set the next-hop-self command under the BGP configuration on R6.
• C.Set the ip cef command under the global configuration on R6.
• D.Set the mpls label mode vrf VRF_Shared command under the global configuration on R13.
