  Correct Answer: B

• Question 42:

  Refer to the exhibit.

  

  This network is deployed with all connected links configured to run IS- IS.

  Which action corrects the issue so that all routes are shared among the routers?

  A. Configure all routers to reside in toe area.

  B. Configure RI and RS as Level 1"Level 2

  C. Configure R3 as a Level 2 we.

  D. Configure R5 in the same as RI,

  Correct Answer: A

• Question 43:

  Refer to the exhibit.

  

  CE1 and CE2 use connectivity over the service provider cloud to reach CE3 In the event of a link failure in the service provider cloud which BGP feature relies on IGP convergence to quickly assist in the installation of a backup path?

  A. BGP graceful restart

  B. BGP route dampening

  C. BOP PIC core

  D. BGP confederations

  Correct Answer: C

• Question 44:

  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 the subnet range with the network command under the IS-IS process.

  B. Configure RI as a Level 1 device.

  C. Redistribute both routes into the ISIS process.

  D. Configure a summary route for Level 1-Level 2 devices.

  E. Configure a summary route for Level 1 devices.

  Correct Answer: DE

• Question 45:

  An engineer warns to map a multicast IP address to a multicast MAC How many bits are used to make the conversion?

  A. high-order 24 bits

  B. higher-order 23 bits

  C. low order 23 bits

  D. lower-order 24 bits

  Correct Answer: C

• Question 46:

  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 3, configure an access list to filter the networks.

  B. On router 2, configure a route map to filter the networks.

  C. Under the OSPF configuration on router 3. add area 2 range 10.44.4.0 255.255.252.0.

  D. Under the OSPF configuration on router 2, add area 2 range 10.44.4.0 255.255.252.0.

  Correct Answer: D

• Question 47:

  What is a requirement of PIM-SM?

  A. It requires Cisco Express Forwarding to be enabled.

  B. It must be enabled on loopback interfaces only

  C. It requires OSPF to be configured on the network.

  D. It must use an RP

  Correct Answer: D

• Question 48:

  Refer to the exhibit.

  

  

  Multicast traffic destined from T1 and T2 routers to RP routers works well. A network engineer observes problems with multicast traffic flows between Site-A and Site-B. Site-A users fail to receive multicast stream on Site-B via RPTY site, while Site-B users fail to receive multicast stream on Site-Avia RPTZ site.

  Which action must be implemented to resolve the issues?

  A. Establish MDSP peering with interface IP subnet.

  B. Configure Site-A and Site-B in 10.80.14804

  C. Allow the OSPF and MSDP packets on the firewall.

  D. Configure direct OSPF peering between Site-A and Ste-B

  Correct Answer: C

• Question 49:

  How does SRv6 function on the control plane?

  A. It enables SRH-capable nodes to terminate IPv6 packets at the network egress to carry the SRv6 locator.

  B. The Ingress node of the SR domain adds a uSlD format IPv6 header to carry the SRv6 locator.

  C. The ingress node of the SR domain swaps the SRv6 header for the IPv6 header

  D. The egress node of SR domain imposes a new outer header

  Correct Answer: B

• Question 50:

  Refer to the exhibit.

  

  A network engineer configured three new PE routers to expand the network.

  The new routers run in the IS-IS routing protocol and reside in the data center in the same exchange as the existing routers. However, the network is now experiencing suboptimal routing.

  The Layer 2 configuration and VLANs are configured correctly to provide segregation between networks, but the Level 1 routes are not being converted to Level 2 routes.

  Which action resolves the issue?

  A. On Router 1, redistribute the routes into IGP.

  B. On Router 1, summarize internal routes between areas.

  C. On Router 2, redistribute the routes into IGP.

  D. On Router 2. summarize internal routes between areas.

  Correct Answer: D
