• Question 224:

  Refer to the exhibit.

  

  An engineer working for a private telecommunication company with an employee id: 4233:46:364 notices that the customer network going through AS30-AS65001-AS65000 is experiencing packet drops when it accesses an application at 172.16.20.1/32 In the DC cloud.

  The BGP link between AS20 and AS30 is inaccessible because of a fiber cut. Routers RL, RN, and RZ are configured with confederation identifier 10.

• Question 226:

  Refer to the exhibit.

  

  What is the relationship between Router 1 and Router 2?

  A. Router 1 centrally learns the topology of the network to aid in SR-TE path selection, and Router 2 is a node that feeds Router 1 topology information.
  B. Router 1 and Router 2 are participating in SR-TE tunnels and are both head-end routers.
  C. Router 1 and Router 2 centrally learn the topology of the network to aid in SR-TE path selection for peers.
  D. Router 2 is the head-end router in an SR-TE tunnel, and it is learning topology of the network from the PCE enabled on Router 1.
  D. Router 2 is the head-end router in an SR-TE tunnel, and it is learning topology of the network from the PCE enabled on Router 1.

• Question 227:

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

• Question 228:

  Refer to the exhibit.

  

  A network engineer is investigating a report of packet drops in an application running on a server connected to PE2. The engineer determined that:

  1.

  The OSPF adjacency in area 0 is up, and it is learning the loopback addresses of all routers in area 0.

  2.

  Traffic from users connected to PE1 to the application is also passing normally.

  3.

  Packets from PE2 back to PE1 are being dropped.

  Which action resolves the issue?

  A. RR2(config)# router bgp 100 RR2(config-router)# redistribute ospf 100
  B. RR1(config)# router bgp 100 RR1(config-router)# redistribute ospf 100
  C. RR1(config)# router bgp 100 RR1(config-router)# neighbor 10.10.30.1 send-label
  D. RR2(config)# router bgp 100 RR2(config-router)# no neighbor 10.10.20.1 send-label
  C. RR1(config)# router bgp 100 RR1(config-router)# neighbor 10.10.30.1 send-label

• Question 229:

  Refer to the exhibit.

  

  Users connected to an application on 1.1.1.1 via routers CE1 and CE2 are complaining of frequent disconnections. While troubleshooting the issue, a network engineer with an employee ID: 1234:56:789 determined that the application itself is working normally, but the link connected to the 1.1.1.1 application is flapping. The users on CE1 and CE2 are accessing applications on 2.2.2.2 without difficulty. Which action resolves the issue?

  A. Enable passive interface on the router R3 Loopback1 interface.
  B. Disable split horizon on router R2.
  C. Enable route dampening on routers R1 and R2.
  D. Redistribute CE1 routes on router R2.
  C. Enable route dampening on routers R1 and R2.

• Question 230:

  A network engineer recently deployed a wireless network for users at a new office to join video conferences wirelessly. The existing network consists of routers that are configured for EIGRP and BGP, which are located at several data centers in different physical locations. The engineer configured PIM-SSM within a single domain from a single source. However, during the testing phase, the video conference failed to work for any of the users. The IPs are reachable and firewalls in the network are configured correctly to allow the traffic. Which action resolves the issue?

  A. Configure PIM sparse mode to replace PIM-SSM.
  B. Configure PIM dense mode to replace PIM-SSM.
  C. Configure the devices to send join messages toward a multicast SPT.
  D. Configure PIM dense mode with multidomain multicast.
  C. Configure the devices to send join messages toward a multicast SPT.
