• Question 274:

  REP has been deployed in a segment. A network operations engineer notices that a segment port does not become operational. What is the root cause of this issue?

  A. A neighbor is using a different port ID
  B. A local port is in alternate port state
  C. A neighbor port is in blocked state
  D. More than one neighbor has the same segment ID
  D. More than one neighbor has the same segment ID

• Question 275:

  A. On PE1,apply nexto-hop-self on both PE2 and PE3 neighbors configuration
  B. On the CE, apply bgp add-path on both PE1 and PE2 neighbors configuration
  C. On PE1, apply route-reflect-client on both PE2 and PE3 neighbors configuration
  D. On PE2, apply bgp advertise-best-external on the PE3 neighbor configuration
  D. On PE2, apply bgp advertise-best-external on the PE3 neighbor configuration

• Question 276:

  Which command will display the MPLS label binding for IP prefix 1.1.1.0 on the router?

  A. All of the above.
  B. show tag-switching tdp binding 1.1.1.0/24
  C. show tag-switching tdp bindings neighbor 1.1.1.0
  D. A and B both will show the binding.
  E. show tag-switching interface e0/0
  B. show tag-switching tdp binding 1.1.1.0/24

• Question 277:

  Which option is the benefit of per-link LFA over per-prefix LFA?

  A. It has a greater applicability
  B. It provides greater protection coverage
  C. It is simpler
  D. It enables better bandwidth utilization
  C. It is simpler

• Question 278:

  A network engineer observes increasing output drops on the serial interface. Which two solutions can be implemented to minimize these drops? (Choose two.)

  A. Increase the MTU size on the link.
  B. Replace the serial cable between the connecting devices.
  C. Turn on fast switching.
  D. Increase the output hold queue size.
  E. Implement priority queuing on slower serial links by configuring priority lists.
  D. Increase the output hold queue size.
  E. Implement priority queuing on slower serial links by configuring priority lists.

• Question 279:

  Which are three advantages of PPPoA implementation? (Choose three)

  A. NAP and NSP provide secure access to corporate gateways without managing end-to- end PVCs. NAP and NSP use Layer 3 routing, Layer 2 Forwarding, or Layer 2 Tunneling Protocol tunnels. Hence, they can scale their business models for selling wholesale service.
  B. The NSP can oversubscribe by deploying idle and session timeouts using an industry standard RADIUS server for each subscriber.
  C. Only a single session per CPE on one virtual channel (VC). The username and password are configured on the CPE, so all users behind the CPE for that particular VC can access only one set of services. Users cannot select different sets of services, although using multiple VCs and establishing different PPP session on different VCs is possible.
  D. If a single IP address is provided to the CPE, and NAT or PAT is implemented, certain pplications such as IPTV, which embed IP information in the payload, well not work. Additionally, if an IP subnet feature is used, an IP address also has to be reserved for the CPE.
  E. PPPoA can use the features on the Cisco Service Selection Gateway (SSG)

• Question 280:

  Which action does a switch running OpenFlow take when it receives a packet that does not match its flow entry?

  A. Reject the packet.
  B. Forward the packet to the controller.
  C. Drop the packet.
  D. Transfer the packet.
  E. Flood the packet.
  B. Forward the packet to the controller.
