• Question 312:

  What is a characteristic of MVPN?

  A. It bypasses the use of MPLS in the service provider core and transmits packets using IP only.
  B. It uses pseudowires to route unicast and broadcast traffic over either a service provider MPLS or IP core.
  C. It allows VRF traffic to use the service provider MPLS VPN to route multicast traffic.
  D. It creates GRE tunnels to route multicast traffic over a service provider IP core.
  C. It allows VRF traffic to use the service provider MPLS VPN to route multicast traffic.

• Question 313:

  Refer to the exhibit.

  

  Which statement describes the effect of this configuration?

  A. It matches HTTP traffic for use in a policy map.
  B. It applies a service policy to all interfaces remarking HTTP traffic.
  C. It creates an ACL named WEB that filters HTTP traffic.
  D. It modifies the default policy map to allow all HTTP traffic through the router.
  A. It matches HTTP traffic for use in a policy map.

  ---

  Explanation

  The configuration creates a class map named WEB which is used to match HTTP traffic. This class map can then be referenced in a policy map to define specific actions for traffic that matches the criteria, such as applying QoS policies or traffic shaping.

  This concept is covered in the Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) course, where class maps and policy maps are discussed in the context of traffic classification and policy enforcement.

• Question 314:

  An engineer is implementing MPLS OAM to monitor traffic within the MPLS domain. Which action must the engineer perform to prevent packets from being forwarded beyond the service provider domain when the LSP is down?

  A. Configure a private IP address as the destination address of the headend router of Cisco MPLS TE.
  B. Disable IP redirects only on outbound interfaces.
  C. Disable IP redirects on all ingress interfaces.
  D. Implement the destination address for the LSP echo request packet in the 127.x.y.z/8 network.
  D. Implement the destination address for the LSP echo request packet in the 127.x.y.z/8 network.

  ---

  Explanation

  The question is about MPLS OAM (Operations, Administration, and Maintenance) and preventing packets from leaking outside the provider domain when the LSP is down.

  In MPLS OAM, LSP ping/echo requests use special destination addresses. To make sure these packets stay within the provider's MPLS domain, the destination address must come from the 127.x.y.z/8 range, which ensures they are not forwarded beyond the provider network.

• Question 315:

  Refer to the exhibit.

  

  A network administrator implemented MPLS routing between routers R1, R2, R3, and R4. AToM is configured between R1 and R4 to allow Layer 2 traffic from hosts on RA1 and RA2. A targeted MPLS session is established between R1 and R4. Which additional action must the administrator take on all routers so that LDP synchronization occurs between connected LDP sessions?

  A. Disable the MPLS LDP IGP sync holddown.
  B. Configure OSPF or IS-IS as the routing protocol.
  C. Configure EIGRP as the routing protocol using stub areas only.
  D. Enable MPLS LDP sync delay timers.
  A. Disable the MPLS LDP IGP sync holddown.

• Question 316:

  Refer to the exhibit.

  

  A service provider engineer is configuring the connection between CE1 and CE2. AS 200 of the service provider and AS 100 of enterprise ABC should connect using BGP. The engineer already completed the configuration of VRF RT 100:10 of enterprise ABC.

  Which configuration must the engineer apply on PE1 to meet the requirement?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  B. Option B

• Question 317:

  Refer to the exhibit.

  

  The network engineer who manages ASN 65001 is troubleshooting suboptimal routing to the 198.18.15.0/24 prefix. According to the network requirements:

  1. Routing to IP destinations in the 198.18.15.0/25 block must be preferred via the EDGE-1 PE.

  2. Routing to IP destinations in the 198.18.15.128/25 block must be preferred via the EDGE-2 PE.

  3. More specific prefixes of the 198.18.15.0/24 block must not be advertised beyond the boundaries of ASN 64611.

  4. Routing to 198.18.15.0/24 must be redundant in case one of the uplinks on INT-R1 fails.

  Which configuration must the network engineer implement on INT-R1 to correct the suboptimal routing and fix the issue?

  A. configure terminalroute-policy ASN65001-SPECIFIC-OUTif destination in (198.18.15.0/25) thenset community (no-export, peeras:65001)doneendifif destination in (198.18.15.0/24) thenprepend as-path 65001 3doneendifdropend-policy!router bgp 65001neighbor 100.65.0.1address-family ipv4 unicastroute-policy ASN65001-SPECIFIC-OUT outend
