• Question 491:

  Which statement is true about Cisco IOS XR commit command?

• Question 492:

  Refer to the exhibit.

  

  An MPLS-based service provider wants to deploy QoS over its backbone. Original customer QoS information must be preserved when the packet leaves the MPLS network. In addition, the egress LSR must forward packets according to the LSP Diff-Service information, as depicted in the topology. Which QoS model satisfies these requirements?

  A. uniform model
  B. pipe model
  C. short-pipe model
  D. IntServ model
  B. pipe model

  A. neighbor allowas-in

• Question 496:

  A service provider is in the process of providing Layer 2 and Layer 3 VPN services through a MPLS LDP-enabled backbone.

  A. CE loopbacks only that are used as BGP next hop
  B. PE loopbacks that are used as BGP next hop
  C. RR, P , and PE loopbacks that are used as BGP next hop
  D. all /32 prefixes advertised in the IGP
  C. RR, P , and PE loopbacks that are used as BGP next hop

• Question 497:

  Refer to the exhibit.

  

  The link payload rate is subdivided into multiple fixed-rate channels. In addition, the data rate of a single cell or packet flow is limited by the bandwidth of an individual channel. If the link is an OC-48, into how many channels can the link be subdivided?
