• Question 271:

  Refer to the exhibit.

  

  The R1 and R2 routers are running OSPF, LDP, and BGP. Why is the label for 1.1.1.1 prefix absent in the R2's MPLS forwarding table?

  A. IP MTU cannot accommodate labels.
  B. The MPLS tunnel is not enabled for the Fast Ethernet 0/0 interface.

  C. PIM sparse mode is not enabled on a participating multicast interface.

• Question 275:

  Which statement about MPLS TE Fast Reroute (FRR) link protection operation is not true?

  A. It requires a next-hop backup tunnel.
  B. The backup tunnel terminates on the same tail-end router as the primary tunnel.
  C. The point of local repair (PLR) swaps the label and pushes the backup label.
  D. The restoration time is expected to be under 50 ms.
  E. The backup tunnel can have associated bandwidth capacity
  B. The backup tunnel terminates on the same tail-end router as the primary tunnel.

  1.7. MPLS Traffic Engineering

  The backup tunnel terminates on the merge point (MP) where traffic rejoins the primary tunnel.

• Question 276:

  Which ITU publication defines the requirements for communicating data over an optical network?

  A. G.706
  B. G.707
  C. G.708
  D. G.709
  D. G.709

• Question 277:

  Which statement about implementing the Cisco IPv6 provider Edge Router over MPLS is true?

  A. 6PE feature is supported over tunnels other than RSVP-TE tunnels.
  B. Core MPLS routers are supporting IPv6 only.
  C. 6PE feature is not supported over tunnels other than RSVP-TE tunnels.
  D. Core MPLS routers are supporting IPv4 only.
  C. 6PE feature is not supported over tunnels other than RSVP-TE tunnels.

  ReferencE. http://www.cisco.com/en/US/docs/ios/ipv6/configuration/guide/ip6-over_mpls.pdf The following restrictions apply when implementing the IPv6 Provider Edge Router over MPLS (6PE) feature:

  Core MPLS routers are supporting MPLS and IPv4 only, so they cannot forward or create any IPv6 Internet Control Message Protocol (ICMP) messages. Load balancing ability is not provided by Cisco 6PE between an MPLS path and an

  IPv6 path. If both are available, the MPLS path is always preferred. Load balancing between two MPLS paths is possible. BGP multipath is not supported for Cisco 6PE routes. If two BGP peers advertise the same prefix with an equal cost,

  Cisco 6PE will use the last route to cross the MPLS core. 6PE feature is not supported over tunnels other than RSVP-TE tunnels.

• Question 278:

  DSCP value "101110" looks like which IP Precedence value to non-DiffServ compliant devices?

  A. IP Precedence 6
  B. IP Precedence 4
  C. IP Precedence 3
  D. IP Precedence 5
  E. IP Precedence 2
  F. IP Precedence 7
  D. IP Precedence 5

• Question 279:

  RFC 3270 describes Differentiated Services (Diff-Serv) over Multi-Protocol Label Switching (MPLS) networks.

  Which model alters Differentiated Services (Diff-Serv) code points set in different Differentiated Services (Diff-Serv) domain?

  A. None of the above will alter Differentiated Services (Diff-Serv) code points set in different Differentiated Services (Diff-Serv) domain.
  B. Uniform model
  C. Pipe Model
  D. Short Pipe
  B. Uniform model
