• Question 522:

  In Cisco IOS XR architecture, what is lightweight messaging?

  A. the communication with several thousand nodes that each run an instance of the kernel
  B. something that reliably multicasts data to various nodes, such as RPs and MSCs, using GSP as the underlying transport
  C. the mode fundamental level, responsible for warning when physical parameters fall outside of operational ranges and shutting down the hardware when parameters approach critical levels
  D. a form of messaging that Cisco designed to create a layer of abstraction between the application that inter process communicate with each other
  D. a form of messaging that Cisco designed to create a layer of abstraction between the application that inter process communicate with each other

• Question 523:

  

  Refer to the exhibit. Two customer sites are connected via an MPLS Layer 3 VPNv4 network. OSPF is used as a PE-CE routing protocol. EIGRP is used in the internal LAN that connects the CE02. CE01 cannot reach any host connected in this LAN. Which configuration must be applied to fix this issue?

  A. CE2# router ospf 65000 address-family ipv4 vrf VPN_A redistribute eigrp 65000 match internal external 1 external 2
  B. PE2# router bgp 100 address-family ipv4 vrf VPN_A redistribute eigrp 6500 vrf VPN_A
  C. PE2# router bgp 100 address-family ipv4 vrf VPN_A redistribute connected
  D. PE2# router bgp 100 address-family ipv4 vrf VPN_A redistribute ospf 100 vrf VPN_A match internal external 1 external 2
  A. CE2# router ospf 65000 address-family ipv4 vrf VPN_A redistribute eigrp 65000 match internal external 1 external 2

  B. DS-TE
  C. PBTS
  D. IP FBR
  A. CBTS

• Question 525:

  Which constraint is a pre-requisite of implementing configuration replace and configuration rollback?

  B. The directory command must be configured to specify the location and filename prefix for the configuration files.
  C. The path command must be configured to specify the name of the configuration files.
  D. The configuration archive must be configured before performing Configuration Rollback Confirmed Change.
  A. The device must have available free memory larger than the combined size of the two configuration files.

  A. Traffic entering on PE27 marked with an EXP value of 1 is sent via MPLS TE Tunnel 2.
  B. The outgoing interface towards the tail-end router is MPLS TE Tunnel 100.
  C. Packets with an EXP value of 3 is assigned to MPLS TE Tunnel 1 because of an unmatched EXP.
  D. The EXP bundle master tunnel is not functional because of a signaling failure.
  E. Packets marked with an EXP value of 3 are switched via MPLS TE Tunnel 4.
  F. Packets with unmapped EXP values are forwarded directly via MPLS TE Tunnel 100.
  G. Packets marked with an EXP value of 5 are load balanced across MPLS TE Tunnel 1 and MPLS TE Tunnel 4.

• Question 528:

  A Layer 3 VPN customer opened a case that reports connectivity loss with remote sites. An operations engineer realized this connectivity loss happened after the LDP label filtering was applied. What is the root cause of this issue?

  B. Labels were not allocated for the PE loopbacks
  C. Labels were not allocated for the CE loopback and physical interfaces
  D. Labels were not allocated for the P loopbacks
  E. Labels were not allocated for the PE, P , and RR loopbacks
  F. Labels were not allocated for the P and PE physical interfaces
  E. Labels were not allocated for the PE, P , and RR loopbacks

• Question 529:
