• Question 274:

  Refer to the exhibit.

  

  

  A network engineer is investigating a report of packet drops between the branch site and the central site.

  1.

  The two sites are connected via OSPF and RSVP-TE tunnels.

  2.

  Traffic from the central site to the branch site is passing normally.

  3.

  Technicians at both sites successfully ping the loopback IP addresses on routers R1 and R2.

  Which configuration corrects the packet-drop problem?

  A. R2(Config)# interface Tunnel333 R2(Config-if)# tunnel mpls traffic-eng bandwidth 33000
  B. R1(Config)# interface Tunnel222 R1(Config-if)# tunnel mpls traffic-eng bandwidth 33000
  C. R1(Config)# interface Ge0/0 R1(Config-if)# ip rsvp bandwidth 33000 3300
  D. R2(Config)# interface Ge0/0 R2(Config-if)# ip rsvp bandwidth 33000 3300
  C. R1(Config)# interface Ge0/0 R1(Config-if)# ip rsvp bandwidth 33000 3300

• Question 275:

  Refer to the exhibit.

  

  MPLS traffic from 192.168.4.0/24 to 192.168.5.0/24 is failing to pass over the link from R4 to R2. The engineer verified that:

  1.

  Cisco Express Forwarding Is enabled on all routers.

  2.

  All routers reach all networks via OSPF.

  3.

  MPLS traffic from 192.168.1.0/24 to 192.168.3.0/24 is passing normally over the link from R1 to R2. Which action resolves the issue?

  A. On router R4, remove the mpls ip command on the s/O/O/2 interface.
  B. On router R2, configure the mpls ip command on the SIO/O/4 interface.
  C. On router R4, configure the mpls label protocol Idp command on all serial interfaces.
  D. On router R2, configure the mpls label protocol Idp command on the interface.
  B. On router R2, configure the mpls ip command on the SIO/O/4 interface.

• Question 276:

  Which two differences should be considered when deciding whether to implement routing policies or route maps? (Choose two.)

  A. Sequences are added after implementing a route map, but routing policies must be reconfigured when change is needed
  B. Route maps are supported in Cisco IOS Software and routing policies are supported in Cisco IOS XR Software
  C. Route maps are implemented using hierarchical policies, but routing policies must be implemented sequentially
  D. Route maps require an explicit deny at the end of the sequence, but routing policies have an implicit deny at the end of the program
  E. Route policies require sequence numbers, but route maps are implemented without sequencing
  A. Sequences are added after implementing a route map, but routing policies must be reconfigured when change is needed
  B. Route maps are supported in Cisco IOS Software and routing policies are supported in Cisco IOS XR Software

• Question 277:

  Refer to the exhibits.

  

  A network operator is troubleshooting packet loss seen from the R1 loopback interface to the R2 loopback interface over the core network. The operator is attempting to identify the next leg in the path from PE1. Which interface and label path should the operator investigate next?

  A. PE1 - Gi0/0/0/3 - forwarding label 24002
  B. PE1 - Gi0/0/0/2 - forwarding label 24002
  C. PE1 - Gi0/0/0/3 - forwarding label 24001
  D. PE1 - Gi0/0/0/2 - forwarding label 24001
  C. PE1 - Gi0/0/0/3 - forwarding label 24001

• Question 278:

  Which two methods represent IPv6 tunneling implementations? (Choose two.)

  A. IPv6 over GRE tunneling
  B. manually configured tunnels
  C. automatic tunnels
  D. 6to4 tunneling
  E. IPv6 over an IPv4 tunnel over MPLS
  B. manually configured tunnels
  C. automatic tunnels

• Question 279:

  Refer to the exhibit.

  

  A network operator is working to filter routes from being advertised that are covered under an aggregate announcement. The receiving router of the aggregate announcement block is still getting some of the more specific routes plus the

  aggregate.

  Which configuration change ensures that only the aggregate is announced now and in the future if other networks are to be added?

  A. Configure the summary-only keyword on the aggregate command
  B. Set each specific route in the AGGRO policy to drop instead of suppress-route
  C. Filter the routes on the receiving router
  D. Set each specific route in the AGGRO policy to remove instead of suppress-route
  A. Configure the summary-only keyword on the aggregate command
