• Question 672:

  In which two ways is IPv4 and IPv6 traffic handled in a network design that uses QoS deployment options? (Choose two.)

  A. IPv6 and IPv4 traffic is treated in the same way by using a single QoS policy that classifies and matches on both protocols.

  B. IPv6 traffic is treated differently than IPv4 by using the flow-label field, which is built into the IPv6 packet header.

  C. IPv6 traffic does not require QoS because it uses to the flow-label field, which classifies and matches on the IPv6 protocol.

  D. IPv6 traffic is treated differently than IPv4 by using two different QoS policies.

  E. IPv6 traffic is treated differently than IPv4 because it uses only the DSCP value and not the IP precedence.

  Correct Answer: AD

• Question 673:

  You have been hired by a startup company to provide optical services using MPLS-TP. Which three options describe reasons to use the MPLS-TP standard in your design? (Choose three.)

  A. MPLS-TP is a newer packet transport technology that replaces SONET/SDH.

  B. MPLS-TP includes extensions to native MPLS OAM for fault detection, monitoring, and propagation.

  C. MPLS-TP requires a routing protocol.

  D. MPLS-TP uses an IANA assigned label 13 for OAM.

  E. MPLS-TP uses Ethernet Y.1731 OAM.

  Correct Answer: ABD

• Question 674:

  Refer to the exhibit.

  

  Which routes in this network will be installed in the routing table at router E?

  A. the OSPF route

  B. the EIGRP route

  C. the OSPF and EIGRP routes

  D. neither the OSPF nor the EIGRP route

  Correct Answer: C

• Question 675:

  You are the lead IP/MPLS network designer of a service provider called XYZ. You are leading a design discussion regarding IPv6 implementation in the XYZ MPLS network, using MPLS 6PE/6VPE techniques. Currently, XYZ provides IPv4 multicast services over an MPLS network by using MVPN, and would like to provide parallel IPv6 multicast services. Which three multicast solutions should be enabled? (Choose three.)

  A. native IPv6, only for multicast services

  B. MPLS 6PE/6VPE, because it provides IPv6 multicast support by default

  C. an overlay model using Layer 2 MPLS tunnels

  D. PIM-DM to enable IPv6 multicast in conjunction with MPLS 6PE/6VPE

  E. MVPN for IPv6 multicast service

  Correct Answer: ACE

• Question 676:

  A service provider wants to offer a service that allows customers to span VLANs across multiple campuses.

  Which configuration will allow this service provider to achieve its desired result with a minimal impact on the scalability of PE routers?

  A. RFC 2547-based service, with L2TPv3 between PE and CE

  B. RFC 2547-based service, with MPLS/LDP between PE and CE (in other words, CsC)

  C. VPWS service, with 802.1Q between PE and CE

  D. VPWS service, with QinQ between PE and CE

  Correct Answer: D

• Question 677:

  An IBGP mesh design is being scoped, and in the discussions, one of the design engineers proposes the use of route reflectors. Which limitation is valid when using route reflectors in this design?

  A. The configuration complexity on the routers will be increased.

  B. Route reflectors will limit the total number of routes in the topology.

  C. Multipath information is difficult to propagate in a route reflector topology.

  D. Route reflectors will cause an opportunity to create routing loops.

  Correct Answer: C

• Question 678:

  As part of the security protocol for your network design, you have designated that option 82 is enabled for DHCP snooping. When option 82 is enabled, which information will be added to the DHCP request?

  A. switch MAC address and VLAN, module, and port

  B. remote ID and circuit ID

  C. switch IP address and VLAN, module, and port

  D. switch MAC address and switch IP address

  Correct Answer: B

• Question 679:

  Refer to the exhibit.

  

  You are designing a spanning-tree network for a small campus. Which two of these options would result in a trouble-free spanning-tree network design? (Choose two.)

  A. Convert all ports to trunk ports, prune off the VLANs that you do not require, and minimize the number of blocking ports.

  B. Introduce Layer 3 VLANs (SVIs) and prune off the VLANs that you do not require.

  C. Convert all the ports to trunk and enable BackboneFast.

  D. Convert all the ports to trunk and enable UplinkFast between all the links.

  Correct Answer: AB

• Question 680:

  Refer to the exhibit.

  

  You are designing a loop-free hierarchical VPLS service. Which two design considerations should be implemented for the pseudowires between the N-PE and U-PE routers? (Choose two.)

  A. Disable split horizon toward the N-PE routers.

  B. Disable split horizon toward the U-PE router.

  C. Enable split horizon toward the U-PE router.

  D. Enable split horizon toward the N-PE routers.

  E. Disable MAC learning on the U-PE route.

  F. Disable MAC learning on the N-PE routers.

  Correct Answer: BD
