  F. limited VLAN-based VPLS traffic hashing

  Correct Answer: ABC

• Question 462:

  You are designing an Out of Band Cisco Network Admission Control, Layer 3 Real-IP Gateway deployment for a customer. Which VLAN must be trunked back to the Clean Access Server from the access switch?

  A. untrusted VLAN

  B. user VLAN

  C. management VLAN

  D. authentication VLAN

  Correct Answer: A

• Question 463:

  Which restriction prevents a designer from using a GDOI-based VPN to secure traffic that traverses the Internet?

  A. Enterprise host IP addresses are typically not routable.

  B. GDOI is less secure than traditional IPsec.

  C. Network address translation functions interfere with tunnel header preservation.

  D. The use of public addresses is not supported with GDOI.

  Correct Answer: C

• Question 464:

  Enterprises A and B agree to merge, but keep IGP and BGP independent of each other. They are served by a common ISP for their Internet connectivity. During the merge, A and B will provision a point-to-point link between the two networks. What is the simplest design option that will allow data to travel between A and B without passing through the ISP?

  A. configure OSPF and make OSPF routes more attractive than the same routes learned via EBGP from the ISP

  B. configure OSPF and make OSPF routes less attractive than the same routes learned via EBGP from the ISP

  C. configure EBGP between the two networks and block each other's routes from the ISP

  D. configure iBGP between the two networks and block each others route's from the ISP

  E. configure OSPF between the two networks and block each others route's from the ISP

  Correct Answer: C

• Question 465:

  What is the most effective way to improve BGP convergence in the event that a point-to- point link, over which an EBGP session is running, fails?

  A. reduce the keepalive timer to the minimum value allowed

  B. configure EBGP fast external fallover

  C. use BGP multihop

  D. enable BGP graceful restart

  Correct Answer: B

• Question 466:

  You are the lead network designer hired by Service Provider XYZ to deploy CoS functionality on the core MPLS network (P routers). The goal of the network design is to provide a complete CoS solution to all customers that purchase services such as dedicated Internet access, MPLS L3VPN, and L2VPN (pseudowire). Service

  Provider XYZ has these design requirements:

  - The network supports four service queues with equal treatment for delay, jitter, and packet loss.

  -Queues are numbered 0-3, where 0 is the default queue.

  -Three queues have one treatment.

  -

  One queue has either one or two treatments.

  If your design includes eight CoS queues on the Service Provider XYZ MPLS PE router ingress (CE facing)

  interface, how will customer traffic be classified as it enters the MLS P routers?

  A.

  The eight CoS queues in the MPLS P router are remapped to the eight CoS queues.

  B.

  Traffic is classified on the MPLS PE routers on core facing interface. The DSCP value is mapped into EXP field where multiple EXP settings (2+) will be assigned to a single queue throughout the MPLS P routers.

  C.

  Discard the traffic from the eight CoS queues that does not match the four CoS queues of the MPLS P routers.

  D.

  The 8 CoS queues in the MPLS P router are remapped to four 4 flow-label queues.

  Correct Answer: B

• Question 467:

  Refer to the exhibit.

  

  Which technology could be used in this design to provide link recovery and high traffic capacity?

  A. Rapid PVST

  B. MST

  C. PAgP

  D. Flex Links

  Correct Answer: C

• Question 468:

  You have been tasked to create a Layer 2 network design that uses vPC to provide resiliency and avoid loops. vPC removes Layer 2 loops while providing redundancy through which mechanism?

  A. dual-active detection

  B. address synchronization

  C. strict forwarding rules

  D. Bridge Assurance

  Correct Answer: C

• Question 469:

  You have been asked to design a wireless network solution that will implement context- aware services on an existing network that was initially deployed for data traffic only. Which two design principles would you follow to increase the location accuracy with the least possible impact on the current setup? (Choose two.)

  A. Use directional antennas to provide better cell separation.

  B. Add access points along the perimeter of the coverage area.

  C. Install additional APs in monitor mode where the cochannel interference would otherwise be affected.

  D. Increase the AP density to create an average interaccess point distance of less than 40 ft.

  E. Fine tune the access points radio configuration to have a higher average transmission power to achieve better coverage.

  Correct Answer: BC

• Question 470:

  When network summaries are created for access networks in a network design, how does it change the behavior of the Shortest Path First (SPF) running in a backbone area?

  A. There would be fewer incremental SPFs.

  B. There would be fewer partial SPFs.

  C. There would be fewer full SPFs.

  D. There would be no change with the SPFs.

  Correct Answer: B
