• Question 551:

  Which two OSPF design considerations should you implement to support the eventual growth of a network, so that CPU and memory are unaffected by the size and complexity of the link-state database in a large service provider network? (Choose two.)

  A. Turn on route dampening.

  B. Create network summaries.

  C. Turn on the Incremental SPF feature.

  D. Add more memory.

  F. Add redundancy between critical locations.

  Correct Answer: CE

• Question 552:

  Senior management wants you to evaluate the risks to your network of offering VPWS, VPLS, GRE, or other tunneling services to your fiber-connected client base. Clients indicate that they prefer to use Layer 2 switches as CEs. Which two tunneling services expose your network to minimal risk and meet the clients' needs, including separation between providers and customer networks? (Choose two.)

  A. VPWS

  B. 802.1Q

  C. GRE

  D. VPLS

  E. QinQ

  Correct Answer: AE

• Question 553:

  Which of these is a reason to carry routes that originate outside your network in an EGP, such as BGP, rather than in your IGP, such as OSPF, EIGRP, or IS-IS?

  A. to provide better control over the distribution of the default route inside your network

  B. to prevent failures outside your network from impacting your internal network operation

  C. to provide faster convergence to destinations outside your network

  D. to provide a growth path for the core of your network

  Correct Answer: B

• Question 554:

  Your company experienced a number of network incidents that had a significant impact on business operations.

  Because a root cause cannot be identified, your CTO asks you to help the network management team implement the FCAPS framework. On which two areas would you provide guidance to the network management team? (Choose two.)

  A. change management

  B. accounting management

  C. service level management

  D. fault management

  Correct Answer: BD

• Question 555:

  What are two design advantages to using virtual port channel? (Choose two.)

  A. enhanced system availability through multiple systems

  B. reduced Spanning Tree Protocol convergence time

  C. loop management without use of Spanning Tree Protocol

  D. ability to use Spanning Tree Protocol blocked ports to forward traffic

  E. enhanced ability to recover from Spanning Tree Protocol changes

  Correct Answer: AC

• Question 556:

  What are two benefits of using BFD for failure detection in the design of a network? (Choose two.)

  A. BFD can provide failure detection in less than one second.

  B. BFD can be used as a generic and consistent failure detection mechanism for EIGRP, IS-IS, and OSPF.

  C. BFD eliminates router protocol hello notification.

  D. BFD can be used for all types of network interfaces.

  E. BFD is independent of the network protocol.

  Correct Answer: AB

• Question 557:

  A many-to-many enterprise messaging application is using multicast as a transport mechanism. As part of the network design for this application, which multicast address should be used, according to best practices outlined in RFC 2365?

  A. 224.0.0.60

  B. 232.192.0.60

  C. 239.128.0.60

  D. 239.193.0.60

  Correct Answer: D

• Question 558:

  Which two resources are propagated by the headend router for constrained based path computation with MPLS Traffic Engineering? (Choose two.)

  A. average link utilization

  B. average input queue depth

  C. link bandwidth

  D. link affinity

  E. link delay

  F. link jitter

  Correct Answer: CD

• Question 559:

  A customer is using a service provider to provide a WAN backbone for a 30-site network. In establishing the network, the customer must work within these constraints:

  The customer has a self-managed MPLS backbone.

  The VPLS WAN backbone of the service provider does not support PIM snooping.

  Multicast VPN must be used for multicast support inside some VRFs.

  What can the customer do so that multicast traffic is NOT flooded to all sites?

  A. Configure static GRE tunnels and run the MPLS and multicast VPN inside these GRE tunnels.

  B. Use Label Switched Multicast for the multicast transport.

  C. Use PIM-SSM as the multicast routing protocol with IETF Rosen Draft multicast VPN.

  D. Configure a static mapping between multicast addresses and MAC addresses.

  E. Use GET VPN to encrypt the multicast packets inside the WAN.

  Correct Answer: A

• Question 560:

  Refer to the exhibit.

  

  How would you redesign the network to improve availability of the routers 1A and 1B at the core site?

  A. Enable Graceful Restart Helper for OSPF

  B. Use link bundles over multiple slots

  C. Use APS Ethernet circuits and redundant interfaces

  D. Create a multichassis system with the two routers

  Correct Answer: D
