Cisco Cisco Certifications 352-001 Questions & Answers

• Question 621:

  AS100 and AS200 each have two peering points in different parts of their network. AS100 would like to use one of the links and keep the other link as backup. What should be changed for the design inside AS100 for prefixes received from AS200?

  A. MED

  B. weight

  C. AS-PATH

  D. local preference

  Correct Answer: D

• Question 622:

  In an MPLS-VPN environment, what is the effect of configuring an identical set of route targets for a particular VRF, but then configuring nonidentical route distinguisher across multiple PE devices?

  A. The routes will be correctly handled by the control plane, but there will be instances where routes take up twice as much memory.

  B. The routes will propagate to the remote PE, but the PE will never install them in its forwarding table.

  C. The routes will be rejected by the remote PE because they have a different RD than its routes.

  D. The routes will not even be sent to any remote PE with a different RD.

  Correct Answer: A

• Question 624:

  Refer to the exhibit.

  

  Your company designed a network to allow server VLANs in a data center to span all access switches. In the design, Layer 3 VLAN interfaces and HSRP are configured on the aggregation switches. In which three ways should the design of the STP domain be optimized for server and application performance? (Choose three.)

  A. Use loop guard on access ports.

  B. Use PortFast on access ports.

  C. Use root guard on access ports.

  D. Align Layer 2 and Layer 3 forwarding paths.

  E. Use BPDU Skew Detection on access ports.

  F. Explicitly determine root and backup root bridges.

  Correct Answer: BDF

• Question 625:

  Which tunneling mechanism provides confidentiality as well as tunneling capabilities?

  A. MPLS L3VPN

  B. IPsec ESP

  C. L2TPv3

  D. IPsec AH

  Correct Answer: B

• Question 626:

  You are designing a network to support data, voice and video. Which two main factors will you address to improve network convergence? (Choose two.)

  A. event propagation delay

  B. failure detection delay

  C. forwarding engine update delay

  D. routing table recalculation delay

  Correct Answer: BD

• Question 627:

  You are designing a network that will run EIGRP over a Metro Ethernet service that does not employ a link-loss technology. What will be the impact on convergence if there is a break in the end-to-end Layer 2 connectivity within the service provider network?

  A. The routers will immediately lose their adjacencies and converge.

  B. The routing protocol will not converge until the hold timers have expired.

  C. The switch ports connected to the router will go down and the routers will immediately converge.

  D. The VLAN on the switches will go inactive, the ports associated on the switch will go down, and the routers will immediately converge.

  Correct Answer: B

• Question 628:

  A data center provider has designed a network using these requirements:

  -Two data center sites are connected to the public Internet.

  -

  Both data centers are connected to different Internet providers.

  -

  Both data centers are also directly connected with a private connection for the

  internal traffic, and public Internet traffic can also be routed at this direct

  connection.

  - The data center provider has only one /19 public IP address block.

  Under normal conditions, Internet traffic should be routed directly to the data center where the services are located. When one Internet connection fails, the complete traffic for both data centers should be routed by using the remaining Internet connection. In which two ways can this routing be achieved? (Choose two.)

  A. The data center provider must have an additional public IP address block for this routing.

  B. One /20 block is used for the first data center and the second /20 block is used for the second data center. The /20 block from the local data center is sent out with a low BGP weight and the /20 block from the remote data center is sent out with a higher BGP weight at both sites.

  C. One /20 block is used for the first data center and the second /20 block is used for the second data center. The /20 block from the local data center is sent out without path prepending and the /20 block from the remote data center is sent out with path prepending at both sites.

  D. One /20 block is used for the first data center and the second /20 block is used for the second data center. Each /20 block is only sent out locally. The /19 block is sent out at both Internet connections for the backup case to reroute the traffic through the remaining Internet connection.

  E. One /20 block is used for the first data center and the second /20 block is used for the second data center. The /20 block from the local data center is sent out with a low BGP local preference and the /20 block from the remote data center is sent out with a higher BGP local preference at both sites.

  F. BGP will always load-balance the traffic to both data center sites.

  Correct Answer: CD

• Question 629:

  You are designing a solution to eliminate the risk of high CPU utilization on a core network composed of CRS-1 devices. Which option would eliminate the risk of high CPU utilization across the network?

  A. Use Local Packet Transport Services (LPTS) to manage hardware SNMP flow rate.

  B. Use the in-band control plane policy feature to reduce the SNMP flow rate.

  C. Use the control plane policy feature and reduce SNMP flow rate.

  D. Use control-plane management-plane in-band and reduce the SNMP flow rate.

  E. Use the control-plane management-plane out-of-band feature to reduce the SNMP flow rate.

  Correct Answer: A

• Question 630:

  Your enterprise customer has asked where they should deploy flow monitoring in their network to monitor traffic between branch offices. What is your design recommendation?

  A. at the edge of the network so that user traffic will be seen

  B. at the central site, because all traffic from the remotes will be seen there.

  C. in the core, because all traffic will be seen there

  D. in the data center, because all user traffic will be seen there

  Correct Answer: B
