Cisco Cisco Certifications 352-001 Questions & Answers

• Question 431:

  You are using iSCSI to transfer files between a 10 Gigabit Ethernet storage system and a 1 Gigabit Ethernet server. The performance is only approximately 700 Mb/s and output drops are occurring on the server switch port. Which action will improve performance in a cost- effective manner?

  A. Use a WRED random drop policy.

  B. Increase the queue to at least 1 GB.

  C. Enable the TCP Nagle algorithm on the receiver.

  D. Change the protocol to CIFS.

  Correct Answer: A

• Question 432:

  A company is planning to deploy high-availability cluster support for their servers in a collapsed core data center design. Which issue should be a concern with this design?

  A. NIC teaming

  B. MAC address aging

  C. Layer 3 domain sizing

  D. Layer 2 domain sizing

  Correct Answer: D

• Question 433:

  Which option is a benefit of using N-Port Virtualization?

  A. reduces the amount of domain IDs that are used in the fabric

  B. does not need to create zoning

  C. reduces latency when using local switching on Fibre Channel ports

  D. allows trunking to the upstream switch

  E. does not need to configure the upstream switches

  Correct Answer: A

• Question 434:

  Refer to the exhibit.

  

  In the DWDM network, a ring topology carries multiple services between two sites. Which option describes the employed protection design?

  A. Y-cable protection

  B. Splitter protection

  C. Client protection

  D. UDLD

  E. FEC protection

  Correct Answer: C

• Question 435:

  A green data center is being deployed and a design requirement is to be able to readily scale server virtualization. Which IETF standard technology can provide this requirement?

  A. Transparent Interconnection of Lots of Links

  B. fabric path

  C. data center bridging

  D. unified fabric

  Correct Answer: A

• Question 436:

  Which mechanism provides a Layer 2 fault isolation between data centers?

  A. TRILL

  B. LISP

  C. advanced VPLS

  D. OTV

  E. fabric path

  Correct Answer: D

• Question 437:

  In a PIM sparse mode network, how is the flow of multicast traffic restored when a link fails along a branch of a multicast distribution tree?

  A. The downstream receivers notice the loss of the multicast flow and resend PIM join messages to reestablish the tree.

  B. The downstream receivers notice the loss of the multicast flow and resend IGMP Membership Reports to reestablish the tree.

  C. The traffic reverts to the shared tree while the downstream router recalculates the RPF interface and sends a new PIM join message to the RP.

  D. The router downstream of the break recalculates the RPF interface when it notices a change in the unicast routing table and immediately sends a new PIM join message out from the new RPF.

  Correct Answer: D

• Question 438:

  You are designing a large Frame Relay WAN for a customer. The routing protocol is OSPF. What is the effect on the routing table if the WAN interfaces are configured as point-to- multipoint?

  A. Only a route for the DR will be present in the routing table.

  B. Configuring point-to-multipoint has no effect on the routing table. The route that is configured with the area command will be seen in the routing table.

  C. Multipoint interfaces dynamically add the network of the connected interface.

  D. Multipoint interfaces dynamically add a /32 route for each neighbor in the WAN.

  Correct Answer: D

• Question 439:

  A client has approached you about deploying very fast IS-IS hello timers across an intercontinental high speed SONET link.

  What should you recommend?

  A. Fast hello timers are a good choice for this link because on long haul SONET links the reporting of LINE and PATH errors can take a long time.

  B. Fast hello timers are not a good choice for this link because the link is physically long and the propagation delay may cause IS-IS to believe the link has failed when it has not.

  C. Fast hello timers are a good choice for this link because the length of the link indicates there will be at least one SONET amplifier that disables PATH alarms on the circuit.

  D. Fast hello timers are not a good choice for this link because SONET links provide link- down notification much faster than IS-IS could detect a circuit failure by means of hello processing.

  Correct Answer: D

• Question 440:

  There is an MPLS-enabled link constantly flapping on an MPLS VPN network. Given that the network runs OSPF as the IGP protocol, which design mechanism will stabilize the network and avoid constant reconvergences?

  A. BFD

  B. IP Event Dampening

  C. OSPF fast hellos

  D. partial SPF

  Correct Answer: B
