Cisco Cisco Certifications 352-001 Questions & Answers

• Question 561:

  An enterprise network manager has decided to dual-home two service providers for Internet connectivity. In order to provide optimal outbound routing, the full Internet routing table will be accepted from each provider.

  The enterprise has obtained address space and an AS to use in connecting to the Internet.

  What is the simplest mechanism the network manager can use to prevent it from becoming a transit between the two service providers?

  A. Build a route filter that only allows the specific networks the enterprise owns to be advertised to each of the service providers.

  B. Build a traffic filter that only allows traffic originating from the specific networks the enterprise owns to be forwarded towards the service providers.

  C. Build a route filter that only allows networks with an empty AS path to be advertised to each of the service providers.

  D. Build a route filter that only allows networks which are tagged with the LOCAL community to be advertised to each of the service providers.

  Correct Answer: C

• Question 562:

  After the recent implementation of a new design that incorporated GRE tunnels into the network, the network operations staff is seeing the following syslog message in multiple routers on the network - %TUN-5-RECURDOWN: Tunnel0 temporarily disabled due to recursive routing. From a design perspective, what was not taken into account prior to implementing the solution?

  A. The neighboring routers cannot respond within the specified hold time.

  B. The interface on the router that is the source of the tunnel is down.

  C. The interface on the neighboring router that is the source of the tunnel is down.

  D. The router is learning the route to the tunnel destination address using the tunnel interface.

  E. The tunnel interface on the router is not receiving any keepalives within the specified hold time.

  Correct Answer: D

• Question 563:

  Acme Corporation indicates that their network design must support the ability to scale to support a high number of remote sites. Which IGP is considered to scale better for a hub-and-spoke topology?

  A. BGP

  B. OSPF

  C. IS-IS

  D. EIGRP

  Correct Answer: D

• Question 564:

  In a network design using carrier Ethernet, which three mechanisms can be used to improve Layer 2 down detection and thereby reduce routing convergence time? (Choose three.)

  A. BFD

  B. Ethernet port debounce timers

  C. link-state tracking

  D. object tracking

  E. fast IGP hello

  Correct Answer: ADE

• Question 565:

  What is the most efficient method of implementing IP multicast in a network without using RPs?

  A. Implement PIM dense mode multicast to eliminate the need for RPs.

  B. Implement source-specific multicast and utilize the functionality of IGMPv2 to replace the RPs.

  C. Implement source-specific multicast and utilize the functionality of IGMPv3 to replace the RPs.

  D. RPs can't be eliminated; they're mandatory in multicast networks.

  Correct Answer: C

• Question 566:

  In which two ways is a network design improved by the inclusion of IP Event Dampening? (Choose two.)

  A. reduces processing load

  B. provides sub-second convergence

  C. improves network stability

  D. prevents routing loops

  E. quickly detects network failures

  Correct Answer: AC

• Question 567:

  Which mechanism prevents switched traffic from traversing suboptimal paths on the network?

  A. PortFast

  B. UDLD

  C. root guard

  D. Bridge Assurance

  E. BPDU Filter

  Correct Answer: C

• Question 568:

  Refer to the exhibit.

  

  You are designing a Layer 2 VPN for a large financial company. Currently, 90% of traffic from the company's remote branches comes to HQ. The company has hubs and old switches at remotes that do not have dot1q capability. However, it does not have the budget to invest in new equipment at the remote branches. In addition to converting the remote branches to Layer 2 VPN, the company wants to connect all the branches to the HQ site, to ensure that the branches have access to dot1q capability. How can this customer's requirements be met, or if they cannot, why not?

  A. They cannot be met, because an intelligent switch is required at the remote branches to enable EoMPLS from site to site.

  B. They can be met, but require Ethernet to dot1q interworking between the PEs.

  C. They cannot be met, because EoMPLS in port mode requires VPLS.

  D. They can be met, but EoMPLS in port mode requires VPWS.

  Correct Answer: B

• Question 569:

  A network designer is redesigning an enterprise campus network to ensure that Ethernet switches proactively attempt to reconnect after a fiber cut. In the design, they will have to address areas where fiber cuts exist on campus from past troubleshooting, where a single fiber is disconnected in the fiber pair, leading to looping.

  Which feature could be implemented in the design to allow the Spanning Tree Protocol on the switches to be protected?

  A. loop guard

  B. UniDirectional Link Detection

  C. UniDirectional Link Detection aggressive mode

  D. root guard

  Correct Answer: C

• Question 570:

  Which of these is an advantage of creating an in-band rather than an out-of-band management network?

  A. protection of management traffic

  B. lower equipment costs

  C. separate transport equipment

  D. protection of production traffic

  Correct Answer: B
