Exam A
QUESTION 1
A company plans to include Nonstop Forwarding and Bidirectional Forwarding Detection as a part of their network redundancy plan. In which two ways do NSF and BFD work together when different hardware platforms are compared? (Choose two.)
A. During supervisor engine or routing engine failover, the NSF feature will always ensure that the BFD at the peer router will not trigger a link down independent of the used hardware platform.
B. At some hardware platforms, BFD and NSF are not supported together. During supervisor engine or routing engine failover, the BFD at the peer router will trigger a link down.
C. To ensure that BFD at the peer router will not trigger a link down during NSF, the BFD packets must be processed fast enough, and, during supervisor engine or routing engine failover, by processing the BFD independent from the supervisor engine or routing engine.
D. Because BFD is always processed at the line cards (not at the supervisor engine or routing engine), a supervisor engine or routing engine failover will not affect the BFD peer router.
E. Because BFD is always processed at the supervisor engine or routing engine, a supervisor engine or routing engine failover will always trigger a link down at the peer router.
Correct Answer: BC
QUESTION 2

A service provider would like to use Ethernet OAM to detect end-to-end connectivity failures between SP-SW1 and SP-SW2. In which two of these ways can you design this solution? (Choose two.)
A. Enable Y.1731 Connectivity Fault Management on the SP switches.
B. E-LMI PDUs must be forwarded over VPLS.
C. Cisco Discovery Protocol PDUs must be forwarded over the VPLS.
D. Use upward maintenance endpoints on the SP switches.
E. Enable IEEE 802.1ag Connectivity Fault Management on the SP switches. “Pass Any Exam. Any Time.” – www.actualtests.com 2 Cisco 352-001 Exam
Correct Answer: DE
QUESTION 3
A network design shows two routers directly connected to an Ethernet switch using optical connections. There is an OSPF adjacency between the routers. In this design, which solution will ensure that interface down detection is reported as quickly as possible to the IGP?
A. optimized OSPF SPF timers
B. Bidirectional Forwarding Detection
C. automatic protection switching
D. optimized OSPF LSA timers
E. Ethernet OAM CFM monitoring
Correct Answer: B
QUESTION 4

A. LACP system priority and switch MAC address
B. LACP port priority and switch MAC address
C. LACP port priority and port number
D. LACP system priority and port number

You are designing a spanning-tree network for a small campus. Which two of these options would result in a trouble-free spanning-tree network design? (Choose two.)
A. Convert all ports to trunk ports, prune off the VLANs that you do not require, and minimize the number of blocking ports.
B. Introduce Layer 3 VLANs (SVIs) and prune off the VLANs that you do not require.
C. Convert all the ports to trunk and enable BackboneFast.
D. Convert all the ports to trunk and enable UplinkFast between all the links.
Correct Answer: AB
QUESTION 6
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?

B. UniDirectional Link Detection
C. UniDirectional Link Detection aggressive mode
D. root guard
Correct Answer: C QUESTION 7
A switched network is being designed to support a manufacturing factory. Due to cost constraints, fiber-based connectivity is not an option. Which design allows for a stable network when there is a risk of interference from the manufacturing hardware in use on the factory floor?
A. Design the network to include UDLD to detect unidirectional links and take them out of service.
B. Design the network to include EtherChannel bundles to prevent a single-link failure from taking down a switch interconnection point.
C. Design the network to include loop guard to prevent a loop in the switched network when a link has too much interference.
D. Design the network to include BackboneFast on all devices to accelerate failure convergence times.
Correct Answer: A QUESTION 8

A. Switch A
B. Switch B
C. Switch C
D. Switch D
Correct Answer: CD
QUESTION 9
A service provider has a Resilient Ethernet Protocol ring running as a metro backbone between its locations in one city. A customer wants to connect one site with one box redundant to the Resilient Ethernet Protocol ring at two different service provider locations. How can this be done without producing any Layer 2 loops within the network design?
