Cisco Cisco Certifications 352-001 Questions & Answers

• Question 491:

  Your company's external routers BGP peer with multiple service providers and external organizations. In all cases, the external routers are peered with their BGP neighbors via directly-connected interfaces.

  How does GTSM provide additional security for your BGP speakers?

  A. GTSM prevents the processing of BGP packets from devices that are not on the directly- connected interfaces.

  B. GTSM prevents the formation of BGP adjacencies from unauthorized devices.

  C. GTSM ensures that all BGP routing updates have been verified for secure origination.

  D. GTSM replaces the TCP 3-way handshake between BGP speakers on directly connected interfaces.

  E. GTSM prevents random TCP resets from being injected into the BGP data stream.

  Correct Answer: A

• Question 492:

  Correct Answer: B

• Question 494:

  Which of these statements accurately describes MPLS-based L3VPN service?

  A. It allows for transparent routing across the service provider.

  B. It offloads routing between sites to the service provider.

  C. It is independent of the routed protocol.

  D. It improves routing protocols and network convergence.

  Correct Answer: B

• Question 495:

  Refer to the exhibit.

  

  In this network, R1 is redistributing 10.1.5.0/24 into Area 1. Which LSA containing 10.1.5.0/24 will R6 have in its database?

  A. R6 will have an NSSA external (type 7) LSA in its local database for 10.1.5.0/24.

  B. R6 will have an external (type 5) LSA for 10.1.5.0/24 in its local database.

  C. R6 will have a border router (type 4) LSA in its local database for 10.1.5.0/24.

  D. R6 will not have any LSAs containing 10.1.5.0/24.

  Correct Answer: D

• Question 496:

  In a large enterprise network with multiple data centers and thousands of access devices, OSPF is becoming unstable due to link flapping. The current design has the access devices multihomed to large aggregation routers at each of the data centers. How would you redesign the network to improve stability?

  A. Add a layer of regional Layer 3 aggregation devices, but leave the ABR function on the data center aggregation routers.

  B. Add a layer of regional Layer 2 aggregation devices, but leave the ABR function on the data center aggregation routers.

  C. Add a layer of regional Layer 3 aggregation devices and move the ABR function to the regional aggregation device.

  D. Add a layer of regional Layer 2 aggregation devices and move the ABR function to the regional aggregation device.

  Correct Answer: C

• Question 497:

  A. IPv6 is transparent on Layer 2 switches, so there is no need to make any changes to the Layer 2 switches.

  B. If IPv6 anycast deployment is planned, then make sure that Layer 2 switches support ICMPv6 snooping at Layer 2 switches.

  C. If IPv6 anycast deployment is planned, then make sure that Layer 2 switches support DHCPv6 snooping at Layer 2 switches.

  D. If IPv6 multicast deployment is planned, then make sure that Layer 2 switches support MLD snooping at Layer 2 switches.

  E. If IPv6 anycast deployment is planned, then make sure that Layer 2 switches support ND snooping at Layer 2 switches.

  Correct Answer: AD

• Question 498:

  What are two functions of an NSSA in an OSPF network design? (Choose two.)

  A. It overcomes issues with suboptimal routing when there are multiple exit points from the area.

  B. It allows ASBRs to inject external routing information into the area.

  C. An ASBR advertises Type 7 LSAs into the area.

  D. An ABR advertises Type 7 LSAs into the area.

  E. It uses opaque LSAs.

  Correct Answer: BC

• Question 499:

  Tesla Radio GmbH is going to build a new research lab network based on a set of switches that would connect to their existing enterprise network. They are considering a design that would guarantee loop-free behavior within the set of switches. The design would also allow the group of switches to seem like a single switch to the enterprise network, because it is owned by a separate administrative group. Which Spanning Tree Protocol should be used to support the design requirements?

  A. IEEE 802.1w

  B. IEEE 802.1D

  C. IEEE 802.1s

  D. IEEE 802.1p

  Correct Answer: C

• Question 500:

  As part of a new network design, you are helping the Network Management Team to develop a proactive report to identify places in the network where problems may happen. The network management tool can poll the network devices only via SNMP GET operations. Which two threshold-crossing metrics should you include in this report? (Choose two.)

  A. packet loss

  B. CPU utilization

  C. heat dissipation

  D. IP reachability

  E. energy consumption

  F. link bandwidth utilization

  Correct Answer: BF
