Cisco Cisco Certifications 352-001 Questions & Answers

• Question 251:

  This smart city has decided to deploy a converged network for video surveillance and applications for utility services. These new applications are delay-sensitive and require strict convergence times of less than 50 milliseconds. The network is expected to have up to 50 intermediate distribution frames per ring. Which protocol provides less than 50 milliseconds convergence time?

  A. RSTP

  B. Ethernet Ring Protection

  C. Ethernet Linear Protection

  D. STP

  Correct Answer: B

• Question 252:

  Which option should be part of your network design to support dynamic mutual redistribution between multiple OSPFv2 and IS-IS boundaries, to avoid suboptimal routing?

  A. route tagging and administrative policies

  B. route filtering and administrative policies

  C. route aggregation and administrative policies

  D. disabling IS-IS wide metrics

  Correct Answer: B

• Question 253:

  Service provider XYZ wants to implement IPv6 on their MPLS network using MPLS 6PE or 6VPE techniques. Currently XYZ providers IPv4 multicast services over an MPLS network by using MVPN, and wants to provide parallel IPv6 multicast services. Which two multicast solutions enable the IPv6 multicast services? (Choose 2)

  A. MVPN for IPv6 multicast service

  B. MPLS 6PE, because it provides IPv6 multicast support by default

  C. PIM-DM to enable IPv6 multicast in conjunction with MPLS 6PE/6VPE

  D. an overlay model using Layer 2 MPLS tunnels

  E. MPLS 6VPE, because it provides IPv6 multicast support by default

  Correct Answer: AD

• Question 254:

  Which statement about TAP and TUN devices, which are used in a Linux/KVM cloud deployment model, is true?

  A. TUN is for handling Ethernet frames, but TAP is for handling IP packets.

  B. TUN is for handling IP packets, but TAP is for handling Ethernet frames.

  C. TUN is for tunneling Ethernet frames, but TAP is for tapping Ethernet frames.

  D. TUN is for tunneling IP packets, but TAP is for tapping IP packets.

  Correct Answer: B

• Question 255:

  Which option is a critical mechanism to optimize convergence speed when using MPLS FRR?

  A. down detection

  B. shared risk link groups

  C. bandwidth reservation

  D. IGP timers

  Correct Answer: A

• Question 256:

  You are planning a migration to a dual-stack IPv4/1Pv6 campus environment while providing a flexible and scalable design with fault isolation. The design should allow IPv6 devices to tunnel over portions of the campus that are not yet natively IPv6-enabled, including wireless and voice endpoints. Your plan requires an interim approach that allows for a faster introduction of new services without requiring a network wide hot cutover. Which two services block functions meet these requirements? (Choose 2)

  

  A. IPv6 ISATAP tunnel termination point

  B. policy gateways

  C. GRE tunnel to the local Internet edge

  D. BGP route reflectors

  E. GET VPN key server

  Correct Answer: AC

• Question 257:

  A mobile network operator is designing an NGN backhaul and plans to migrate their legacy SDH and SONET-based transport network to a packet-based transport network. The NGN network must achieve similar failover and failback times as the legacy network (50 milliseconds). Which method does allow for similar failover and failback times on the new packet-based network?

  A. BFD

  B. E-OAM

  C. UDLC

  D. BPDU

  Correct Answer: B

• Question 258:

  Which resource will be targeted by a TCP SYN flood attack?

  A. connection tables on the target host

  B. send buffers on transit routers

  C. SYN cookies on the target host

  D. shared memory on the routers closest to the target

  Correct Answer: A

• Question 259:

  Which two options are reasons for designing a large OSPF network with multiple areas connected to the backbone? (Choose 2)

  A. Reduce the number of routes within an area.

  B. Route tagging capability.

  C. Enhance failure detection.

  D. Simplify logical topology.

  E. Reduces SPF algorithm runs.

  Correct Answer: AE

• Question 260:

  Your company wants to sell its marketing research data to its strategic partners. All strategic partners currently have a Multipoint GRE VPN setup to your hub remote access routers, and are running a separate OSPF process over the Multipoint GRE VPN with you. Your internal IGP is also OSPF, and the internal application used to access the marketing research data is located within your company's data center. Which solution ensures the strategic partners are provided with only the access they need, and that both organization's routing designs are not negatively affected?

  

  A. Redistribute and tag only internal routes from the strategic partner's OSPF to your internal OSPF and send them only your data center routes. The tagged routes are not advertised to your local SP for internet connectivity.

  B. Redistribute and tag all routes from the strategic partner's OSPF to your internal OSPF and send them only your data center routes. The tagged routes are advertised to your local SP for Internet connectivity.

  C. Redistribute and tag only internal routes from the strategic partner's OSPF to your internal OSPF and send them all your organization's routes. The tagged routes are advertised to your local SP for Internet connectivity.

  D. Redistribute and tag all routes from the strategic partner's OSPF to your internal OSPF and send them a default route. The tagged routes are not advertised to your local SP for Internet connectivity.

  Correct Answer: C
