Cisco Cisco Certifications 352-001 Questions & Answers

• Question 371:

  Which two statements are correct about Layer 3 fast convergence? (Choose two.)

  A. Switch routed interfaces converge faster than SVI interfaces.

  B. Routing protocol timers that are tuned aggressively increase the control plane's CPU utilization.

  C. Layer 3 down detection is faster than Layer 1 and Layer 2 mechanisms.

  D. Interface dampening with routing protocol timers that are tuned low improve convergence time.

  E. Fiber cable provides faster convergence than UTP cable.

  Correct Answer: AB

• Question 372:

  Which two options are considered risks or concerns when both the Internet and VPN service functions are on the same PE router? (Choose two.)

  A. Internet-based attacks can affect VPN customers.

  B. BGP cannot simultaneously run on the PE router that runs MPLS.

  C. MP-BGP prefixes increase routers' global routing tables, which affects network convergence.

  D. Failure on the PE router affects both VPN and Internet services.

  E. Customer performance can be affected by VPN traffic if Internet-based traffic is not prioritized on the PE.

  Correct Answer: AD

• Question 373:

  You must measure the amount of traffic that a mobile packet gateway produces when mobile phones access the service provider's internal applications, rather than the Internet. Backbone queuing can be properly designed as a result of this analysis. This traffic is in the multiple Gigabits per second order of magnitude.

  Which three actions can you take to allow this visibility? (Choose three.)

  A. Poll OID that is configured for internal servers with SNMP.

  B. Collect traffic information that is related to internal server IP addresses with NetFlow.

  C. Measure traffic characteristics of known internal servers with IP SLA.

  D. Collect information about traffic to the service provider marked with IP precedence with NetFlow.

  E. Analyze traffic volumes with deep packet inspection.

  Correct Answer: BDE

• Question 374:

  What are three tools for ongoing monitoring and maintenance of a voice and video environment? (Choose three.)

  A. active monitoring via synthetic probes to measure loss, latency, and jitter

  B. passive monitoring via synthetic probes to measure loss, latency, and jitter

  C. flow-based analysis to measure bandwidth mix of applications and their flows

  D. flow-based analysis with PTP time-stamping to measure loss, latency, and jitter

  E. call management analysis to identify CAC failures and call quality issues

  Correct Answer: ACE

• Question 375:

  Which three methods allow storage access across an IP network? (Choose three.)

  A. FCIP

  B. Fiber Channel over GRE

  C. Fiber Channel over L2TPv3

  D. iSCSI

  E. NFS

  Correct Answer: ADE

• Question 376:

  You have been tasked with designing a data center interconnect to provide business continuity. You want to encrypt the traffic over the DCI using IEEE 802.1AE MACsec to prevent the deployment of any firewall or IPS. Which two interconnect technologies support MACsec? (Choose two.)

  A. EoMPLS

  B. MPLS Layer 3 VPN

  C. DMVPN

  D. OTV

  E. VPLS

  F. GET VPN

  Correct Answer: AE

• Question 377:

  Which two OSPF network type combinations can you use in the design of a Phase 3 DMVPN that requires spoke-to-spoke direct traffic? (Choose two.)

  A. hub as point-to-multipoint and spokes as non-broadcast

  B. hub as point-to-multipoint and spokes as point-to-point

  C. hub as broadcast and spokes as non-broadcast

  D. hub as point-to-point and spokes as point-to-point

  Correct Answer: BC

• Question 378:

  Refer to the exhibit.

  

  Your company designed a network to allow server VLANs to span all access switches in a data center. In the design, Layer 3 VLAN interfaces and HSRP are configured on the aggregation switches.

  Which two features will improve STP stability within the network design? (Choose two.)

  A. BPDU guard on access ports

  B. Edge port on access ports

  C. Root guard on access ports

  D. BPDU guard on the aggregation switch downlinks toward access switches

  E. Root guard on the aggregation switch downlinks toward access switches

  F. Access switch pairs are explicitly determined to be root and backup root bridges

  Correct Answer: AE

• Question 379:

  What are two design characteristics of GETVPN? (Choose two.)

  A. It uses GDOI to distribute keys.

  B. It supports private addresses over public Internet.

  C. It requires multicast replication at the hub.

  D. It uses tunnel-less technology.

  E. It supports dynamic partial- or full-mesh tunnels.

  Correct Answer: AD

• Question 380:

  A customer is running OSPF on a broadcast network type in a DMVPN single-hub, single- cloud topology and dynamically routes from the data center to the branch networks. The customer wants to speed up convergence and to avoid having to elect DRs by changing the network type to point-to-multipoint at the data center and to point-to-point at the branches. Which option will meet the fast convergence requirement and not break any OSPF neighbor adjacencies when this redesign is implemented?

  A. The OSPF area containing the branch office routers should be set to stubby.

  B. The OSPF neighbors should be set manually at the data center router.

  C. The OSPF hello and dead timers should be adjusted at the data center router to match the timers at the remote sites.

  D. The OSPF database should be cleared manually for the new network types to take effect.

  E. The interface MTU sizes should be increased on all routers.

  Correct Answer: C
