Cisco Cisco Certifications 352-001 Questions & Answers

• Question 121:

  You are designing dual-homed active/active ISP connections from an enterprise customer for internet services, and you have recommended BGP between the customer and ISP. When three security mechanisms do you enable to secure the connection? (Choose three)

  A. uRPF is strict mode

  B. remote triggered black holes

  C. IDS

  D. GTSM

  E. Routing protocol authentication

  F. uRPF in loose mode

  Correct Answer: BEF

• Question 122:

  Which option describes the fundamental design differences between an IP-based network design and a SAN-based?

  A. An IP-based design has redundant connectivity in the fabric and high amounts of east-west traffic, whereas a SAN-based design uses redundancy from a dual-attached host, which uses separate fabrics and has very little east-west traffic

  B. An IP-based design has redundancy from the host and high amounts of east-west traffic, whereas a SAN-based design uses redundancy in the fabric and very little east-west traffic

  C. An IP-based design has redundant connectivity in the fabric and high amounts of east-west traffic, whereas a SAN-based design uses zoning based redundancy which uses separate fabrics and has very little east-west traffic

  D. An IP-based design has redundant connectivity in the fabric and very little east-west traffic, whereas a SAN-based design uses redundancy in the host, which uses separate fabrics and has high amounts of east-west traffic

  Correct Answer: A

• Question 123:

  You are asked to design an RSVP-TEL LSP protection solution for a large service provider network .

  Which traffic protection mechanism is highly scalable and ensure that multiple LPS always terminate at the same merge point?

  A. Shared explicit protection.

  B. Detour LSPs.

  C. 1:N protection.

  D. 1:1 protection.

  Correct Answer: C

• Question 124:

  Refer to the exhibit.

  

  You must review this single OSPF area, DMVPN network because the company has noticed a few area 0 convergence and stability issues. Also, traffic destined to the data center from one of the spokes as the next hop on the path. The

  company prefers that all traffic destined to the data center uses the least amount of hops.

  Which solution resolves these issues with the minimum amount of changes on the network?

  A. Migrate from OSPF to static routes between the hub routers and the spoke routers and deploy IP SLA for route health checks

  B. Migrate from OSPF to EIGRP between the hub routers and the spoke routers

  C. Modify OSPF cost metrics on all backup links

  D. Create areas between each hub and their spoke routers, to ensure that the hub routers become DRs

  Correct Answer: C

• Question 125:

  Which three network management requirements are common practices in network design? (Choose three)

  A. Collect RMON poll information for future regression analysis

  B. Ensure that all network devices have their clocks synchronized

  C. Look at average counters instead of instantaneous counters for inconsistent and bursty KPIs, such as CPU utilization and interface utilization.

  D. Collect SNMP poll information for future regression analysis

  E. Validate data plane health, application and services availability with synthetic traffic

  F. Capture both ingress and egress flow-based packets. While avoiding duplications of flows

  Correct Answer: BCD

• Question 126:

  Which option reduces jitter in a VoIP network?

  A. Deploy WRED

  B. Deploy call Admission Control

  C. Adjust the playout delay buffer at the receiver

  D. Increase the bandwidth of the links

  Correct Answer: C

• Question 127:

  In an Ethernet link containing five routers with OSPF network interface type configured as broadcast, how many OSPF adjacencies are established on this Ethernet link?

  A. 7

  B. 5

  C. 10

  D. 20

  E. 6

  Correct Answer: A

• Question 128:

  A DMVPN network is being deployed for 10 branch sites to connect to the central headquarters over the Internet. Each branch site connects to the internet via a 1.5 Mb/s ADSL line, and the headquarters connects to the Internet over a

  100Mb/s circuit limited to 20 Mb/s by the service provider.

  Which QoS mechanism if any, do you recommend at the headquarters location?

  A. Rate-limiting the 100 Mb/s circuit to 20 Mb/s

  B. Applying hierarchical QoS with parent policy for the overall circuit and child policy for the spokes

  C. Traffic shaping the 100 Mb/s circuit to 20 Mb/s

  D. QoS is not required in this instance due to maximum traffic being received by the branches being 15 Mb/s

  Correct Answer: B

• Question 129:

  Refer to the exhibit.

  

  How should you redesign this network running BGP to improve availability of the routers 1A and 1B at the core site?

  A. Deploy BGP PIC

  B. Use link bundles over multiple slots

  C. Enable graceful restart

  D. Create a multichassis system with the two routers

  Correct Answer: A

• Question 130:

  What is an advantage of placing the IS-IS flooding domain boundary at the core Layer in a three-layer hierarchical network?

  A. The L1 and L2 domains can easily overlap

  B. The L2 domain is contained and more stable

  C. It can be applied to any kind of topology

  D. It reduces the complexity of the L1 domains

  Correct Answer: A
