• Question 71:

  Which solution prevents microloops from be formed during network convergence time?

  A. RSVP-TE

  B. LFA

  C. Prefix suppression

  D. RLFA

  Correct Answer: D

• Question 72:

  Company ABC grew organically and now their single-area OSPF network has an unacceptably slow convergence time after a topology change. To address the slow convergence time, they want to introduce a multiarea OSPF design and implement address summarization at the area border routers, which option should be their main concern about this redesign?

  A. Routing is suboptimal

  B. SPF calculation takes longer

  C. Operations complexity is increased

  D. More memory is needed across the routers on the network

  Correct Answer: A

• Question 73:

  The enterprise customer ABC Corp will deploy a centralized unified communications application to provide voice, and instant messaging to their branch offices. Some of the branch offices are located in remote locations and are connected via a 1.5 Mb/s Layer 3 VPN connection. Which two ways are the most cost-effective to ensure that this new application is implemented properly? (Choose two)

  A. Use a low bitrate codec such as G 711

  B. Set voice activity detection to avoid sending packets when the conversations is silent

  C. Enable VRF-Lite on the CE router to create a separate voice VRF

  D. Set LFI on the WAN connections to interleave the small voice packets with the large data packets

  E. Set WAN optimization on the CE router to compress the voice packets for improved bandwidth utilization and performance

  F. Use a low bitrate codec such as G 729

  Correct Answer: BF

• Question 74:

  Which native mechanism does OSPF use to prevent loops in MPLS VPNs?

  A. CE devices that run OSPF set the DN bit toward the PE router

  B. PE devices that run OSPF clear the DN bit toward the CE router

  C. CE devices that run OSPF clear the DN bit toward the PE router

  D. Creation of PE to PE OSPF sham link across the MPLS-created super backbone

  E. PE routers verify OSPF domain IDs used by CE OSPF processes

  F. PE devices that run OSPF set the DN bit toward the CE router

  Correct Answer: F

• Question 75:

  Which two components are the responsibility of the customers in a platform as a Service offering? (Choose two)

  A. Applications

  B. Infrastructure connectivity

  C. Hardware

  D. Data

  E. APIs

  Correct Answer: AD

• Question 76:

  An enterprise campus is adopting a network virtualization design solution with these requirements

  It must include the ability to virtualize the data plane and control plane by using VLANs and VRFs

  It must maintain end-to-end logical path transport separation across the network

  resources available grouped at the access edge

  Which two primary models can this network virtualization design be categorized? (Choose two)

  A. Path isolation

  B. Session isolation

  C. Group virtualization

  D. Services virtualization

  E. Edge isolation

  Correct Answer: AD

• Question 77:

  You are designing a new multisite data center network within the same city. You are using the newest routers that run OSPF and DWDM point-to-point interfaces for site-to-site connectivity. Your primary objective is to use the fastest possible method for interface failure detection. Which method achieves this objective?

  A. UDLD

  B. Interface event dampening

  C. LoS/AIS event faults

  D. Fast-hello timers

  Correct Answer: C

• Question 78:

  A multisite data center network runs OSPF and DWDM point-to-point interfaces for site to- site connectivity. Which method to detect interfaces the fastest?

  A. interface event dampening

  B. LoS/AJS event faults

  C. UDLD

  D. fast-hello> timers

  Correct Answer: B

• Question 79:

  A very large enterprise customer is migrating from EIGRP to IS-IS .What is your main concern in regards to change in the path packets take after the migration is complete?

  A. The areas sizes.

  B. The number of prefixes

  C. The redistribution points.

  D. The bandwidth and metrics of the links.

  Correct Answer: D

• Question 80:

  Which two options must be part of your network design to support dynamic mutual redistribution between multiple OSPFv2 and IS-IS boundaries, to avoid suboptimal routing? (Choose two)

  A. Matching OSPF external routes

  B. Route aggregation

  C. Route tagging

  D. Route filtering

  E. Disabling IS-IS wide metrics

  Correct Answer: CD
