Question 21

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 22

You are presented with requirements to design a development, testing and production environments. These environment should communicate with each other, yet they should be kept as separate failure domains. Which routing protocol should be configured on the links between the networks to support the design requirements?

A. OSPF
B. EIGRP
C. IS-IS
D. BGP

Correct Answer:D

Question 23

Which reason prevents a designer from using a GDOI-based VPN to secure traffic that traverses the
Internet?

A. Enterprise host IP addresses are typically not routable.
B. GDOI is less secure than traditional IPsec.
C. Network address translation functions interfere with tunnel header preservation.
D. The use of public addresses is not supported with GDOI.

Correct Answer:C

Question 24

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 25

Refer to the exhibit.
352-001 dumps exhibit
A customer currently has a large EIGRP-based network with several remote sites attached. All remote sites connect to the two corporate data centers, depicted as 10.1.1.0 and 10.1.2.0. The customer has experienced several network-wide failures where neighbors were stuck-in-active and had other network stability issues due to some links flapping. Which two redesign options increase stability and reduce the load on the remote site routers, still maintaining optimal routing between remote sites and the two data centers? (Choose two)

A. Set the data center routers as stub-routers
B. Perform summarization at the data centers, selectively leaking routes sent to the remote sites
C. Perform summarization at the remote sites, selectively leaking routes sent to the data centers
D. Set the hello interval timer to be larger than the hold interval
E. Increase the hold interval to accommodate lost hello packets on error-prone links

Correct Answer:AB
