• Question 21:

  When designing a network that uses IPsec, which technique is suggested to avoid network fragmentation?

  A. Reduce the MTU on the side closest to the server

  B. Reduce the MTU on both ends of the TCP connection

  C. Reduce the MTU on the side closest to the client

  D. Reduce the MTU only in the WAN

  Correct Answer: B

• Question 22:

  An enterprise company is attaching to a new Gigabit Ethernet-based link from the local service provider. This connection must have a 150 Mbps committed information rate.

  For the design of this new service, which QoS mechanism must be used to ensure low packet loss within the service provider network?

  A. policing

  B. LLQ

  C. shaping

  D. CBWFQ

  Correct Answer: C

• Question 23:

  Which statement about traffic shaping is true?

  A. It works by minimizing data transmission intervals

  B. It separates data packets based on certain characteristics by using NBAR

  C. It regulates data transmission patterns into the network

  D. It enforces an upper limit on bursty data traffic

  Correct Answer: D

• Question 24:

  Which two fast reroute technologies provide the highest level of protected path coverage in a ring topology? (Choose two.)

  A. per-prefix LFA

  B. remote LFA

  C. automatic protection switching

  D. MPLS TE FRR

  E. per-link LFA

  Correct Answer: BD

• Question 25:

  Which design benefit of Bridge Assurance is true?

  A. It prevents switch loops caused by unidirectional point-to-point link condition on Rapid PVST+ and MST

  B. It allows small, unmanaged switches to be plugged into ports of access switches without the risk of switch loops

  C. It prevents switched traffic from traversing suboptimal paths on the network

  D. It suppresses a spanning-tree topology change upon connecting and disconnecting a station on a port

  Correct Answer: D

• Question 26:

  Refer to the exhibit. ACME Mining has four data centers in Santiago, Cape Town, Mumbai, and Beijing. They are full-mesh connected via a 400 Mb/s EVP-LAN. A 1-TB file transfer occurs daily via FTP between the Santiago and Mumbai data

  centers. When testing, this data transfer took an "unexpected and outrageous" 6 hours, with an average transfer rate of 47 KB/s. The network team provided this information:

  LAN bandwidth usage was below 5% at both data centers during transfer.

  WAN bandwidth usage was between 20-30% at both data centers during transfer.

  The only QoS on WAN is 200 Kb/s strict priority configured for other types of traffic.

  There is no QoS on LAN.

  The ping RTT average between data centers is 378 milliseconds.

  

  Which action improves the file transfer rate?

  A. Classify the FTP transfer and use the strict priority queue on the WAN

  B. Use TFTP instead of FTP

  C. Apply WAN optimization techniques at both data centers

  D. Use SFTP instead of FTP

  Correct Answer: B

• Question 27:

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

  A. prefix suppression

  B. RLFA

  C. RSVP-TE

  D. LFA

  Correct Answer: D

• Question 28:

  For which two reasons would you deploy an IDS sensor in promiscuous mode when designing a security solution? (Choose two.)

  A. The solution stops malicious traffic from reaching its intended target

  B. The solution allows denying packets inline

  C. The solution is resistant to sensor failure

  D. The solution allows for stream normalization

  E. The solution allows for signature-based pattern matching

  Correct Answer: CE

• Question 29:

  What are three common objectives for customers using multiple cloud providers? (Choose three.)

  A. high availability

  B. bandwidth

  C. security

  D. analytics

  E. feature disparity

  F. regional provider access

  Correct Answer: ABC

• Question 30:

  Video traffic is being distributed across a large WAN network. The video source originates from different parts of the multicast domain at different times.

  Which multicast technology provides optimal path selection between the receiver and the source for this multicast traffic?

  A. Source Specific Multicast

  B. PIM sparse mode

  C. Bidirectional PIM

  D. Any Source Multicast

  Correct Answer: A
