Cisco CCNP Enterprise 300-420 Questions & Answers

• Question 201:

  Which two best practices must be followed when designing an out-of-band management network? (Choose two.)

  A. Enforce access control

  B. Facilitate network integration

  C. Back up data using the management network

  D. Ensure that the management network is a backup to the data network

  E. Ensure network isolation

  Correct Answer: AE

• Question 202:

  Refer to the exhibit.

  

  An engineer must optimize the traffic flow of the network. Which change provides a more efficient design between the access and the distribution layer?

  A. Add a link between access switch A and access switch B

  B. Reconfigure the distribution switch A to become the HSRP Active

  C. Change the link between distribution switch A and distribution switch B to be a routed link

  D. Create an EtherChannel link between distribution switch A and distribution switch B

  Correct Answer: B

• Question 203:

  A network engineer must connect two sites across a public network using a secure tunneling technology that supports multicast traffic. Which technology must be chosen?

  A. IPsec

  B. GRE

  C. PPTP

  D. GRE over IPsec

  Correct Answer: D

• Question 204:

  A router running ISIS is showing high CPU and bandwidth utilization. An engineer discovers that the router is configured as L1/L2 and has L1 and L2 neighbors. Which step optimizes the design to address the issue?

  A. Make this router a DIS for each of the interfaces

  B. Disable the default behavior of advertising the default route on the L1/L2 router

  C. Configure the router to be either L1 or L2

  D. Configure each interface as either L1 or L2 circuit type

  Correct Answer: D

• Question 205:

  An infrastructure team is concerned about the shared memory utilization of a device, and for this reason, they need to monitor the device state. Which solution limits impact on the device and provides the required data?

  A. IPFIX

  B. static telemetry

  C. on-change subscription

  D. periodic subscription

  Correct Answer: D

  Memory usage is measured in bytes and changes very frequently. On-change subscription will send data almost non-stop. In this case periodic change is more suitable.

• Question 206:

  What are two valid scaling techniques when an EIGRP network is designed that consists of more than routers? (Choose two.)

  A. Use structured hierarchical topology with route summarization

  B. Used sub-second timers

  C. Use the distribute-list command to filter routes

  D. Modify delay parameters on the links

  E. Implement multiple EIGRP autonomous systems

  Correct Answer: AE

• Question 207:

  Refer to the exhibit.

  

  Which solution decreases the EIGRP convergence time?

  A. Enable subsecond timers

  B. Increase the hold time value

  C. Increase the dead timer value

  D. Enable stub routing on the spokes

  Correct Answer: D

• Question 208:

  Which method will filter routes between EIGRP neighbors within the same autonomous system?

  A. distribute-list

  B. policy-based routing

  C. leak-map

  D. route tagging

  Correct Answer: A

• Question 209:

  When vEdge router redundancy is designed, which FHRP is supported?

  A. HSRP

  B. OMP

  C. GLBP

  D. VRRP

  Correct Answer: D

• Question 210:

  Which feature is required for graceful restart to recover from a processor failure?

  A. Cisco Express Forwarding

  B. Virtual Switch System

  C. Stateful Switchover

  D. Bidirectional Forwarding Detection

  Correct Answer: C

  The Stateful Switchover (SSO) feature works with Nonstop Forwarding (NSF) in Cisco software to minimize the amount of time a network is unavailable to its users following a switchover. The primary objective of SSO is to improve the availability of networks constructed with Cisco routers.
