Question 3

Which devices exist in the failure domain when switch S3 loses power?

Answer 3

PC_3 and AP_2

Question 4

A network engineer is reviewing a network design that uses a fixed configuration enterprise router that supports both LAN and WAN connections. However, the engineer realizes that the router does not have enough interfaces to support growth and network expansion. Which type of device should be used as a replacement?

Answer 4

A modular router

Question 4

Immediately after a router completes its boot sequence, the network administrator wants to check the routers configuration. From privileged EXEC mode, which of the following commands can the administrator use for this purpose?

Answer 4

1. show startup-config 2. show running-config

Question 6

As the network administrator you have been asked to implement EtherChannel on the corporate network. What does this configuration consist of?

Answer 6

Grouping multiple physical ports to increase bandwidth between two switches

Question 7

Which two requirements must always be met to use in-band management to configure a network device?

Answer 7

1. At least one network interface that is connected and operational 2. Telnet, SSH, or HTTP access to the device

Question 8

A network administrator is planning redundant devices and cabling in a switched network to support high availability. Which benefit will implementing the Spanning Tree Protocol provide to this design?

Answer 8

Redundant paths can be available without causing logical Layer 2 loops.

Question 10

How can an enterprise network be designed to optimize bandwidth?

Answer 10

By organizing the network to control traffic patterns
