Flashcards in 3-1: Introduction to Scaled Networks Deck (21):
1

In which situation would a network administrator install a Cisco Nexus Series or Cisco Catalyst 6500 Series switch to promote infrastructure scalability?

On a data center network to provide expansion and transport flexibility

2

What purpose does a hostname serve?

Identification

2

Which two features of enterprise class equipment assists an enterprise network in maintaining 99.999 percent up-time?

1. redundant power supplies 2. failover capabilities

3

What purpose to password serve?

Security

3

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

Q image thumb

PC_3 and AP_2

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?

A modular router

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?

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

6

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

Grouping multiple physical ports to increase bandwidth between two switches

7

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

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

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?

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

10

How can an enterprise network be designed to optimize bandwidth?

By organizing the network to control traffic patterns

11

Which statement describes a characteristic of Cisco Catalyst 2960 switches?

New Cisco Catalyst 2960-C switches support PoE pass-through.

12

What are two functions of a router?

1. It determines the best path to send packets. 2. It connects multiple IP networks.

13

Why would you assign IP addresses to interfaces?

Connectivity.

14

Why would a network administrator issue the show cdp neigbors command on a router?

To display device ID and other information about directly connected Cisco devices

15

Which technology is required when switched networks are designed to include redundant links?

Spanning Tree Protocol

17

Which design feature will limit the size of a failure domain in an enterprise network?

The use of the building switch block approach

18

What purpose do routing protocols serve?

Access remote networks

19

Which statement describes a characteristic of Cisco Meraki switches?

They are cloud-managed access switches that enable virtual stacking of switches.

20

What is a characteristic of in-band device management?

It is used to monitor and make configuration changes to a network device over a network connection.*

21

What are two benefits of extending access layer connectivity to users through a wireless medium?

1. reduced costs 2. increased flexibility
