Back 1

* failover capabilities
* redundant power supplies

Front 2

How can an enterprise network be designed to optimize bandwidth?

Front 3

In the Cisco Enterprise Architecture, which two functional parts of the network are combined to form a collapsed core design?

Back 3

* core layer
* distribution layer

Front 4

What network design would contain the scope of disruptions on a network should a failure occur?

Back 4

* the deployment of distribution layer switches in pairs and the division of access layer switch connections between them

Front 5

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

Back 5

* the use of the building switch block approach

Front 6

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?

Back 6

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

Front 7

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

Back 7

* increased flexibility
* reduced costs

Front 8

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

Back 8

* grouping multiple physical ports to increase bandwidth between two switches

Front 9

Which statement describes a characteristic of Cisco Meraki switches?

Back 9

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

Front 10

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

Back 10

* on a data center network to provide expansion and transport flexibility

Front 11

Which statement describes a characteristic of Cisco Catalyst 2960 switches?

Back 11

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

Front 12

What is the function of ASICs in a multilayer switch?

Back 12

* They streamline forwarding of IP packets in a multilayer switch by bypassing the CPU.

Front 13

What is the function of PoE pass-through?

Back 13

* allows switches, phones, and wireless access points to receive power over existing Ethernet cables from an upstream switch

Front 14

What term is used to express the thickness or height of a switch?

Back 14

* rack unit

Front 15

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?

Back 15

* a modular router

Front 16

What are two functions of a router?

Back 16

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

Front 17

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

Back 17

* at least one network interface that is connected and operational
* Telnet, SSH, or HTTP access to the device

Front 18

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?

Back 18

* show startup-config
* show running-config

Front 19

What are two ways to access a Cisco switch for out-of-band management?

Back 19

* a connection that uses the console port
* a connection that uses the AUX port

Front 20
