Flashcards in 2-1: Introduction to Switched Networks Deck (22):
1

What does the access layer provide? [1.1.1.3]

Connectivity for the users.

2

Which type of transmission does a switch use when the destination MAC address is not contained in the MAC address table?

Broadcast

3

What is a basic function of the Cisco Borderless Architecture distribution layer?

Aggregating Layer 3 routing boundaries

4

How many collision domains are in the topology?​

Q image thumb

12.  Each link is a collision domain.

5

What information is added to the switch table from incoming frames?

Source MAC address and incoming port number

6

What are two advantages of modular switches over fixed-configuration switches?

  1. Need for fewer power outlets
  2. Increased scalability

7

What is a collapsed core in a network design?

A combination of the functionality of the distribution and core layers

8

ABC, Inc. has about fifty hosts in one LAN. The administrator would like to increase the throughput of that LAN. Which device will increase the number of collision domains and thereby increase the throughput of the LAN?

A switch

9

Which forwarding type may forward invalid frames?

Cut-through

10

Which forwarding type is appropriate for high performance computing applications?

Cut-through

11

Which forwarding type checks for frame errors before forwarding it?

Store-and-Forward

12

What is a basic function of the Cisco Borderless Architecture access layer?

Provides access to the user

13

Which two features of the hierarchical design make it the better choice?

  1. Easier to provide redundant links to ensure higher availability
  2. Simpler deployment for additional switch equipment

14

An administrator purchases new Cisco switches that have a feature called StackPower. What is the purpose of this feature?

It enables the sharing of power among multiple stackable switches.

15

How is a frame sent from PCA forwarded to PCC if the MAC address table on switch SW1 is empty?

Q image thumb

SW1 floods the frame on all ports on SW1, excluding the port through which the frame entered the switch.

16

What does the term “port density” represent for an Ethernet switch?

The number of available ports

17

How many broadcast domains are in the topology.​

Q image thumb

5.

18

What is one advantage of using the cut-through switching method instead of the store-and-forward switching method?

Has a lower latency appropriate for high-performance computing applications​

19

What are two reasons a network administrator would segment a network with a Layer 2 switch?

  1. To isolate traffic between segments
  2. To enhance user bandwidth

20

Which switch form factor should be used when large port density, fault tolerance, and low price are important factors?

Stackable switch

21

A ________ network is one that uses the same infrastructure to carry voice, data, and video signals.

Converged

22

What is one function of a Layer 2 switch?

Determines which interface is used to forward a frame based on the destination MAC address
