IT 341 Final - Chp. 1 Review

Refer to the exhibit. How many broadcast domains are displayed?

8

What is the destination address in the header of a broadcast frame?

???

A local law firm is redesigning the company network so that all 20 employees can be connected to a LAN and to the Internet. The law firm would prefer a low cost and easy solution for the project. What type of switch should be selected?

fixed configuration

Which type of address does a switch use to build the MAC address table?

source MAC address

Which network device can be used to eliminate collisions on an Ethernet network?

switch

Consider that the main power has just been restored. PC3 issues a broadcast IPv4 DHCP request. To which port will SW1 forward this request?​

to Fa0/1, Fa0/2, and Fa0/3 only

Which two previously independent technologies should a network administrator attempt to combine after choosing to upgrade to a converged network infrastructure?

-VoIP phone traffic -mobile cell phone traffic

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

-simpler deployment for additional switch equipment -lower bandwidth requirements

How many collision domains are shown in the topology?

2???

Which statement describes the microsegmentation feature of a LAN switch?

Each port forms a collision domain.

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

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

What is a collapsed core in a network design?

a combination of the functionality of the distribution and core layers

match the functions to the corresponding layers

access layer: -represents the network edge -provides network access to the user distribution layer: -establishes Layer 3 routing boundaries -implements network access policy core layer: -provides high-speed backbone connectivity -functions as an aggregator for all the campus blocks

What is one function of a Layer 2 switch?

aggregating Layer 3 routing boundaries

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

to isolate traffic between segments to enhance user bandwidth

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

converged

match the forwarding characteristics to its type:

cut-through: -may forward invalid frames -appropriate for high performance computing applications store-and-forward: -error checking before forwarding -forwarding process only begins after receiving the entire frame

What is a definition of a two-tier LAN network design?

distribution and core layers collapsed into one tier, and the access layer on a separate tier

match the borderless switched network guideline to the principle. allows intelligent traffic load sharing by using all network resources allows seamless network expansion and integrated service enablement on an on-demand basis facilitates understanding the role of each device at every tier, simplifies deployment, operation, management, and reduces fault domains at every tier satisfies user expectations for keeping the network always on

flexibility modularity hierarchical resiliency

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

increased scalability need for fewer power outlets

What two criteria are used by a Cisco LAN switch to decide how to forward Ethernet frames? (Choose two.)

ingress port destination MAC address

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

providing access to end user devices???
