CCNA S2 Chapter 4

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

FF-FF-FF-FF-FF-FF

Which statement describes a result after multiple Cisco LAN switches are interconnected?

The broadcast domain expands to all switches.

What is a collapsed core in a network design?

a combination of the functionality of the distribution and core layers

Which solution would help a college alleviate network congestion due to collisions?

a high port density switch

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

aggregating Layer 3 routing boundaries

what type of network uses one common infrastructure to carry voice, data, and video signals?

converged

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

destination MAC address, ingress port

What is one function of a Layer 2 switch?

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

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

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

A network designer must provide a rationale to a customer for a design which will move an enterprise from a flat network topology to a hierarchical network topology. Which two features of the hierarchical design make it the better choice?

easier to provide redundant links to ensure higher availability, simpler deployment for additional switch equipment

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

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

increased scalability, need for fewer power outlets

Which network device can serve as a boundary to divide a Layer 2 broadcast domain?

routers

A small publishing company has a network design such that when a broadcast is sent on the LAN, 200 devices receive the transmitted broadcast. How can the network administrator reduce the number of devices that receive broadcast traffic?

segment the LAN into smaller LANs and route between them

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

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

the number of available ports

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

to enhance user bandwidth, to isolate traffic between segments

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

user data traffic, VoIP phone traffic
