A type of network traffic where the same packet is delivered to all nodes on the same network is called what?

Broadcast Traffic multi- one to many uni- one to one broad-one to all

Which media access control technology will listen to a cable to ensure there is no traffic being transmitted before sending its traffic, but will implement a back-off timer if a collision does occur?

CSMA/CA (avoid) Back-off timer is avoid

All nodes shown in the following figure are in the same collision domain:

True (switches change them)

Your coworker just installed an unmanaged 24 port switch. He is concerened with the amount of broadcast traffic that may exist when using this device. How many broadcast domains are created when using this single 24-port switch?

1

In a standard ethernet frame format, the Start Frame delimiter (SFD) signified the end of the _________ and the transmission of the actual data begins.

Preamble Preamble (8 bytes of 1s and 0s )and SFD(two consecutive 1s at end) used for clock synching and part of CSMA/CD to identify collisions.

Which of the following devices is used to extend the signal strength on a network segment but does not make decisions on a traffic flow?

Repeater

Switch

Host A tries to establish a connection on a local network to host B and first sends an ARP request. Why does Host A Need to send an ARP request?

To discover the hardware address of Host B (ARP looks at hardware)

What is a correct representation of a valid 48-bit MAC address?

ac:79:d6:42:b2:08 or 00608ca23abc 12 characters from a-f and 0-9

A network administrator suspects an issue with local addressing. The administrator would like to view the entries of the address resolution protocol (ARP) table. Recommend the appropriate ARP utility command.

arp -a
