When a collision occurs in a network using CSMA/CD, how do hosts with data to transmit respond after the backoff period has expired?

The hosts return to a listen-before-transmit mode.

After an Ethernet collision, when the backoff algorithm is invoked, which device has priority to transmit data?
any device in the collision domain whose backoff timer expires first

Which of the following is a drawback of the CSMA/CD access method?
Collisions can decrease network performance.

Refer to the exhibit. The switch and workstation are administratively configured for full-duplex operation. Which statement accurately reflects the operation of this link?
No collisions will occur on this link.

Why do hosts on an Ethernet segment that experience a collision use a random delay before attempting to transmit a frame?
A random delay helps prevent the stations from experiencing another collision during the transmission.

In the graphic, Host A has reached 50% completion in sending a 1 KB Ethernet frame to Host D when Host B wishes to transmit its own frame to Host C. What must Host B do?
Host B must wait until it is certain that Host A has completed sending its frame.

Ethernet operates at which layers of the OSI model? (Choose two.)
Physical layer

Data-link layer

What does the IEEE 802.2 standard represent in Ethernet technologies?
Logical Link Control sublayer

Which statements correctly describe MAC addresses? (Choose three.)
copied into RAM during system startup

contains a 3 byte OUI

6 bytes long

Refer to the exhibit. Host_A is attempting to contact Server_B. Which statements correctly describe the addressing Host_A will generate in the process? (Choose two.)
A frame with the destination MAC address of Router_A.

A packet with the destination IP of Server_B.

Host A has an IP address of 172.16.225.93, a mask of 255.255.248.0, and a default gateway of 172.16.224.1. Host A needs to send a packet to a new host whose IP is 172.16.231.78. Host A performs the ANDing operation on its address and subnet mask. What two things will occur? (Choose two.)
Host A will get a result of 172.16.224.0 from the AND process.

Host A will broadcast an ARP request for the MAC of the host 172.16.231.78.

Which two features make switches preferable to hubs in Ethernet-based networks? (Choose two.)
minimizing of collisions

increase in the throughput of communications

Ethernet operates at which layer of the TCP/IP network model?
network access

What are three functions of the upper data link sublayer in the OSI model? (Choose three.)
identifies the network layer protocol

makes the connection with the upper layers

insulates network layer protocols from changes in physical equipment
