Question

Select the correct statement(s) regarding switched Ethernet LANs.

a. Ethernet switches must read the destination addresses of each incoming data packet in order to determine which outgoing port it should be sent through
b. data collisions do not occur on switched Ethernet LANs that are configured in full-duplex (FDX) mode
c. with HDX (half-duplex) switched Ethernet, use of CDMA/CD is still required since data collisions can occur
d. all statements are correct

Answer 1

Ethernet switches read destination addresses to determine outgoing ports; in FDX mode, data collisions don't occur; in HDX mode, CSMA/CD is needed due to possible collisions. All statements are correct.

Step-by-step explanation:

Select the correct statement(s) regarding switched Ethernet LANs:

• Ethernet switches must read the destination addresses of each incoming data packet in order to determine which outgoing port it should be sent through.
• Data collisions do not occur on switched Ethernet LANs that are configured in full-duplex (FDX) mode.
• With HDX (half-duplex) switched Ethernet, use of CSMA/CD is still required since data collisions can occur.
• All statements are correct.

Each of these statements accurately reflects how Ethernet switches function and how they handle data packets and potential collisions.
