Question 80/89

Which of the following best describe the functions of Layer 2 of the OSI model? (Choose two.)

A. Local addressing

B. Error preventing

C. Logical addressing

D. Error detecting

E. Port addressing

F. Error correcting

Correct Answer: A,D

Layer 2 assigns physical addresses (MAC addresses) to network interface cards (NICs) for devices on a local network. These addresses are used for device-to-device communication within the same network segment.
Layer 2 includes error-detection mechanisms to ensure that data transmitted over the physical medium is free from errors or corruption. This error detection (not correction), ensures data integrity.
