100-150 Question 4
Single answerA network engineer is tasked with ensuring that all devices in a new office can communicate over the LAN and adhere to a universal set of communication rules. The engineer decides to implement a standard for Ethernet communication. Which standard should the engineer follow to ensure compatibility across devices?
- A
IEEE 802.11
- B
IEEE 802.3
- C
IEEE 802.15
- D
IEEE 802.1X
Show answer and explanation
Correct answer: B
Explanation
The IEEE 802.3 standard defines Ethernet communication, which is the most commonly used standard for wired Local Area Networks (LANs). It ensures compatibility between devices by providing a set of rules for data transmission over wired connections. In this scenario, the network engineer needs to implement IEEE 802.3 to ensure proper communication over the LAN.
- A. Incorrect.
IEEE 802.11 is the standard for wireless LAN (Wi-Fi) communication, not Ethernet.
- B. Correct.
IEEE 802.3 is the standard for Ethernet communication, defining how devices communicate over wired LANs.
- C. Incorrect.
IEEE 802.15 is the standard for Personal Area Networks (PANs), such as Bluetooth, not Ethernet communication.
- D. Incorrect.
IEEE 802.1X is a standard for network access control, focusing on authentication mechanisms, not Ethernet communication.
