Frank is a network technician working for a medium-sized law firm in Memphis. Frank and two other IT employees take care of all the technical needs for the firm. The firm's partners have asked that a secure wireless network be implemented in the office so employees can move about freely without being tied to a network cable. While Frank and his colleagues are familiar with wired Ethernet technologies, 802.3, they are not familiar with how to setup wireless in a business environment. What IEEE standard should Frank and the other IT employees follow to become familiar with wireless?

Answer options

A: The IEEE standard covering wireless is 802.9 and they should follow this.

B: 802.7 covers wireless standards and should be followed

C: They should follow the 802.11 standard Correct answer

D: Frank and the other IT employees should follow the 802.1 standard.

Correct Answer:

C. They should follow the 802.11 standard

Explanation

The IEEE 802.11 standard is the globally recognized family of technical specifications for Wireless Local Area Network (WLAN) technology, commonly known as Wi-Fi. It defines the protocols for the physical (PHY) and medium access control (MAC) layers of the network. Any IT professional tasked with implementing a business-grade wireless network must be familiar with the 802.11 standards, including its various amendments (e.g., 802.11n, 802.11ac, 802.11ax) and associated security protocols like WPA3 to ensure a secure and efficient deployment.

Why Incorrect

A: IEEE 802.9 was a standard for Integrated Services LAN (ISLAN) to combine different traffic types, but it was not widely adopted for wireless. B: IEEE 802.7 was a standard for broadband LANs using coaxial cable and is not relevant to modern wireless networking. D: IEEE 802.1 is a set of standards related to network management, port-based access control (802.1X), and LAN/MAN bridging, not the core wireless protocols.
