Question

Please answer the following questions. (Answer only if you are really sure). Please don't guess

What is true regarding the IEEE 802.11 WLAN standard?

		a. WLANs operate in the licensed operating frequencies, therefore data collisions do not occur.
		b. Since 802.11 WLANs implement DSSS and OFDM, there is no need for a collision avoidance mechanism.
		c. The 802.11 Point Coordination Function (PCF) is an optional feature that enables the WLAN to operate as a centralized access network.
		d. 802.11 networks only implement centralized access using access points (APs)

The IEEE 802.3 Ethernet standard does not address fiber optic medium. It only includes UTP or shielded UTP mediums.

True

False

Answer 1

1.among the four options the correct option is

The 802.11 Point Coordination Function (PCF) is an optional feature that enables the WLAN to operate as a centralized access network.

so option c is correct answer

2.The IEEE 802.3 Ethernet standard does not address fiber optic medium. It only includes UTP or shielded UTP mediums.

The statement is false because IEEE 802.3 also includes fiber optic medium

so the answer is false

Hope this is helpful

Please dont downvote the options are correct
