Implementing Cisco Wireless Network Fundamentals (WIFUND, legacy) — Question 5

Which two are considered as characteristics of the original 802.11 protocol? (Choose two.)

Answer options

• A. The most common deployment is three non-overlapping channels that are 20 MHz wide.
• B. Defined FHSS and OFDM as possible methods for modulation.
• C. The most common deployment is 6 non-overlapping channels that are 20 MHz wide.
• D. Designed to operate in the 5 GHz ISM frequency spectrum.
• E. Defined DSSS and FHSS as possible methods for modulation.

Correct answer: A, B

Explanation

The correct answers are A and B because the original 802.11 protocol utilized three non-overlapping channels of 20 MHz and included FHSS and OFDM as modulation techniques. Option C is incorrect as it mentions six channels, which is not characteristic of the original protocol, while D refers to the 5 GHz band, which was not part of the original 802.11 specifications. Option E is also incorrect since it does not accurately reflect the modulation methods defined in the original 802.11 protocol.
