Exam 220-1101 topic 1 question 486 discussion

To meet the requirements of a rating higher than 50Mbps and minimal range to avoid interference with other access points in the company break room, the technician should select: A. ac Explanation: The 802.11ac standard provides high data rates and improved performance compared to other 802.11 standards. 802.11ac operates in the 5GHz frequency band and supports wider channels, resulting in higher throughput. It is designed to handle high-speed data transfers and is suitable for environments with high data requirements.

802.11b: Operates at 2.4 GHz with a maximum speed of 11 Mbps, which is too slow for the required 50 Mbps. 802.11g: Operates at 2.4 GHz with a maximum speed of 54 Mbps, which meets the speed requirement but may still experience interference from other devices operating in the same frequency band. 802.11n: Operates on both 2.4 GHz and 5 GHz with speeds up to 600 Mbps, which exceeds the 50 Mbps requirement but tends to have a longer range, which might cause interference in crowded environments. 802.11ac: Operates on 5 GHz with speeds up to several Gbps, making it the ideal choice for high-speed connections and minimizing interference due to its targeted range on the 5 GHz band.

C Ac stands for 802.11ac, which is a wireless networking standard that operates in the 5 GHz frequency band and offers a maximum data rate of 1.3 Gbps. 802.11ac is also backward compatible with 802.11a, 802.11b, 802.11g, and 802.11n standards. If a technician wants to install a WAP (wireless access point) in the company break room that has a rating of higher than 50 Mbps and minimal range to avoid interference with other access points, they should select the 802.11ac standard.

802.11ac: Supports speeds significantly higher than 50Mbps and operates in the 5GHz band, with broader coverage. Not the best choice if interference and minimal range are concerns.

The answer is A. 802.11ac provides shorter range and less interference.

It should be C. IMO. C. g Explanation: To meet the requirements of having a rating higher than 50 Mbps and minimal range to avoid interference with other access points, the 802.11g standard is appropriate: 802.11g operates at 2.4 GHz and has a maximum theoretical speed of 54 Mbps, which meets the requirement of being higher than 50 Mbps. 802.11g also has a shorter range compared to some other standards like 802.11n and 802.11ac, which helps in minimizing interference with other access points. Analysis of Other Options: A. ac: 802.11ac operates primarily at 5 GHz with much higher speeds, well over 1 Gbps in ideal conditions. While it exceeds the speed requirement, its range can be longer, and it's more suited for environments needing high throughput, potentially causing more interference. B. b: 802.11b operates at 2.4 GHz with a maximum theoretical speed of 11 Mbps, which is below the required 50 Mbps. D. n: 802.11n can operate at both 2.4 GHz and 5 GHz, with speeds up to 600 Mbps. While it meets the speed requirement, it typically has a longer range, which might not be ideal if the goal is to avoid interference with other access points.
