350-401 Question 31
Select 3An enterprise network is preparing to deploy a new wireless network in a large office building. The building will host around 500 employees, with a high density of client devices such as laptops, smartphones, and tablets in shared workspaces. Which of the following considerations are most critical for ensuring optimal performance in a high client density environment?
- A
Deploying access points that support MU-MIMO and OFDMA technologies
- B
Reducing the transmit power of access points to avoid excessive overlap and interference
- C
Using a single SSID for the entire building to simplify client roaming
- D
Implementing band steering to encourage clients to use the 5 GHz band
- E
Placing access points only in areas with the highest user density to minimize costs
Show answer and explanation
Correct answers: A, B, D
Explanation
In high client density environments, it is essential to use modern wireless technologies like MU-MIMO and OFDMA to handle multiple simultaneous connections effectively. Reducing transmit power helps minimize interference caused by overlapping coverage areas, while band steering ensures more optimal use of available wireless spectrum by encouraging devices to connect to the 5 GHz band. Proper planning and design are critical to ensure consistent coverage and performance across the entire deployment area.
- A. Correct.
This is correct. MU-MIMO and OFDMA technologies are critical in high-density environments as they allow access points to handle multiple client devices more efficiently, improving overall performance.
- B. Correct.
This is correct. Reducing transmit power can prevent excessive overlap of wireless coverage and mitigate co-channel interference, which is crucial in high-density deployments.
- C. Incorrect.
This is incorrect. While a single SSID may simplify roaming, in high-density environments, it is often better to implement multiple SSIDs or advanced wireless controllers to manage device load efficiently.
- D. Correct.
This is correct. Band steering encourages devices to connect to the less congested 5 GHz band, which typically has more channels and less interference compared to the 2.4 GHz band.
- E. Incorrect.
This is incorrect. Placing access points only in high-density areas without proper planning can lead to coverage gaps and uneven performance across the network.
