350-401 Question 160
Select 3A network engineer is tasked with designing a wireless network for a corporate office. The network must support high-density environments such as conference rooms and auditoriums while minimizing interference from neighboring access points. Which combination of strategies should the engineer implement to optimize wireless performance?
- A
Enable Dynamic Channel Assignment (DCA) to manage channel selection automatically.
- B
Configure all access points to use the same channel to simplify deployment.
- C
Reduce the transmit power of access points in high-density areas to limit coverage overlap.
- D
Utilize 80 MHz channel widths to maximize throughput across all access points.
- E
Enable band steering to move compatible client devices to the 5 GHz band.
Show answer and explanation
Correct answers: A, C, E
Explanation
High-density wireless environments require careful planning to reduce interference and maximize performance. Dynamic Channel Assignment (DCA) ensures optimal channel selection, transmit power adjustments reduce overlap and interference, and band steering helps balance the load across frequency bands. Configuring all access points on the same channel or using wide channel widths would increase interference and degrade network performance.
- A. Correct.
Dynamic Channel Assignment (DCA) automatically selects the optimal channel for each access point, reducing co-channel interference in high-density environments.
- B. Incorrect.
Configuring all access points to use the same channel will lead to significant interference and is not recommended in high-density scenarios.
- C. Correct.
Reducing transmit power helps to minimize coverage overlap and interference between access points, which is crucial in high-density environments.
- D. Incorrect.
While 80 MHz channel widths can increase throughput, they reduce the number of non-overlapping channels available, which can lead to interference in high-density deployments.
- E. Correct.
Band steering encourages devices capable of using the 5 GHz band to connect there, reducing congestion on the 2.4 GHz band and improving overall performance.
