220-1201 Practice Question: A company deploys a new 802.11ac access point in…
A company deploys a new 802.11ac access point in a warehouse. After installation, workers report that their handheld scanners frequently disconnect when moving between aisles. The AP is mounted on a high ceiling. Which configuration change would most likely improve connectivity?
⚠ Common exam trap
A common trap is to assume that 5 GHz always outperforms 2.4 GHz, but in warehouse environments with many obstacles, 2.4 GHz offers better range and penetration.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Change the AP to use only 2.4 GHz band.
The 5 GHz band used by 802.11ac has poorer penetration and range through obstacles like warehouse shelving and inventory. By switching to the 2.4 GHz band, signals diffract better around aisles and through racks, reducing disconnections for mobile scanners moving between aisles.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Change the AP to use only 2.4 GHz band.
Why this is correct
2.4 GHz has better range and can penetrate obstacles like warehouse racks more effectively, reducing disconnects.
- ✗
Increase the AP's channel width to 80 MHz.
Why it's wrong here
Wider channels increase throughput but reduce range and are more susceptible to interference, worsening the issue.
- ✗
Enable WPA3 encryption on the network.
Why it's wrong here
Encryption does not affect range or signal penetration; it only secures data.
- ✗
Reduce the AP's transmit power to avoid interference.
Why it's wrong here
Lowering power would reduce range, making disconnects more likely.
