FC0-U71 Tech Concepts and Terminology Practice Question
A technician is configuring a wireless access point for a small office. The office has several older laptops that only support the 2.4 GHz frequency band, as well as newer devices that support both 2.4 GHz and 5 GHz. The technician wants to ensure all devices can connect while minimizing interference. Which of the following should the technician do?
⚠ Common exam trap
The trap here is assuming that using the same SSID for both bands will automatically steer devices to the best band, but many devices do not support band steering effectively.
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
✓
Enable both 2.4 GHz and 5 GHz bands with separate SSIDs.
To support both older and newer devices while minimizing interference, the technician should enable both bands with separate SSIDs. This allows older devices to use 2.4 GHz and newer devices to use 5 GHz, reducing congestion and improving performance. Other options either exclude some devices or fail to optimize band usage.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable both bands with the same SSID.
Why it's wrong here
Using the same SSID for both bands can cause devices to connect to the slower 2.4 GHz band even when 5 GHz is available, due to band steering limitations. This may lead to suboptimal performance and does not guarantee that newer devices use the faster band. Separate SSIDs provide more control.
- ✗
Enable only the 5 GHz band.
Why it's wrong here
Older laptops that only support 2.4 GHz would be unable to connect if only 5 GHz is enabled. This would leave some users without wireless access. Therefore, this option fails to meet the requirement of supporting all devices.
- ✗
Enable only the 2.4 GHz band.
Why it's wrong here
While all devices could connect to 2.4 GHz, this band is more prone to interference and offers lower speeds. Newer devices would not benefit from the faster 5 GHz band. This does not minimize interference or optimize performance for capable devices.
- ✓
Enable both 2.4 GHz and 5 GHz bands with separate SSIDs.
Why this is correct
Enabling both bands with separate SSIDs allows older devices to connect to the 2.4 GHz network and newer devices to use the faster, less congested 5 GHz band. This setup maximizes compatibility and performance while reducing interference for devices that can use 5 GHz. It is a common best practice in mixed-device environments.
