220-1201 Practice Question: Deploying a new branch office in a location where…
A company is deploying a new branch office in a location where no wired internet is available. They need a reliable connection with moderate speed and low latency for VoIP and video conferencing. Which technology should they consider?
⚠ Common exam trap
CompTIA A+ often tests the misconception that satellite internet is suitable for real-time communications, but the trap here is that candidates overlook the critical latency difference between satellite and fixed wireless, assuming any wireless option is equivalent.
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
✓
Fixed wireless (e.g., point-to-point microwave)
Fixed wireless (point-to-point microwave) provides a dedicated, low-latency link ideal for real-time applications like VoIP and video conferencing. Unlike satellite, it avoids the high latency (500-800 ms) caused by geostationary orbits, and unlike cellular, it offers consistent bandwidth without contention from other users in the area.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Satellite internet
Why it's wrong here
Satellite has high latency (600+ ms), which is unsuitable for real-time VoIP and video conferencing.
- ✓
Fixed wireless (e.g., point-to-point microwave)
Why this is correct
Fixed wireless can provide low latency and reliable speeds suitable for VoIP and video, especially with line-of-sight.
- ✗
Cellular 4G/5G hotspot
Why it's wrong here
Cellular can have variable latency and may be subject to congestion, though it could be a secondary option.
- ✗
Dial-up
Why it's wrong here
Dial-up is too slow (56 Kbps) and has high latency, making it unusable for modern VoIP and video.
