The answer is to check the ATA’s configuration to ensure T.38 fax relay is enabled. This is correct because fax over VoIP is highly sensitive to jitter and latency; without T.38, the ATA will use voice codecs that compress the fax audio, corrupting the data and causing incomplete or failed transmissions. T.38 is a protocol specifically designed to convert fax signals into digital packets that can traverse VoIP networks reliably, bypassing the problematic voice compression. On the CompTIA A+ Core 1 220-1201 exam, this question tests your understanding of VoIP troubleshooting and the role of an analog telephone adapter in a mixed analog-digital environment. A common trap is to immediately blame the multifunction printer or network bandwidth, but the ATA’s fax passthrough settings are the first logical check. Memory tip: think “T.38 = Fax’s 38th parallel”—it keeps fax data on a separate, uncompressed path to avoid distortion.
220-1101 Multifunction Devices Practice Question
This 220-1201 practice question tests your understanding of multifunction devices. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company's multifunction printer supports faxing over VoIP. Users report that faxes are frequently incomplete or fail to send. The fax line is connected to an analog telephone adapter (ATA). What should you check first?

Correct answer & explanation
✓
Check the ATA's configuration to ensure T.38 fax relay is enabled.
Fax over VoIP is sensitive to jitter and latency. The ATA's settings for fax passthrough (T.38) must be enabled and properly configured. Without T.38, fax data may be corrupted by voice codecs.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Replace the fax modem card in the printer.
Why it's wrong here
The issue is likely network-related, not hardware failure.
✓
Check the ATA's configuration to ensure T.38 fax relay is enabled.
Why this is correct
T.38 is the standard for fax over IP; without it, faxes fail over VoIP.
Clue confirmation
The clue word "first" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Increase the printer's print resolution.
Why it's wrong here
Print resolution does not affect fax transmission.
✗
Disable the printer's firewall.
Why it's wrong here
The printer's firewall is unlikely to affect fax over the analog line.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 220-1201 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
