220-1101 Wireless Networking Technologies Practice Question
This 220-1201 practice question tests your understanding of wireless networking technologies. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 customer reports that their wireless printer stops responding when the microwave is in use. The printer is connected via Wi-Fi to a dual-band router. Which troubleshooting step should the technician take first to resolve this issue?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Connect the printer to the 5 GHz network
Microwaves emit strong interference on the 2.4 GHz band. Moving the printer to the 5 GHz band avoids that interference. Changing the channel on 2.4 GHz may help but is less effective. Replacing the router or printer is unnecessary.
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 printer with a wired model
Why it's wrong here
This is an expensive and unnecessary solution when a simple configuration change may fix the issue.
✗
Change the router’s 2.4 GHz channel
Why it's wrong here
Changing channels might reduce interference but microwaves often affect the entire 2.4 GHz band, so it may not fully solve the problem.
✓
Connect the printer to the 5 GHz network
Why this is correct
5 GHz is not affected by microwave interference, so moving the printer to that band will stop the disconnections.
Clue confirmation
The clue word "first" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Update the printer firmware
Why it's wrong here
Firmware updates are unlikely to fix interference from a microwave; the issue is physical, not software-related.
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.
