220-1102 Practice Question: That their web browser is repeatedly opening…
This 220-1102 practice question tests your understanding of that their web browser is repeatedly opening…. 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 user reports that their web browser is repeatedly opening pop-up advertisements on every website visited. The technician has run a full antivirus scan which found no threats. Which of the following should the technician try NEXT?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
Disable browser notifications for suspicious websites
This may reduce some pop-ups but will not remove extensions that generate advertisements.
B
Distractor review
Install a reputable ad-blocking extension
An ad blocker might block the pop-ups, but it does not resolve the root cause (likely a malicious extension).
C
Best answer
Reset the browser settings to their defaults
Resetting the browser removes suspicious extensions, restores default search engine, and clears corrupted settings, effectively eliminating most pop-up issues.
D
Distractor review
Change the browser homepage to a blank page
Changing the homepage only affects the page that opens when the browser starts, not pop-up behavior.
Answer analysis
Why the other options are wrong
Understanding why incorrect options are tempting is as important as knowing the correct answer.
- ✗
Disable browser notifications for suspicious websites
This may reduce some pop-ups but will not remove extensions that generate advertisements.
- ✗
Install a reputable ad-blocking extension
An ad blocker might block the pop-ups, but it does not resolve the root cause (likely a malicious extension).
- ✗
Change the browser homepage to a blank page
Changing the homepage only affects the page that opens when the browser starts, not pop-up behavior.
Common exam trap
Common exam trap: usable hosts are not the same as total addresses
Subnetting questions often tempt you into counting all addresses. In normal IPv4 subnets, the network and broadcast addresses are not usable host addresses.
Technical deep dive
How to think about this question
Subnetting questions test whether you can identify the network, broadcast address, usable range, mask and correct subnet. Slow down enough to calculate the block size correctly.
KKey Concepts to Remember
- CIDR notation defines the prefix length.
- Block size helps identify subnet boundaries.
- Network and broadcast addresses are not usable hosts in normal IPv4 subnets.
- The required host count determines the smallest suitable subnet.
TExam Day Tips
- Write the block size before choosing the subnet.
- Check whether the question asks for hosts, subnets or a specific address range.
- Do not confuse /24, /25, /26 and /27 host counts.
Key takeaway
Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.

FAQ
Questions learners often ask
What does this 220-1102 question test?
CIDR notation defines the prefix length.
What is the correct answer to this question?
The correct answer is: Reset the browser settings to their defaults — Pop-up ads in the browser that appear on every site are often caused by unwanted browser extensions, toolbars, or altered browser settings. Resetting the browser to its default state removes malicious extensions and restores default configuration, which is a quick and effective first step after verifying no malware is present. Disabling notifications may help with some pop-ups, but it will not remove extensions. Installing an ad-block extension may mask the issue but does not remove the underlying cause. Changing the homepage does not affect pop-ups.
What should I do if I get this 220-1102 question wrong?
Review block sizes, usable host formulas (2^n − 2), and how to find network and broadcast addresses for /24 through /30. Then practise related 220-1102 subnetting questions on CIDR, address ranges, and subnet selection.
