CompTIA A+ 220-1102 Practice Question

Investigate installed browser extensions for any that appear suspicious or unnecessary - This is correct. Malicious or unnecessary browser extensions are a common cause of frequent pop-ups and redirects. Identifying and removing suspicious extensions can directly address the root cause of the issue.

Clear the browser's cache and cookies to eliminate stored data - Clearing the cache and cookies can resolve some browsing issues, but it is unlikely to stop pop-ups and redirects caused by malicious extensions or malware.

Disable JavaScript in the browser settings to reduce pop-ups - Disabling JavaScript can reduce some pop-ups, but it may also break the functionality of many legitimate websites. This is not a practical or targeted solution for troubleshooting this issue.

Update the browser to the latest version to ensure security patches are applied - Updating the browser is good practice for overall security but is unlikely to resolve the specific issue of pop-ups and redirects caused by malicious extensions or adware.
