Question

Difficulty: MediumWeb Browser Security and Pop-Up/Redirect Troubleshooting

A user on a Windows 11 workstation reports that launching web browsers automatically redirects their sessions to an external ad-supported search engine. Further inspection reveals that entering standard internal and external domain names into the address bar routes requests to unauthorized third-party IP addresses. Which of the following remediation steps should the technician perform to resolve these browser security issues? (Select TWO.)

  1. Inspect the web browser add-on manager and disable or uninstall unrecognized extensions.Answer
  2. B
    Clear the web browser temporary cache and browsing history.
  3. Inspect the local Windows hosts file and delete unauthorized domain-to-IP address mappings.Answer
  4. D
    Rebuild the local search index using the Indexing Options Control Panel applet.

Answer

The technician should inspect the web browser add-on manager to remove unrecognized extensions, and examine the local Windows hosts file to delete unauthorized domain-to-IP mappings.
To completely remediate unwanted browser redirects and forced domain routing, a technician must remove rogue extensions within the browser add-on manager and delete unauthorized domain-to-IP mappings in the operating system's local hosts file.

Step-by-Step Solution

1
Isolate and remove extension-based browser hijackers within the web browser.
Unapproved extensions causing search engine redirection are removed from the browser environment.
Rogue extensions frequently alter default search providers and home page settings.
2
Examine system-level name resolution settings in C:\Windows\System32\drivers\etc\hosts.
Unauthorized static IP entries redirecting web traffic are erased.
Modifications to the local hosts file intercept domain lookup requests before DNS resolution occurs.
