CompTIA A+ Core 2 (220-1102) — Question 173

A technician is editing the hosts file on a few PCs in order to block certain domains. Which of the following would the technician need to execute after editing the hosts file?

Answer options

• A. Enable promiscuous mode.
• B. Clear the browser cache.
• C. Add a new network adapter.
• D. Reset the network adapter.

Correct answer: B

Explanation

The correct answer is B, as clearing the browser cache is necessary to ensure that the browser does not load any cached versions of the domains that are meant to be blocked. The other options do not relate directly to the changes made in the hosts file or are not relevant to the immediate action required after the edit.
