CompTIA A+ Core 2 (220-1102) — Question 555

A user takes a work-issued laptop home for the first time. When the user attempts to browse any website on the home internet, the user receives the following error:

"This site cannot be reached."

A technician from work confirms that the static IP that was set up on the machine was changed back to DHCP. Which of the following needs to be corrected?

Answer options

• A. HTTPS
• B. VLAN
• C. DNS
• D. SMTP

Correct answer: C

Explanation

The correct answer is C, as DNS (Domain Name System) settings may not be configured properly after switching from a static IP to DHCP, leading to the inability to resolve website addresses. Options A (HTTPS), B (VLAN), and D (SMTP) are unrelated to the issue of accessing websites and would not resolve the connectivity problem.
