CompTIA A+ Core 1 (220-1001) — Question 415

A user is unable to access any LAN resources, such as network shares or printers, but is able to surf the Internet. Which of the following troubleshooting steps should a technician perform FIRST?

Answer options

• A. Inquire about infrastructure changes.
• B. Perform a complete system backup.
• C. Document findings and actions.
• D. Establish a theory of probable cause.

Correct answer: A

Explanation

The correct answer is A because inquiring about infrastructure changes can reveal if there have been any recent modifications that might have affected LAN access. The other options, such as performing a backup or documenting findings, are not immediate troubleshooting steps that address the user's connectivity issue.
