CompTIA A+ Core 1 (220-1001) — Question 358

A user is unable to access network resources on a laptop. A technician examines the device and attempts to reproduce the issue. The technician cannot connect to resources by name or IP. Which of the following should the technician check FIRST?

Answer options

• A. AP power levels
• B. DNS server availability
• C. Upstream router WAN IP
• D. Wireless button state

Correct answer: B

Explanation

The technician should check the DNS server availability first because DNS is crucial for resolving hostnames to IP addresses, which is necessary for accessing network resources. If the DNS server is down, the laptop won't be able to connect to resources by name, and if there are IP connectivity issues, resolving hostnames won't help. The other options, while potentially relevant, are not the primary concern at this stage.
