CompTIA A+ Core 1 (220-1201) — Question 170

An office is experiencing frequent wireless outages and slow network speeds. A technician confirms that all wireless devices are experiencing the same symptoms. Which of the following should the technician do to determine whether the issue is external or internal?

Answer options

• A. Restart all devices and ensure they join the workgroup.
• B. Check the DNS configuration to make sure it is correct.
• C. Connect a machine using Ethernet and test connectivity.
• D. Perform a policy update on Active Directory and reset network settings.

Correct answer: C

Explanation

Connecting a machine using Ethernet and testing connectivity helps to isolate the issue by determining if the network problem is related to the wireless infrastructure or if it is a broader network issue. The other options do not effectively differentiate between external and internal causes of the wireless problems.
