CompTIA Network+ (N10-007) — Question 558

A technician recently installed a new home router for a customer. The WiFi password was only applied to devices that were locked down with parental controls.
The day after the installation, the customer reported the connection had become slow. The technician reviewed the logs, which indicated a large influx of video streaming. After the customer changed the WiFi password, the streaming stopped, and the performance returned to normal. However, later that night, the same connection slowdown occurred. Which of the following should the technician recommend to the customer to fix this issue? (Choose two.)

Answer options

• A. Upgrade the firmware.
• B. Change the default credentials.
• C. Generate a new key pair.
• D. Use complex passwords.
• E. Turn off port forwarding.
• F. Install an IDS.
• G. Add a WAP.

Correct answer: B, D

Explanation

The correct answers, B and D, focus on enhancing security to prevent unauthorized access that could lead to bandwidth issues. Changing the default credentials (B) helps to secure the router against unauthorized users, while using complex passwords (D) further strengthens access control. The other options do not directly address the issue of unauthorized access or password security.
