CompTIA A+ Core 2 (220-1102) — Question 15

A homeowner recently moved and requires a new router for the new ISP to function correctly. The internet service has been installed and has been confirmed as functional. Which of the following is the FIRST step the homeowner should take after installation of all relevant cabling and hardware?

Answer options

• A. Convert the PC from a DHCP assignment to a static IP address.
• B. Run a speed test to ensure the advertised speeds are met
• C. Test all network sharing and printing functionality the customer uses.
• D. Change the default passwords on new network devices.

Correct answer: D

Explanation

The correct answer is D because changing default passwords is a critical step in securing the network against unauthorized access. Options A, B, and C are important tasks but they do not address the immediate security concern after installation.
