CompTIA A+ Core 1 (220-1001) — Question 375

Ann, a user, needs to attend several day-long conferences and wants to ensure her mobile device will have enough power for these events. She is concerned about wall outlet availability at the conferences and needs to continuously use her device for important updates.
Which of the following should a technician recommend to BEST accommodate Ann's needs?

Answer options

Correct answer: B

Explanation

The built-in battery case is the most effective solution as it provides additional power directly integrated into the device, ensuring Ann can use her phone throughout the conferences. Wireless charging pads and extra charging cords depend on available outlets, which may be limited, while airplane mode would reduce the device's functionality and not address the power issue.
