質問 # 10
Which of the following utilizes specialized ports on a laptop to expand the local connection options?

質問 # 11
Which of the following can be used by a mobile device to access a secure building?
正解：B
解説：
The correct answer is B. Near-field communication (NFC).
According to the CompTIA A+ Core 1 220-1201 objectives under Mobile Devices and Security:
* NFC is commonly used for secure access control. Many organizations implement NFC-enabled ID badges or mobile devices to unlock doors, gates, or secure areas.
* The mobile device communicates over a very short range (a few centimeters) with a reader to authenticate the user.
Why the other options are incorrect:
* A. Hotspot: Provides internet access, not physical building access.
* C. Infrared scanner: While used in some legacy devices, it is not commonly implemented for secure mobile access.
* D. Geolocation: Can provide location awareness but does not grant direct access to secure physical spaces.
