Which of the following can be hot-swappable?
- A.
Hard drive
- B.
Tape drive
- C.
Floppy drive
- D.
DVD-RW
Correct Answer
A. Hard driveExplanation
A hard drive can be hot-swappable, meaning it can be replaced or removed while the system is still running without causing any damage or interruption. This is because hard drives are designed to be easily removable and replaceable, allowing for convenient upgrades or maintenance without the need to shut down the entire system. On the other hand, tape drives, floppy drives, and DVD-RW drives are not typically hot-swappable as they require manual intervention and system shutdown to be replaced or removed safely.Rate this question:

Which of the following wireless security techniques is the MOST secure?
- A.
Enable Wired Equivalent Privacy
- B.
Disable SSID broadcast
- C.
Enable Wi-Fi Protected Access
- D.
Enable MAC filtering
Correct Answer
C. Enable Wi-Fi Protected AccessExplanation
Wi-Fi Protected Access (WPA) is the most secure wireless security technique among the given options. WPA provides stronger encryption and authentication methods compared to Wired Equivalent Privacy (WEP) and SSID broadcast disabling. WPA uses Temporal Key Integrity Protocol (TKIP) or Advanced Encryption Standard (AES) encryption to protect data transmission. It also supports authentication through the use of a pre-shared key or an enterprise authentication server. MAC filtering, while providing an additional layer of security, can be bypassed by skilled attackers. Therefore, enabling WPA is the best choice for ensuring the highest level of wireless security.Rate this question:
