CompTIA A+ Core 1 (220-1001) — Question 302

A technician is using PXE to upgrade the OS in a lab that has new and old computers. The new devices can obtain a DHCP address but fail to locate the PXE server. The old computers can locate the PXE server and upgrade the OS as required. Which of the following is MOST likely preventing the new computers from booting to PXE?

Answer options

• A. LoJack security
• B. BIOS password
• C. Drive encryption
• D. Secure Boot

Correct answer: D

Explanation

The new computers are likely prevented from booting to PXE due to Secure Boot, which is designed to ensure that only trusted software is loaded during the boot process. The older computers do not have this restriction, allowing them to access the PXE server without issue. The other options, such as LoJack security, BIOS password, and drive encryption, do not directly affect the ability to locate or boot from the PXE server.
