2V0-21.23 Question 101
Single answerAn administrator is configuring a new ESXi host and needs to decide whether to use BIOS or UEFI firmware. The environment requires secure boot capabilities, faster boot times, and support for larger boot drives. Which firmware should the administrator choose, and why?
- A
BIOS, because it is compatible with secure boot and supports larger boot drives.
- B
BIOS, because it offers faster boot times and is the standard for virtualization environments.
- C
UEFI, because it supports secure boot, faster boot times, and larger boot drives.
- D
UEFI, because it is the legacy option and provides better compatibility with older systems.
Show answer and explanation
Correct answer: C
Explanation
UEFI firmware provides several advantages over BIOS, including support for secure boot, faster boot times, and the ability to handle larger boot drives. These features are essential for modern virtualization environments like those using VMware ESXi. BIOS, on the other hand, is an older and more limited firmware option, making UEFI the better choice in this scenario.
- A. Incorrect.
BIOS does not support secure boot and is limited in its ability to work with larger boot drives. It is an older technology with fewer modern features.
- B. Incorrect.
BIOS does not offer faster boot times compared to UEFI. UEFI is designed for modern systems and offers significant improvements over BIOS.
- C. Correct.
UEFI is the correct answer because it supports secure boot, faster boot times, and larger boot drives, making it more suitable for modern virtualization environments.
- D. Incorrect.
UEFI is not considered a legacy option. It is designed to replace BIOS and provides advanced features for modern systems.
