2V0-21.23 Question 248
Select 2A vSphere administrator is setting up an ESXi host and needs to configure the boot options to ensure compatibility with a UEFI-based server. Which of the following boot options are appropriate for this setup?
- A
Legacy BIOS boot mode
- B
UEFI Secure Boot
- C
Boot from SAN using iSCSI
- D
PXE Boot with UEFI
Show answer and explanation
Correct answers: B, D
Explanation
When configuring an ESXi host on a UEFI-based server, UEFI Secure Boot and PXE Boot with UEFI are appropriate options. UEFI Secure Boot ensures a secure boot process, while PXE Boot with UEFI provides network-based boot capabilities compatible with UEFI firmware. Legacy BIOS boot mode is incompatible with UEFI, and booting from SAN using iSCSI is unrelated to the UEFI requirement.
- A. Incorrect.
Legacy BIOS boot mode is not suitable for UEFI-based servers as it uses an older BIOS standard and lacks the features of UEFI.
- B. Correct.
UEFI Secure Boot is a valid option for UEFI-based servers, providing enhanced security during the boot process by verifying digital signatures of boot loaders.
- C. Incorrect.
Boot from SAN using iSCSI is a valid option for booting ESXi, but it is independent of whether the server is UEFI-based or not. Therefore, it is not specific to UEFI compatibility.
- D. Correct.
PXE Boot with UEFI is a valid option for booting ESXi on UEFI-based servers, leveraging the network boot functionality compatible with UEFI firmware.
