AWS Certified Solutions Architect – Professional — Question 599

Which system is used by Amazon Machine Images paravirtual (PV) virtualization during the boot process?

Answer options

• A. PV-BOOT
• B. PV-AMI
• C. PV-WORM
• D. PV-GRUB

Correct answer: D

Explanation

PV-GRUB is the paravirtual bootloader used by PV Amazon Machine Images to load the kernel specified in the image's menu.lst file. This allows users to run custom kernels instead of being restricted to the default Amazon kernel. The other options, such as PV-BOOT, PV-AMI, and PV-WORM, are not actual boot systems used by AWS.
