LPI 305-300 Exam - Topic 2 Question 49 Discussion

Actual exam question for LPI's 305-300 exam

Question #: 49
Topic #: 2

[All 305-300 Questions]

Which of the following KVM parameters is identical to the KVM parameter -hdb file.img?

A-drive bus=ide1,type=slave,image=file.img

B-drive type=loop,src=file.img,dst=disk:hdb

D-drive file=file.img,index=1,media=disk,if=ide

C-drive image=file.img,if=ide,device=hdb

E-drive bus=hd,busid=b,src=file.img

Show Suggested Answer

Suggested Answer: D

In QEMU/KVM, the legacy parameter -hdb file.img attaches a disk image as the primary IDE slave device. According to QEMU documentation, this corresponds to an IDE device with index 1, media type disk, and interface IDE.

The modern equivalent using the -drive syntax is:

-drive file=file.img,index=1,media=disk,if=ide

Option D matches this mapping precisely. The other options use invalid or unsupported parameter combinations and do not correctly represent the IDE device mapping.

Therefore, the correct answer is D.

I thought it was -hda instead of -hdb.

I thought -hdb was specifically for the second hard disk, but I’m not confident about what the exact equivalent parameter is.

I encountered a similar question about KVM parameters in my study materials, but I can't remember if -drive is the right answer here.

I remember practicing with KVM parameters, and I feel like -hdb is just a shorthand for something else, but I can't recall the exact equivalent.

Ugh, I'm not sure about this. KVM parameters can be so confusing sometimes. I'll have to guess and hope I get it right.

I'm pretty confident I know the answer to this one. The parameter that's identical to -hdb file.img is probably -drive file=file.img,if=ide or something similar.

Okay, let me think this through. I know KVM has a lot of different parameters, so I'll need to carefully compare them to find the match.
