LPI 305-300 Exam - Topic 2 Question 57 Discussion

Actual exam question for LPI's 305-300 exam

Question #: 57
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

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

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

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.

A seems off. Slave type doesn’t match hdb.

I’m leaning towards B. It’s a loop device, but still relevant.

I’m a bit confused about the differences between the options. I remember something about bus and device types, but I can't recall which one matches -hdb exactly.

I practiced a similar question where the parameters were about disk images. I think option D could be the right one since it specifies 'index=1'.

I’m not entirely sure, but I feel like option C sounds familiar since it mentions 'if=ide' which could be relevant.

I think I remember that -hdb refers to the second hard disk, so it might be related to the IDE configuration.
