CompTIA SK0-005 Exam - Topic 1 Question 78 Discussion

Actual exam question for CompTIA's SK0-005 exam

Question #: 78
Topic #: 1

A storage administrator is configuring a new array to provide storage to a virtual cluster. The array has a built-in backup agent to allow data that is stored on the array to be backed up. The storage administrator wants the virtual cluster to use a file-based storage protocol so the backup agent can just back up the files that change and not the whole data store. Which of the following storage protocols should the administrator use?

AiSCSI

BFC

CFCoE

DNFS

Show Suggested Answer

Suggested Answer: D

Different storage protocols operate at different levels (file-based vs. block-based):

iSCSI (Internet Small Computer Systems Interface) is a block-level protocol, meaning that the storage appears as raw disk space to the operating system. Backups would require copying entire blocks, rather than specific files.

FC (Fibre Channel) is another block-level protocol used in high-performance SANs. It does not support file-based storage natively.

FCoE (Fibre Channel over Ethernet) extends FC over Ethernet but still functions as a block-based storage solution.

NFS (Network File System) is a file-based storage protocol, making it the best option. It allows direct access to files, which enables backup software to back up only modified files instead of the entire block device.

Since the administrator requires a file-based storage protocol to ensure efficient incremental backups, NFS is the correct choice.

Wait, isn't iSCSI also a good option?

Not sure if NFS is the best choice, what about performance issues?

I thought FC was more efficient for backups, but NFS makes sense here.

I thought FCoE was more for converged networks, so it can't be that. NFS seems like the best fit for file-based access.

I feel like NFS is the right choice here, but I keep mixing it up with SMB sometimes.

I remember practicing a question about storage protocols, and I think iSCSI was more block-based, so it probably wouldn't work for this scenario.

I think the answer might be NFS since it's file-based, but I'm not completely sure.

I'm a bit confused on this one. I know the backup agent is important, but I'm not sure how that factors into the choice of storage protocol. I'll have to think about this a bit more.

I'm confident that the answer is NFS. It's a file-based protocol, which should work well with the backup agent's ability to back up only the changed files.

Okay, let me think this through. The virtual cluster needs a file-based storage protocol, and the backup agent can back up the files that change. I think NFS would be the best choice here.

Hmm, I'm a bit unsure about this one. I know the backup agent needs to work with the storage protocol, but I'm not sure which one would be the best fit.

This seems like a straightforward question. The key is to identify the storage protocol that allows for file-based backups.

NFS is the answer, no doubt about it. I'm picturing the storage admin doing a little dance of joy when they realize they don't have to back up the whole data store. Efficiency FTW!

Option D, NFS, is the obvious answer. Who wants to back up an entire data store when you can just focus on the files that have changed? Sign me up for NFS!

I'd go with NFS too. File-based storage is the key requirement here, and NFS is a solid choice for that. Gotta love when the backup process can be streamlined.

NFS sounds like the way to go. That way the backup agent can easily target the files that have changed instead of the whole data store. Seems like the most efficient solution.
