Show Suggested Answer

Suggested Answer: A

When using quotas, administrators have the option to calculate file system usage in one of two ways. This option, which is configured on a per file system basis, may be set to File Size or Block based calculation. When using the default setting of File Size, disk usage is calculated based on logical file sizes in 1K increments. Because of this, it is possible that used space may be reported from a quota perspective as more than the actual usage if holes exist in a sparse file. This setting is generally recommended for Windows environments. The Block quota policy calculates disk usage in 8-16KB file system blocks, and is accurate with regard to the actual allocation down to the block level. This setting is recommended for UNIX environments.

That's true, but I think Tree Quotas could provide a more versatile way of controlling storage usage.

I agree with Lonny, User Quotas would probably be the default to assign limits to individual users.

Hmm, that's a good point. But I still think User Quotas would be the default policy for simplicity.

I believe it's Tree Quotas, as it makes more sense for managing file system usage.

Ouch, Minna. Way to throw some shade! But you're not wrong. If we're going for a storage admin certification, we should probably know our Dell EMC products.

Haha, Hildegarde. If you haven't heard of the Dell EMC Unity XT, you might be in trouble. That's like storage management 101 these days.

Yeah, I agree. This feels like it's testing our specific product knowledge more than our general understanding of file system quotas. Hopefully, I've at least heard of the Dell EMC Unity XT before.

I think it's a fair question. File system quota policies are a pretty fundamental concept in storage management. But the Dell EMC specific part could throw some people off.

Good point, Esteban. I'm not too familiar with the Dell EMC Unity XT, so I'm hoping this isn't too niche of a question.

Hmm, this is an interesting question. I wonder if it's testing our knowledge of Dell EMC Unity XT storage arrays specifically, or just general file system quota policies.
