Pretty sure it's oversubscription, guys.

200 GB on 100 GB? Sounds risky...

That's definitely oversubscription!

I feel like I've seen this term before in my studies. The ratio of virtual to physical memory being greater than one definitely points to oversubscription, right?

I'm a bit confused because I thought overprovisioning was related to allocating more resources than necessary, but I'm not sure if that applies here.

I remember practicing a similar question where we discussed the difference between overprovisioning and oversubscription. I think this one is definitely oversubscription.

I think this question is about how virtual memory can exceed physical memory, which sounds like oversubscription, but I'm not entirely sure.

Okay, I think I've got it. The key here is the ratio of virtual to physical memory. Since the virtual memory is 2x the physical memory, that's a case of oversubscription. I'm going with option C.

Oversubscription, for sure. The virtual memory is double the physical memory, so the cluster is oversubscribed. This is a common practice in virtualized environments to make efficient use of the available resources.

Hmm, I'm a bit confused by this question. The total virtual memory is 200 GB, but the physical memory is only 100 GB. I'm not sure if that's considered "thick provisioning" or something else. I'll have to think about this one.

I think this is asking about the concept of oversubscription, where the total virtual memory allocated to VMs exceeds the physical memory available on the cluster. I'll go with option C.

Oversubscription for the win! This is like asking a fish to identify water - it's just basic virtualization knowledge.

I agree with Keith, the ratio of virtual to physical memory is higher, so it's oversubscription.

Why do they make these questions so confusing? It's obviously Oversubscription. I'm just going to go with my gut on this one.

I think it's Overprovisioning. Allocating more virtual memory than physical memory sounds like the system is being overprovisioned, right?

But with 200 GB virtual memory on 100 GB physical memory, it seems like oversubscription to me.

Oversubscription, for sure! I learned about this in my virtualization class. The virtual memory allocated is more than the physical memory available - that's the definition of oversubscription.
