Yeah, "P" is definitely linked to crypto activities.

Wait, are we sure it's not "I"? Sounds off.

"C" is the one to watch for crypto mining!

Definitely keep an eye on the "P" instances.

I definitely recall that "I" is related to instances, but I can't remember if it's the one for crypto mining.

I’m a bit confused; I thought it was "P" for potential crypto mining, but now I’m second-guessing myself.

I remember practicing a question about EC2 instances, and I feel like "R" was mentioned in that context.

I think the prefix we need to monitor is "C," but I'm not entirely sure if that's right.

I'm pretty confident the answer is "R" for Spot instances. Crypto miners often try to leverage cheaper Spot instances, so that's the one I'll go with.

Okay, let's see. I know crypto mining often uses powerful GPU-based instances, so I'm guessing the "P" prefix for GPU-optimized instances might be the one to monitor.

Hmm, this seems like a tricky one. I'll need to think carefully about the different EC2 instance prefixes and which one might be associated with crypto mining.

I'm a bit unsure about this one. I'll need to review my notes on EC2 instance types and security best practices to try to figure this out.

Okay, the key here is understanding the system's support for manual switchover between primary and read-only nodes. I think I can work this out.

I wonder if we can create a new instance type called 'DOGE' for all my fellow crypto enthusiasts out there.

The answer is clearly 'P' - it stands for 'Profit', which is what the crypto miners are after, am I right?

Yes, 'P' definitely stands for profit, which is the main goal of crypto miners.

I think the answer is 'P' as well, it makes sense that they would target profit.

No, it's actually 'C'. That's the Amazon EC2 instance prefix to monitor for potential crypto mining.

I disagree, I believe the answer is D because I read that those instances are more likely to be targeted for crypto mining.
