Wait, EC2 instance storage? That doesn't sound durable at all!

Amazon S3 is not the right choice here, right?

I thought ElasticCache was better for low latency?

Definitely DynamoDB for shared data store!

I have a vague memory that S3 is more for object storage, so I don't think it fits this scenario.

I practiced a similar question where we had to choose between DynamoDB and ElasticCache. I think DynamoDB is the better option here.

I'm not entirely sure, but I feel like EC2 instance storage is more temporary and not really a shared data store.

I remember studying about data stores, and I think DynamoDB is designed for low latency and durability.

I'm a little confused by this question. What exactly do they mean by "user state information"? Is that the same as session data? If so, then DynamoDB could be a good choice, but I'm not 100% sure.

Okay, let me think this through. We need a shared data store, so that rules out EC2 instance storage. S3 has durability, but I'm not sure about the latency. DynamoDB does sound like the best option here.

I think this is a pretty straightforward question. The key is that we need a shared data store with durability and low latency, which points to DynamoDB.

Hmm, I'm a bit unsure about this one. I know DynamoDB is a NoSQL database, but I'm not sure if it has the low latency we're looking for. Maybe EC2 instance storage could work?

Hmm, I'm a bit confused on this one. The question mentions AJAX and the user tabbing out of each field, so I'm wondering if the Request scope might also be a valid option since the data is being updated in real-time. I'll need to think this through a bit more carefully.

If this was a test on AWS dad jokes, I'd be acing it. But alas, it's just about databases and stuff. Where's the fun in that?

I'm just hoping the correct answer isn't hidden behind a paywall or something. AWS can be tricky like that, you know?

ElasticCache Memcached could also work for low latency.

Hmm, EC2 instance storage is temporary and not shared, so that's a no-go. I'm torn between A and B, but I'll go with B since S3 is more for object storage.

I was leaning towards D, but then I remembered ElastiCache Memcached is more for caching and not really a durable data store. Good thing I double-checked the options!
