I definitely remember that read-only instances are not for data backtracking, so I think C is definitely not applicable here.

I feel like option A makes sense because it could help with write pressure, but I don't remember if that's the right context for read-only instances.

I think RDS read-only instances are mainly used to reduce read pressure on the primary instance, but I'm not entirely sure.

I've got a good strategy for this type of question. I'll first eliminate the options that are clearly incorrect, then focus on the remaining choices and try to determine the best fit. That should help me narrow it down.

I'm a bit confused by this question. The options seem similar, and I'm not sure I fully understand the differences between them. I'll have to review my notes on RDS read-only instances before answering this one.

Okay, let's see here. RDS read-only instances are used to scale out read capacity, so that makes me think the answer is B. But I want to double-check the other options just to be sure.

Hmm, I'm not entirely sure about this one. I know read-only instances are used to offload read traffic, but I'm not confident which specific scenario this question is asking about. I'll have to think it through carefully.

This looks like a straightforward question about the use cases for RDS read-only instances. I think the answer is B - it reduces the read pressure on the primary RDS instance.

Okay, I've got this. The question is asking about a type of malware that takes advantage of a vulnerability, so the answer has to be an exploit. D is the correct choice.

I'm a bit confused on this one. Is option A about creating a separate navigation path for the newer entries? That doesn't seem like the best solution to me. I'd probably lean towards either option B or D, but I'll need to think it through a bit more.

I'm a little confused by this one. I know packages and reports are related, but I'm not sure of the exact relationship between them. Is the default package something that's set at the report level, or is it more of a package-level setting? I'll have to guess on this one, but I'm not super confident.

A lamp seems like more of a shopping product that people would put more thought into purchasing, rather than a convenience product. I'm leaning towards the can of soda or maybe the concert tickets purchased online as the best answers.
