I don't think D is correct either, since browsers definitely have a way to validate TLS certificates, right?

I feel like option A is wrong because private keys shouldn't be in the browser, but I can't recall the exact details.

I remember practicing a question about how browsers validate certificates, and I think it was about public keys being stored in the browser.

I think the browser uses public keys from CAs to validate TLS certificates, but I'm not entirely sure if it's just the public key or something else.

This is a good question to test our understanding of TLS certificate validation. I'm pretty confident the browser uses the public keys of the CAs, not the private keys. I'll mark option B as my answer.

I'm a bit confused on this one. I know the browser has some way to validate the certificate, but I'm not sure if it's using the public or private keys. I'll have to review my notes on this.

Okay, I've got this. The browser uses the public keys of the CAs to verify the TLS certificate, not the private keys. Option B is the correct answer.

Ah, I see what they're asking for. Option A looks like the best choice - using a variable for the account number in the selector should do the trick.

Okay, let's see. CEF is the Common Event Format, which is a widely used open standard. IIS and W3C are more specific to Microsoft web servers. TLA doesn't ring a bell, so I'm going to rule that one out. I think CEF is the best choice here.

Hmm, I'm a bit unsure about this one. The question is asking what the project manager should do, but the options don't seem directly related to that. I might need to think through the agile principles and the product owner's needs to determine the best approach.

I'm glad the browser doesn't have to carry around the private keys of all CAs. That would be a lot of baggage!

Option D is clearly wrong. The browser definitely has a mechanism to validate TLS certificates, otherwise the whole internet would be a security nightmare.
