Yeah, DNS is the right answer, no doubt about it!

Wait, isn't DHCP involved in assigning IPs too?

It's definitely DNS that resolves domain names to IPs.

I thought ARP was for local network resolution, not DNS.

I keep mixing up DHCP and DNS. I think DHCP is for assigning IP addresses, but I’m not 100% sure.

I practiced a similar question where DNS was definitely the protocol for resolving URLs. I’m leaning towards that.

I’m not entirely sure, but I remember something about SMTP being related to email, so it can’t be the right choice here.

I think the answer is DNS because it’s used for resolving domain names to IP addresses, right?

This is a good test of our understanding of how the web works under the hood. I think the key here is to focus on the specific step of resolving the domain name to an IP address, which is the job of the DNS protocol. So I'm confident that A is the correct answer.

I'm a little confused by this question. I know there are different protocols involved in web browsing, like HTTP, TCP/IP, and so on. Is DNS the only one relevant here, or are there other factors I should be considering? I'll have to review my networking concepts before answering.

Okay, let me walk through this step-by-step. When you enter a URL in a web browser, the browser first needs to resolve the domain name (www.cisco.com) to an IP address. That's where DNS comes in, so I'm going with option A.

Hmm, I'm a bit unsure about this one. I know DNS is used for domain name resolution, but I'm not sure if that's the only protocol involved in the process of accessing a website. I'll have to think this through carefully.

This seems like a straightforward networking question. I'm pretty confident the answer is DNS, since that's the protocol used to resolve domain names to IP addresses.

Hmm, let me think... DNS, of course! Unless, of course, the answer is actually 42. You know, the answer to the ultimate question of life, the universe, and everything.

DNS all the way, baby! If it wasn't for that protocol, we'd be typing in IP addresses like it's the 90s. Ain't nobody got time for that!

DHCP? Really? I thought that was for dynamic IP assignment, not domain name resolution. Someone needs to go back to Networking 101.

No, SMTP is used for email communication, not for resolving domain names.

Ah, the age-old question of how the internet works. I'll go with DNS on this one. It's the backbone of the web, you know.

I'm not sure, but I think it's A) DNS too. It makes sense that it would be used for resolving domain names.

I agree with Julian. DNS is used to translate domain names like www.cisco.com into IP addresses.

DNS, of course! That's the protocol responsible for mapping domain names to IP addresses. How else would the browser find the website?

Without DNS, the browser wouldn't know where to find the website.
