Amazon ANS-C01 Exam - Topic 1 Question 53 Discussion

Actual exam question for Amazon's ANS-C01 exam

Question #: 53
Topic #: 1

A company's network engineer is designing a hybrid DNS solution for an AWS Cloud workload. Individual teams want to manage their own DNS hostnames for their applications in their development environment. The solution must integrate the application-specific hostnames with the centrally managed DNS hostnames from the on-premises network and must provide bidirectional name resolution. The solution also must minimize management overhead.

Which combination of steps should the network engineer take to meet these requirements? (Choose three.)

AUse an Amazon Route 53 Resolver inbound endpoint.

BModify the DHCP options set by setting a custom DNS server value.

CUse an Amazon Route 53 Resolver outbound endpoint.

DCreate DNS proxy servers.

ECreate Amazon Route 53 private hosted zones.

FSet up a zone transfer between Amazon Route 53 and the on-premises DNS.

I agree, the outbound endpoint is crucial for bidirectional resolution.

Not sure about the DNS proxy servers, seems unnecessary.

I think using private hosted zones is a must too.

Wait, can you really integrate on-prem DNS like that? Sounds complicated!

Definitely need the Route 53 Resolver inbound endpoint!

I’m a bit confused about whether we need outbound endpoints as well, since I know they help with queries going back to on-premises, but I’m not certain if they’re essential in this case.

I practiced a similar question where we had to set up private hosted zones, and I feel like that might be part of the solution here too.

I think modifying the DHCP options set could help with DNS resolution, but I can't recall if it's necessary for bidirectional name resolution.

I remember that using Route 53 Resolver inbound endpoints is crucial for integrating with on-premises DNS, but I'm not sure if it's the only step needed.

I feel pretty confident about this one. Using Route 53 Resolver endpoints and private hosted zones seems like the way to go to meet all the requirements. I just need to make sure I explain my reasoning clearly.

Whoa, this is a lot to unpack. I'm a bit overwhelmed, but I'll take it step-by-step and try to break down the different components of the solution.

Okay, I think I've got a strategy here. I'll focus on the key requirements - integrating app-specific hostnames, providing bidirectional resolution, and minimizing management overhead. That should help me narrow down the right combination of steps.

Hmm, this seems like a complex setup. I'll need to make sure I understand the difference between inbound and outbound endpoints, and how private hosted zones fit into the picture.

This looks like a tricky hybrid DNS question. I'll need to carefully read through the requirements and think through the different options.

Ah, the joys of hybrid networking. I'm just glad I don't have to explain this to the marketing team. They'd probably think we're just making up words like 'hosted zones' and 'zone transfers'.

Okay, this is a tricky one. Gotta use those inbound and outbound endpoints to bridge the gap between the cloud and on-prem. And don't forget the DHCP options - can't have those teams going rogue with their own DNS servers!

Hmm, looks like we need to use a combination of Route 53 Resolver, private hosted zones, and zone transfers to get this hybrid DNS setup working. No sweat, as long as we don't accidentally create a black hole in the process!
