Amazon ANS-C01 Exam - Topic 2 Question 15 Discussion

A company has a hybrid cloud environment. The company's data center is connected to the AWS Cloud by an AWS Direct Connect connection. The AWS environment includes VPCs that are connected together in a hub-and-spoke model by a transit gateway. The AWS environment has a transit VIF with a Direct Connect gateway for on-premises connectivity.The company has a hybrid DNS model. The company has configured Amazon Route 53 Resolver endpoints in the hub VPC to allow bidirectional DNS traffic flow. The company is running a backend application in one of the VPCs.The company uses a message-oriented architecture and employs Amazon Simple Queue Service (Amazon SQS) to receive messages from other applications over a private network. A network engineer wants to use an interface VPC endpoint for Amazon SQS for this architecture. Client services must be able to access the endpoint service from on premises and from multiple VPCs within the company's AWS infrastructure.Which combination of steps should the network engineer take to ensure that the client applications can resolve DNS for the interface endpoint? (Choose three.)
A) Create the interface endpoint for Amazon SQS with the option for private DNS names turned on. and D) Use the automatically created private hosted zone for sqs.us-east-1.amazonaws.com with previously created necessary records that point to the interface endpoint. Associate the private hosted zones with other VPCs. and F) Access the SQS endpoint by using the private DNS name of the interface endpoint .sqs.us-east-1.vpce.amazonaws.com in VPCs and on premises.
B) Create the interface endpoint for Amazon SQS with the option for private DNS names turned off.
C) Manually create a private hosted zone for sqs.us-east-1.amazonaws.com. Add necessary records that point to the interface endpoint. Associate the private hosted zones with other VPCs.
E) Access the SQS endpoint by using the public DNS name sqs.us-east-1 amazonaws.com in VPCs and on premises.

F is the best option for accessing the endpoint securely.

Wait, can you really use public DNS for SQS? That seems risky!

I’m a bit confused about the public DNS access. I thought we should avoid using public DNS for internal communication, so option E seems wrong to me.

I feel like we practiced a question similar to this where using the automatically created private hosted zone was the right choice. So, option D might be the way to go here.

I'm not entirely sure about the private hosted zone part. I think we might need to manually create one if we want to control the records, which makes option C seem plausible.

I remember we discussed the importance of enabling private DNS names for interface endpoints, so I think option A is definitely a step we should take.

The question is really testing our understanding of hybrid cloud networking and DNS resolution. I'll need to carefully read through all the details and make sure I understand the full architecture before deciding on the right steps.

Hmm, I'm not sure about turning off the private DNS names for the interface endpoint. That seems like it would prevent the clients from being able to resolve the endpoint properly. I think the right approach is to enable private DNS and manage the hosted zones.

I feel pretty confident about this one. The key is to set up the interface endpoint with private DNS names enabled, and then create/associate the necessary private hosted zones across the VPCs. That should allow the client apps to resolve the DNS properly.

Hmm, I'm a bit unsure about this one. Removing all public IP addresses could be tricky, and I'll need to make sure the SREs can still access the bastion host remotely. I'll need to think through the pros and cons of each option.

Good point. I think the main difference is that with option D, you don't have to manually create the private hosted zone, which could be more convenient. But with option C, you have more control over the DNS setup.

Hmm, I'm a bit confused about the difference between options C and D. They both mention creating a private hosted zone, but C says to do it manually while D says to use the automatically created one. I wonder what the implications of each approach are.

I agree. The options mention using private DNS names and creating a private hosted zone, so I believe we need to do that to ensure the DNS resolution works.

This question seems to be testing our understanding of how to configure DNS for an interface VPC endpoint. I think the key is to ensure that the client applications can resolve the DNS for the SQS endpoint, both from on-premises and from the multiple VPCs.
