Amazon ANS-C01 Exam - Topic 4 Question 26 Discussion

Actual exam question for Amazon's ANS-C01 exam

Question #: 26
Topic #: 4

AnyCompany has acquired Example Corp. AnyCompany's infrastructure is all on premises, and Example Corp's infrastructure is completely in the AWS Cloud. The

companies are using AWS Direct Connect with AWS Transit Gateway to establish connectivity between each other.

Example Corp has deployed a new application across two Availability Zones in a VPC with no internet gateway. The CIDR range for the VPC is 10.0.0.0/16. Example

Corp needs to access an application that is deployed on premises by AnyCompany. Because of compliance requirements, Example Corp must access the application

through a limited contiguous block of approved IP addresses (10.1.0.0/24).

A network engineer needs to implement a highly available solution to achieve this goal. The network engineer starts by updating the VPC to add a new CIDR range of

10.1.0.0/24.

What should the network engineer do next to meet the requirements?

AIn each Availability Zone in the VPC, create a subnet that uses part of the allowed IP address range. Create a public NAT Sateway in each of the new
subnets. Update the route tables that are associated with other subnets to route application traffic to the public NAT gateway in the corresponding Availability
Zone. Add a route to the route table that is associated with the subnets of the public NAT gateways to send traffic destined for the application to the transit
gateway.

BIn each Availability Zone in the VPC, create a subnet that uses part of the allowed IP address range. Create a private NAT gateway in each of the new
subnets. Update the route tables that are associated with other subnets to route application traffic to the private NAT gateway in the corresponding
Availability Zone. Add a route to the route table that is associated with the subnets of the private NAT gateways to send traffic destined for the application to
the transit gateway.

CIn the VPC, create a subnet that uses the allowed IP address range. Create a private NAT gateway in the new subnet. Update the route tables that are
associated with other subnets to route application traffic to the private NAT gateway. Add a route to the route table that is associated with the subnet of the
private NAT gateway to send traffic destined for the application to the transit gateway.

DIn the VPC, create a subnet that uses the allowed IP address range. Create a public NAT gateway in the new subnet. Update the route tables that are
associated with other subnets to route application traffic to the public NAT gateway. Add a route to the route table that is associated with the subnet of the
public NAT gateway to send traffic destined for the application to the transit gateway.

Agreed, private NAT is the way to go for compliance!

Wait, why would they use a public NAT? That seems risky.

I think creating subnets in each Availability Zone is crucial, but I can't recall if we should use public or private NAT gateways. I feel like option A might be overcomplicating things.

I’m a bit confused about whether we need public or private NAT gateways in this scenario. I thought public gateways were for internet access, but this is all internal, right?

This question feels similar to one we practiced about routing traffic between VPCs. I think option B might be the best choice since it mentions a private NAT gateway.

I remember we discussed the importance of using private NAT gateways for internal traffic, but I'm not entirely sure if that's the right approach here.

This seems straightforward enough. I'll just create a single subnet with the allowed IP range, put a public NAT gateway in there, and route the traffic through that. Simple and effective.

I'm a bit confused on the difference between public and private NAT gateways here. I'll need to review the pros and cons of each option to determine the best approach.

Okay, I think I've got a plan. I'll create subnets in each AZ using the allowed IP range, and then route the traffic through private NAT gateways in those subnets to the transit gateway. That should give me the high availability they're looking for.

Hmm, the requirement to use a limited IP address range is an interesting constraint. I'll need to consider how to best route the traffic through the NAT gateway while still meeting that criteria.

I think the key here is to consider which financial statements provide the most comprehensive view of the company's overall financial situation. The balance sheet, income statement, and cash flow statement each provide important information, but I believe the combination of the cash flow statement along with the balance sheet and income statement would give the most complete picture.

Hmm, this looks like a tricky one. I'll need to think carefully about the requirements - a single dashboard with both threat/security and device health info. I'm guessing Appliance Status and Intrusion Events are the two widgets I need to configure.

This reminds me of that scene in The Matrix where Neo has to choose between the red and blue pill. Except in this case, it's like choosing between a public or private NAT gateway. *shrugs* Guess I'll just go with my gut and hope for the best!

Hmm, I think I've got it! Option B seems like the most logical choice, with the private NAT gateway in the subnet with the approved IP range. I bet the exam writer is trying to trick us with those public NAT gateway options. Nice try, but not this time!
