Amazon Exam ANS-C01 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.

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!

Wow, this is a tricky one! With all the VPC, subnet, and routing configurations, it's like navigating a maze blindfolded. I hope I can keep my sanity while solving this problem.

B) In 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.

I think the network engineer should choose option A.
