Amazon ANS-C01 Exam - Topic 6 Question 41 Discussion

A company ran out of IP address space in one of the Availability Zones in an AWS Region that the company uses. The Availability Zone that is out of space is assigned the10.10.1.0/24 CIDR block. The company manages its networking configurations in an AWS CloudFormation stack. The company's VPC is assigned the 10.10.0.0/16 CIDRblock and has available capacity in the 10.10.1.0/22 CIDR block.How should a network specialist add more IP address space in the existing VPC with the LEAST operational overhead?
D) Create a new AWS :: EC2 :: Subnet resource for the Availability Zone in the CloudFormation stack. Set the CidrBlock property to 10.10.2.0/24.
A) Update the AWS :: EC2 :: Subnet resource for the Availability Zone in the CloudFormation stack. Change the CidrBlock property to 10.10.1.0/22.
B) Update the AWS :: EC2 :: VPC resource in the CloudFormation stack. Change the CidrBlock property to 10.10.1.0/22.
C) Copy the CloudFormation stack. Set the AWS :: EC2 :: VPC resource CidrBlock property to 10.10.0.0/16. Set the AWS :: EC2 :: Subnet resource CidrBlock property to 10.10.1.0/22 for the Availability Zone.

A company ran out of IP address space in one of the Availability Zones in an AWS Region that the company uses. The Availability Zone that is out of space is assigned the

10.10.1.0/24 CIDR block. The company manages its networking configurations in an AWS CloudFormation stack. The company's VPC is assigned the 10.10.0.0/16 CIDR

block and has available capacity in the 10.10.1.0/22 CIDR block.

How should a network specialist add more IP address space in the existing VPC with the LEAST operational overhead?

Wait, can you really just change the CIDR block like that? Seems risky!

I’m leaning towards option C, but copying the stack seems like it could add unnecessary complexity. I need to double-check if that’s really the least overhead.

I feel like option A makes the most sense since we’re just expanding the existing subnet, but I’m a bit confused about the implications of changing the CidrBlock.

I remember a practice question where we had to modify the VPC settings, but this one feels different since we’re dealing with a specific subnet.

I think we need to update the subnet resource, but I'm not sure if changing the CidrBlock to /22 is the right move.

I'm a little confused by this question. The wording is a bit tricky, and I'm not sure I fully understand the implications of each option. I think I'll need to review the CloudFormation documentation again before deciding. Maybe I'll go with C just to be safe.

Okay, let's see here. The key is to add more IP address space with the least operational overhead. I'm leaning towards option B - updating the VPC CIDR block. That way we don't have to mess with the individual subnets. Seems like the cleanest solution.

Hmm, I'm a bit unsure about this one. I'm trying to decide between A and C. Updating the existing subnet seems simpler, but creating a new subnet might give us more flexibility down the line. I'll have to think it through carefully.

This seems like a straightforward networking question. I think I'll go with option A - updating the existing subnet in the CloudFormation stack. That should be the least disruptive approach.
