Amazon Exam ANS-C01 Topic 6 Question 41 Discussion

Actual exam question for Amazon's ANS-C01 exam

Question #: 41
Topic #: 6

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?

AUpdate the AWS :: EC2 :: Subnet resource for the Availability Zone in the CloudFormation stack. Change the CidrBlock property to 10.10.1.0/22.

BUpdate the AWS :: EC2 :: VPC resource in the CloudFormation stack. Change the CidrBlock property to 10.10.1.0/22.

CCopy 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.

DCreate a new AWS :: EC2 :: Subnet resource for the Availability Zone in the CloudFormation stack. Set the CidrBlock property to 10.10.2.0/24.

Wow, this is a real brain-teaser. I can see the merits of both A and C, but I think I'll go with A. Gotta love those CloudFormation shortcuts!

I disagree, I believe option D is better. Creating a new subnet with a different CIDR block would provide more flexibility in the long run.

I don't know, guys. All this networking stuff makes my head spin. I'm just going to go with whatever the answer key says is correct.

Option D is just weird. Why create a new subnet when we have available capacity in the existing one? Definitely not that one.

I'd have to go with C. Creating a new VPC with the larger CIDR block seems like the safest bet, even if it's a bit more work.

I see your point, but updating the existing subnet might be easier and quicker.

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.

That's a good point. It might be safer to create a new VPC with more IP address space.

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.
