Amazon Exam ANS-C01 Topic 6 Question 34 Discussion

Actual exam question for Amazon's ANS-C01 exam

Question #: 34
Topic #: 6

An AWS CloudFormation template is being used to create a VPC peering connection between two existing operational VPCs, each belonging to a different AWS account. All necessary components in the 'Remote' (receiving) account are already in place.

The template below creates the VPC peering connection in the Originating account. It contains these components:

AWSTemplateFormation Version: 2010-09-09

Parameters:

Originating VCId:

Type: String

RemoteVPCId:

Type: String

RemoteVPCAccountId:

Type: String

Resources:

newVPCPeeringConnection:

Type: 'AWS::EC2::VPCPeeringConnection'

Properties:

VpcdId: !Ref OriginatingVPCId

PeerVpcId: !Ref RemoteVPCId

PeerOwnerId: !Ref RemoteVPCAccountId

Which additional AWS CloudFormation components are necessary in the Originating account to create an operational cross-account VPC peering connection with AWS CloudFormation? (Select two.)

AResources:NewEC2SecurityGroup:Type: AWS::EC2::SecurityGroup

BResources:NetworkInterfaceToRemoteVPC:Type: ''AWS::EC2NetworkInterface''

CResources:newEC2Route:Type: AWS::EC2::Route

DResources:VPCGatewayToRemoteVPC:Type: ''AWS::EC2::VPCGatewayAttachment''

EResources:newVPCPeeringConnection:Type: 'AWS::EC2VPCPeeringConnection'PeerRoleArn: !Ref PeerRoleArn

I'm surprised option A isn't one of the correct answers. You'd think you'd need a security group to allow traffic between the VPCs, but I guess the peering connection takes care of that.

The AWS CloudFormation template already includes the necessary components for creating the cross-account VPC peering connection.

The VPC peering connection allows communication between the VPCs without the need for a separate security group.

Option A is not needed because the VPC peering connection handles the traffic between VPCs.

Haha, I can already see someone choosing option B and trying to create a 'NetworkInterfaceToRemoteVPC' - that's just not how it works!

That makes sense, we need to focus on creating a new route and attaching a VPC gateway for the peering connection.

I think the necessary components are actually option C and option D.

Yeah, creating a 'NetworkInterfaceToRemoteVPC' wouldn't help in setting up a VPC peering connection.

I agree, option B is definitely not the right choice here.

But option A is for creating a security group, not for VPC peering connection.

You're right, I misunderstood the question. Option E is definitely needed for the VPC peering connection.

I'm not sure why option E is there, it doesn't seem relevant to the question. But yeah, C and D are the right answers.

The correct answers are C) Resources:newEC2Route:Type: AWS::EC2::Route and D) Resources:VPCGatewayToRemoteVPC:Type: ''AWS::EC2::VPCGatewayAttachment''. These components are necessary to create routing between the two VPCs and establish the peering connection.

That makes sense, those components are essential for setting up the VPC peering connection between the two accounts.
