Question

You are a software developer and working on a Node.js web application.

The app is ready to be deployed for further testing.

You want to deploy it with AWS Elastic Beanstalk, and the application should be put in a custom VPC.

You plan to specify the VPC settings in a .ebextensions configuration file.

Which description is correct?

A. B. C. D.

Correct Answer - B.

Option A is incorrect: Because the VPC settings should be put in the option_settings section instead of the Resources section.

Option B is CORRECT: Because the aws:ec2:vpc namespace is the correct place to customize the VPC settings such as VPCId and subnets.

Option C is incorrect: Because the question requires that the configurations should be put in the .ebextensions files.

Option D is incorrect: Because for VPC settings, the namespace should be aws:ec2:vpc.

Sure, I'd be happy to provide a detailed explanation!

The correct answer for this question is option B: Define the VPC configurations in the aws:ec2:vpc namespace.

Here's why:

When you deploy a Node.js web application using AWS Elastic Beanstalk, you can use a .ebextensions configuration file to specify various settings and configurations for your application. One of the settings you can specify is the VPC (Virtual Private Cloud) where your application should run.

To specify VPC settings in your .ebextensions configuration file, you need to use the aws:ec2:vpc namespace. This namespace allows you to specify settings related to the VPC, such as the VPC ID, the security group ID, and the subnet ID.

Here's an example of how to specify the VPC ID in the aws:ec2:vpc namespace:

yaml
option_settings: aws:ec2:vpc: VPCId: vpc-1234567890

In this example, vpc-1234567890 is the ID of the VPC where you want to run your application.

Option A, defining the VPC settings in the Resources section of the .ebextensions configuration file, is incorrect. The Resources section is used to create AWS resources, such as an EC2 instance or an S3 bucket. It is not used to specify VPC settings.

Option C, creating a saved configuration that contains the VPC settings and applying it using EB CLI, is also incorrect. While you can create a saved configuration with VPC settings, it's not necessary to do so in this case. You can specify the VPC settings directly in the .ebextensions configuration file.

Option D, configuring the VPC in the option_settings namespace, is also incorrect. While you do need to use the option_settings namespace to specify VPC settings, you need to use the aws:ec2:vpc namespace specifically, not the generic option_settings namespace.
