Your team has set up a testing environment using VPC and EC2 Instances. An application is being hosted on these instances. Some housekeeping scripts are being developed using AWS Lambda that would need to delete files created by these EC2 Instances on their respective EFS. What is the initial configuration that needs to be put in place?

Answer options:

A.Ensure to use the --vpc-config when creating the AWS Lambda function.
B.Ensure to use the --vpc-config when creating the Ec2 instance.
C.Ensure the VPC has a route entry to the Lambda function.
D.Ensure an Internet gateway is attached to the VPC.

Answer – A
The AWS Documentation mentions the following.
AWS Lambda runs your function code securely within a VPC by default. However, to enable your Lambda function to access resources inside your private VPC, you must provide additional VPC-specific configuration information that includes VPC subnet IDs and security group IDs. AWS Lambda uses this information to set up elastic network interfaces (ENIs) that enable your function to connect securely to other resources within your private VPC.Options B and C are incorrect since these are not valid configurations.
Option D is invalid since you would ideally want to keep the VPC private.
