Which solution will meet these requirements?
Configure the Lambda function to run in the VPC with the appropriate security group.
Set up a VPN connection from AWS to the data center. Route the traffic from the Lambda function through the VPN.
Update the route tables in the VPC to allow the Lambda function to access the on-premises data center through Direct Connect.
Create an Elastic IP address. Configure the Lambda function to send traffic through the Elastic IP address without an elastic network interface.
Explanations:
Configuring the Lambda function to run in the VPC with the appropriate security group allows it to communicate with resources in the private subnet, including the database in the on-premises data center via Direct Connect.
Setting up a VPN connection is unnecessary since Direct Connect is already in place for routing traffic. This option would introduce unnecessary complexity and latency.
While updating the route tables is part of the solution, simply modifying the route tables alone does not enable the Lambda function to access the database; it must be configured to run within the VPC first.
Creating an Elastic IP does not apply to AWS Lambda since it does not support assigning Elastic IPs directly. Lambda functions require an elastic network interface to route traffic through the VPC.
If I’m correct, the answer is:
Configure the Lambda function to run in the VPC with the appropriate security group.
