Final answer:
Yes, a single Lambda function can have access to multiple VPCs by configuring its VPC configuration settings.
Step-by-step explanation:
Yes, a single Lambda function can have access to multiple VPCs. Lambda functions are executed in an environment called the Lambda execution context, and they can be configured to access resources within the VPC using VPC configuration settings.
When creating a Lambda function, you can choose to either run it inside a VPC or outside a VPC. If you choose to run it inside a VPC, you can specify one or more VPCs that the function should be able to access.
For example, if you have two VPCs, VPC A and VPC B, and you want a Lambda function to access resources in both VPCs, you can configure the function with both VPCs specified in its VPC configuration settings.
