How many subnets should I reference in severless.yaml for Lambda deploying

Hi, new here!

My lambda functions lives outside VPC, but now we have a requirements of accessing restricted services so now we need to add VPC configurations to serverless.yaml

when I do it with console, after selecting my VPC it show me 3 different VPC, my question is which one should I select and can I select all?

looking forward for response!
Thanks
Mohsin,

You get what you settle for

You’ll need to pick the VPC (and subnets) that contain the resources you need to access. We can’t tell you which ones without loads more details.
