VPC

Also written as Virtual Private Cloud

An isolated, private section of a cloud provider's network where you control which resources can talk to each other and to the public internet.

Think of it like

Like a private, gated office park within a larger city — you control which gates are open to the public street and which buildings inside can reach each other.

Junior or senior?

Junior sounds like

Has only deployed into a VPC someone else built.

Senior sounds like

Has designed the subnet and routing rules themselves.

Ask them

“Have you designed a VPC's subnets and routing yourself, or only deployed into one that was already set up?”
