CoreAmazon VPC
Full configure, optimize, audit, and troubleshoot task surface.
Key points
- VPC operations combine addressing, subnets, routes, gateways, endpoints, filters, flow evidence, and cost paths.
Best-known use cases
- D2.1, D2.2, and D5.1: configure or troubleshoot the named VPC flow from source through its return path.
What candidates often confuse it with
- A VPC defines the network boundary; route tables choose paths, security controls filter them, and endpoints or gateways provide targets.
Key takeaway
Localize the address, route, attachment, filter, DNS, and return-path layer before making a VPC change.
