RecognitionElastic IP addresses
VPC addressing/cost context; no standalone skill depth.
Key points
- Elastic IP addresses belong in public IPv4 attachment, routing, and cost investigations rather than standalone design depth.
Best-known use cases
- D2.1, D2.2, and D5.1: inspect the named public IPv4 association when it affects reachability or ongoing cost.
What candidates often confuse it with
- An Elastic IP supplies a public IPv4 address; an internet gateway and route provide the VPC internet path.
Key takeaway
Do not mistake address allocation for a complete route, filter, or high-availability configuration.
