Question 50
A professional architect is reviewing two independent workstreams. Requirement A: Capacity planners need a monthly cost forecast that reflects a new Region and expected usage growth before deployment. Requirement B: Two regional Transit Gateways must exchange approved network prefixes without provisioning a separate VPC-to-VPC peering mesh. Choose TWO remedies that meet A and B respectively.
Explanation
Correct Answers
This action meets the independently stated requirement B: Two regional Transit Gateways must exchange approved network prefixes without provisioning a separate VPC-to-VPC peering mesh. Transit Gateway peering requires explicit routing between the regional gateways. A direct acceptance check is: Traffic crosses the regional peering attachment only for specifically installed and approved prefixes.
This action meets the independently stated requirement A: Capacity planners need a monthly cost forecast that reflects a new Region and expected usage growth before deployment. Architecture forecasts require explicit usage assumptions rather than extrapolation without design changes. A direct acceptance check is: Proposed architecture cost estimates can be traced to entered quantities and forecast assumptions.
Incorrect Answers
This action targets a different technical need: An organization needs central inspection of east-west traffic from multiple spoke VPCs without asymmetric return flows. It does not replace either required solution in A or B. Stateful network inspection requires symmetric paths through the selected inspection appliance; verify the two stated requirements independently rather than accepting an unrelated change.
This action targets a different technical need: A central networking account must share an existing Transit Gateway with application accounts without duplicating it. It does not replace either required solution in A or B. AWS RAM can share supported resources while ownership remains in a central account; verify the two stated requirements independently rather than accepting an unrelated change.
This action targets a different technical need: Dozens of overprovisioned EC2 instances need evidence-based CPU and memory sizing recommendations before changing families. It does not replace either required solution in A or B. Compute Optimizer uses resource metrics and recommendations but must be checked against workload SLOs; verify the two stated requirements independently rather than accepting an unrelated change.
