Decision Framework and PoC Design Quiz
This quiz tests your understanding of Decision Framework and PoC Design.
- What does this document identify as "the biggest gap" among decision factors?
- A) Tag naming conventions
- B) CUJ-level RTO/RPO targets
- C) The EKS version number
- D) VPC CIDR size
Show Answer
Answer: B) CUJ-level RTO/RPO targets
Explanation: Without RTO/RPO targets defined per CUJ, you can't judge whether an A/B EKS Runtime failover is fast enough, which data ownership model is actually recoverable, or whether AZ configuration differences matter. This target should be defined before anything else.
- How do ALB weighted forwarding and fail-open relate?
- A) An unhealthy group always fails over to another
- B) Automatic inter-group failover and unhealthy routing inside a group are distinct
- C) Weights guarantee RTO
- D) Targets replicate across Regions
Show Answer
Answer: B) Automatic inter-group failover and unhealthy routing inside a group are distinct
Explanation: Weighted forwarding does not automatically transfer an empty/unhealthy group’s weight to another group. Evaluate the selected group’s DNS/routing health thresholds separately.
- Why is "decision matrix dry-run" run as PoC-0, before all other PoCs?
- A) Because it's the cheapest option
- B) Because every other option — independent boundary judgment, Hybrid configurations, etc. — sets "reproducible via a decision matrix" as its condition for validity, so no PoC result converts into a standard without one
- C) Because it requires AWS SA approval
- D) Because it's unrelated to the other PoCs
Show Answer
Answer: B) Because every other option — independent boundary judgment, Hybrid configurations, etc. — sets "reproducible via a decision matrix" as its condition for validity, so no PoC result converts into a standard without one
Explanation: The decision matrix dry-run has two people independently apply the matrix to 10–15 representative workloads, using local example targets of disagreement under 20% and exceptions under 15%. The resulting estimated Account/VPC/cluster counts determine the measurement targets for the remaining PoCs.
- Which statement correctly describes unused-Region controls?
- A) Every default Region can be disabled
- B) Combine SCPs, detection, supported opt-in disabling, and existing-resource cost checks
- C) GuardDuty alone blocks APIs
- D) Disabling a Region deletes all resources
Show Answer
Answer: B) Combine SCPs, detection, supported opt-in disabling, and existing-resource cost checks
Explanation: Regions enabled by default cannot be disabled. Opt-in disabling does not delete existing resources or ensure charges stop, so plan cleanup and access controls together.
