Architecting on AWS Certification Non-Destructive Testing Methods 5

Question 1

A team wants to verify that CloudWatch alarms correctly trigger before deploying new auto-scaling policies to production. Which approach achieves this non-destructively?

Accepted Answer

Use the CloudWatch set-alarm-state API to force alarm states and verify downstream actions

Answer

set-alarm-state forces an alarm into OK, ALARM, or INSUFFICIENT_DATA state so you can verify that connected actions (SNS, Auto Scaling) fire correctly without real metric conditions.

Question 2

Which AWS X-Ray feature helps teams understand the impact of code changes on latency without introducing load into production?

Accepted Answer

X-Ray groups and filter expressions applied to existing trace data from a staging environment

Answer

Analyzing X-Ray traces from a staging environment with filter expressions gives accurate latency profiling without any production risk.

Question 3

A DevOps team needs to validate that a new CodePipeline configuration correctly deploys to dev before it can be promoted. Which CodePipeline feature enforces this gate non-destructively?

Accepted Answer

Manual approval action between the dev deploy stage and the production deploy stage

Answer

A manual approval action pauses the pipeline after dev deployment, allowing the team to validate the environment before the pipeline proceeds to production.

Question 4

An architect must confirm that Route 53 health checks correctly mark an endpoint unhealthy before switching DNS. What is the safest test method?

Accepted Answer

Configure a health check against a test endpoint that returns a non-200 status and verify the health check transitions to unhealthy

Answer

Testing health check logic against a dedicated test endpoint that deliberately returns an unhealthy response validates the behavior without touching live DNS records.

Question 5

Which AWS Config feature allows teams to evaluate whether resources comply with rules before those resources are provisioned, acting as a pre-deployment gate?

Accepted Answer

AWS Config proactive evaluation mode (proactive rules)

Answer

Proactive evaluation mode lets you run Config rules against a CloudFormation template before deployment so non-compliant resources are caught before they are created.
