QUESTION: 16 Exam Topic: Mix Questions

You are currently defining a release strategy for an app, named APP-01.
The strategy should allow you to keep the time it takes to deploy new releases of the app to a minimum. The strategy should also allow you to roll back in the shortest time required.
Which of the following is the release strategy you should use?

Red/Black deployment
Rolling deployment
“Big Bang” deployment
Canary deployment

Answer(s): A

Explanation:

Canary deployment
With canary deployment, you deploy a new application code in a small part of the production infrastructure.
Once the application is signed off for release, only a few users are routed to it. This minimizes any impact. With no errors reported, the new version can gradually roll out to the rest of the infrastructure.

QUESTION: 17 Exam Topic: Mix Questions

Your company hosts a web application in Azure, and makes use of Azure Pipelines for managing the build and release of the application.
When stakeholders report that system performance has been adversely affected by the most recent releases, you configure alerts in Azure Monitor.
You are informed that new releases must satisfy specified performance baseline conditions in the staging environment before they can be deployed to production.
You need to make sure that releases not satisfying the performance baseline are prevented from being deployed.
Which of the following actions should you take?

You should make use of a branch control check.
You should make use of an alert trigger.
You should make use of a gate.
You should make use of an approval check.

Answer(s): C

Explanation:

Scenarios and use cases for gates include:
Quality validation. Query metrics from tests on the build artifacts such as pass rate or code coverage and deploy only if they are within required thresholds.
Use Quality Gates to integrate monitoring into your pre-deployment or post-deployment. This ensures that you are meeting the key health/performance metrics (KPIs) as your applications move from dev to production and any differences in the infrastructure environment or scale is not negatively impacting your KPIs.
Note: Gates allow automatic collection of health signals from external services, and then promote the release when all the signals are successful at the same time or stop the deployment on timeout. Typically, gates are used in connection with incident management, problem management, change management, monitoring, and external approval systems.
