SAFe® 5 DevOps Certification SAFe® 5 DevOps: Continuous Deployment 3

Question 1

Which SAFe® 5 concept emphasizes deploying to production continuously while decoupling when features are released to users?

Accepted Answer

Decouple Deployment from Release

Answer

Decoupling deployment from release, often implemented via feature toggles, allows teams to continuously deploy code to production while controlling precisely when features are made visible to users.

Question 2

What is a key characteristic of a 'rolling deployment' strategy in SAFe® 5 DevOps?

Accepted Answer

Instances are updated incrementally, with new and old versions running in parallel during the transition

Answer

Rolling deployments replace instances incrementally so that old and new versions coexist briefly, gradually shifting traffic to the new version without a full cutover.

Question 3

In SAFe® 5 DevOps, which deployment environment practice reduces the 'works on my machine' problem?

Accepted Answer

Using containers and Infrastructure as Code to create consistent, reproducible environments

Answer

Containers and Infrastructure as Code ensure every environment is created from the same definition, eliminating configuration drift that causes environment-specific failures.

Question 4

What is the relationship between automated testing and Continuous Deployment in SAFe® 5 DevOps?

Accepted Answer

Automated testing is a prerequisite for Continuous Deployment because it provides the confidence needed to deploy frequently

Answer

Automated testing across unit, integration, and acceptance levels provides the safety net required to confidently deploy frequently and quickly catch regressions before they reach production.

Question 5

In SAFe® 5 DevOps, what does 'Mean Time to Restore' (MTTR) measure?

Accepted Answer

The average time required to recover service after a production incident or failed deployment

Answer

MTTR measures how quickly a team can restore service after a failure, reflecting the effectiveness of deployment rollback strategies, incident response, and observability practices.
