Rollback Strategies for Failed Deployments

Submit

2. How do container orchestration platforms like Kubernetes support rollback strategies?

They eliminate the need for version control

They provide declarative state management and automatic version tracking

They increase deployment time significantly

They remove the need for monitoring

3. What is the purpose of a 'smoke test' in rollback planning?

To verify basic system functionality after deployment or rollback

To eliminate all bugs in production

To measure code quality metrics

To train developers on deployment procedures

Submit

5. In continuous delivery, what is the relationship between deployment frequency and rollback risk?

Higher frequency increases risk, so rollbacks are unnecessary

Lower frequency reduces the need for rollback strategies

Frequent small changes reduce blast radius, making rollbacks simpler

Deployment frequency has no effect on rollback complexity

6. What is the main benefit of infrastructure-as-code (IaC) for rollback procedures?

It makes code more readable

It enables reproducible infrastructure states for fast rollbacks

It eliminates the need for testing

It increases deployment costs

7. Which strategy involves running two versions simultaneously to compare behavior?

Rolling deployment

Shadow deployment

Instant rollback

Sequential deployment

Submit

9. What is a 'circuit breaker' pattern used for in deployment strategies?

To physically disconnect servers

To stop cascading failures by failing fast and rolling back

To increase network bandwidth

To replace load balancers

10. Which tool or technique allows you to automatically detect anomalies that trigger rollbacks?

Manual code review

Observability and monitoring systems

Database backups

Team communication channels

11. What is the primary goal of a rollback strategy in continuous deployment?

Restore the system to a known stable state after a failed deployment

Increase the speed of development cycles

Reduce the number of developers on a team

Eliminate the need for testing

12. In a canary deployment, what percentage of traffic typically goes to the new version initially?

50%

5-10%

100%

0%

13. How do feature flags relate to rollback strategies in AutoOps?

They provide a way to disable problematic features without full rollback

They replace the need for version control

They eliminate the need for testing

They increase deployment time

14. What is the primary risk of a full immediate rollback strategy?

It takes too long to execute

Loss of recent user data if database migrations occurred

It requires manual approval from all stakeholders

It increases deployment frequency

15. In continuous delivery, what does 'immutable infrastructure' enable regarding rollbacks?

Faster rollbacks by switching to a previous known-good image

Elimination of all bugs in production

Removal of deployment pipelines

Automatic bug fixes without developer involvement

16. Which metric is most important for determining if a rollback should be triggered?

Number of code commits per day

Error rate and system health indicators

Team size

Database size

17. What is a critical advantage of automated rollback in continuous delivery?

It eliminates the need for monitoring

It reduces manual intervention and speeds recovery time

It prevents all deployment failures

It removes the need for version control

18. Which rollback approach allows you to gradually shift traffic to detect issues before full deployment?

Blue-green deployment

Canary release

Full rollback

Shadow deployment

19. In a blue-green deployment model, what does the 'green' environment represent?

The production environment currently serving users

The new version ready to be promoted to production

The development environment for testing

The backup database for disaster recovery
