A system administrator has deployed an application. The development team has updated a new version of this application. The administrator needs to immediately deploy this updated application and guarantee that only this new edition is used by clients and that any service requests for the application are queued during the deployment of the new application.
How can the administrator achieve this task without any downtime to the application?
A. Perform a soft rollout.
B. Perform a hard rollout.
C. Perform an atomic rollout.
D. Perform a concurrent activation rollout.
Correct Answer: C
Explanation/Reference:
Explanation:
Performing an atomic rollout activates the new edition on half of the cluster first, and then activates the edition on the remaining half of the cluster. While the first half of the cluster is taken offline and updated, application requests are routed to the second half of the cluster. Verify that half the cluster can handle the entire load during the rollout period.
