IBM Exam C9510-401 Topic 1 Question 111 Discussion

Actual exam question for IBM's C9510-401 exam
Question #: 111
Topic #: 1
[All C9510-401 Questions]

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?

Show Suggested Answer Hide Answer
Suggested Answer: C

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.

Concurrent activation, huh? That's one way to keep the clients on their toes. But I prefer the hard rollout approach - rip the bandaid off and get it done.

I agree with Sharan, a concurrent activation rollout would be the most efficient way to deploy the updated application.

Soft rollout? That sounds like a gentle software update, not a hardcore system admin move. I'd go with the atomic rollout - quick, decisive, and no room for errors.

I think a concurrent activation rollout would be the best option to ensure no downtime.

I disagree, I believe a hard rollout would be more effective in this situation.
