IBM Exam C9510-401 Topic 1 Question 84 Discussion

Actual exam question for IBM's C9510-401 exam

Question #: 84
Topic #: 1

A web application was deployed on a WebSphere Application Server cluster. While users are using the application, one of the cluster servers fails and the users lose their working data.

What can the system administrator configure to ensure users can continue to work if one of the cluster server fails?

AAn increased session timeout.

BA cluster of external HTTP servers.

CA load balancer to spread work between existing servers.

DA WebSphere eXtreme Scale HTTP session management.

Show Suggested Answer

Suggested Answer: D

WebSphere eXtreme Scale can dynamically process, partition, replicate, and manage application data and business logic across hundreds of servers. It provides transactional integrity and transparent fail-over to ensure high availability, high reliability, and consistent response times.

That's true, A longer session timeout might help, but I think a load balancer offers better availability and reliability.

But wouldn't increasing the session timeout also help in case of server failure? Option A could be a good choice too, right?

I agree with A load balancer sounds like the best solution to ensure continuity in case of server failure.

I think we should go with option C, a load balancer. It can help spread the workload and prevent data loss.

Hmm, I'm torn between options C and D. Both seem like viable solutions, but I think the WebSphere eXtreme Scale option might be the more robust and scalable choice in the long run.

A cluster of external HTTP servers (option B) sounds like it could work, but that seems like overkill for this scenario. Wouldn't a load balancer or the WebSphere session management be a more efficient solution?

I'm not convinced that an increased session timeout (option A) is the right answer here. That might just delay the inevitable, but it won't really solve the problem of losing user data when a server fails.

Ah, yes, I remember learning about this in my WebSphere training. I think option C, a load balancer, is the way to go. It's a simple and effective solution to distribute the load across the cluster.

I think option D, using WebSphere eXtreme Scale for session management, could also be a good choice.

Hmm, this is a tricky one. I'm leaning towards option D, WebSphere eXtreme Scale HTTP session management, as that seems like the most comprehensive solution to handle failover in a WebSphere cluster.

I'm not sure about this question. It seems to be testing our knowledge of WebSphere and session management, which isn't my strongest area. But I'll give it my best shot.
