[All C9510-401 Questions]

A system administrator needs to set a new Liberty profile environment to support an application.

What should the administrator do to enable this environment for high availability and scalability of the application?

ADefine multiple server members in one collective controller.

BDefine multiple servers in a cluster in one collective controller.

CDefine multiple collective controllers within a Liberty collective.

DDefine multiple server members in multiple collective controllers.

Show Suggested Answer

Suggested Answer: B

Remember that coordinator election occurs whenever the view changes. Electing a new coordinator uses a lot of resources because this process causes increased network traffic and CPU consumption. Specifying a preferred coordinator server, whenever practical, helps eliminate the need to make frequent coordinator changes.

Ha! I bet the admins wish they could just define a single collective controller and call it a day. But in the real world, high availability means getting your hands dirty with multiple servers and controllers.

Hmm, I'm not sure. I was leaning towards C, but now I'm second-guessing myself. Multiple collective controllers? That sounds complicated.

I think the answer is B. Defining multiple servers in a cluster under one collective controller seems like the best way to achieve high availability and scalability.
