What task(s) does an administrator need to perform in order to create a new WebSphere cell and implement a horizontal scaling topology?
A. Federate nodes and create multiple clusters B. Load balance multiple HTTP servers using EDGE Components C. Deploy multiple database servers using a high availability software product D. Federate nodes and create cluster members across multiple machines.
Creating WebSphere cells and implementing horizontal scaling topology would require the use of federated nodes and creating cluster members across multiple machines. This means that the answer to this question is D. If you would like to create a cell profile in WebSphere, you will need a profile management tool for that. A cell profile is a combination of two different profiles.
The first is an application server profile and the second one is a deployment manager profile. You would need to create this when you would like to test a new software. This is perfect for testing environments. Aside from the application server, you need to make sure that your IP address matches with your profile.
