You are responsible for installing and setting up WebLogic Server to support the development, testing, and production of an application. Each phase of the application's life cycle has different scalability, performance, and security requirements. How will you implement this?
To meet different scalability, performance, and security requirements across development, testing, and production phases, it is best to create three separate domains. Each domain can be tailored to the specific needs of each phase, allowing for individual configuration, tuning, and security settings appropriate to development, testing, and production environments.
I guess it is D. One domain in develoment mode, another for testing and finally the prod environment.
Ans can be C as well. Because for all dev, testing we usually have one domain created. Then we can scale , tune this particular domain accordingly by creating clusters, more managed servers etc.
Standalone Server Domain: For development or test environments, you may want to deploy a single application and server independently from servers in a production domain. In this case, you can deploy a simple domain consisting of a single server instance that acts as an Administration Server that, and also hosts the applications you are developing. The wl_server domain that you can install with WebLogic Server is an example of a standalone server domain.
So I think it is B
The domain's requirements are different, that are security and operation mode, therefor i believe that D is the correct answare
