Show Suggested Answer

Suggested Answer: B

Backward Compatibility with the previous AEM Version is out of scope for the Pattern Detector tool, while doing an AEM upgrade. The Pattern Detector tool is a tool that scans an existing AEM code base and identifies patterns that are incompatible with AEM as a Cloud Service or newer versions of AEM on-premise. The tool does not check for backward compatibility with older versions of AEM, as this is not a requirement for upgrading.

I'm leaning towards Option D. The @Designate annotation seems to be the preferred way to bind multiple configurations to a service.

Option B looks like the way to go. Using the OSGi service component annotations is the recommended approach for multi-tenancy in AEM.

Hmm, that makes sense too. It's important to consider the specific requirements of the AEM application.

I disagree, I believe option A is the best choice as it uses @Component with factory=true for multi-tenancy setup.

I think option D is recommended because it uses @Designate for configuration binding.
