The Center of Excellence (COE) team is performing a design review of multiple applications. The team identifies that some applications are not in line with the Center-out™ business architecture.

Which two of the following design statements are uncharacterisitc of the Center-out approach? (Choose Two)
A . The organization currently operates in one region only, so the design has one enterprise layer and one production application layer. Separate the organization-wide assets from the assets that are specific to the production application.
B . All the channels in an organization have their own back-end-specific business logic to retrieve and display the required data.
C . The organization uses two different legacy database systems: define data access, and persistence with the data virtualization layer.
D . The organization uses two different legacy database systems, so define data access and data presentation rules that are very specific to the existing database vendors. The execution of database queries is faster, and output can be displayed very quickly with this design approach.
