Which two manifest attributes must be specified at a minimum with corresponding values in the deployment descriptor of the application that requires

You deployed a Java EE Shared Library and want to use it from an application that is also
deployed on the same cluster.
Which two manifest attributes must be specified at a minimum with corresponding values in the
deployment descriptor of the application that requires

A.
Implementation-Version

B.
Specification-Version

C.
Extension-Name

D.
Specification-Vendor

E.
Implementation-Vendor

Explanation:
When an application that references a shared library or package is deployed,
WebLogic Server checks the names and version string requirements against the libraries
registered with the server. If an exact match for a library or package name is not found, or if the
version requirements are not met, the application deployment fails.
If WebLogic Server finds a name and version string match for all of the libraries referenced in the
application, the server adds the libraries’ classes to the classpath of the referencing application
and merges deployment descriptors from both the application and libraries in memory. The
resulting deployed application appears as if the referenced libraries were bundled with the
application itself.
Note:
As a best practice, your development team should always include version string information for a
library or optional package in the manifest file for the deployment. See Editing Manifest Entries for
Shared Libraries in Developing Applications for Oracle WebLogic Server for more information.
If you are deploying a library or package that does not include version string information, you can
specify it at the command line using one or both of the following options:
libspecver—Defines a specification version for the library or package.

libimplver—Specifies an implementation version for the library or package.
