What are two benefits of using Optim archiving for application decommissioning? (Choose two.)

A.
Reduced maintenance costs because application and database maintenance and license fees are no longer paid for the old application and its database, but data remains accessible to the user community.

B.
Decommissioned data is needed every day by end-users and Optim caches it in memory so access is faster then the production database.

C.
Reporting from the application against the archived data can be cheaper using tiered storage.

D.
Optim can store decommissioned data in a compressed format so it will take less storage then it did in production.

E.
Applications must continue to use data in a seamless manner.
