Multiple Choice

A business critical enterprise resource planning (ERP) system uses a central database at a company's primary data center.

Which architectural approach to implement service continuity for the ERP database will meet the RTO and RPO targets?

• B) Implement asynchronous replication of the ERP database, application, and middle tiers to ensure the ERP system is back online with less than eight hours of data loss within 30 minutes of an event.
• C) Perform daily full database backups to tape and overnight ship the backup tape media from one data center to the other to ensure the ERP system is back online with less than eight hours of data loss within 30 minutes of an event.
• D) Implement synchronous database replication and configure application logic to ensure transactions are identical in both data centers as the recovery objectives do not allow for any inflight data loss.
