The 1z0-998-21 exam contains 72-76 questions with 120 minutes minutes on the clock. That combination rewards candidates who have rehearsed under realistic conditions — which is exactly what the software simulation version of the Prep4away materials is for.
The official outline divides the 1z0-998-21 exam into weighted domains, including:
- DB System Deployment & Management (25%)
- Patching, Backup & Recovery (20%)
