The 1Z1-160日本語 exam is Oracle's official test for the Oracle Database credential, a certification at the Professional level. Earning it tells employers your skills have been verified by the vendor itself, which carries real weight in hiring and promotion decisions. Within the same certification track, it sits alongside Oracle Database Cloud Administrator Certified Professional, so it can also serve as a stepping stone toward those credentials.

Oracle divides the Oracle Database Cloud Service (1Z1-160日本語版) exam into 6 domains. The largest ones are Database Cloud Service Architecture and Administration, Database Deployment Monitoring and Maintenance, Database Deployment Access and Security — together these account for the bulk of your score, so start there.
