You must propose an Oracle Data Guard configuration for a database supporting an OLTP workload that meets these permanent requirements: 1. Data loss is not permitted. 2. Read-only applications should not connect to the primary database instance. Additionally, there are these requirements, only one of which is ever done at any one time: 3. It should be possible to apply and test designated patches with a minimum amount of downtime. 4. Upgrading to a new database release should be performed with the least possible amount of downtime. 5. New application software releases should be tested against an exact up-to-date replica of the production database. You propose a primary database with one physical standby database configured in Maximum Protection mode. Which requirements do you meet? 

Answer options:

A. 2, 3, 4, and 5
B. 1, 2, 3, 4, and 5
C. 1 and 2
D. only requirement 5
E. only requirement 1

C

Maximum Protection mode ensures that zero data loss occurs if a primary database fails. Because this data protection mode prioritizes data protection over primary database availability, Oracle recommends that a minimum of two standby databases be used to protect a primary database that runs in maximum protection mode to prevent a single standby database failure from causing the primary database to shut down. Incorrect Answers: A, D: Maximum Protection mode ensures that zero data loss occurs if a primary database fails. References: https://docs.oracle.com/cd/B28359_01/server.111/b28294/protection.htm
