Correct Answer: ADF
Explanation/Reference:
Explanation:
A: An Oracle home is the directory in which you install Oracle Database binaries, and from which Oracle Database runs. Use Oracle Appliance Manager (through oakcli commands) to create and manage multiple Oracle homes and databases on Oracle Database Appliance.
Oracle Database Appliance supports multiple Oracle Homes including different versions for Oracle Database 11g Release 2, 11gR2 and Oracle Database Release 12c Release 1.
D: You can use Cluster Verification Utility (CVU) to assist you with system checks in preparation for starting an upgrade.
F: The same user that owned the earlier release Oracle Grid Infrastructure software must perform the Oracle Grid Infrastructure 12c Release 1 (12.1) upgrade. Before Oracle Database 11g, either all Oracle software installations were owned by the Oracle user, typically oracle, or Oracle Database software was owned by oracle, and Oracle Clusterware software was owned by a separate user, typically crs.
