• Question 41:

  When a new security patch is released for the Oracle Database software on a BaseDB VM system, what is the recommended approach for applying it in a production environment?

  B. Download the patch and apply it to a non-production environment that mirrors the production environment for testing before applying it to production.
  C. Wait for Oracle Cloud Infrastructure to automatically apply the security patch to all BaseDB VM systems.
  D. Apply the patch to a production standby database (if one exists) and then failover to the patched standby.
  B. Download the patch and apply it to a non-production environment that mirrors the production environment for testing before applying it to production.

• Question 42:

  When provisioning a Base Database Service (BaseDB) virtual machine (VM) instance in Oracle Cloud Infrastructure (OCI), which of the following actions MUST be performed before launching the DB system?

• Question 45:

  In the context of BaseDB Database Lifecycle Management, what is the primary purpose of a "pre-check" utility before applying a patch or upgrading the database?

  A. To automatically back up the database before the patch or upgrade.
  B. To determine if the patch or upgrade is compatible with the existing database environment and identify potential conflicts.
  C. To install the patch or upgrade in a test environment for validation.
  D. To optimize the database performance after the patch or upgrade.
  E. To migrate data to a different storage tier.
