Oracle Database Administration II — Question 50

Which three are true about upgrading Oracle Grid Infrastructure? (Choose three.)

Answer options

• A. A direct upgrade can be performed only from the immediately preceding Oracle Grid Infrastructure version.
• B. The newer version is installed in a separate Oracle Grid Infrastructure home on the same server as the existing version.
• C. An existing Oracle base can be used.
• D. The upgrade process will automatically install all mandatory patches for the current version of Oracle Grid Infrastructure.
• E. Existing Oracle Database instances must be shut down before starting the upgrade.
• F. Only the grid user can perform the upgrade.

Correct answer: B, C, E

Explanation

Option B is correct because during an upgrade, a new Oracle Grid Infrastructure home is created alongside the existing one. Option C is valid as you can utilize an existing Oracle base during the upgrade. Option E is necessary since existing Oracle Database instances need to be shut down to prevent data inconsistencies during the upgrade process. Options A, D, and F are incorrect for various reasons; for instance, upgrades can be performed from versions further back than just the immediately preceding one, and not all mandatory patches are installed automatically.
