Oracle Database Administration 2019 Certified Professional — Question 33

Zero Downtime Patching uses Fleet Patching and Provisioning to patch Oracle Grid Infrastructure without bringing down Oracle RAC database instances.
Which three statements are true about Zero-Downtime Oracle Grid Infrastructure Patching? (Choose three.)

Answer options

• A. Zero Downtime Patching requires out-of-place patching of Oracle Grid Infrastructure 19c with Oracle RAC or Oracle RAC One Node databases of 19c or later releases and only the binaries in the Oracle Grid Infrastructure user space are patched.
• B. When using Zero Downtime Patching, the root.sh script must be executed manually with -nodriverupdate option.
• C. When using Zero Downtime Patching, Oracle Grid Infrastructure OS system software, kernel modules and system commands including ACFS, AFD, OLFS, and OKA are not updated.
• D. Zero Downtime Patching requires in-place patching of Oracle Grid Infrastructure 19c with Oracle RAC or Oracle RAC One Node databases of 19c or later releases and only the binaries in the Oracle Grid Infrastructure user space are patched.
• E. Zero Downtime Patching can be fully automated by selecting the option to automatically run the root.sh script.

Correct answer: A, B, C

Explanation

The correct answer includes A, B, and C, which accurately describe the requirements and limitations of Zero Downtime Patching. Option D is incorrect because it states in-place patching is required, which contradicts the zero downtime approach. Option E is also incorrect as it suggests complete automation, which is not the case for the manual execution of the root.sh script.
