1Z0-1072-25 Question 36
Single answerYou have just created an Oracle Linux 8 instance in a private subnet and want to schedule automated patch updates using Oracle Cloud Infrastructure (OCI) OS Management. After logging into the OS Management console, you notice that the instance is not listed. Which prerequisite must be met for the instance to be properly enrolled in the OS Management service?
- A
Enable the OS Management plugin through the Oracle Cloud Agent and apply the necessary IAM policies for OS Management.
- B
Assign a public IP address and open port 22 on the instance� VCN security list for OS Management access.
- C
Use an OCI custom image based on Oracle Linux 9 or higher to be recognized by OS Management.
- D
Create a separate block volume and mount it to your instance for storing patch repositories locally.
Show answer and explanation
Correct answer: A
Explanation
To configure OS Management for an OCI instance, you must enable the OS Management plugin through the Oracle Cloud Agent and grant IAM permissions allowing OS Management to manage the instance. Instances do not need a public IP if a proper network path (e.g., via Service Gateway or NAT Gateway) is established. Refer to the official Oracle Cloud Infrastructure OS Management documentation for more information on enabling the plugin and creating the necessary IAM policies.
- A. Correct.
Correct. The OS Management plugin must be enabled on the Oracle Cloud Agent running on your instance. You also need an IAM policy allowing OS Management to manage the instance. Without these prerequisites, OS Management cannot detect or manage the instance, even in a private subnet.
- B. Incorrect.
Incorrect. Having a public IP is not strictly required. You can configure OS Management with instances in private subnets using a Service Gateway or NAT Gateway. Port 22 is typically used for SSH, not for OS Management traffic.
- C. Incorrect.
Incorrect. OS Management supports Oracle Linux 7, 8, and 9 (among others) as long as the OS Management plugin is correctly enabled. You do not need a custom image based on Oracle Linux 9 specifically.
- D. Incorrect.
Incorrect. Creating a separate block volume for patch repositories is not a prerequisite. OS Management can pull patches from Oracle� repositories or custom repositories without requiring a dedicated block volume.
