Instance principals in OCI allow compute instances to directly make API calls against OCI services without requiring a user account. To set up instance principals, the following steps are necessary:

A. Deploy the application and SDK:The application running on the instances must use the OCI SDK or CLI to make API calls.

B. Create a dynamic group:Define a dynamic group with matching rules to identify which instances can use the API permissions.

C. Create a policy:Write an IAM policy that grants the dynamic group the necessary permissions to access services.

Option D is NOT necessarybecause instances in a dynamic group use instance principals to authenticate and do not require Auth Tokens, which are used for user authentication with APIs.

In Oracle Cloud Infrastructure (OCI), understanding how private IP addresses work is crucial for configuring network interfaces and managing instances within your Virtual Cloud Network (VCN).

Primary VNIC and Private IP Address:

When an instance is launched in OCI, it is attached to a Virtual Network Interface Card (VNIC). The primary VNIC, which is automatically created during the instance launch, is associated with a primary private IP address by default. This private IP address is essential for the instance to communicate within the VCN. The primary private IP address is automatically assigned and cannot be removed from the primary VNIC while the instance is running.This supports the statementC.

Additional Private IPs:

Contrary to statement B, each VNIC can indeed have multiple private IP addresses, but by default, the primary VNIC comes with only one primary private IP. You can manually add secondary private IPs if needed. However, the additional IPs are not assigned by default; hence,Ais incorrect.

Public IP Association:

For instances requiring internet access, a public IP address can be optionally assigned to the private IP address if the instance is in a public subnet. This is critical for scenarios where an instance needs to communicate with the internet or external networks.This aligns with statementD.

In Oracle Cloud Infrastructure (OCI), Identity and Access Management (IAM) policies are used to control access to resources. The policy in optionCis invalid because"any-user"is not a valid principal in OCI IAM policies. OCI policies can only grant permissions togroupsordynamic groups, but not to arbitrary users.

Here’s an explanation for each option:

A. Allow dynamic-group 'Default'/'FrontEnd' to manage instance-family in compartment Project-A: This is valid. It grants the dynamic group 'FrontEnd' the ability to manage instances within the Project-A compartment.

B. Allow group 'Default'/'A-Admins' to manage all-resources in compartment Project-A: This is valid. It provides full administrative access to all resources in the Project-A compartment for the 'A-Admins' group.

C. Allow any-user to inspect users in tenancy: This is invalid because OCI does not allow the use of "any-user" in policies. You must specify a valid group or dynamic group to define permissions.

D. Allow group 'Default'/'A-Developers' to create volumes in compartment Project-A: This is valid. It permits the 'A-Developers' group to create volumes in the Project-A compartment.
