Oracle Updated 1z0-1085-23 Exam Questions and Answers by diana

Creating a manual cluster of compute instances, and Writing custom scripts that will monitor your solution are not valid ways to ensure fault tolerance at all. Also, Performing Data Integrity check when using OCI File Storage Service is not valid since OCI takes care of it.

Therefore, we are left with:

1) Using multiple OCI Availibility Domains (AD), where available, to deploy your solution - Which is excellent because we have multiple AD's so that if one fails, we have a backup AD!

2) Ensuring your solution components are distributed across OCI Fault Domains - So that we can protect our deployment against unexpected power failures, AD failure etc.

• A compartment is a logical container that can hold OCI resources such as compute instances, block volumes, virtual cloud networks, etc. Compartments help you organize and control access to your resources based on business needs or security requirements3
• By default, your tenancy comes with a root compartment that is the parent of all other compartments in your tenancy. You cannot delete the root compartment, but you can create subcompartments within it to further organize your resources3
• Compartments can be used to logically separate OCI resources, not physically separate them. Resources within one compartment can interact with resources in other compartments, as long as the appropriate policies and network configurations are in place. For example, you can attach a compute instance in one compartment to a virtual cloud network in another compartment, or grant access to a user group in one compartment to manage resources in another compartment34
