The explanation is that preemptible instances are VM instances that offer lower costs than regular instances but can be reclaimed by OCI at any time due to capacity constraints or after running for a maximum of 24 hours. Preemptible instances are ideal for short-lived and stateless workloads that can tolerate interruptions and do not require guaranteed availability or performance. Preemptible instances are billed by the second at a fixed rate that is lower than regular instances.

Exadata Virtual Machine is not a valid option for an OCI compute shape. Exadata Virtual Machine is a deployment option for Exadata Cloud Service or Exadata Cloud@Customer, which are services that provide dedicated Exadata infrastructure for running Oracle databases in OCI. Exadata Virtual Machine allows you to create multiple virtual machines on each Exadata compute node and isolate them from each other using Oracle VM technology. The valid options for OCI compute shapes are:

• Bare Metal: A bare metal instance is a physical server that gives you direct access to the underlying hardware and full isolation from other tenants.
• Dedicated Virtual Machine Host: A dedicated virtual machine host is a physical server that hosts only your virtual machine instances and no other tenant’s instances.
• Virtual Machine: A virtual machine instance is a virtual server that runs on a shared physical server with other tenants’ instances.
• Burstable: A burstable instance is a virtual machine instance that has a baseline utilization of either 12% or 50% of each CPU core and can burst above the baseline when needed.

 Generating Auth Tokens to enable instances in the dynamic group to authenticate with APIs is not a necessary step to complete this set up. This is because Auth Tokens are used to authenticate users, not instances, when making API calls to OCI services. Instance principals are a feature that allows instances to authenticate themselves using certificates, without requiring user credentials or Auth Tokens. The other options are necessary steps to complete this set up, as they enable instances in the dynamic group to make API calls against services using instance principals and IAM policies.

The explanation is that geolocation is a type of Traffic Management Steering Policy that allows you to distribute DNS traffic to different endpoints based on the location of the end user. Geolocation steering policies use geolocation data from third-party providers to map end user IP addresses to geographic regions. You can create rules that specify which endpoints to serve for each region or country, or use a default endpoint for unspecified regions.
