I have made a list of notes which helped me during my preparation for OCI Foundations 2020 Associate (1Z0-1085-20). Do run past them just before your exam for a quick revision.
- Resources can be moved from one compartment to another.
- Each OCI resource belongs to a single compartment
- An application in OCI needing the highest level of availability and resilience can be achieved by deploying the application across multiple Regions and Availability Domains.
- Dynamic Routing Gateway serves to enable connect to OCI compute instances to connect to on-premises environments.
- Resources and compartements can be added and deleted any time.
- If OCI virtual machine instances are run on OCI Dedicated virtual host, the dedicaed virtual machine host and the boot volumes of each instance will be billed.
- Standard OCI Compute shape does not incur instance billing in a STOPPED state.
- OCI service would use Public Load Balancer to distribute traffic between a set of web servers.
- OCI capability of Fault Domains can be used to protech against power failures within an Availability Domain
- Compartements can be nested
- Shared File System in OCi would be able to be delivered by File Storage
- Compute Instance in OCI always gets a private IP address
- Managed RAC Offering in OCI is
- OCI Instance always gets a private IP address
- Compute instance vertical scaling means changing to a larger or smaller shape
- Security of data center facilities is Oracle’s responsibility according to OCI shared security model.
- VM DB Systems Managed Database Service having RAC feature offering in OCI,
- Network Bandwidth is proportional to the OCPU’s in the instance shape, this is how total network throughput is allocated to a Virtual Machine
- Key Management is a security service offered by OCI.
- Local NVME does not provide for Encryption for data at rest.
- OCI Compute shapes does not incur instance billing in a stopped state.
- Operating System is managed in an IAAS offering
- With regards to the OCI Compute Service, you can launch either virtual machines or bare metal machines.
- OCI Exadata DB Systems provides the best performance for running OLTP workloads in OCI
- Transferring data across regions and data egress to the Internet are the two situations which incur costs with OCI.
