Comprehensive cheat sheet to pass Oracle 1Z0-1085 Exam

Basic Concept:

Key benefit of using OCI --> Committed performance with predictable pricing model
You manage in an IaaS Offering --> Operating System
Horizontal scaling --> Adding additional compute instance
Vertical Scaling --> Adding more CPU or memory to an existing server
Scaling in OCI --> Scaling up or down, and scaling in or out.
Logically group and isolate OCI resources --> Compartments
Categorize multiple users into teams --> Groups
Leverages Terraform to configure infrastructure as a code --> Resource Manager
Protect against unexpected hardware or power supply failures within an availability domain --> Fault Domain.
Protect against power failures within an availability Domain --> Fault Domain
Mission critical application requires to be globally available at all time --> Use multiple fault domains in each availability domain in each region.

Storage:

key benefit of OCI Virtual Machine DB Systems --> Support for RACDB systems/Fast provisioning/ Scaleup Block Storage Anytime.
Immediate retrieval storage --> Object storage (Standard)
Lowest pricing for storage --> OCI Archive Storage
Provide a shared file system across multiple compute instance --> File Storage
Migrate old database backups from on-premises data centre to OCI --> Archive Storage

Database:

NOT available as part of OCI Free Tier --> OCI Exadata DB System
OCI Managed database offer managed Real Application Cluster (RAC) --> VM DB System
Benefit of ADW --> Scale both CPU and Storage without downtime

Establish a secure connection between an on premise data centre and OCI --> IPSec VPN
OCI service can you use to assess user security of your Oracle databases --> Oracle Data Safe
Dynamic Routing Gateway Serve --> Enables OCI Compute instance to connect to on-premises environment.
NOT part of OCI always free eligible resources --> Fast Connect (1 *** public peering)
Dedicated connection with minimal network latency from on-premises data centre to OCI --> OCI Fast-Connect
