OCI FOUNDATIONS EVALUATION EXAMS 2025/2026
QUESTIONS WITH ANSWERS RATED A+
✔✔What is Dedicated VM Hosts - ✔✔-Run your VMs instances on dedicated bare metal
servers (single-tenant VMs)
-Gives you access to the whole box - no other customer will be on the same box
Allows max security
✔✔Uses cases for VMs - ✔✔-Use VMs when you want to control all aspects of an
environment
-Use VMs when you want to deploy a legacy app running on windows or Linux
-Use VMs to move apps from on-premise to OCI
✔✔What makes up a compute instance - ✔✔-Compute instances depend on other OCI
services such as Block Volume & VCN
-Boot Volume (OS disk)
-Block Volume (data disks)
-VCN
✔✔Boot Volume - ✔✔-(OS disk) - type of block volume
-OS is kept here
✔✔Block Volume - ✔✔-Data Disk
-Data resides here
-Hard drive in a server that is installed in a remote chassis
-Data is typically stored on device in fixed sized blocks (ex. 512 bytes)
-Apps/file systems decide how blocks are combined and accessed
✔✔VCN - ✔✔-Virtual Cloud Network
-Software defined private network that you set up in OCI
-Enables OCI resources such as compute instances to securely communicate with
Internet, other instances or on-premises data centers
-Lives within an OCI region
-Highly available, scalable, and secure
✔✔Container Engine - ✔✔-Customer manages:
□ Code
□ App Container
-Include the app & all of its dependencies, but share the kernel/OS with other
containers.
-Containers aren't tied to any specific infrastructure & can run anywhere
✔✔How do you deploy container engines? - ✔✔-Manually SSH into machines & run
Docker
-Scripting or config management tools
, -Orchestration systems
✔✔Manually SSH into machines & run Docker Pros & Cons - ✔✔Pro: simple & easily
understood
Con: Not automated, no reproductible, doesn't scale, doesn't self heal
✔✔Scripting or config management tools Pros & Cons - ✔✔Pro: integrates with existing
environments, easily understood
Con: doesn't scale, doesn't self heal, no scheduling mechanism
✔✔Orchestration Systems Pros & Cons - ✔✔Pro: automated, reproducible, self-
healing, scalable
Con: additional tooling and training required, some overhead
Kubernetes is an example
✔✔Kubernetes - ✔✔An open source system for automating deployment, scaling &
management of containerized apps
-OKE is a fully, managed, scalable, and highly available service that you can use to
deploy your containerized apps in OCI
-OCIR is managed Docker container registry service and can be used to pull images for
K8s deployments
✔✔Functions - ✔✔-Customer Manages: Code
-Small but powerful blocks of code that generally do one simple thing
-Stored as Docker images in a specified Docker registry
Invoked in response to a CLI command or signed HTTP request
-Consumption based- Push container to registry, configure function trigger, code runs
only when triggered - pay for code when triggered
✔✔Types of Storage - ✔✔-Block
-Local NVMe
-Object
-File
✔✔Use Cases for Block Storage - ✔✔Databases
Exchange
Vmware - VMFS
Server boot
✔✔Highly Durable definition of Block storage - ✔✔-Persistent
-Block Volume stores replica data in 3 separate Fault Domains
-You don't need to configure any software based protection
-To minimize loss of data due to deletes or corruption, we recommend to take periodic
backups of block volumes. OCI allows automated, scheduled backups -Backups are
stored in Object storage
