Question 1

Which THREE features are supported by Oracle Base Database Service on virtual machines? (Choose three.)

Accepted Answer

Automated daily and weekly backups to OCI Object Storage. Base Database Service on VMs supports Data Guard, automated backups, database edition changes (e.g., Enterprise to High Performance), and custom DB systems.

Answer

Automatic zero-downtime shard migration across tenants

Answer

Automatic scaling of physical server hardware racks

Question 2

You need to migrate a Windows Server boot volume containing sensitive application data across regions in OCI. What is the recommended and most secure sequence of steps?

Accepted Answer

Create a custom image from the instance, export the image to an Object Storage bucket, copy the bucket to the target region, and import the image in the target region.. To move a boot volume or custom image across regions, you create a custom image from the boot volume, export it to an Object Storage bucket, copy the Object Storage bucket or export the custom image directly across regions, and then import it in the destination region.

Answer

Use the OCI Database Migration service to copy the operating system boot sectors.

Answer

Detach the boot volume, attach it to a secondary compute instance, and use rsync over a VCN remote peering connection.

Answer

Create a block volume backup, copy the backup directly to the destination region using the native backup copy feature, and restore it as a boot volume.

Question 3

You need to restore an Oracle Base Database System to a specific point in time using incremental backups and archived redo logs. Which tool should you use at the OS level if you are managing the recovery manually?

Accepted Answer

Oracle Recovery Manager (RMAN). Oracle Recovery Manager (RMAN) is the standard Oracle tool used for backup, restoration, and recovery of database files including datafiles, control files, and archived redo logs.

Answer

Data Pump (impdp)

Answer

OCI Block Storage Volume Snapshots

Answer

SQL*Loader

Question 4

You are managing an Oracle Base Database System and need to patch the database home and operating system. Which utility is provided by Oracle in OCI to automate and orchestrate database patching safely?

Accepted Answer

OCI Database Management Service and Console Patching workflow. OCI provides built-in database management tools, specifically the OCI Console workflow and DBaaS CLI (dbaascli), to apply database and grid infrastructure patches.

Answer

Autonomous Patching Daemon (autopatchd)

Answer

Oracle Enterprise Manager Cloud Control Cloud Agent only

Answer

YUM Package Manager

Question 5

What is the maximum number of compartments you can nest within a single parent compartment in OCI?

Accepted Answer

6 levels. OCI supports nesting compartments up to 6 levels deep beneath the root compartment (tenancy).

Answer

Unlimited

Answer

2 levels

Answer

10 levels

Question 6

You are migrating an on-premises virtual machine image in QCOW2 format to OCI. Before you can launch compute instances from this image in OCI, what must you do with the file?

Accepted Answer

Upload the image to an Object Storage bucket and import it as a custom image.. Custom images in QCOW2 or RAW format must be uploaded to an OCI Object Storage bucket, and then imported as a custom image using the OCI Console or CLI.

Answer

Convert the file to an ISO and mount it using the OCI Console virtual console.

Answer

Attach the QCOW2 file to a VCN subnet as a storage gateway resource.

Answer

Upload the QCOW2 file directly to a compute instance boot volume via SSH.

Question 7

You have an existing compute instance with a standard boot volume size of 47 GB. Your application requires 200 GB. You successfully increase the boot volume size to 200 GB in the OCI Console. However, when you run `df -h` inside the guest OS, it still shows 47 GB. What is the cause?

Accepted Answer

The guest OS partition and file system have not yet been resized to claim the expanded storage.. While OCI resizes the physical storage block device at the hypervisor level, the guest operating system partition and file system must be manually or automatically extended to utilize the new space.

Answer

OCI does not support expanding boot volumes online; you must reboot the instance.

Answer

You must detach the boot volume and reattach it for the OS to notice the change.

Answer

Boot volumes have a hard cap of 50 GB unless converted to Block Volumes.

Question 8

You are deploying a microservices application on OKE and want to implement zero-downtime rolling deployments for your pods. Which Kubernetes deployment strategy and configuration parameter should you utilize?

Accepted Answer

RollingUpdate strategy with maxSurge and maxUnavailable configured. Kubernetes deployments support `RollingUpdate` strategy with parameters like `maxSurge` and `maxUnavailable` to control how pods are replaced during updates without downtime.

Answer

Horizontal Pod Autoscaler with metric-based CPU triggers

Answer

Static Pod assignment via node selectors

Answer

Recreate strategy with immediate termination of all old pods

Question 9

Which TWO of the following statements regarding OCI Instance Configurations and Instance Pools are correct? (Choose two.)

Accepted Answer

An instance configuration defines the blueprint (shape, image, metadata) used to provision instances in an instance pool.. Instance configurations act as templates for creating instance pools, and instance pools can be scaled manually or automatically via autoscaling configurations.

Answer

Instance configurations can only be created from scratch using JSON templates, never from an existing running instance.

Answer

Instance pools can only contain instances of different shapes and operating systems.

Answer

Autoscaling policies cannot be attached to instance pools.

Question 10

You are managing an OKE cluster and need to inspect application container logs that are written to stdout/stderr by pods running on worker nodes. What is the standard kubectl command to view these logs?

Accepted Answer

kubectl logs . `kubectl logs ` is the standard command to retrieve container logs from stdout/stderr in a Kubernetes cluster.

Answer

kubectl get events

Answer

kubectl describe pod

Answer

oci compute instance list-logs

Question 11

Which TWO of the following are valid deployment models for Oracle Autonomous Database in OCI?

Answer

Autonomous Database on Standalone Bare Metal VM

Question 12

An administrator needs to scale up CPU cores for an existing Oracle Autonomous Transaction Processing database without causing application downtime. Which feature of Autonomous Database allows this?

Accepted Answer

Autonomous Database Elastic Resource Scaling. Autonomous Database supports online scaling of both CPU OCPUs and storage capacity without interrupting running workloads.

Answer

Database migration via Oracle Zero Downtime Migration tool

Answer

Manual resizing through operating system configuration files

Answer

Database cloning

Question 13

What is the primary function of the OCI Compute Instance Oracle Cloud Agent?

Accepted Answer

To perform plugin-based management tasks like monitoring, patching, and run commands on the instance.. Oracle Cloud Agent is a lightweight process that runs on instances to manage administrative tasks such as collecting monitoring metrics, executing run commands, and managing OS patches.

Answer

Question 14

When creating an OCI Function application, you must select one or more subnets. What type of subnets should you choose if your function needs to call external public APIs over the internet?

Accepted Answer

Subnets associated with a NAT Gateway or Internet Gateway route table. If functions need outbound internet access (e.g., calling public APIs), the associated subnets must have a route table pointing to a NAT Gateway or Internet Gateway.

Answer

Subnets with a Service Gateway only

Answer

Subnets configured strictly as local peering endpoints

Answer

Subnets with no route table entries

Question 15

You want to automate the installation of packages and configuration scripts on newly launched compute instances without manual intervention. What OCI feature should you use?
