Question 1

You have a large dataset in Object Storage that needs to be accessed by an on-premises server. What is the most efficient way to access this data via a local file interface?

Accepted Answer

Use Storage Gateway. Storage Gateway provides a file-system interface to Object Storage.

Answer

Use Mount Targets

Answer

Use OCI CLI to download everything

Answer

Use FastConnect alone

Question 2

You are migrating a database that requires a consistent point-in-time snapshot of multiple volumes. What should you use?

Accepted Answer

Volume Groups. Volume Groups allow you to group multiple volumes for consistent, cross-volume snapshots.

Answer

Individual volume backups

Answer

Storage Gateway

Answer

Object Storage replication

Answer

Clone the volumes

Question 3

Which OCI storage service is best suited for hosting shared configuration files and home directories for hundreds of Linux compute instances simultaneously using the NFSv3 protocol?

Accepted Answer

OCI File Storage Service. File Storage Service (FSS) provides a distributed, scalable, enterprise-grade network file system that supports the NFSv3 protocol for concurrent access from multiple instances.

Answer

OCI Object Storage

Answer

OCI Archive Storage

Answer

OCI Block Volume

Question 4

How do you ensure data integrity for uploads to Object Storage?

Accepted Answer

MD5 checksum. Using MD5 hashing ensures the object was not corrupted during transit.

Answer

Encryption

Answer

Versioning

Answer

HTTPS

Question 5

An administrator wants to create a point-in-time, space-efficient replica of an existing Block Volume within the same availability domain. Which feature should be used to achieve this instantly?

Accepted Answer

Block Volume Clone. Block Volume clones allow you to create an instant, point-in-time, replica of a block volume within the same availability domain without needing to create a full backup first.

Answer

Block Volume Backup

Answer

Cross-Region Replication

Answer

Volume Group Backup

Question 6

An administrator created a file system using the File Storage Service (FSS) and needs to control access from specific compute instances using Network Security Groups (NSGs) and security lists. Which component of FSS must be configured to enforce network-level security and access permissions?

Accepted Answer

Mount Target Export Options. Export options are used in File Storage Service to control access to file systems from mount targets, allowing restriction by source IP addresses, virtual cloud networks, and root squashing privileges.

Answer

Volume Group Backup Policy

Answer

IAM Dynamic Groups

Answer

Bucket Access Policy

Question 7

Which TWO of the following statements about Storage Gateway are accurate?

Accepted Answer

It converts files to objects. It converts files to objects and uses a local cache for performance.

Answer

It performs automatic compression

Answer

It provides POSIX support

Answer

It is a block-level device

Question 8

If you detach a Block Volume, what happens to the data?

Accepted Answer

Data remains intact. Detaching a volume does not affect the data stored on it; it remains persistent.

Answer

Data is lost if not backed up

Answer

Data is encrypted for migration

Answer

Data is deleted

Question 9

You are setting up a File Storage mount target. What is required at the subnet level?

Accepted Answer

An IP address within the subnet. Mount targets require a specific mount target IP and security rule access.

Answer

A NAT Gateway

Answer

A Public IP

Answer

A Service Gateway

Question 10

Which type of compute shape provides the lowest cost per core for general-purpose workloads by utilizing ARM-based Ampere processors?

Accepted Answer

VM.Standard.A1.Flex. OCI Ampere A1 Compute shapes (VM.Standard.A1.Flex) use ARM processors and offer high power efficiency and cost-effectiveness for scale-out workloads.

Answer

VM.Standard.E4.Flex

Answer

BM.DenseIO2.52

Answer

VM.Standard3.Flex

Question 11

You manage an instance pool backed by an autoscaling configuration. The pool reaches its maximum limit of 10 instances due to a traffic spike. A hardware maintenance event triggers a retirement notification for one of the instances in the pool. How does OCI Instance Pools with Autoscaling handle this retired instance?

Accepted Answer

The instance is replaced automatically by the instance pool to maintain the operational state, managing lifecycle events independently of active autoscaling metrics.. Instance pools automatically replace unhealthy or retired instances to maintain the desired capacity. If an instance is retired, the pool provisions a new instance to replace it, even if autoscaling has reached its maximum size, because minimum/desired capacity rules take precedence over instance retirement recovery.

Answer

The instance is terminated, and a new instance is provisioned to replace it, temporarily exceeding the maximum limit if necessary until scaling rules scale it back down.

Answer

The instance is terminated and not replaced because the pool is already at its maximum limit.

Answer

The autoscaling configuration must be manually edited to increase the max limit before the instance can be replaced.

Question 12

You want to deploy an OCI Function and test it locally on your developer workstation before pushing it to Oracle Functions Registry. Which command in the fn CLI initializes a new function project template?

Accepted Answer

fn init. `fn init` initializes a new function boilerplate with runtime configuration and metadata files (like `func.yaml`).

Answer

fn deploy --local

Answer

fn build local

Answer

fn create function

Question 13

Which TWO actions should you take to troubleshoot an OCI compute instance that has become completely unresponsive and unreachable over SSH? (Choose two.)

Accepted Answer

Access the instance via the Serial Console connection to inspect system logs and kernel messages.. When an instance is unreachable over SSH, you can use the Serial Console to view boot logs and interactive terminal prompts, or check instance metrics in OCI Monitoring.

Answer

Delete the VCN and recreate all networking subnets.

Answer

Log into the physical data center and connect a physical keyboard to the server rack.

Answer

Reinstall the OCI tenancy IAM security policies.

Question 14

Which THREE actions should you take when preparing a custom Linux VM image for export and import across OCI tenancies or regions? (Choose three.)

Accepted Answer

Remove persistent network interface rules (such as udev network interface mapping rules).. When preparing custom images for export/import, you must ensure cloud-init is installed and configured, clean up persistent network rules (like udev rules), and ensure the image is in a supported format (QCOW2 or RAW).

Answer

Embed tenancy administrator API signing keys in plaintext within `/etc/passwd`.

Answer

Format all root partitions using proprietary Windows NTFS file systems.

Question 15

An application requires an Oracle Autonomous Database that supports complex analytical queries, reporting, and high-throughput data warehousing workloads. Which workload type should you select during provisioning?
