Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

OCI Network Path Analyzer. OCI Network Path Analyzer is a diagnostic tool that analyzes network reachability between two endpoints in your VCN, checking route tables, security lists, and NSGs to determine if traffic can flow.

Answer

NAT Gateway packet tracer

Answer

OCI Load Balancer health check

Answer

Service Gateway connectivity tester

Question 2

Your development team needs instances residing in a private subnet to download software patches and updates from the Oracle Cloud Infrastructure (OCI) Object Storage service without exposing those instances to the public internet. Which gateway should you configure?

Accepted Answer

Service Gateway. A Service Gateway routes traffic from a VCN to supported Oracle services, such as Object Storage, within the Oracle network fabric without going over the public internet.

Answer

Internet Gateway

Answer

NAT Gateway

Answer

Local Peering Gateway

Question 3

You have an OCI alarm that is stuck in the 'Firing' state. What is the most likely cause?

Accepted Answer

The metric data is still above the threshold. If the metric evaluation remains above the threshold, the alarm will stay in the firing state.

Answer

The alarm is paused

Answer

The notification topic is disabled

Answer

The notification frequency is too high

Question 4

An organization requires that all data uploaded to an Object Storage bucket must be automatically encrypted using a master encryption key managed by them in OCI Key Management (KMS), rather than Oracle-managed keys. How can this be enforced?

Accepted Answer

Configure the bucket during creation to use a Customer-Managed Key from OCI KMS.. When creating a bucket, you can select 'Use Customer-Managed Keys' and choose your vault and master encryption key from OCI KMS.

Answer

Apply an IAM policy stating that all PutObject API calls must pass customer secret keys in the header.

Answer

Enable SSE-C (Server-Side Encryption with Customer-Provided Keys) on every individual file upload via CLI.

Answer

Write a custom OCI Functions script triggered by Object Storage events to re-encrypt objects using KMS.

Question 5

Which type of storage is required for Boot Volumes?

Accepted Answer

Block Volume. Boot volumes are special block volumes used to boot compute instances.

Answer

File Storage

Answer

Object Storage

Answer

Ephemeral Storage

Question 6

You are using Storage Gateway to connect on-premises applications to OCI. How are file systems mapped?

Accepted Answer

Maps to Object Storage buckets. Storage Gateway maps local file systems to OCI Object Storage buckets.

Answer

Maps to Block Volumes

Answer

Maps to File Storage targets

Answer

Maps to Archive Storage only

Question 7

Which THREE features are supported by OCI Object Storage buckets?

Accepted Answer

Object versioning to retain multiple variants of an object in the same bucket.. OCI Object Storage supports customer-managed encryption keys via Vault, cross-region replication, and versioning to protect against accidental overwrites or deletions.

Answer

Direct attachment to a Linux compute instance as a block storage device formatted with ext4.

Answer

POSIX-compliant file locking for multi-client NFS v3/v4 mounts directly from the bucket.

Question 8

You need to perform a backup of a production Block Volume. What is the recommended strategy to ensure data consistency?

Accepted Answer

Block Volume Backup. Creating a volume group backup or a block volume backup ensures point-in-time consistency.

Answer

RAID 0 striping

Answer

Object Storage replication

Answer

Manual file copy via SSH

Question 9

How can you ensure that data in an Object Storage bucket remains unchanged for a specific period?

Accepted Answer

Retention Rules. Retention rules on a bucket prevent modifications or deletions for a defined duration.

Answer

Encryption

Answer

IAM policies

Answer

Lifecycle policies

Question 10

You are configuring a Lifecycle Policy for an Object Storage bucket. You want to automatically move objects older than 30 days to Archive Storage. What is the correct rule configuration?

Accepted Answer

Use the 'Archive' action with a 30-day threshold.. The lifecycle policy uses JSON-based rules to define action, name filter, and age threshold.

Answer

Use the 'Delete' action with a 30-day threshold.

Answer

Use the 'Move' action to a new bucket.

Answer

Use the 'Restore' action.

Question 11

Which tool provides a graphical way to manage Object Storage lifecycle policies?

Accepted Answer

Web Console. The OCI Web Console provides the interface for lifecycle policy management.

Answer

OCI CLI

Answer

API Explorer

Answer

Terraform

Question 12

An administrator is planning an Object Storage data archiving strategy. Which THREE characteristics apply to OCI Archive Storage? (Choose three.)

Accepted Answer

It has a minimum storage duration commitment of 90 days.. Archive Storage is designed for long-term retention, offers the lowest storage cost, and requires data to be restored to the Infrequent Access or Standard tier before reading, with a restoration latency of up to 4 hours.

Answer

Objects in Archive Storage can be read directly via GET requests without prior restoration.

Answer

It supports instant sub-second retrieval times for disaster recovery testing.

Question 13

Which TWO are common use cases for Archive Storage?

Accepted Answer

Regulatory data archiving. Long-term regulatory compliance and data backups are standard use cases.

Answer

Real-time streaming

Answer

Frequent website access

Answer

Active database logs

Question 14

Which THREE of these are OCI storage services?

Answer

Database storage

Answer

Compute storage

Question 15

Which THREE factors influence Block Volume performance?

Accepted Answer

Instance shape. Volume size, performance tier, and instance attachment affect throughput and IOPS.

Answer

Object versioning

Answer

Bucket replication setting

Question 16

Which storage type offers the highest performance for random I/O operations?

Answer

Archive Storage

Answer
