Which THREE of the following are valid lifecycle policy actions?
Valid action.
Why this answer
Delete, Archive, and aborting multipart uploads are valid.
Which TWO features are supported by OCI File Storage Service (FSS)? (Choose two.)
FSS file systems can be encrypted using keys managed in OCI Key Management.
Why this answer
OCI File Storage Service supports snapshots for data protection and encryption using customer-managed keys via OCI KMS.
Which TWO of the following can prevent a bucket from being deleted?
Non-empty buckets cannot be deleted.
Why this answer
Retention rules and non-empty status prevent bucket deletion.
A company requires an extremely low-cost storage solution for data archiving that is rarely accessed, with a retrieval time requirement of within an hour. Which OCI storage tier should be used?
Archive Storage is specifically designed for long-term backup and data archival at the lowest cost.
Why this answer
OCI Archive Storage provides the lowest cost per gigabyte for long-term data retention, with a standard time-to-first-byte retrieval SLA of within one hour.
What is the default replication method for Object Storage buckets?
Data is automatically replicated for durability.
Why this answer
Object Storage data is automatically replicated across three Fault Domains within an AD.
Which THREE statements are true regarding OCI Object Storage architecture and data durability? (Choose three.)
OCI computes MD5 checksums to ensure data integrity during transit and storage.
Why this answer
OCI Object Storage is designed for high durability, stores data redundantly across availability domains or fault domains, and supports strong consistency for all operations.
What is the main advantage of the OCI Block Volume performance tier selection?
This allows fine-tuning for application needs.
Why this answer
Performance tiers allow users to balance cost and performance for specific workloads.
You need to share a block volume across multiple compute instances. Which configuration is required?
Block volumes are restricted to one instance at a time.
Why this answer
Block volumes do not support multi-attach. You must use a network file system instead.
You are configuring an Object Storage bucket and want to ensure that if an object is accidentally overwritten or deleted, previous versions can still be retrieved. Which feature should you enable?
Object Versioning keeps historical versions of objects when they are modified or deleted.
Why this answer
Object Versioning preserves multiple variants of an object in the same bucket, protecting against accidental overwrites and deletions.
Which TWO of the following are valid Object Storage tiers in OCI?
Archive is the low-cost tier.
Why this answer
Standard and Archive are the primary tiers in OCI Object Storage.
Which OCI Object Storage feature enables users without an OCI account to securely download or upload a specific object via a generated URL with a defined expiration time?
PAR allows generating time-bound URLs for downloading or uploading objects without credentials.
Why this answer
Pre-authenticated requests (PAR) provide a way to let users securely access or upload a specific object or bucket without requiring credentials, using a unique URL with an expiration time.
Which OCI service provides a POSIX-compliant file system?
FSS is fully POSIX-compliant.
Why this answer
File Storage Service provides a standard NFS-based, POSIX-compliant file system.
Which THREE components are involved in OCI File Storage Service?
The path mapping.
Why this answer
File systems, mount targets, and exports are the main components.
Which THREE actions can you perform on a block volume?
Resizing is supported.
Why this answer
Backups, clones, and resizing are common operations for block volumes.
What is the maximum size of a single object that can be uploaded to OCI Object Storage using a single PUT request?
Wait, the maximum size for a single PUT object upload is 50 GiB, while the total object size using multipart upload can reach 10 TiB. Let's ensure precision. Single PUT request limit is 50 GiB.
Why this answer
For standard single PUT operations, the maximum object size is 50 GiB. Larger files require multipart uploads.
Which file system protocol does OCI File Storage Service support?
FSS supports NFSv3.
Why this answer
FSS is based on the NFSv3 protocol.
You are troubleshooting an issue where an application cannot access an OCI Object Storage bucket. The IAM policies are verified as correct, and the object storage endpoint is reachable. However, the client receives HTTP 403 Forbidden errors when attempting to perform a GET request. The bucket is private. What could be causing this?
If the encryption key protecting the bucket's objects is disabled, read and write operations will fail with authorization or forbidden errors.
Why this answer
If a bucket is private and public access is blocked or IAM policies check out, pre-authenticated requests (PAR) or missing object-read permissions, or VCN Service Gateway restrictions could cause 403 errors. Another common cause is customer-managed encryption key state changes (e.g., the KMS key was disabled).
Which THREE factors influence Block Volume performance?
Shape limits bandwidth.
Why this answer
Volume size, performance tier, and instance attachment affect throughput and IOPS.
You need to increase the size of an existing Block Volume. What is the correct procedure?
Resizing increases the volume capacity dynamically.
Why this answer
You can increase the size of a volume without detaching it, then expand the file system on the OS.
Which THREE of the following operations are supported by OCI Vault in the context of storage?
Vault manages keys for Block volumes.
Why this answer
Encrypting buckets, block volumes, and file systems.
If you detach a Block Volume, what happens to the data?
Block volumes are persistent independent of compute.
Why this answer
Detaching a volume does not affect the data stored on it; it remains persistent.
Which THREE are characteristics of Object Storage lifecycle rules?
The system runs rules in the background.
Why this answer
JSON-based, filterable by name, and target-specific actions.
Which TWO are common performance issues for Block Volumes?
Exceeding tier limits causes latency.
Why this answer
Network congestion and excessive IOPS exceeding the limit are common.
What is the maximum number of volumes you can attach to a single compute instance?
Most shapes support up to 32 attachments.
Why this answer
The limit depends on the compute shape, but there is a defined maximum for block volumes.
