Manual backups in Autonomous Database are stored in OCI Object Storage, and the bucket name follows a strict convention. The correct name is:

BACKUP_DBSRV1 (D):For manual backups, ADB uses a bucket named BACKUP_ (all uppercase). Here, DBSRV1 is the database’s unique name (not the display name PRODDB), so the bucket must be BACKUP_DBSRV1. This bucket is automatically created by Oracle when you initiate a manual backup via the OCI console (e.g., “Create Manual Backup” button) or API (e.g., oci db autonomous-database backup create). For example, backing up DBSRV1 on March 18, 2025, stores files like backup_DBSRV1_20250318.dmp in this bucket. The unique name ensures uniqueness across the tenancy, as display names (e.g., PRODDB) might not be unique but the DB_UNIQUE_NAME is system-assigned and distinct.

The incorrect options are:

backup_proddb (A):This uses the display name proddb and lowercase, violating the BACKUP_ uppercase convention.

BACKUP_PRODDB (B):While uppercase, it uses the display name PRODDB, not the unique name DBSRV1, so it’s incorrect. Display names are for human readability, not system identification.

backup_dbsrv1 (C):This uses lowercase and lacks the exact BACKUP_ prefix format, failing Oracle’s naming rule.

The rigid naming ensures consistency and automation in ADB’s backup system.

Autonomous Data Guard enhances high availability for Autonomous Database. The two true statements are:

RPO is 0 minutes for an automatic failover (C):Recovery Point Objective (RPO) measures potential data loss. With Autonomous Data Guard, the standby database is synchronously replicated with the primary, ensuring zero data loss (RPO = 0) during an automatic failover, as all transactions are mirrored in real-time.

RTO is 2 minutes for an automatic failover (E):Recovery Time Objective (RTO) measures downtime during failover. For Autonomous Data Guard, Oracle specifies an RTO of approximately 2 minutes for automatic failovers, reflecting the time to detect failure and promote the standby to primary.

The incorrect options are:

RTO and RPO are adjustable through the OCI console (A):RTO and RPO are fixed by the Autonomous Data Guard architecture and cannot be manually adjusted via the OCI console.

RPO is adjustable, but RTO is always 5 minutes (B):RPO is not adjustable (it’s 0 due to synchronous replication), and RTO is not fixed at 5 minutes; it’s typically 2 minutes for automatic failover.

RTO and RPO are 0 minutes for manual failovers (D):Manual failovers (switchovers) have an RTO greater than 0 (typically a few minutes) due to manual initiation, though RPO remains 0 with synchronous replication.

These values ensure minimal disruption and data loss.

Critical events in Autonomous Database are those requiring immediate attention due to potential security or operational impacts:

Correct Answer (D): “Admin Password Warning” is a critical event because it indicates the admin password is nearing expiration (typically within 7 days). If not updated, it could lock out administrative access, posing a security and availability risk.

Incorrect Options:

A: “Maintenance Begin” is an operational event, not critical, as it’s planned and managed by Oracle.

B: “Database Connection” is a routine activity, not an event requiring urgent action.

C: “Schedule Maintenance Warning” is informational, not critical, as it’s a precursorto planned maintenance.

The OCI Command Line Interface (CLI) provides a range of commands for managing Autonomous Database via OCI APIs. The correct answer is:

Create, Get, List, Stop, Restore (B):These are key operations supported by the OCI CLI for Autonomous Database:

Create:oci db autonomous-database create provisions a new ADB instance.

Get:oci db autonomous-database get retrieves details of a specific ADB.

List:oci db autonomous-database list lists all ADBs in a compartment.

Stop:oci db autonomous-database stop halts the database.

Restore:oci db autonomous-database restore restores from a backup.

The incorrect options are:

A (Start, Delete, Update, Query, Stop):“Query” is not a CLI command; “Delete” and “Update” are valid but not part of this specific subset.

C (Create, Query, Update, List, Start):“Query” is invalid; “Update” is supported but not listed here.

D (Create, Query, List, Stop, Restore):“Query” is not a valid CLI operation.

This subset reflects common management tasks via CLI.
