1Z0-931-25 Practice Questions

Oracle recommends best practices for effective alarm management:

Correct Answer (A): Suppress alarms during investigations prevents notification overload while

troubleshooting, focusing attention on the issue.

Correct Answer (C): Select the correct alarm interval for your metric ensures timely alerts without

excessive noise (e.g., 1-minute intervals for critical metrics).

Correct Answer (D): Routinely tune your alarms adjusts thresholds and settings to match workload

changes, maintaining relevance.

Incorrect Option:

B: Creating multiple alarm metrics isn’t explicitly recommended; quality and tuning of alarms matter

more than quantity.

These practices optimize monitoring efficiency.

Oracle Data Safe enhances database security across various deployments. Let’s evaluate:

A: True. Data Safe assesses cloud database configurations for vulnerabilities.

B: True. It evaluates user authentication, types, and password policies.

C: False. Data Safe supports Autonomous Databases, Exadata Cloud Service, OCI VMs, and on-

premises Oracle databases, not just Autonomous Databases.

D: True. It scans data and metadata to identify sensitive information.

Option C is the false statement, as Data Safe’s scope extends beyond Autonomous Databases.

Oracle APEX (Application Express) in Autonomous Database requires a workspace for development:

Correct Answer (A): “Access the APEX Administrator Services and create the workspace for the

developer” is the correct step. As an admin, you log into the APEX Administration Services (via

Database Actions or a direct URL), navigate to “Manage Workspaces,” and create a new workspace,

assigning it to the developer with a schema and credentials.

Incorrect Options:

B: Creating an IDCS (Identity Cloud Service) user with an APEX role manages authentication but

doesn’t create a workspace.

C: A database user with an APEX role lacks a workspace; it’s a prerequisite step, not the solution.

D: “Create a new developer account” is vague and doesn’t specify the APEX workspace creation

process.

This ensures the developer has a dedicated environment for building applications.

Monitoring Autonomous Database on Dedicated Infrastructure involves specific tools:

Correct Answer (C): Enterprise Manager Cloud Control provides comprehensive monitoring of OCI

resources, including CPU, memory, I/O, and SQL performance for dedicated deployments.

Correct Answer (D): OCI Metrics offers detailed metrics via the OCI Monitoring service, allowing

custom dashboards and alerts for key performance indicators (e.g., OCPU usage, storage).

Correct Answer (E): Performance Hub is a built-in tool in Autonomous Database for analyzing

historical performance data, identifying trends, and troubleshooting issues.

Incorrect Options:

A: RMAN (Recovery Manager) is for backup and recovery, not real-time monitoring of usage or

activities.

B: Logs provide diagnostic data but are not a standalone monitoring tool; they require manual

analysis or integration with other tools.

These tools collectively enable proactive management and optimization.

ADW and ATP are tailored for different workloads:

Correct Answer (C): “Only ADW uses columnar compression by default” is true. ADW employs Hybrid

Columnar Compression (HCC) for analytics, optimizing storage and query performance, while ATP

uses row-based storage for transactional workloads (though HCC can be enabled manually).

Incorrect Options:

A: Both ADW and ATP manage optimizer statistics automatically.

B: Autoscaling is supported by both ADW and ATP.

D: Automatic backups are standard for both.

This reflects their design focus: ADW for analytics, ATP for transactions.

Private endpoints enhance security for Autonomous Database:

Correct Answer (A): “A Network Security Group is required within your Virtual Cloud Network before

you can provision a shared Autonomous Database to use private endpoints” is true. An NSG is

mandatory to define ingress/egress rules for the private subnet hosting the endpoint.

Correct Answer (C): “Private endpoints can be configured when you clone a shared Autonomous

Database that was initially created with public endpoints” is true. Cloning allows switching to a

private endpoint configuration.

Incorrect Options:

B: Private endpoints are inaccessible from the public internet, even with ACLs; that’s their purpose.

D: Always Free tier doesn’t support private endpoints; it’s limited to public access.

This ensures isolated, secure connectivity.

Application Continuity ensures seamless failover for applications:

Correct Answer (B): EXEC DBMS_CLOUD_ADMIN.ENABLE_APP_CONT(''); is the

correct command for Autonomous Database on Shared Infrastructure. It enables Application

Continuity for a specific service (e.g., tpurgent), leveraging the DBMS_CLOUD_ADMIN package

designed for cloud-specific administration.

Incorrect Options:

A: ALTER SESSION only affects the current session, not persistent database-wide settings.

C, D: ALTER DATABASE and ALTER SYSTEM are not supported in Autonomous Database’s managed

environment; Oracle restricts such commands.

This ensures application resilience in a managed setup.

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 precursor to planned

maintenance.

E: “New Maintenance Schedule” is administrative, not an immediate threat.

This ensures timely response to security-critical situations.

Full Detailed In-Depth Explanation:

The DBMS_CLOUD package facilitates cloud integration:

A: True. CREATE_EXTERNAL_TABLE creates external tables for querying cloud data directly.

B: False. No DELETE_FILE procedure exists; credential management uses DROP_CREDENTIAL.

C: True. CREATE_CREDENTIAL securely stores cloud storage credentials.

D: True. VALIDATE_EXTERNAL_TABLE checks file integrity and logs errors.

E: False. PUT_OBJECT uploads files to cloud storage, not into the database.

Performance Hub in Autonomous Database provides performance monitoring insights. The correct

answer is:

24 Hours (C): When you open Performance Hub in the OCI console or Database Actions, the default

time range displayed is the last 24 hours, shown in Coordinated Universal Time (UTC). This allows

users to review recent performance metrics like CPU usage, SQL activity, and wait times. Users can

adjust this range (e.g., to 1 hour or 1 week) as needed.

The incorrect options are:

15 Minutes (A): This is not a default option; it’s too short for a broad performance overview.

1 Hour (B): Available as an option, but not the default setting.

1 Week (D): Also available, but not the default; it’s a longer-term view users can select manually.

The 24-hour default balances recency and context for performance analysis.
