NEW QUESTION # 11
Which statement is FALSE about setting up compartment quotas?
- A. You cannot manage quotas in a compartment unless you belong to a group that has the correct permissions.
- B. Compartment quotas cannot be set on the root compartment.
- C. Compartment quotas use policies that allow allocation of resources with a high level of flexibility.
- D. Quotas set on a parent compartment override quotas set on child compartments.
Answer: B
Explanation:
Compartment quotas in Oracle Cloud Infrastructure (OCI) manage resource allocation:
Correct Answer (D): "Compartment quotas cannot be set on the root compartment" is false. Quotas can be applied to any compartment, including the root compartment, to limit resource usage tenancy-wide. While direct quotas on the root are less common (child compartment quotas are typically used), it's technically possible via OCI policies.
True Statements:
A: Quotas offer flexible resource limits (e.g., OCPUs, storage) via policy statements.
B: Parent compartment quotas take precedence over child quotas, enforcing hierarchical control.
C: Managing quotas requires appropriate IAM permissions (e.g., manage quotas), ensuring security.
This flexibility supports granular resource management across the tenancy.

Explanation:
Full Detailed In-Depth Explanation:
Supported events:
A: True. Marks the start of maintenance.
B: False. Not a recognized event type.
C: True. Indicates compartment change start.
D: False. IORM updates are internal, not event-tracked.
E: True. Signals termination completion.
NEW QUESTION # 13
Your customer wants to permanently disable scheduled maintenance on Autonomous Dedicated Infrastructure to keep their current database version. How can they achieve this?
- A. Change the Automatic Maintenance Schedule to 'None'
- B. Change the Automatic Maintenance Schedule to 'Specify a Schedule' but do not select any month, week, or day
- C. Change the Automatic Maintenance Schedule to 'No Preference'
- D. You cannot permanently disable scheduled Automatic Maintenance
Answer: D
Explanation:
Oracle Autonomous Database on Dedicated Infrastructure enforces automatic maintenance to ensure security, stability, and performance. The correct answer is:
You cannot permanently disable scheduled Automatic Maintenance (C): Oracle mandates periodic maintenance updates (e.g., patching) to keep the database secure and compliant with the latest fixes. Customers can influence the timing of these updates but cannot disable them permanently. This is a design principle of the Autonomous Database service to reduce administrative overhead while maintaining system integrity.
The incorrect options are:
Change the Automatic Maintenance Schedule to 'No Preference' (A): This setting allows Oracle to determine the maintenance window but does not disable maintenance. It still occurs as scheduled by Oracle.
Change the Automatic Maintenance Schedule to 'None' (B): There is no 'None' option in the maintenance scheduling settings for Autonomous Dedicated Infrastructure. This is not a valid configuration.
Change the Automatic Maintenance Schedule to 'Specify a Schedule' but do not select any month, week, or day (D): This is not a functional workaround. Specifying a schedule requires selecting a valid time window, and leaving it blank does not prevent maintenance; it simply reverts to Oracle's default scheduling.
Oracle's documentation confirms that while customers can reschedule or skip specific maintenance runs (up to two consecutive quarters), permanently disabling automatic maintenance is not permitted to ensure the system remains up-to-date and secure.
NEW QUESTION # 14
Which statement is correct about the Service Console in an Autonomous Database?
- A. You can use the Service Console to manage runaway SQL statements on an Autonomous Database.
- B. You can use the Service Console to create manual backups of an Autonomous Database.
- C. You can use the Service Console to move an Autonomous Database between compartments.
- D. You can use the Service Console to enable or disable auto-scaling of an Autonomous Database.
Answer: A
Explanation:
Full Detailed In-Depth Explanation:
The Service Console is a database-specific management interface:
A: False. Auto-scaling is managed via the OCI Console, not the Service Console.
B: True. The Service Console allows monitoring and terminating runaway SQL statements that consume excessive resources.
C: False. Manual backups are created through OCI Console or SQL commands, not the Service Console.
D: False. Moving compartments is an OCI Console function, not a Service Console task.
NEW QUESTION # 15
You want to enable automatic indexing in a database, but any new auto indexes should be created as invisible indexes, so that they cannot be used in SQL statements. Which command will you use?
- A. EXEC DBMS_AUTO_INDEX.CONFIGURE('AUTO_INDEX_MODE','REPORT ONLY')
- B. EXEC DBMS_AUTO_INDEX.CONFIGURE('AUTO_INDEX_MODE','IMPLEMENT')
- C. EXEC DBMS_AUTO_INDEX.CONFIGURE('AUTO_INDEX_MODE','OFF')
- D. EXEC DBMS_AUTO_INDEX.CONFIGURE('AUTO_INDEX_MODE','INVISIBLE')
Answer: A
Explanation:
Oracle's automatic indexing feature, available in Autonomous Database, optimizes query performance by creating and managing indexes. The requirement here is to enable it but ensure new indexes are invisible (not used by the optimizer unless explicitly made visible). The correct command is:
EXEC DBMS_AUTO_INDEX.CONFIGURE('AUTO_INDEX_MODE','REPORT ONLY') (C): The REPORT ONLY mode enables automatic indexing, where the database identifies and creates candidate indexes based on workload analysis. However, these indexes are created as invisible by default, meaning the optimizer does not use them in SQL execution plans unless a DBA manually makes them visible (e.g., via ALTER INDEX ... VISIBLE). This mode is ideal for testing or validation without impacting production queries. For example, if a query frequently filters on a column, an invisible index might be created, but it won't affect performance until explicitly activated.
The incorrect options are:
EXEC DBMS_AUTO_INDEX.CONFIGURE('AUTO_INDEX_MODE','IMPLEMENT') (A): The IMPLEMENT mode fully enables automatic indexing, creating and maintaining visible indexes that the optimizer uses immediately. This contradicts the requirement for invisible indexes.
EXEC DBMS_AUTO_INDEX.CONFIGURE('AUTO_INDEX_MODE','OFF') (B): The OFF mode disables automatic indexing entirely, so no indexes (visible or invisible) are created, failing the requirement to enable it.
EXEC DBMS_AUTO_INDEX.CONFIGURE('AUTO_INDEX_MODE','INVISIBLE') (D): There is no INVISIBLE mode in DBMS_AUTO_INDEX.CONFIGURE. While indexes can be set as invisible individually, this is not a valid configuration option for the auto-indexing feature.
The REPORT ONLY mode provides a controlled approach, allowing index creation for analysis without immediate deployment. This is particularly useful in Autonomous Database, where automation is balanced with DBA oversight.
NEW QUESTION # 16
Which can be used to ensure that your Autonomous Database is accessible only from a given set of IPs?
- A. Access Control List
- B. IPSec List
- C. Security List
- D. IP Vault
Answer: A
Explanation:
Restricting access to an Autonomous Database to specific IPs involves network security controls. The correct answer is:
Access Control List (C): In Autonomous Database, an Access Control List (ACL) defines which IP addresses or CIDR blocks (e.g., 192.168.1.0/24) can connect to the database. You configure this via the OCI console under the ADB's "Access Control List" settings, adding rules like "Allow TCP from 10.0.0.0/16 on port 1522." This applies to public endpoints (shared infrastructure) or private endpoints with additional network rules, ensuring only authorized IPs can initiate connections. For example, a company might restrict access to its office VPN range, blocking all other traffic. ACLs work at the database level, complementing VCN security.
The incorrect options are:
Security List (A): Security Lists operate at the VCN subnet level, controlling traffic to all resources in the subnet (e.g., ingress TCP 1522 to an ADB subnet). While useful, they're broader than ADB-specific ACLs, which target the database instance directly, making ACLs the precise answer here.
IP Vault (B): There's no "IP Vault" in OCI. This might confuse OCI Vault (for secrets), but it doesn't manage IP access.
IPSec List (D): IPSec secures traffic via VPNs, not IP allowlisting for database access. It's unrelated to ADB connectivity restrictions.
ACLs provide a database-specific, user-friendly way to enforce IP-based access control.
NEW QUESTION # 17
Which of the following is not required for connecting to Autonomous Database (ADB) via SQL Developer?
- A. Connection Name
- B. Password
- C. Database name
- D. Service
- E. Username
Answer: A
Explanation:
Connecting to Autonomous Database (ADB) via SQL Developer requires specific parameters. The correct answer is:
Connection Name (E): The Connection Name is a user-defined label in SQL Developer to identify the connection in the tool's interface. It is not a technical requirement for establishing the database connection itself, making it optional in terms of connectivity.
The required parameters are:
Password (A): Essential for user authentication alongside the username.
Service (B): Refers to the service name (e.g., high, medium, low) from the wallet's tnsnames.ora, specifying the performance level and connection type.
Username (C): Required to identify the database user.
Database name (D): Needed to specify the target database or PDB within the ADB instance, typically provided via the wallet configuration.
Without A, B, C, and D, the connection cannot be established, but E is merely a convenience.
NEW QUESTION # 18
Which two methods can you use to create database users and grant roles in Autonomous Database services?
- A. SQL*Plus
- B. SQL Developer
- C. DBMS_CLOUDADMIN package
- D. Oracle Cloud Infrastructure (OCI) service console
Answer: A,B
Explanation:
Full Detailed In-Depth Explanation:
User and role management in Autonomous Database:
A: False. OCI console manages infrastructure, not database users.
B: True. SQL Developer provides a GUI for user/role administration.
C: False. DBMS_CLOUDADMIN is for cloud-specific tasks, not user creation.
D: True. SQL*Plus allows direct SQL commands for user/role management.
NEW QUESTION # 19
How many Network Security Groups (NSGs) can you configure for an Autonomous Database?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: B
Explanation:
Network Security Groups (NSGs) in OCI control network traffic to Autonomous Database instances:
Correct Answer (D): You can configure up to 5 NSGs for an Autonomous Database. This limit allows sufficient flexibility to define multiple security rules while maintaining manageability. NSGs can be assigned during provisioning or updated later via the OCI Console or API, restricting access to specific IP ranges or VCNs.
Incorrect Options:
A, B, C: The values 3, 9, and 7 are not documented limits for NSGs in Autonomous Database; the official limit is 5.
This capability supports secure network configurations tailored to organizational needs.
NEW QUESTION # 20
A Business Analyst joined your organization and wants to explore the database tools. When restoring or cloning an Autonomous Database (ADB), you must select a backup that is at least how old?
- A. 24 hours
- B. 5 minutes
- C. 1 day
- D. 2 hours
Answer: A
Explanation:
Full Detailed In-Depth Explanation:
When restoring or cloning an Autonomous Database (ADB), Oracle enforces a minimum backup age to ensure data consistency and integrity. The official Oracle documentation specifies that backups used for these operations must be at least 24 hours old. This requirement exists because:
Backups need time to complete and stabilize, ensuring all transactions are fully committed and the backup is consistent.
Recent backups (e.g., less than 24 hours old) may still be in progress or lack full verification, risking incomplete or corrupted restores/clones.
Options B (5 minutes), C (2 hours), and D (1 day) are either too short or redundant:
5 minutes and 2 hours: Too recent, violating the 24-hour rule.
1 day: Matches 24 hours but is less precise than the explicit "24 hours" phrasing in the documentation.
For the Business Analyst's exploration, they can access tools like SQL Developer Web or Data Load via the OCI Console under the "Tools" tab, but this question focuses on the backup age constraint, making A the best answer.
NEW QUESTION # 21
In the Autonomous Database on Dedicated Infrastructure service, what does the fleet administrator use to control OCPU utilization?
- A. SQL Developer Web Console
- B. Resource Manager settings
- C. Compartment quotas
- D. Oracle Machine Learning notebook
Answer: C
Explanation:
Fleet administrators manage resource utilization in Autonomous Database on Dedicated Infrastructure:
Correct Answer (B): Compartment quotas are used to set limits on OCPU usage across multiple database instances within a compartment. This OCI feature allows administrators to define maximum resource allocations, ensuring efficient use and cost control at a tenancy level.
Incorrect Options:
A: Oracle Machine Learning notebooks are for analytics, not resource control.
C: SQL Developer Web Console manages individual database tasks, not fleet-wide OCPU limits.
D: Resource Manager settings apply to individual instances, not fleet-level quotas.
Compartments provide a scalable, tenancy-wide control mechanism.
NEW QUESTION # 22
You have been tasked with analyzing a year's worth of sales data stored in an Autonomous Data Warehouse instance. Which tool would you use to automate data exploration and create pivot tables?
- A. SQL Developer Web
- B. Data Load
- C. APEX
- D. Business Models
Answer: D
Explanation:
Full Detailed In-Depth Explanation:
A: False. APEX is for app development, not data exploration.
B: False. SQL Developer Web is for SQL queries, not pivot tables.
C: True. Business Models in ADW automates data exploration and generates pivot tables.
D: False. Data Load is for importing data, not analysis.
NEW QUESTION # 23
Which two statements are true about Recovery Time Objective (RTO) and Recovery Point Objective (RPO) for Autonomous Data Guard? (Choose two.)
- A. RPO is adjustable, but RTO is always 5 minutes
- B. RPO is 0 minutes for an automatic failover
- C. RTO is 2 minutes for an automatic failover
- D. RTO and RPO are adjustable through the OCI console
- E. RTO and RPO are 0 minutes for manual failovers
Answer: B,C
Explanation:
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.
NEW QUESTION # 24
Which statement is true when the Autonomous Database has auto scaling enabled?
- A. Enables the database to use up to 3x CPU/IO resources immediately when needed by the workload
- B. Increases the number of sessions available to the database
- C. Scales the PGA and SGA size when needed for the workload
- D. Database concurrency is scaled up when needed by the workload
Answer: A
Explanation:
When auto scaling is enabled in Oracle Autonomous Database, it dynamically adjusts resources to handle workload demands. The correct answer is:
Enables the database to use up to 3x CPU/IO resources immediately when needed by the workload (D): Auto scaling allows the database to automatically scale its CPU and I/O resources up to three times the base number of OCPUs provisioned, without manual intervention. This ensures the database can handle sudden spikes in demand efficiently, reverting to the base level when the workload decreases. This feature applies to both Autonomous Transaction Processing (ATP) and Autonomous Data Warehouse (ADW).
The incorrect options are:
Increases the number of sessions available to the database (A): Auto scaling does not directly increase session limits; session capacity is tied to the service level (e.g., LOW, MEDIUM, HIGH) and not dynamically adjusted by auto scaling.
Scales the PGA and SGA size when needed for the workload (B): The Program Global Area (PGA) and System Global Area (SGA) are memory structures managed automatically by Oracle, but auto scaling specifically adjusts CPU and I/O resources, not memory allocation directly.
Database concurrency is scaled up when needed by the workload (C): While increased CPU/IO resources can improve concurrency indirectly, auto scaling does not explicitly manage concurrency levels; this is more related to connection service settings.
This capability enhances performance elasticity for unpredictable workloads.
NEW QUESTION # 25
Which of the following two statements regarding Data Transforms are correct? (Choose two.)
- A. Data Transforms provides access to Oracle Data Integrator (ODI) Web Edition
- B. All capabilities to transform data in ODI Classic are available with ODI Web Edition
- C. Workflows for Data Transforms are only available on the ODI Web Edition
- D. Data Transforms allows you to design data transformations in the form of data loads, data flows, and workflows
Answer: B,D
Explanation:
Data Transforms is a feature in Autonomous Database for designing data transformations. The two correct statements are:
Data Transforms allows you to design data transformations in the form of data loads, data flows, and workflows (B): True. Data Transforms provides a graphical interface to create data loads (importing data), data flows (transforming data), and workflows (sequencing operations), simplifying ETL processes within ADB.
All capabilities to transform data in ODI Classic are available with ODI Web Edition (D): True. Oracle Data Integrator (ODI) Web Edition, which integrates with Data Transforms, retains the full transformation capabilities of ODI Classic, adapted for a web-based interface.
The incorrect statements are:
Data Transforms provides access to Oracle Data Integrator (ODI) Web Edition (A): False. Data Transforms is a distinct tool within ADB; while it leverages ODI under the hood, it does not directly provide access to ODI Web Edition as a standalone product.
Workflows for Data Transforms are only available on the ODI Web Edition (C): False. Workflows are part of Data Transforms itself, not exclusive to ODI Web Edition.
These features enhance data integration in ADB.
NEW QUESTION # 26
You need to set up a notification for a scheduled shutdown of an Autonomous Database instance. What should you do?
- A. Create an Oracle Cloud Infrastructure Alarm for Shutdown metric
- B. Create a notification alert using DBMS_SNMP package
- C. Add a 'BEFORE SHUTDOWN ON DATABASE' trigger within the database
- D. Create a rule for the Oracle Cloud Infrastructure Event for 'Autonomous Database STOP END'
Answer: D
Explanation:
Setting up notifications for scheduled shutdowns leverages OCI Events:
Correct Answer (A): Creating a rule for the 'Autonomous Database STOP END' event in OCI Events triggers a notification (e.g., email via Notification Service) when the shutdown completes. This is the recommended method for tracking lifecycle events in Autonomous Database.
Incorrect Options:
B: There is no specific "Shutdown" metric in OCI Metrics; alarms monitor performance metrics, not lifecycle events like shutdowns.
C: Database triggers like BEFORE SHUTDOWN are not supported in Autonomous Database due to its managed nature, and they wouldn't integrate with OCI notifications.
D: DBMS_SNMP is for network management, not event notifications in Autonomous Database.
This approach ensures reliable, external notification of shutdown events.
