Which statement is false about Autonomous Database Oracle Client Credentials (Wallets)?
- A. The Oracle Client Credential file is downloaded as a ZIP file
- B. In addition to the Oracle Client Credential Wallet, a user must have a username and password in order to connect to the Autonomous Database
- C. You must have an Oracle Client Credential wallet in order to connect to the Autonomous Database
- D. The Wallet for the Autonomous Database is the same as the TDE wallet
Answer: D
Explanation:
Oracle Client Credentials (wallets) are essential for secure connections to the Autonomous Database. The false statement is:
The Wallet for the Autonomous Database is the same as the TDE wallet (A): This is incorrect. The Oracle Client Credential wallet (used for client authentication and connection security) is distinct from the Transparent Data Encryption (TDE) wallet (used to encrypt data at rest within the database). The client wallet contains certificates and keys for mutual TLS (mTLS) authentication, while the TDE wallet manages encryption keys for data security. They serve different purposes and are not the same.
The correct statements are:
You must have an Oracle Client Credential wallet in order to connect to the Autonomous Database (B): True. The wallet is required for mTLS, which is the default authentication method for Autonomous Databases, ensuring secure connections.
In addition to the Oracle Client Credential Wallet, a user must have a username and password in order to connect to the Autonomous Database (C): True. Alongside the wallet, a database username and password are needed for full authentication (mTLS + user credentials).
The Oracle Client Credential file is downloaded as a ZIP file (D): True. When downloaded from the Oracle Cloud Infrastructure (OCI) console, the wallet is provided as a ZIP file containing configuration files like tnsnames.ora and certificates.
This distinction is critical for understanding security mechanisms in Autonomous Database.
NEW QUESTION # 60
Which is NOT needed to manage Oracle Autonomous Database with REST APIs?
- A. Database ADMIN password
- B. Tenancy's OCID
- C. User's OCID
- D. Fingerprint of the public key
Answer: A
Explanation:
Managing Autonomous Database via REST APIs relies on OCI authentication:
Correct Answer (D): “Database ADMIN password” is not needed. REST API access uses OCI IAM credentials, not database-level credentials like the ADMIN password.
Required Items:
A: User’s OCID identifies the API caller.
B: Tenancy’s OCID specifies the cloud environment.
C: Fingerprint of the public key authenticates API requests with a private-public key pair.
This ensures secure, external management without exposing database credentials.
NEW QUESTION # 61
Which management operation is correct about Autonomous Databases on Shared Exadata Infrastructure?
- A. You can perform a "rolling restart" on all the Autonomous Databases. During a rolling restart, each node on the Autonomous Database is restarted separately while the remaining nodes continue to be available
- B. You can skip a scheduled maintenance run. For Autonomous Database on Shared Exadata Infrastructure, you can skip maintenance runs for up to two consecutive quarters if needed
- C. You can choose to use Release Update or Release Update Revision updates for your Autonomous Databases on Shared Infrastructure
- D. You cannot configure the scheduling for your Autonomous Databases on Shared Exadata Infrastructure
Answer: D
Explanation:
Management operations for Autonomous Databases on Shared Exadata Infrastructure are limited due to its fully managed nature. The correct statement is:
You cannot configure the scheduling for your Autonomous Databases on Shared Exadata Infrastructure (C): In shared infrastructure, Oracle fully controls maintenance scheduling (e.g., patching, upgrades). Unlike dedicated infrastructure, where users can set maintenance windows, shared ADB users cannot adjust timing. Oracle notifies users of upcoming maintenance (e.g., via email or console), typically in a 7-day window, but the exact schedule is Oracle-driven to optimize the shared Exadata platform. For example, a quarterly patch might occur on a Tuesday at 2 AM UTC, and users must adapt, not reschedule.
The incorrect options are:
You can skip a scheduled maintenance run... (A): False. Shared infrastructure does not allow skipping maintenance runs, even for two quarters. This flexibility exists only in dedicated infrastructure, where users have more control (e.g., skipping up to two consecutive updates). In shared mode, Oracle enforces updates for security and stability across all tenants.
You can perform a "rolling restart"... (B): False. Rolling restarts (restarting nodes sequentially for availability) are not user-initiated in ADB shared infrastructure. Restarts, if needed, are managed by Oracle during maintenance, and users cannot control the process or ensure node-by-node availability.
You can choose to use Release Update or Release Update Revision updates... (D): False. In shared infrastructure, Oracle applies Release Updates (RUs) uniformly across all databases; users cannot choose between RU or Release Update Revisions (RURs), a feature reserved for dedicated deployments.
This reflects the trade-off of shared infrastructure: lower cost and management effort for less control.
NEW QUESTION # 62
Which is an Autonomous Database critical event?
- A. Admin Password Warning
- B. Database Connection
- C. Maintenance Begin
- D. New Maintenance Schedule
- E. Schedule Maintenance Warning
Answer: A
Explanation:
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.
NEW QUESTION # 63
Which statement is NOT correct when the Autonomous Database is stopped?
- A. In-flight transactions and queries are stopped.
- B. User with DWROLE can still access the database.
- C. Tools are no longer able to connect to a stopped instance.
- D. CPU billing is halted.
Answer: B
Explanation:
When an Autonomous Database is stopped, its operational state changes significantly:
Correct Answer (C): “User with DWROLE can still access the database” is not correct. When the database is stopped, all access is disabled, including for users with roles like DWROLE (a predefined role for Data Warehouse tasks). The database is offline, and no connections or operations are possible until it is restarted.
True Statements:
A: Tools (e.g., SQL Developer, JDBC clients) cannot connect to a stopped instance because the database services are unavailable.
B: In-flight transactions and queries are terminated upon stopping, with any uncommitted changes rolled back to maintain data consistency.
D: CPU billing ceases when the database is stopped, though storage billing continues, reflecting Oracle’s pay-per-use model for compute resources.
This behavior ensures resource conservation and cost control while maintaining data integrity.

- D. Analytic View Transparency View
- E. Analytic View Base Table Query Transformation
Answer: B,D,E
Explanation:
When creating a business model in Autonomous Database (e.g., via Data Modeler), advanced options enhance analytical capabilities:
Correct Answer (A): Autonomous Aggregate Cache uses dimensional metadata to manage caching, improving query performance.
Correct Answer (B): Analytic View Transparency View exposes analytic views as standard views for compatibility with existing tools.
Correct Answer (C): Analytic View Base Table Query Transformation enables seamless integration of analytic views into existing reports.
Incorrect Options:
D: “Display private tables” is not a recognized advanced option in this context.
E: “Business Object Security Feature” is unrelated to Autonomous Database business modeling.
These options optimize analytical workloads.

- A. The marketplace OCI image does not support connecting to an Autonomous Database on Shared Infrastructure.
- B. A Private Endpoint is required to connect to the Autonomous Database on Shared Exadata infrastructure.
- C. The marketplace OCI image can be used with an Always Free Autonomous Database account.
- D. The Autonomous Database must belong to a Network Security Group (NSG).
Answer: C
Explanation:
Full Detailed In-Depth Explanation:
Connecting a marketplace OCI image (e.g., a pre-configured VM) to an Autonomous Database on Shared Infrastructure involves network and compatibility considerations. Let’s analyze each option:
A . The Autonomous Database must belong to a Network Security Group (NSG): False. NSGs enhance security but are optional. Connectivity can be achieved without them using security lists or other rules.
B . The marketplace OCI image can be used with an Always Free Autonomous Database account: True. The Always Free tier supports connectivity from OCI marketplace images, provided network configurations (e.g., VCN, subnet) allow it. This makes B the correct answer.
C . A Private Endpoint is required to connect to the Autonomous Database on Shared Exadata infrastructure: False. While private endpoints enhance security, public endpoints are also supported for shared infrastructure, making this optional.
D . The marketplace OCI image does not support connecting to an Autonomous Database on Shared Infrastructure: False. Marketplace images are designed to integrate with OCI services, including Autonomous Databases on shared infrastructure.
Option B stands out as it aligns with Oracle’s support for Always Free tiers, offering flexibility for users to leverage marketplace tools without additional cost.
NEW QUESTION # 66
Which two options are available for restoring an Autonomous Database? (Choose two.)
- A. Specifying the archived custom image.
- B. Selecting the snapshot of the backup.
- C. Selecting the backup from which restore needs to be done.
- D. Specifying the point in time (timestamp) to restore.
Answer: C,D
Explanation:
Restoring an Autonomous Database involves specific recovery options:
Correct Answer (A): “Selecting the backup from which restore needs to be done” allows you to choose a specific automatic backup (listed by timestamp) in the OCI Console to restore the database to that state.
Correct Answer (D): “Specifying the point in time (timestamp) to restore” enables Point-in-Time Recovery (PITR), restoring to any moment within the backup retention period (default 60 days), even between backups.
Incorrect Options:
B: There’s no “snapshot of the backup” option; backups are managed as full/incremental sets, not user-selectable snapshots.
C: “Archived custom image” is not a feature of Autonomous Database restore; it applies to other OCI services like Compute.
These options provide flexibility for recovery scenarios.
NEW QUESTION # 67
Which three methods can be used to migrate your existing Oracle database to Autonomous Database? (Choose three.)
- A. Using Data Pump
- B. Using Oracle Zero Downtime Migration (ZDM)
- C. Using Recovery Manager (RMAN)
- D. Using SFTP to copy CSV files into an Autonomous Database
- E. Using GoldenGate
Answer: A,B,E
Explanation:
Migrating to Autonomous Database requires robust tools:
Correct Answer (B): Oracle Zero Downtime Migration (ZDM) minimizes downtime by synchronizing data and schema changes while the source remains online, ideal for critical systems.
Correct Answer (C): GoldenGate provides real-time replication, enabling near-zero downtime migration by continuously syncing data to Autonomous Database.
Correct Answer (D): Data Pump exports data and schema to dump files, which are then imported into Autonomous Database, suitable for offline migrations.
Incorrect Options:
A: SFTP with CSV files is not a comprehensive migration method; it lacks schema migration and automation for complex databases.
E: RMAN is for backup/restore, not optimized for full migrations to Autonomous Database’s managed environment.
These methods cater to different migration needs (online vs. offline).
NEW QUESTION # 68
Which three are use cases for Graph Studio? (Choose three.)
- A. Facial recognition
- B. 3-D modelling
- C. Clustering
- D. Pattern matching
- E. Churn analysis
Answer: C,D,E
Explanation:
Graph Studio in Autonomous Database supports graph-based analysis:
Correct Answer (C): Pattern matching identifies relationships (e.g., fraud rings) using graph queries like PGQL.
Correct Answer (D): Clustering groups related nodes (e.g., communities) using graph algorithms.
Correct Answer (B): Churn analysis leverages graph relationships to predict customer loss (e.g., via influence networks), though less emphasized than C and D, it’s a valid use case.
Incorrect Options:
A: Facial recognition is image-based, not graph-based.
E: 3-D modelling is a misinterpretation; it’s not a primary graph use case.
These align with Graph Studio’s strengths in relationship analysis.
NEW QUESTION # 69
Which statement is FALSE regarding provisioning an Autonomous Database and configuring private endpoints with security rules to allow incoming and outgoing traffic to and from the Autonomous Database instance?
- A. The source is set to the address range you want to allow to connect to your database
- B. The IP Protocol is set to TCP
- C. A stateless ingress rule is created to allow connections from the source to the Autonomous Database instance
- D. The destination port range is set to 1522
Answer: C
Explanation:
Configuring private endpoints for Autonomous Database involves network security rules. The false statement is:
A stateless ingress rule is created to allow connections from the source to the Autonomous Database instance (C): This is incorrect. For Autonomous Database private endpoints, security rules (e.g., in Security Lists or NSGs) must be stateful, not stateless. Stateful rules track connection states (e.g., allowing return traffic automatically), which is necessary for Oracle Net Services (SQL*Net) communication over TCP. A stateless rule requires explicit ingress and egress rules for both directions, complicating setup and risking connectivity issues. For example, a stateful ingress rule from a client subnet (e.g., 10.0.1.0/24) to the ADB subnet ensures bidirectional traffic works seamlessly without additional egress rules.
The true statements are:
The IP Protocol is set to TCP (A): Autonomous Database uses TCP for database connections, aligning with Oracle Net Services standards.
The destination port range is set to 1522 (B): Port 1522 is the default for secure TLS connections to Autonomous Database, as specified in the client wallet’s tnsnames.ora.
The source is set to the address range you want to allow to connect to your database (D): The security rule defines the source CIDR block (e.g., 10.0.0.0/16) of allowed clients, restricting access to specific subnets or VCNs.
Stateful rules simplify and secure private endpoint configurations.
NEW QUESTION # 70
Which three tools can be used to monitor the usage and activities of Autonomous Database on Dedicated Infrastructure? (Choose three.)
- A. Logs

Answer: B,C,D
Explanation:
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.
NEW QUESTION # 71

- C. ALTER SYSTEM SET APPLICATION_CONTINUITY=TRUE
- D. ALTER DATABASE SET APPLICATION_CONTINUITY=TRUE
Answer: B
Explanation:
Application Continuity ensures seamless failover for applications:
Correct Answer (B): EXEC DBMS_CLOUD_ADMIN.ENABLE_APP_CONT('<service_name>'); 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.
NEW QUESTION # 72
Which three operations are available for a quarterly maintenance update on Autonomous Container Database? (Choose three.)
- A. Reschedule and patch immediately
- B. Patch immediately
- C. Skip patching
- D. Apply a partial patch
- E. Reschedule patching
Answer: A,C,E
Explanation:
Oracle Autonomous Container Database (ACD) provides specific options for managing quarterly maintenance updates to ensure minimal disruption and flexibility. The three correct operations available are:
Reschedule and patch immediately (B): This option allows users to adjust the maintenance window to a more convenient time and apply the patch right away within that rescheduled window. It’s useful when the default schedule conflicts with business operations but immediate patching is still desired.
Reschedule patching (C): This option enables users to defer the patching to a later maintenance window that suits their operational needs, providing flexibility without applying the patch immediately.
Skip patching (D): Users can choose to skip a quarterly maintenance update entirely, which is beneficial if the current database version is stable and no immediate updates are required. Oracle allows skipping up to two consecutive quarterly updates for Autonomous Container Databases on dedicated infrastructure.
The incorrect options are:
Patch immediately (A): This is not a standalone option for quarterly updates on ACDs. Patching occurs within scheduled maintenance windows, and immediate patching outside of rescheduling is not supported as a distinct choice.
Apply a partial patch (E): Oracle does not support applying partial patches during quarterly maintenance updates. Updates are delivered as complete bundles to ensure consistency and security.
This aligns with Oracle’s maintenance policies for Autonomous Databases on dedicated infrastructure, where control over scheduling and skipping is provided, but partial patching is not an option.
NEW QUESTION # 73
Who, and in which order, provisions dedicated Exadata Infrastructure resources?
- A. The Database Administrator provisions the Autonomous Exadata Infrastructure. Then, the Fleet Administrator provisions the Autonomous Container DB and then the Autonomous DB
- B. The Fleet Administrator provisions the Autonomous Exadata Infrastructure. Then, the Database Administrator provisions the Autonomous Container DB and then the Autonomous DB
- C. The Fleet Administrator provisions the Autonomous Exadata Infrastructure and then the Autonomous Container DB and then, the Database Administrator provisions the Autonomous DB
- D. The Database Administrator provisions the Autonomous Container DB and the Autonomous D Then, the Fleet Administrator provisions the Autonomous Exadata Infrastructure
Answer: C
Explanation:
Provisioning dedicated Exadata Infrastructure resources for Autonomous Database follows a strict hierarchical order, reflecting roles and dependencies. The correct sequence is:
The Fleet Administrator provisions the Autonomous Exadata Infrastructure and then the Autonomous Container DB and then, the Database Administrator provisions the Autonomous DB (A):
Fleet Administrator provisions Autonomous Exadata Infrastructure (AEI): The Fleet Admin, responsible for infrastructure management, starts by provisioning the AEI via the OCI console (e.g., “Create Autonomous Exadata Infrastructure”). This sets up the physical Exadata hardware, networking (e.g., VCN, subnets), and initial configuration (e.g., 2 racks, 4 nodes). For example, they might specify a compartment and region (e.g., us-ashburn-1), taking 1-2 hours for provisioning.
Fleet Administrator provisions Autonomous Container DB (ACD): Within the AEI, the Fleet Admin creates the ACD (e.g., “Create Autonomous Container Database”), a lightweight container hosting multiple ADBs. They set parameters like version (e.g., 19c) and maintenance windows (e.g., Sundays 02:00 UTC), ensuring the container is ready. This step might take 15-30 minutes.
Database Administrator provisions Autonomous DB (ADB): Finally, the DBA provisions individual ADBs within the ACD (e.g., “Create Autonomous Database”), choosing workload type (ATP/ADW), OCPUs (e.g., 4), and storage (e.g., 1 TB). For instance, they might create an ATP instance named PRODDB for a transactional app, completing setup in 5-10 minutes.
The incorrect options are:
B: The DBA can’t provision the ACD or ADB before the AEI exists, as the infrastructure is foundational. The Fleet Admin must act first.
C: The DBA doesn’t provision AEI—that’s an infrastructure task beyond their scope. The Fleet Admin handles hardware setup.
D: The DBA can’t provision the ACD; that’s a Fleet Admin task within the AEI. Roles are distinct: Fleet Admin for infra, DBA for databases.
This order ensures proper infrastructure setup before database creation, aligning with OCI’s role-based workflow.
NEW QUESTION # 74

Explanation:
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.
NEW QUESTION # 75
When cloning from a backup, what is the earliest timestamp of the backup allowed in Autonomous Database?
- A. 1 hour
- B. 2 hours
- C. 24 hours
- D. 30 minutes
Answer: B
Explanation:
Cloning from a backup in Autonomous Database has a minimum age requirement:
Correct Answer (A): The earliest timestamp allowed is 2 hours after the backup is created. This ensures data consistency by allowing time for any in-flight transactions or writes to stabilize in the backup, preventing incomplete or corrupted clones.
Incorrect Options:
B: 24 hours is the default retention period, not the minimum cloning age.
C, D: 1 hour and 30 minutes are too short; they don’t meet the 2-hour consistency window.
This policy safeguards clone integrity.
NEW QUESTION # 76
