NEW QUESTION # 75
Which index type is designed to index catalog information?
- A. CONTEXT
- B. CONSTRAINS
- C. CTXRULE
- D. CTXCAT
Answer: D
Explanation:
Oracle provides specialized index types for different data indexing needs. The correct answer is:
CTXCAT (B): The CTXCAT index type is specifically designed for indexing catalog information, such as product catalogs or structured data with short text fields. It supports fast queries on structured data combined with text search, making it ideal for applications like e-commerce catalogs.
The incorrect options are:
CONTEXT (A): The CONTEXT index is used for full-text search on large unstructured text data (e.g., documents), not specifically for catalog information.
CTXRULE (C): The CTXRULE index is designed for rule-based classification of text, not for catalog indexing.
CONSTRAINS (D): This appears to be a typo (likely meant "CONSTRAINTS"), but constraints are not index types; they enforce data integrity rules, not indexing.
CTXCAT enhances performance for catalog-style queries, distinguishing it from other text index types.
NEW QUESTION # 76
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. RTO is 2 minutes for an automatic failover
- C. RTO and RPO are 0 minutes for manual failovers
- D. RPO is 0 minutes for an automatic failover
- E. RTO and RPO are adjustable through the OCI console
Answer: B,D
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 # 77
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 'No Preference'
- B. Change the Automatic Maintenance Schedule to 'Specify a Schedule' but do not select any month, week, or day
- C. You cannot permanently disable scheduled Automatic Maintenance
- D. Change the Automatic Maintenance Schedule to 'None'
Answer: C
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 # 78
What is the correct way to list all files in the default data pump directory?
- A. You cannot list files in the default data pump directory from Autonomous Data Warehouse (ADW)
- B. By executing SELECT * FROM UTL_FILE.LIST('DATA_PUMP_DIR');
- C. Log onto ADW server and issue ls -al on the command line
- D. By executing SELECT * FROM DBMS_CLOUD.LIST_FILES('DATA_PUMP_DIR');
Answer: D
Explanation:
In Oracle Autonomous Database, the DBMS_CLOUD package provides tools to interact with cloud storage and directory operations, including listing files in the default Data Pump directory (DATA_PUMP_DIR).
Correct Answer (A): The statement SELECT * FROM DBMS_CLOUD.LIST_FILES('DATA_PUMP_DIR'); is the officially supported method to list files in the DATA_PUMP_DIR. This function returns a result set with details about files in the specified directory, tailored for the managed environment of Autonomous Database.
Incorrect Options:
B: This is false; you can list files in DATA_PUMP_DIR using DBMS_CLOUD.LIST_FILES, as it is designed for this purpose in ADW.
C: The UTL_FILE package is not recommended for Autonomous Database due to its limitations in a cloud-managed environment. DBMS_CLOUD is the preferred utility for such operations. Additionally, the syntax UTL_FILE.LIST is incorrect; the proper procedure would be UTL_FILE.FGETATTR or similar, but it's still not applicable here.
D: Autonomous Database is a fully managed service, and users do not have direct command-line access to the underlying server. Commands like ls -al are unavailable as there's no shell access.
This approach ensures secure and efficient file management within the constraints of a serverless cloud database.

NEW QUESTION # 80
Which Autonomous Database Service is NOT used to connect to an Autonomous Transaction Processing instance?
- A. MEDIUM
- B. TPURGENT
- C. TPPERFORMANT
- D. LOW
- E. HIGH
Answer: C
Explanation:
Full Detailed In-Depth Explanation:
Autonomous Transaction Processing (ATP) supports specific service names for connectivity:
TPURGENT: High-priority service with 200 concurrent statements per OCPU and parallelism.
MEDIUM: Balanced service for moderate workloads.
HIGH: Optimized for reporting/batch jobs with high parallelism.
LOW: Low-priority service for minimal resource use.
TP: General-purpose transactional service.
TPPERFORMANT is not a recognized service name in ATP documentation, making A the correct answer.
NEW QUESTION # 81
Which two objects are imported when using Data Pump to migrate your Oracle database to Autonomous Database? (Choose two.)
- A. Report
- B. Data
- C. Tablespaces
- D. Schemas
Answer: B,D
Explanation:
Oracle Data Pump is a key tool for migrating databases to Autonomous Database. The two objects imported are:
Data (B): Data Pump imports the actual data from the source database into the target Autonomous Database. This includes rows from tables, LOBs, and other data types stored in the dump file (e.g., .dmp). For example, if you export a table CUSTOMERS with 1 million rows, Data Pump imports all that data into ADB using DBMS_CLOUD.COPY_DATA after uploading the dump to OCI Object Storage. This ensures the content of your database is transferred intact.
Schemas (C): Data Pump imports schema definitions, including tables, views, indexes, triggers, and other objects owned by the schema. For instance, exporting a schema HR with tables like EMPLOYEES and DEPARTMENTS will recreate those objects in ADB, preserving their structure. The impdp utility or DBMS_CLOUD handles schema metadata, though some objects (e.g., indexes) may be recreated automatically by ADB's optimization.
The incorrect options are:
Tablespaces (A): Tablespaces are not imported directly. In Autonomous Database, storage is fully managed, and tablespaces are abstracted away. Data Pump imports data and schemas into ADB's managed tablespaces (e.g., DATA), not user-defined ones from the source. For example, a source tablespace USERS isn't replicated; its data is mapped to ADB's default storage.
Report (D): "Report" is not a database object; it might refer to query outputs or logs, but Data Pump doesn't import such entities. It focuses on database content, not external artifacts.
This process ensures a smooth migration of data and structure to ADB's managed environment.
NEW QUESTION # 82
Which statement is FALSE about setting up compartment quotas?
- A. Compartment quotas cannot be set on the root compartment.
- B. Quotas set on a parent compartment override quotas set on child compartments.
- C. Compartment quotas use policies that allow allocation of resources with a high level of flexibility.
- D. You cannot manage quotas in a compartment unless you belong to a group that has the correct permissions.
Answer: A
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.
NEW QUESTION # 83
You have a requirement to create an Autonomous Transaction Processing database that can support at least 200 concurrent statements per OCPU as well as parallelism. Which service will you need to connect to?
- A. TPURGENT
- B. MEDIUM
- C. TP
- D. LOW
Answer: A
Explanation:
Full Detailed In-Depth Explanation:
Autonomous Transaction Processing (ATP) offers predefined service levels with varying concurrency and parallelism capabilities:
MEDIUM: Supports up to 50 concurrent statements per OCPU, with no parallelism by default. Unsuitable for the requirement.
TPURGENT: Supports up to 200 concurrent statements per OCPU and enables manual parallelism. This meets both requirements (concurrency ≥ 200 and parallelism), making it the correct choice.
LOW: Supports only 25 concurrent statements per OCPU, with no parallelism. Insufficient for the requirement.
TP: Supports 125 concurrent statements per OCPU, with no parallelism by default. Falls short of the 200 concurrency threshold.
TPURGENT is designed for high-concurrency, time-sensitive workloads, providing the necessary resources and flexibility for parallel query execution, aligning perfectly with the specified needs.
NEW QUESTION # 84
Which predefined service connection should you use when running lots of high concurrent queries in an Autonomous Database?
- A. DBNAME_LOW
- B. DBNAME_MEDIUM
- C. DBNAME_HIGH
- D. DBNAME_CONCURRENT
Answer: A
Explanation:
Full Detailed In-Depth Explanation:
Service connections in Autonomous Database:
A . DBNAME_LOW: Optimized for high concurrency with minimal resources per query, ideal for many simultaneous queries.
B . DBNAME_MEDIUM: Balanced concurrency and performance.
C . DBNAME_HIGH: Prioritizes individual query performance, not concurrency.
D . DBNAME_CONCURRENT: Not a valid service name.
NEW QUESTION # 85
Which workload type does the Autonomous Database on dedicated infrastructure service currently support?
- A. Autonomous Transaction Processing only
- B. Hybrid Columnar Compression
- C. Autonomous Data Warehouse only
- D. ATP and ADW
Answer: D
Explanation:
Autonomous Database on dedicated infrastructure supports multiple workload types. The correct answer is:
ATP and ADW (C): Autonomous Database on dedicated infrastructure supports both Autonomous Transaction Processing (ATP) for OLTP workloads (high concurrency, low latency) and Autonomous Data Warehouse (ADW) for analytical workloads (high throughput, complex queries). This dual support allows flexibility within a single dedicated Exadata infrastructure.
The incorrect options are:
Autonomous Transaction Processing only (A): Incorrect, as ADW is also supported.
Hybrid Columnar Compression (B): HCC is a data compression feature, not a workload type; it's used within ADW but doesn't define the workload.
Autonomous Data Warehouse only (D): Incorrect, as ATP is also supported.
This versatility is a key feature of dedicated deployments.
NEW QUESTION # 86
Which two statements are true when running DBMS_CLOUD.COPY_DATA? (Choose two.)
- A. The source file will be automatically removed after the DBMS_CLOUD.COPY_DATA procedure finishes successfully.
- B. The source files can reside in Oracle Object Storage, Amazon S3 Object Storage, or Azure Blob Storage.
- C. A valid credential must be created prior to running the DBMS_CLOUD.COPY_DATA procedure.
- D. The target table will be created in Autonomous Database if it does not already exist.
- E. The source file can be in either Oracle Standard Storage or Oracle Archive Storage bucket in the Object Store.
Answer: B,C
Explanation:
DBMS_CLOUD.COPY_DATA loads data into Autonomous Database:
Correct Answer (B): "The source files can reside in Oracle Object Storage, Amazon S3 Object Storage, or Azure Blob Storage" is true. The procedure supports these cloud storage services with proper credentials.
Correct Answer (E): "A valid credential must be created prior to running the DBMS_CLOUD.COPY_DATA procedure" is true. Credentials (e.g., via DBMS_CLOUD.CREATE_CREDENTIAL) authenticate access to the source storage.
Incorrect Options:
A: Source files are not automatically removed; deletion requires separate action.
C: The target table must exist; COPY_DATA doesn't create it.
D: Archive Storage isn't supported; only Standard Storage is compatible.
This enables flexible data loading from cloud storage.

- C. ODI Web Edition is available only on Oracle Linux.
- D. Data Transforms Card provides access to Oracle Data Integrator (ODI) Web Edition.
Answer: A,B
Explanation:
Oracle Data Integrator (ODI) Web Edition integrates with Autonomous Database:
Correct Answer (B): "ODI Web Edition can be installed from Oracle Cloud Infrastructure (OCI) Marketplace" is true. It's offered as a Marketplace image for easy deployment on OCI compute instances.
Correct Answer (D): "All capabilities of ODI Classic are available with ODI Web Edition" is correct; the web version retains full functionality for data integration tasks.
Incorrect Options:
A: ODI Web Edition is not limited to Oracle Linux; it runs on various platforms supported by OCI.
C: The Data Transforms Card in Database Actions uses a simplified UI, not full ODI Web Edition access.
This enhances data integration flexibility in the cloud.

- B. You can use the Service Console to move Autonomous DB between compartments.
- C. You can use the Service Console to enable or disable auto-scaling of Autonomous DB.
- D. You can use the Service Console to create manual backups of Autonomous Database.
Answer: A
Explanation:
Full Detailed In-Depth Explanation:
The Service Console in Autonomous Database is for database-level management:
A: False. Auto-scaling is managed via OCI console.
B: True. It allows monitoring and terminating runaway SQL statements.
C: False. Compartment moves are OCI console tasks.
D: False. Manual backups are initiated via OCI or SQL*Plus.
NEW QUESTION # 89
Which statement is true when you provision an Autonomous Database using the cloning method?
- A. A clone database source can be from a point-in-time backup that is less than 2 hours old.
- B. There is only one type of cloning option available in Autonomous Database.
- C. You can clone a database in a security zone to create a database that isn't in a security zone.
- D. A clone database source can be a running database instance.
Answer: D
Explanation:
Cloning in Autonomous Database creates a new instance from an existing source:
Correct Answer (A): "A clone database source can be a running database instance" is true. You can clone from a live, running Autonomous Database instance (full clone), capturing its current state, including data and configuration, without needing to stop it.
Incorrect Options:
B: There are multiple cloning types: full clone (from a running instance) and refreshable clone (a read-only copy that syncs with the source), plus cloning from backups.
C: Cloning from a backup requires the backup to be at least 2 hours old for consistency, not less, making this false.
D: Security zone rules prevent cloning a database from a security zone to a non-security zone due to compliance restrictions.
This flexibility supports rapid provisioning from active databases.
NEW QUESTION # 90
DBSRV1 is an Autonomous Database with the display name PRODDB. You plan to take manual backups of this database periodically. What must be the name of the bucket that will be used to store manual backups?
- A. BACKUP_PRODDB
- B. backup_dbsrv1
- C. backup_proddb
- D. BACKUP_DBSRV1
Answer: D
Explanation:
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_<DB_UNIQUE_NAME> (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_<UNIQUE_NAME> 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.
NEW QUESTION # 91
Which are two available options when creating an Autonomous Database? (Choose two.)
- A. APEX Service on Dedicated Infrastructure
- B. Autonomous JSON Database on Shared Infrastructure
- C. APEX Service on Shared Infrastructure
- D. Autonomous JSON Database on Dedicated Infrastructure
Answer: A,B
Explanation:
Creating an Autonomous Database offers specific deployment options. The two correct ones are:
APEX Service on Dedicated Infrastructure (A): This option provisions an Autonomous Database on dedicated Exadata infrastructure with Oracle Application Express (APEX) pre-installed and optimized. It's ideal for APEX-based apps (e.g., custom web forms) requiring isolated resources. In the OCI console, you select "Dedicated Infrastructure" and "APEX Service" as the workload type, specifying OCPUs and storage. For example, a company might deploy an APEX app for internal reporting on a dedicated ACD, ensuring performance isolation from other tenants.
Autonomous JSON Database on Shared Infrastructure (C): This creates a schema-less, JSON-centric ADB on shared infrastructure, optimized for document storage (e.g., { "order_id": 123, "items": [...] }). It's provisioned via the OCI console under "Shared Infrastructure," selecting "JSON Database" as the workload type. For instance, a mobile app might use it to store user data, leveraging SQL/JSON queries like SELECT JSON_VALUE(doc, '$.order_id'). It's cost-effective and fully managed, sharing Exadata resources.
The incorrect options are:
APEX Service on Shared Infrastructure (B): There's no distinct "APEX Service" workload type on shared infrastructure. APEX is available within ATP or ADW on shared infra, but it's not a standalone option-you'd provision ATP and enable APEX manually, not as a dedicated "APEX Service." Autonomous JSON Database on Dedicated Infrastructure (D): JSON Database is only offered on shared infrastructure, not dedicated. Dedicated options include ATP, ADW, and APEX Service, but JSON Database leverages shared resources for simplicity and cost.
These options cater to specific app development (APEX) and NoSQL (JSON) needs.
