NEW QUESTION # 68
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. A clone database source can be a running database instance.
- D. You can clone a database in a security zone to create a database that isn't in a security zone.
Answer: C
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 # 69
For fleet admins to access dedicated Exadata infrastructure, which policy should be assigned?
- A. Allow group adb-admins to manage autonomous-database in tenancy where target.workloadType='DW'
- B. Allow group adb-admins to manage autonomous-database in tenancy where target.workloadType='OLTP'
- C. Allow group adb-admins to manage autonomous-database-family in tenancy
- D. Allow group adb-admins to manage autonomous-database in tenancy
Answer: C
Explanation:
Fleet administrators managing dedicated Exadata infrastructure in Oracle Autonomous Database require broad permissions across all Autonomous Database resources, including those on dedicated infrastructure.
Correct Answer (B): The policy Allow group adb-admins to manage autonomous-database-family in tenancy grants comprehensive management rights over the entire Autonomous Database family, including dedicated Exadata infrastructure. The autonomous-database-family resource type encompasses all Autonomous Database resources (shared and dedicated) within the tenancy, making it suitable for fleet admins.
Incorrect Options:
A: Limits permissions to databases with the OLTP workload type (Autonomous Transaction Processing), excluding Data Warehouse (DW) or other types on dedicated infrastructure.
C: Restricts access to DW workload types only, omitting OLTP and other configurations.
D: Grants permissions only to autonomous-database resources, which may not fully cover dedicated infrastructure components like Autonomous Container Databases or Exadata Infrastructure.
This policy ensures fleet admins have the necessary scope to manage all aspects of dedicated deployments.
NEW QUESTION # 70
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 use policies that allow allocation of resources with a high level of flexibility.
- C. Quotas set on a parent compartment override quotas set on child compartments.
- D. Compartment quotas cannot be set on the root compartment.
Answer: D
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 # 71
For someone that is not a service administrator to use SQL Developer Web, what package would you need to use to give them access?
- A. ORDS_ADMIN.GRANT_SCHEMA
- B. ORDS_ADMIN.ENABLE_SCHEMA
- C. SQLDEV_ADMIN.GRANT_SCHEMA
- D. ORDS_PRIV.ENABLE_SCHEMA
Answer: B
Explanation:
SQL Developer Web in Autonomous Database relies on Oracle REST Data Services (ORDS) for access. The correct package is:
ORDS_ADMIN.ENABLE_SCHEMA (B): To allow a non-admin user (e.g., ANALYST1) to use SQL Developer Web, the ADMIN user executes ORDS_ADMIN.ENABLE_SCHEMA to enable the schema for ORDS access. This procedure activates the schema for RESTful services, granting privileges like CONNECT and SELECT implicitly for web-based SQL execution. Example:
BEGIN
ORDS_ADMIN.ENABLE_SCHEMA(p_schema => 'ANALYST1');
END;
After this, the user accesses SQL Developer Web via a URL (e.g., https://<adb-host>/ords/analyst1/_sdw), logging in with their database credentials. This is necessary because SQL Developer Web runs on ORDS, and only enabled schemas can interact with it. For instance, an analyst might query SELECT * FROM sales in the web interface post-enablement, without needing full admin rights.
The incorrect options are:
ORDS_ADMIN.GRANT_SCHEMA (A): No such procedure exists in ORDS_ADMIN. Granting is handled via database roles/privileges (e.g., GRANT CONNECT), not a specific ORDS grant function.
ORDS_PRIV.ENABLE_SCHEMA (C): There's no ORDS_PRIV package; this might confuse with ORDS_ADMIN. The correct package is ORDS_ADMIN for schema enablement.
SQLDEV_ADMIN.GRANT_SCHEMA (D): No SQLDEV_ADMIN package exists. SQL Developer Web access is managed through ORDS, not a separate SQL Developer-specific package.
ORDS_ADMIN.ENABLE_SCHEMA is the standard, secure way to enable non-admin access to this tool in ADB.
NEW QUESTION # 72
Which three Oracle Cloud Infrastructure (OCI) resources do you need to configure before provisioning your Autonomous Database with a private endpoint? (Choose three.)
- A. Network Security Group
- B. VCN
- C. Subnet
- D. Security List
- E. Route Table
Answer: A,B,C
Explanation:
Provisioning an Autonomous Database with a private endpoint requires:
Correct Answer (A): Network Security Group (NSG) defines traffic rules for the private endpoint, restricting access to specific sources.
Correct Answer (B): VCN (Virtual Cloud Network) provides the network foundation, hosting the subnet and endpoint.
Correct Answer (E): Subnet (private) contains the database's private endpoint, isolating it from public access.
Incorrect Options:
C: Security Lists apply to subnets but are optional with NSGs, which are preferred for finer control.
D: Route Table is needed for connectivity (e.g., to a NAT Gateway), but not strictly required for the private endpoint itself.
These ensure secure, private access.
NEW QUESTION # 73
Which three security features are available in Oracle Autonomous Database Shared Infrastructure? (Choose three.)
- A. Audit Vault
- B. Transparent Data Encryption
- C. Database Vault
- D. Customer Managed Keys
- E. Data Redaction
Answer: B,C,D
Explanation:
Oracle Autonomous Database Shared Infrastructure offers built-in security features to protect data and ensure compliance. The three correct features are:
Customer Managed Keys (A): This feature allows customers to use their own encryption keys for Transparent Data Encryption (TDE), stored in Oracle Key Vault or OCI Vault. It gives control over key management, enhancing security by ensuring only the customer can decrypt data. For example, a company might generate a key in OCI Vault, link it to their ADB, and rotate it periodically, all managed outside Oracle's default keys.
Database Vault (D): Oracle Database Vault enforces fine-grained access controls, preventing unauthorized access to sensitive data even by privileged users (e.g., DBAs). In ADB shared infrastructure, it's available to restrict operations like SELECT on specific schemas, adding a layer of protection against internal threats. For instance, it could block an admin from viewing customer PII unless explicitly permitted.
Transparent Data Encryption (E): TDE is enabled by default in Autonomous Database, encrypting data at rest (e.g., in tablespaces, backups, and logs) using AES-256. This ensures that if physical storage is compromised, the data remains unreadable without the encryption key. Customers can opt for customer-managed keys (A) or use Oracle-managed keys, but TDE itself is always active.
The incorrect options are:
Audit Vault (B): Oracle Audit Vault is a separate product for centralized audit log management, not a built-in feature of ADB shared infrastructure. While ADB performs auditing, it doesn't include Audit Vault's advanced capabilities natively.
Data Redaction (C): Data Redaction (masking sensitive data in query results) is available in on-premises Oracle Database Enterprise Edition but is not supported in Autonomous Database shared infrastructure. ADB's managed nature limits such custom configurations, relying instead on TDE and Database Vault for security.
These features collectively ensure robust security with minimal customer effort in a shared environment.
NEW QUESTION # 74
Where can a user's public SSH key be added on the Oracle Cloud Infrastructure Console in order to execute API calls?
- A. SSH keys are not required in Oracle Cloud Infrastructure
- B. SSH keys cannot be added from console. They have to be added using REST APIs only
- C. Navigate to Identity, select Users panel on the console and select "Add Public Key"
- D. On the Autonomous Database Console
Answer: C
Explanation:
SSH keys in OCI are used for secure access, but their role in API calls needs clarification. The correct answer is:
Navigate to Identity, select Users panel on the console and select "Add Public Key" (D): This is the correct process, but with a caveat-it's about API authentication, not SSH for API calls per se. In OCI, API calls are authenticated using API keys (RSA key pairs), not SSH keys directly. To enable API access for a user, you generate a public/private key pair (e.g., using openssl), then add the public key in the OCI console:
Go to "Identity & Security" > "Users."
Select the user (e.g., john.doe).
Under "API Keys," click "Add API Key."
Upload the public key (e.g., ~/.oci/oci_api_key_public.pem).
This associates the key with the user, allowing API calls (e.g., oci db autonomous-database list) authenticated via the private key and config file (e.g., ~/.oci/config). The question's phrasing ("SSH key") likely misuses terminology, intending "API key," as SSH keys are for compute instance access, not APIs. For example, a user might add a key to call the ADB API, securing requests with a signature.
The incorrect options are:
On the Autonomous Database Console (A): The ADB console manages database-specific settings (e.g., wallets), not user API keys, which are handled at the tenancy level under Identity.
SSH keys are not required in Oracle Cloud Infrastructure (B): False in general-SSH keys are needed for compute instances-but misleading here, as API calls use API keys, not SSH keys. Authentication (e.g., via tokens or keys) is required for APIs.
SSH keys cannot be added from console. They have to be added using REST APIs only (C): False. The console supports adding API keys under the Users panel; REST APIs (e.g., CreateApiKey) are an alternative, not the only method.
The correct path reflects OCI's user management for API access, despite the SSH terminology confusion.
NEW QUESTION # 75
When cloning from a backup, what is the earliest timestamp of the backup allowed in Autonomous Database?
- A. 1 hour
- B. 24 hours
- C. 2 hours
- D. 30 minutes
Answer: C
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
Which two license types does the customer need to benefit from BYOL when leveraging on-premise Enterprise Database licenses in Oracle Autonomous Database?
- A. Active Data Guard
- B. Real Application Clusters (RAC), but only when scaling beyond 16 OCPUs
- C. Exadata
- D. Multitenant
- E. Transparent Data Encryption (TDE)
Answer: B,D
Explanation:
Full Detailed In-Depth Explanation:
Bring Your Own License (BYOL) allows using existing on-premises Oracle licenses in the cloud:
A: False. Exadata is included in Autonomous Database; no separate license is needed.
B: False. Active Data Guard is an optional feature, not required for BYOL.
C: True. RAC is needed for BYOL when scaling beyond 16 OCPUs, as Autonomous Database uses RAC for high availability in larger deployments.
D: True. Multitenant is mandatory, as Autonomous Database uses a multitenant architecture (CDB/PDB).
E: False. TDE is included by default, not a BYOL requirement.
NEW QUESTION # 77
Which two objects are imported when using Data Pump to migrate your Oracle database to Autonomous Database? (Choose two.)
- A. Tablespaces
- B. Report
- C. Schemas
- D. Data
Answer: C,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 # 78
Where are the customer-managed encryption keys stored for Autonomous Database on Dedicated Infrastructure?
- A. Inside the Autonomous Database wallet
- B. In a separate key vault external to the Exadata infrastructure
- C. On the Exadata infrastructure where the Autonomous Database Dedicated is hosted
- D. Inside the backup of the container database
Answer: B
Explanation:
Customer-managed encryption keys enhance security control:
Correct Answer (A): "In a separate key vault external to the Exadata infrastructure" refers to OCI Vault (Key Management Service), where keys are securely stored and managed outside the database infrastructure.
Incorrect Options:
B: The wallet secures connections, not encryption keys.
C: Storing keys on Exadata compromises separation of duties.
D: Backups don't store keys; they're encrypted by keys from the vault.
This separation ensures robust key management.
NEW QUESTION # 79
Which is an Autonomous Database critical event?
- A. Admin Password Warning
- B. New Maintenance Schedule
- C. Schedule Maintenance Warning
- D. Maintenance Begin
- E. Database Connection
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 # 80
Which two statements are true about Data Insights?
- A. Data Insights is available with on-premises deployments of Oracle Database.
- B. You can search for Data Insights against a base table or business model.
- C. You can retrieve previously executed Data Insights searches.
- D. Data Insights is an additional priced option.
Answer: B,C
Explanation:
Full Detailed In-Depth Explanation:
A: True. Data Insights works with tables and business models in ADW.
B: False. Exclusive to Autonomous Database, not on-premises.
C: True. Search history is retrievable.
D: False. Included in ADW, not separately priced.
NEW QUESTION # 81
Which Autonomous Database Cloud Service ignores hints in SQL statements by default?
- A. Neither service ignores hints by default
- B. Autonomous Transaction Processing
- C. Both services ignore hints by default
- D. Autonomous Data Warehouse
Answer: D
Explanation:
Full Detailed In-Depth Explanation:
Oracle Autonomous Database offers two primary services: Autonomous Data Warehouse (ADW) and Autonomous Transaction Processing (ATP), each optimized for different workloads. SQL hints are directives embedded in SQL statements to influence the optimizer's execution plan. However, their handling differs between the services:
Autonomous Data Warehouse (ADW): ADW is designed for analytical workloads and data warehousing, where query performance is critical. To ensure optimal execution, ADW's optimizer relies heavily on its own statistics and algorithms, ignoring SQL hints by default. This behavior prevents user-provided hints from overriding the automated optimization strategies tailored for complex analytical queries.
Autonomous Transaction Processing (ATP): ATP targets transactional workloads (OLTP) and provides more flexibility. It does not ignore hints by default, allowing developers and DBAs to use hints to fine-tune query execution plans for specific transactional needs.
Thus, only ADW ignores hints by default, making option C the correct answer. Options A and B are incorrect because ATP does not share ADW's default behavior, and option D incorrectly identifies ATP as the service that ignores hints.
NEW QUESTION # 82
Which two cloud services allow you to import Data Pump files to an Autonomous Database on Dedicated Infrastructure? (Choose two.)
- A. Google Cloud Storage
- B. Azure Blob Storage
- C. Oracle Cloud Infrastructure Object Storage Classic
- D. Oracle Cloud Infrastructure Object Storage
- E. Amazon S3
Answer: C,D
Explanation:
Importing Data Pump files into an Autonomous Database on Dedicated Infrastructure requires compatibility with Oracle-managed cloud storage services:
Correct Answer (C): Oracle Cloud Infrastructure Object Storage Classic is an older OCI storage service that supports Data Pump imports. Users can upload dump files to a Classic bucket and use the DBMS_CLOUD package to import them into the database.
Correct Answer (E): Oracle Cloud Infrastructure Object Storage (the modern OCI Object Storage) is fully supported for Data Pump imports, offering scalability and integration with Autonomous Database via DBMS_CLOUD.
Incorrect Options:
A: Amazon S3 is not natively supported for direct Data Pump imports into Autonomous Database on Dedicated Infrastructure without additional integration steps.
B: Azure Blob Storage is similarly unsupported natively; Autonomous Database prioritizes OCI storage.
D: Google Cloud Storage is not integrated for this purpose.
These OCI services ensure seamless and secure data migration.
NEW QUESTION # 83
Which command can you use to create an Autonomous Database?
- A. POST /20160918/autonomousDatabases
- B. POST /20160918/createADB
- C. POST /20160918/createDatabases
- D. POST /20160918/createautonomousDatabases
Answer: A
Explanation:
Creating an Autonomous Database (ADB) via OCI's REST API involves a specific endpoint. The correct command is:
POST /20160918/autonomousDatabases (D): This is the official REST API endpoint to create an ADB instance. The POST request to /20160918/autonomousDatabases (versioned at API 20160918) submits a JSON payload defining the database (e.g., compartment, name, workload type). Example:
curl -X POST "https://database.us-ashburn-1.oraclecloud.com/20160918/autonomousDatabases" \
-H "Authorization: Bearer <token>" \
-H "Content-Type: application/json" \
-d '{
"compartmentId": "ocid1.compartment.oc1..example",
"dbName": "MYADB",
"cpuCoreCount": 1,
"dataStorageSizeInTBs": 1,
"dbWorkload": "OLTP",
"adminPassword": "Secure#123"
}'
This creates an ATP instance named MYADB with 1 OCPU and 1 TB storage. The response includes an OCID (e.g., ocid1.autonomousdatabase.oc1..example), and provisioning starts asynchronously, visible in the OCI console as "PROVISIONING." The endpoint's plural form (autonomousDatabases) reflects the resource collection, consistent with OCI API conventions.
The incorrect options are:
POST /20160918/createADB (A): No such endpoint exists. OCI APIs use resource-based paths (e.g., /autonomousDatabases), not action-specific ones like createADB.
POST /20160918/createautonomousDatabases (B): Incorrect syntax-APIs don't prepend "create" to resource paths, and "autonomousDatabases" is lowercase here, matching the real endpoint.
POST /20160918/createDatabases (C): Too generic; it doesn't specify "autonomous" databases, and no such endpoint exists for ADB creation.
This REST command is a programmatic alternative to console-based provisioning, ideal for automation.
NEW QUESTION # 84
Which three of the following data sources are available when using the Data Load page on Database Actions?
- A. Backup files in block storage
- B. REST endpoints
- C. Files in AWS S3 Storage
- D. Local Files
- E. Files in Oracle Cloud Storage
Answer: C,D,E
Explanation:
Full Detailed In-Depth Explanation:
The Data Load page in Database Actions supports loading data from:
A . Local Files: True. Users can upload files from their local device.
B . Files in Oracle Cloud Storage: True. OCI Object Storage is a supported source.
C . REST endpoints: False. REST is not a direct data source for Data Load; it's used for programmatic access.
D . Files in AWS S3 Storage: True. Integration with AWS S3 is supported for cloud flexibility.
E . Backup files in block storage: False. Block storage backups are not accessible via Data Load.
A, B, and D are the correct options per Oracle's documentation.
NEW QUESTION # 85
Which two actions can be performed when an Autonomous Database is stopped? (Choose two.)
- A. Update License type
- B. Start
- C. Update Network Access
- D. Change administrator password
Answer: A,B
Explanation:
When an Autonomous Database is stopped, limited actions are available:
Correct Answer (B): Start is possible to bring the database back online via the OCI Console or API.
Correct Answer (C): Update License type (e.g., from License Included to Bring Your Own License) can be performed while stopped, as it's a configuration change not requiring database activity.
Incorrect Options:
A: Changing the admin password requires the database to be running for security validation.
D: Updating network access (e.g., ACLs) requires an active instance to apply changes.
These options reflect the stopped state's constraints.
NEW QUESTION # 86
Which two infrastructure types support deployment of Oracle Autonomous Database? (Choose two.)
- A. Dedicated Exadata Infrastructure
- B. Shared Exadata Infrastructure
- C. Oracle Bare Metal Servers
- D. Virtual Machines on Oracle Cloud Infrastructure
Answer: A,B
Explanation:
Oracle Autonomous Database is designed to run on specific infrastructure optimized for its managed capabilities:
Correct Answer (B): Dedicated Exadata Infrastructure provides a fully dedicated Exadata system for a single tenant, offering maximum isolation, performance, and customization (e.g., maintenance scheduling).
Correct Answer (D): Shared Exadata Infrastructure allows multiple Autonomous Database instances to share Exadata resources, providing a cost-effective option for smaller workloads while retaining automation benefits.
Incorrect Options:
A: Virtual Machines (VMs) on OCI are not a supported deployment platform for Autonomous Database. It requires Exadata hardware for its self-managing features, unlike traditional OCI VMs used for manual database setups.
C: Oracle Bare Metal Servers are not used for Autonomous Database; they lack the specialized Exadata architecture needed for its autonomous operations.
These infrastructure types ensure high performance and scalability tailored to Autonomous Database's requirements.
