NEW QUESTION # 13
Which workload is particularly suited to Oracle Autonomous JSON Database?
Answer: D
Explanation:
Oracle Autonomous JSON Database is a specialized variant of Autonomous Database. The correct workload is:
Schema-less, document-centric (D): Autonomous JSON Database is designed for applications needing flexible, schema-less data storage and retrieval, particularly JSON documents. It’s a NoSQL-style database optimized for document-centric workloads, such as web or mobile apps storing user profiles, IoT data, or content management systems. For example, a social media app might store user posts as JSON documents { "user": "John", "post": "Hello world" }, allowing dynamic field additions without schema changes. It supports SQL/JSON queries (e.g., SELECT JSON_VALUE(doc, '$.user')), blending relational and NoSQL benefits, and auto-manages indexing for performance.
The incorrect options are:
Data Marts (A): Data marts are structured, analytical stores for aggregated data, better suited to Autonomous Data Warehouse (ADW), which excels at columnar storage and complex queries, not JSON’s flexible format.
Transactions (B): Traditional OLTP transactions (e.g., banking records) are the domain of Autonomous Transaction Processing (ATP), which uses rigid schemas for consistency, unlike JSON Database’s schema-less approach.
Data Lakes (C): Data lakes store raw, mixed-format data (e.g., JSON, CSV, Parquet) for later processing, typically in object storage, not a managed database like Autonomous JSON. While JSON Database handles JSON, it’s not a data lake replacement.
This workload leverages JSON Database’s agility for modern, unstructured data applications.
NEW QUESTION # 14
Which statement is true when you provision an Autonomous Database using the cloning method?
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 # 15
Which three Oracle Cloud Infrastructure (OCI) resources do you need to configure before provisioning your Autonomous Database with a private endpoint? (Choose three.)
Answer: A,B,E
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 # 16
Which three security features are available in Oracle Autonomous Database Shared Infrastructure? (Choose three.)
Answer: A,C,E
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 # 17
Where are the customer-managed encryption keys stored for Autonomous Database on Dedicated Infrastructure?
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.
