NEW QUESTION # 123
How many Network Security Groups (NSGs) can you configure for an Autonomous Database?
Answer: D
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 # 124
Which workload type does the Autonomous Database on dedicated infrastructure service currently support?
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 # 125
Which can be scaled independently of the number of CPUs in an Autonomous Database?
Answer: C
Explanation:
Autonomous Database allows independent scaling of certain resources:
Correct Answer (B): “Storage” can be scaled independently of OCPUs via the OCI Console or API, adjusting capacity (e.g., from 1 TB to 2 TB) without altering compute resources.
Incorrect Options:
A: Sessions depend on CPU and memory limits, not independently scalable.
C: Memory scales with OCPUs in a fixed ratio, not separately.
D, E: Concurrency and parallelism are tied to CPU resources and consumer group settings.
This flexibility optimizes cost and capacity management.
NEW QUESTION # 126
Which three security features are available in Oracle Autonomous Database Shared Infrastructure? (Choose three.)
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 # 127
Oracle Autonomous Database on Dedicated Infrastructure is composed of which Oracle Cloud resources?
Answer: C
Explanation:
Full Detailed In-Depth Explanation:
Autonomous Database on Dedicated Infrastructure comprises:
Autonomous Exadata Infrastructure: The hardware and software foundation.
Autonomous Container Database: Hosts multiple ADB instances.
Autonomous Database: The managed database instance.
Autonomous Backup: Automatic backups to OCI Object Storage.
Other options include roles (B, C) or general OCI resources (D), not core components of the service. A is the correct composition.
