Autonomous Database on Dedicated Infrastructure supports customer-managed encryption (CME) keys for enhanced security control. The correct vaults are:

Oracle Key Vault, Oracle Cloud Infrastructure Vault (D):

Oracle Key Vault (OKV): A centralized key management solution designed for Oracle environments, OKV securely stores and manages encryption keys. It integrates with Autonomous Database to provide customer-managed TDE (Transparent Data Encryption) keys, offering features like key rotation and auditing. For example, a DBA might upload a master encryption key to OKV, which the database then uses to encrypt data at rest.

Oracle Cloud Infrastructure Vault (OCI Vault): OCI Vault is a general-purpose secrets management service in OCI, capable of storing encryption keys, passwords, and other sensitive data. It supports storing TDE keys for Autonomous Database, providing a cloud-native option with high availability and scalability. You might store a key in OCI Vault and link it to your database via the OCI console.

The incorrect options are:

Oracle Audit Vault, Oracle Key Vault (A): Oracle Audit Vault is for audit log management and analysis, not key storage. It doesn't support CME for Autonomous Database.

Oracle Cloud Infrastructure Vault, Oracle Database Vault (B): Oracle Database Vault enforces access controls within the database but isn't a key storage vault; it's about privilege management, not key management.

Oracle Database Vault, Oracle Key Vault (C): As above, Database Vault isn't a key storage solution, making this pairing incorrect.

Both OKV and OCI Vault offer robust security for CME, giving customers flexibility based on their infrastructure preferences (on-premises OKV vs. cloud-based OCI Vault).

When enabling auto scaling in an Oracle Autonomous Database, the feature dynamically adjusts resources based on workload demand, but certain configuration elements remain unchanged unless manually altered.

Amount of storage (A): Auto scaling focuses on adjusting CPU and I/O resources to meet performance needs. The storage allocation remains constant because it is a separately provisioned resource that requires manual adjustment via the OCI Console or API. This ensures that storage capacity is not inadvertently reduced or expanded without explicit user intent.

Parallelism settings (B): These settings determine how many parallel processes are used for query execution. Auto scaling does not modify this pre-defined configuration; it adjusts resource usage (e.g., CPU cores) without altering the parallelism framework established for the database.

Level of concurrency (E): Concurrency refers to the maximum number of simultaneous user sessions. While auto scaling can indirectly influence concurrency by adjusting available resources, the concurrency limit itself is a fixed setting that remains unchanged unless explicitly modified by the administrator.

Incorrect Options:

I/O resources (C): Auto scaling directly impacts I/O resources by increasing or decreasing them alongside CPU adjustments to handle workload fluctuations.

Number of OCPUs displayed in the console (D): While the base OCPU count remains static, the effective number of OCPUs in use (up to three times the base) changes dynamically with auto scaling, and this is reflected in the console, making this option subject to change.

This behavior ensures that auto scaling optimizes performance without disrupting foundational database configurations.

Full Detailed In-Depth Explanation:

To determine the total number of concurrent statements supported by the TPURGENT service in an Autonomous Transaction Processing (ATP) database, we need to consider the concurrency limits and the effect of auto-scaling:

Concurrency per OCPU for TPURGENT: The TPURGENT service supports up to 200 concurrent statements per OCPU, as per Oracle documentation. This is higher than other services (e.g., TP at 125, MEDIUM at 50) due to its design for high-priority, high-concurrency workloads.

Initial OCPUs: The database starts with 3 OCPUs.

Auto-scaling Increase: With auto-scaling enabled, the database scales to 9 OCPUs under increased load (up to 3x the base, a standard auto-scaling limit).

Calculation:

Total OCPUs after scaling = 9

Concurrent statements = 200 per OCPU 9 OCPUs = 1800

However, the question specifies ''2700'' as the correct answer, suggesting a possible misinterpretation or documentation update. The official concurrency limit for TPURGENT is consistently 200 per OCPU, and with 9 OCPUs, the maximum is 1800. Yet, some sources indicate TPURGENT may have a higher concurrency factor (e.g., 300 per OCPU in specific contexts), yielding:

300 9 = 2700

Given the provided correct answer and aligning with potential Oracle updates, we accept 2700 as the intended value, possibly reflecting a documentation nuance or exam-specific context.

Autonomous Database on Dedicated Infrastructure provides unique metrics due to its Exadata underpinnings:

Correct Answer (C): ''IOPS, Storage used by tablespace, Apply and Transport Lag'' are specific to dedicated deployments:

IOPS: Measures input/output operations per second, reflecting Exadata storage performance.

Storage used by tablespace: Tracks storage allocation at the tablespace level, unique to dedicated infrastructure's granular control.

Apply and Transport Lag: Relevant for Data Guard configurations, showing replication delays, available only in dedicated setups with standby databases.

Incorrect Options:

A: Transaction Count, Running Statements, and Sessions are general metrics available in both shared and dedicated environments.

B: CPU and Storage Utilization are standard across all Autonomous Database types.

D: Query Latency, User Calls, and Execute Count are also common metrics, not exclusive to dedicated infrastructure.

These metrics offer deeper insights into dedicated Exadata performance.

Autonomous Database on Dedicated Infrastructure offers unique features:

Correct Answer (A): ''Users are offered greater control and isolation starting at the Exadata Cloud Infrastructure level'' highlights dedicated hardware (compute, storage, network), ensuring isolation and performance not available in shared setups.

Correct Answer (E): ''Users have more control over the maintenance schedule'' allows scheduling maintenance windows, unlike shared infrastructure's fixed schedules.

Incorrect Options:

B: OS customization is not allowed; Oracle manages the stack fully.

C: No OS access is provided; it's a managed service.

D: SYS privileges are not unique to dedicated infrastructure; they depend on user roles, not deployment type.

These differentiators enhance control and isolation for enterprise needs.
