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.

Oracle Data Safe enhances database security across various deployments. Let’s evaluate:

A:True. Data Safe assesses cloud database configurations for vulnerabilities.

B:True. It evaluates user authentication, types, and password policies.

C:False. Data Safe supports Autonomous Databases, Exadata Cloud Service, OCI VMs, and on-premises Oracle databases, not just Autonomous Databases.

D:True. It scans data and metadata to identify sensitive information.

Option C is the false statement, as Data Safe’s scope extends beyond Autonomous Databases.

Full Detailed In-Depth Explanation:

A:False. APEX is for app development, not data exploration.

B:False. SQL Developer Web is for SQL queries, not pivot tables.

C:True. Business Models in ADW automates data exploration and generates pivot tables.

D:False. Data Load is for importing data, not analysis.

Full Detailed In-Depth Explanation:

Connecting a marketplace OCI image (e.g., a pre-configured VM) to an Autonomous Database on Shared Infrastructure involves network and compatibility considerations. Let’s analyze each option:

A. The Autonomous Database must belong to a Network Security Group (NSG):False. NSGs enhance security but are optional. Connectivity can be achieved without them using security lists or other rules.

B. The marketplace OCI image can be used with an Always Free Autonomous Database account:True. The Always Free tier supports connectivity from OCI marketplace images, provided network configurations (e.g., VCN, subnet) allow it. This makes B the correct answer.

C. A Private Endpoint is required to connect to the Autonomous Database on Shared Exadata infrastructure:False. While private endpoints enhance security, public endpoints are also supported for shared infrastructure, making this optional.

D. The marketplace OCI image does not support connecting to an AutonomousDatabase on Shared Infrastructure:False. Marketplace images are designed to integrate with OCI services, including Autonomous Databases on shared infrastructure.

Option B stands out as it aligns with Oracle’s support for Always Free tiers, offering flexibility for users to leverage marketplace tools without additional cost.

Scaling resources in Autonomous Database offers flexibility. The true statement is:

OCPUs and storage can be scaled independently (A):In Autonomous Database, you can adjust the number of OCPUs (compute resources) and storage capacity (in terabytes) separately via the OCI console or CLI. For example, you might provision an ADB with 2 OCPUs and 1 TB of storage. Later, you could scale to 4 OCPUs without changing storage, or increase storage to 2 TB without touching OCPUs. This decoupling allows tailored resource allocation—e.g., more compute for a CPU-intensive workload or more storage for growing data—without over-provisioning. Scaling is online, with no downtime, and status shows “SCALING IN PROGRESS” during the operation.

The incorrect options are:

Use auto scaling to increase storage (B):Auto scaling applies to OCPUs only, allowing up to 3x the base CPU allocation dynamically. Storage scaling is manual; you specify a new size (e.g., via oci db autonomous-database update), not via auto scaling.

Increasing OCPUs will automatically increase storage (C):There’s no automatic linkage between OCPU and storage scaling. They are independent parameters, and increasing one does not affect the other unless explicitly requested.

OCPUs and storage must remain in sync (D):No such synchronization is required. You can have 1 OCPU with 10 TB or 10 OCPUs with 1 TB, depending on workload needs.

This independence is a hallmark of Autonomous Database’s elasticity.

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.
