A "MySQL Database Service DB System" includes a "Compute Instance" (A) for processing, a "Virtual Network Interface" (B) for networking, and "Block Storage" (D) for data. "FastConnect" (C), a high-speed connectivity service to OCI, is not a component of the DB system itself but an optional external connection. Oracle’s MySQL Service documentation lists the core components, excluding FastConnect.

Question 2
Which security measure is implemented out-of-the-box, and is included if you are not using BYOL licensing with Exadata Cloud@Customer?
Options:
A.
Oracle Key Vault
B.
Audit Vault and Database Firewall
C.
Database Vault and Data Masking Pack
D.
Oracle Native Network Encryption and TDE (Transparent Data Encryption)
Answer:
D
Explanation:
For "Exadata Cloud@Customer" without Bring Your Own License (BYOL), "Oracle Native Network Encryption and TDE (Transparent Data Encryption)" (D) are implemented out-of-the-box. Native Network Encryption secures data in transit, while TDE encrypts data at rest, both enabled by default to ensure baseline security compliance. "Oracle Key Vault" (A), "Audit Vault and DatabaseFirewall" (B), and "Database Vault and Data Masking Pack" (C) are advanced security options requiring additional configuration or licensing, not automatically included without BYOL. Oracle’s Exadata Cloud@Customer documentation confirms these encryption features as standard.
What set of NoSQL-style APIs can be used in Autonomous JSON Database?
Options:
A.
OASD (Oracle Application Storage Definition)
B.
SODA (Simple Oracle Document Access)
C.
DOSA (Document Open Solution Access)
D.
OSDA (Oracle Simple Document Access)
Answer:
B
Explanation:
The "Autonomous JSON Database" supports NoSQL-style document access through "SODA" (Simple Oracle Document Access) APIs (B). SODA provides a simple, intuitive interface for developers to interact with JSON documents stored in the database using operations like insert, query, and update, without requiring SQL knowledge. Options A ("OASD"), C ("DOSA"), and D ("OSDA") are not recognized API sets in Oracle’s documentation. SODA is explicitly documented as the standard NoSQL API for Autonomous JSON Database, aligning with Oracle’s converged database strategy to support multiple data models.
