Oracle 1Z0-931-25 Exam Dumps

Connecting an OCI Marketplace image (e.g., a compute instance running a preconfigured application) to a shared Autonomous Database (ADB) involves network configuration. The correct statement is:

Compute Image and Shared ADB must be in the same VCN and Subnet (A): For a compute instance from the OCI Marketplace to communicate with a shared Autonomous Database, both must reside in the same Virtual Cloud Network (VCN) and subnet. This ensures direct network connectivity without requiring complex routing or public internet traversal. By default, shared ADB instances use private endpoints within a VCN, and placing the compute instance in the same subnet allows seamless access using the database's private IP address. For example, if the ADB is in subnet 10.0.1.0/24, the compute instance must also be in that subnet to connect via Oracle Net Services (e.g., using a wallet and tnsnames.ora).

The incorrect options are:

ADB must be configured with Private endpoints (B): While shared ADB instances are configured with private endpoints by default (not publicly accessible), this is not a configurable option you ''must'' set---it's inherent to shared infrastructure. Thus, it's not a requirement you actively enforce for this scenario; it's already true.

ADB must be configured with NSG (C): Network Security Groups (NSGs) are optional for controlling traffic to an ADB. You can use NSGs for finer-grained security, but they are not mandatory; Security Lists at the subnet level can suffice. Hence, this is not a universal requirement for connectivity.

Cannot connect OCI Marketplace image to shared ADB (D): This is false. OCI Marketplace images (e.g., a web server or analytics tool) can connect to a shared ADB, provided network and authentication prerequisites (like same VCN/subnet and client credentials) are met.

This requirement simplifies network setup and enhances security by keeping communication internal to the VCN. For instance, a Marketplace image like a web application could query an ADB in the same subnet using JDBC or ODBC, leveraging the private endpoint.

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.

Full Detailed In-Depth Explanation:

When restoring or cloning an Autonomous Database (ADB), Oracle enforces a minimum backup age to ensure data consistency and integrity. The official Oracle documentation specifies that backups used for these operations must be at least 24 hours old. This requirement exists because:

Backups need time to complete and stabilize, ensuring all transactions are fully committed and the backup is consistent.

Recent backups (e.g., less than 24 hours old) may still be in progress or lack full verification, risking incomplete or corrupted restores/clones.

Options B (5 minutes), C (2 hours), and D (1 day) are either too short or redundant:

5 minutes and 2 hours: Too recent, violating the 24-hour rule.

1 day: Matches 24 hours but is less precise than the explicit ''24 hours'' phrasing in the documentation.

For the Business Analyst's exploration, they can access tools like SQL Developer Web or Data Load via the OCI Console under the ''Tools'' tab, but this question focuses on the backup age constraint, making A the best answer.

Oracle provides specialized index types for different data indexing needs. The correct answer is:

CTXCAT (B): The CTXCAT index type is specifically designed for indexing catalog information, such as product catalogs or structured data with short text fields. It supports fast queries on structured data combined with text search, making it ideal for applications like e-commerce catalogs.

The incorrect options are:

CONTEXT (A): The CONTEXT index is used for full-text search on large unstructured text data (e.g., documents), not specifically for catalog information.

CTXRULE (C): The CTXRULE index is designed for rule-based classification of text, not for catalog indexing.

CONSTRAINS (D): This appears to be a typo (likely meant 'CONSTRAINTS'), but constraints are not index types; they enforce data integrity rules, not indexing.

CTXCAT enhances performance for catalog-style queries, distinguishing it from other text index types.

Fleet administrators managing dedicated Exadata infrastructure in Oracle Autonomous Database require broad permissions across all Autonomous Database resources, including those on dedicated infrastructure.

Correct Answer (B): The policy Allow group adb-admins to manage autonomous-database-family in tenancy grants comprehensive management rights over the entire Autonomous Database family, including dedicated Exadata infrastructure. The autonomous-database-family resource type encompasses all Autonomous Database resources (shared and dedicated) within the tenancy, making it suitable for fleet admins.

Incorrect Options:

A: Limits permissions to databases with the OLTP workload type (Autonomous Transaction Processing), excluding Data Warehouse (DW) or other types on dedicated infrastructure.

C: Restricts access to DW workload types only, omitting OLTP and other configurations.

D: Grants permissions only to autonomous-database resources, which may not fully cover dedicated infrastructure components like Autonomous Container Databases or Exadata Infrastructure.

This policy ensures fleet admins have the necessary scope to manage all aspects of dedicated deployments.
