Oracle 1z0-931-25 Actual Questions

Full Detailed In-Depth Explanation:

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.

Defining a maintenance schedule for Dedicated Exadata Infrastructure allows customization:

Correct Answer (B): “Month of the Quarter, Week of the Month, Day of the Week, Start Hour” is the correct set. For example, you can specify “Month 2 of Q1, Week 3, Wednesday, 02:00 AM,” aligning with quarterly planning while offering weekly and daily precision.

Incorrect Options:

A: “Quarter of the Year” and “Date of the Month” are less flexible than week-based options and not the standard format.

C: “Month of the Year” skips the quarterly structure used in dedicated maintenance.

Connecting a .NET application to Autonomous Database (ADB) requires a specific client library compatible with Oracle’s database connectivity standards. The correct software is:

Oracle Data Access Components for Windows (D):Oracle Data Access Components (ODAC) for Windows is the recommended software for .NET applications to connect to ADB. ODAC includes the Oracle Data Provider for .NET (ODP.NET), which supports ADO.NET interfaces for database access. It enables .NET developers to use familiar APIs (e.g., OracleConnection, OracleCommand) to interact with ADB over Oracle Net Services, leveraging the secure TLS connection required by ADB (via the client wallet). For example, a .NET app might use ODAC to execute SELECT * FROM customers against an ADB instance, authenticating with a wallet downloaded from the OCI console. ODAC supports both managed and unmanaged modes: the managed ODP.NET is lightweight and assembly-based, while the unmanaged version integrates with Oracle Client libraries. To set it up, developers install ODAC (e.g., via NuGet or Oracle’s download site), configure the wallet (e.g., tnsnames.ora), and write code like:

csharp

CollapseWrapCopy

using Oracle.ManagedDataAccess.Client;

string connString = "User Id=USER1;Password=pwd;Data Source=adb_high";

using (OracleConnection conn = new OracleConnection(connString)) {

conn.Open();

// Query execution here

}

This ensures seamless integration with ADB’s managed environment, supporting features like connection pooling and high performance.

The incorrect options are:

SQL*Plus (A):SQL*Plus is a command-line tool for SQL execution and administration, not a programmatic library for .NET applications. It’s unsuitable for embedding in a .NET app, as it lacks API integration and is meant for manual use (e.g., running scripts like SELECT * FROM table;).

You cannot use .NET with ADB (B):This is false. .NET is fully supported via ODAC, allowing applications (e.g., ASP.NET web apps or Windows services) to connect to ADB just like any Oracle database, provided the wallet and credentials are configured.

Java (C):Java uses JDBC (e.g., Oracle JDBC Driver) for database connectivity, not .NET. While JDBC works with ADB for Java apps, it’s irrelevant for a .NET environment, where ODAC is the standard.

ODAC’s robust support for .NET makes it the definitive choice, bridging Microsoft’s ecosystem with Oracle’s cloud database.

Full Detailed In-Depth Explanation:

Since only four options are provided but the format requests two answers, I’ll assume E from a prior question context. Let’s evaluate:

A:True but conditional. Database Actions is accessible with a Private Endpoint, but requires proper network setup (e.g., VCN peering), not guaranteed by default.

B:True. Oracle APEX is accessed exclusively via the “Developer” menu in the Service Console, not other interfaces.

C:False. Oracle Machine Learning (OML) is available in both ADW and ATP, not just ADW.

D:False. Database Actions access requires specific user privileges (e.g., DWROLE), not granted to all users by default.

E (assumed):True. SQL Developer Web is exclusive to Autonomous Database, not traditional Oracle databases.

B and E are the most definitively true statements per documentation.
