DS0-001 Exam Dumps : CompTIA DataSys+ Certification Exam

The correct order of the steps in the database deployment process is option C. This order follows the best practices for deploying a database system, which are:

• Confirm prerequisites: Check the system requirements and compatibility of the database software and tools before installation.
• Install: Install the database software and tools on the target server or platform.
• Configure: Configure the database settings and parameters according to the specifications and needs of the application or organization.
• Connect: Connect the database to the network and other systems or applications that will access it.
• Test: Test the functionality and performance of the database system and verify that it meets the expectations and requirements.
• Validate: Validate the data quality and integrity of the database system and ensure that it complies with the standards and regulations.
• Release: Release the database system to production and make it available for use by end-users or customers. The other options do not follow this order and may result in errors, inefficiencies, or security issues. References: CompTIA DataSys+ Course Outline, Domain 2.0 Database Deployment, Objective 2.1 Given a scenario, install and configure database software and tools.

A scenario in which a database administrator would use a relational database rather than a non-relational database is when an organization wants to maintain consistency among the data in the database. A relational database is a type of database that organizes data into tables with predefined columns and rows, and enforces rules and constraints to ensure data integrity and accuracy. A relational database also supports transactions, which are sets of operations that must be executed as a whole or not at all, to prevent data corruption or inconsistency. The other options are either not exclusive to relational databases or not relevant to the choice of database type. For example, data encryption can be applied to both relational and non-relational databases, processing complex data sets may require specialized tools or techniques that arenot dependent on the database type, and storing a large number of videos, photos, and documents may be better suited for a non-relational database that can handle unstructured or semi-structured data. References: CompTIA DataSys+ Course Outline, Domain 1.0 Database Fundamentals, Objective 1.1 Given a scenario, identify and apply database structure types.

The approach that the administrator should use when conducting the stress test is to capture business logic, check the performance of codes, and report findings. This will help the administrator to evaluate how well the application handles high volumes of data and transactions, identify any bottlenecks or errors in the code, and provide feedback to the development team on how to improve the application’s efficiency and reliability. The other options are either too narrow or too broad in scope, and do not address the specific needs of an application that uses the Entity Framework. References: CompTIA DataSys+ Course Outline, Domain 4.0 Data and Database Security, Objective 4.3 Given a scenario, monitor database performance and security.
