CompTIA DataSys+ Certification Exam 認定 DS0-001 試験問題 (Q24-Q29):

質問 # 24
A database professional is considering denormalizing a database. Which of the following documents should be used to analyze the database's structure?

正解：C

解説：
The document that should be used to analyze the database's structure is an ERD. An ERD, or Entity Relationship Diagram, is a graphical representation of the entities (tables), attributes (columns), and relationships (constraints) in a database. An ERD helps to visualize the structure and design of the database, as well as the dependencies and associations among the tables. An ERD can also help to evaluate the level of normalization of the database, which is a process that organizes data into tables and columns to reduce redundancy and improve consistency. By using an ERD, a database professional can consider denormalizing a database, which is a process that introduces some redundancy or duplication of data to improve performance or simplify queries.
The other options are either different types of documents or not related to the database's structure. For example, an SOP, or Standard Operating Procedure, is a document that describes the steps and procedures for performing a specific task or operation; a data dictionary is a document that describes the metadata (information about data) of a database; a UML diagram is a graphical representation of a software system or its components using the Unified Modeling Language (UML).


質問 # 25
Which of the following best describes the category of SQL commands required to revoke access to database objects?

正解：B

解説：
The category of SQL commands that is required to revoke access to database objects is DCL. DCL, or Data Control Language, is a subset of SQL commands that are used to control or manage the access or permissions of users or roles on a database. DCL includes commands such as GRANT and REVOKE. GRANT is a DCL command that is used to grant privileges or roles to users or roles on specific objects in a database, such as tables, views, procedures, etc. REVOKE is a DCL command that is used to revoke privileges or roles from users or roles on specific objects in a database. For example, the following statement uses the REVOKE command to revoke the SELECT privilege from user Alice on table employee:
REVOKE SELECT ON employee FROM Alice;
The other options are either different categories of SQL commands or not related to SQL commands at all. For example, IDDL is not a valid acronym or category of SQL commands; IDML is not a valid acronym or category of SQL commands; TCL, or Transaction Control Language, is a subset of SQL commands that are used to control or manage transactions on a database, such as committing or rolling back changes. Reference: CompTIA DataSys+ Course Outline, Domain 4.0 Data and Database Security, Objective 4.2 Given a scenario, implement security controls for databases.


質問 # 26
Which of the following is used to write SQL queries in various programming languages?

正解：C

解説：
The option that is used to write SQL queries in various programming languages is object-relational mapping. Object-relational mapping (ORM) is a technique that maps objects in an object-oriented programming language (such as Java, Python, C#, etc.) to tables in a relational database (such as Oracle, MySQL, SQL Server, etc.). ORM allows users to write SQL queries in their preferred programming language without having to deal with the differences or complexities between the two paradigms. ORM also provides users with various benefits such as code reuse, abstraction, validation, etc. The other options are either not related or not effective for this purpose. For example, indexing is a technique that creates data structures that store the values of one or more columns of a table in a sorted order to speed up queries; Excel is a software application that allows users to organize and manipulate data in rows and columns; normalization is a process that organizes data into tables and columns to reduce redundancy and improve consistency. Reference: CompTIA DataSys+ Course Outline, Domain 1.0 Database Fundamentals, Objective 1.2 Given a scenario, execute database tasks using scripting and programming languages.


質問 # 27
Which of the following is a reason to create a stored procedure?

正解：B

解説：
A reason to create a stored procedure is to improve performance. A stored procedure is a set of SQL statements or commands that are stored and compiled in the database server, and can be executed by name or by a trigger. A stored procedure can improve performance by reducing the network traffic between the client and the server, as only the name or the parameters of the stored procedure need to be sent, rather than the entire SQL code. A stored procedure can also improve performance by reusing the same execution plan, as the stored procedure is compiled only once and cached in the server memory. The other options are either not true or not relevant for this purpose. For example, a stored procedure does not necessarily minimize storage space, as it still occupies space in the database server; a stored procedure does not bypass case sensitivity requirements, as it still follows the rules of the database system; a stored procedure does not give control of the query logic to the user, as it is defined and maintained by the database administrator or developer. References: CompTIA DataSys+ Course Outline, Domain 2.0 Database Deployment, Objective 2.2 Given a scenario, create database objects using scripting and programming languages.


質問 # 28
(Which of the following statements is TRUNCATE an example of?)

正解：B

解説：
The correct answer is A. DDL statement. CompTIA DataSys+ clearly classifies the TRUNCATE statement as a Data Definition Language (DDL) operation because it affects the structure and allocation of database objects rather than manipulating individual rows in a transactional manner.
TRUNCATE is used to quickly remove all rows from a table while preserving the table structure itself.
Unlike DELETE, which is a Data Manipulation Language (DML) statement that removes rows one by one and can be rolled back in many database systems, TRUNCATE operates by deallocating data pages. This makes it significantly faster and more efficient for clearing large tables, but also more destructive in nature.
DataSys+ emphasizes that DDL operations are typically auto-committed, meaning they cannot be rolled back once executed in most implementations.
Option D, DML, is incorrect because DML statements (such as SELECT, INSERT, UPDATE, and DELETE) work at the row level and are designed for routine data manipulation within existing structures. TRUNCATE does not qualify because it bypasses row-level logging and transactional controls. Option B, DCL (Data Control Language), is used for permission and access management (e.g., GRANT, REVOKE) and has no role in data removal. Option C, MCL, is not a recognized SQL command category and is therefore invalid.
CompTIA DataSys+ materials stress the importance of understanding SQL command categories, particularly the risks associated with DDL statements. Because TRUNCATE is fast, non-transactional, and irreversible in most cases, it should be used cautiously and typically only by administrators. Its classification as DDL is essential knowledge for exam objectives related to database operations, data safety, and change management.
Therefore, the correct and verified classification of TRUNCATE is DDL, making option A the correct answer.
