質問 # 26
A database administrator is concerned about transactions in case the system fails. Which of the following properties addresses this concern?
正解：D
解説：
The property that addresses this concern is durability. Durability is one of the four properties (ACID) that ensure reliable transactions in a database system. Durability means that once a transaction has been committed, its effects are permanent and will not be lost in case of system failure, power outage, crash, etc. Durability can be achieved by using techniques such as write-ahead logging, checkpoints, backup and recovery, etc. The other options are either not related or not specific to this concern. For example, isolation means that concurrent transactions do not interfere with each other and produce consistent results; atomicity means that a transaction is either executed as a whole or not at all; consistency means that a transaction preserves the validity and integrity of the data. Reference: CompTIA DataSys+ Course Outline, Domain 1.0 Database Fundamentals, Objective 1.3 Given a scenario, identify common database issues.

Which of the following is the best alternative to control the temperature in a data center?
正解：D
解説：
Redundant air conditioning units provide reliable temperature control in data centers, ensuring continuous cooling even if one unit fails, which is critical for preventing overheating.

(An IT manager needs to create a workflow for a new application. Which of the following tools should the manager use to facilitate the creation of a workflow?)
正解：A
解説：
The correct answer is B. UML. CompTIA DataSys+ identifies Unified Modeling Language (UML) as a standard visual modeling tool used to design, document, and communicate system behavior, structure, and workflows during application development. UML is especially well-suited for creating workflows because it provides multiple diagram types that clearly represent processes, interactions, and control flow within an application.
Common UML diagrams used for workflow modeling include activity diagrams, which show step-by-step business or system processes, and sequence diagrams, which illustrate interactions between system components over time. These diagrams help stakeholders understand how users, systems, and data interact throughout an application's lifecycle. DataSys+ emphasizes that UML improves collaboration between technical and non-technical stakeholders by providing a clear, standardized visual representation of application logic and flow.
Option A, ERD (Entity Relationship Diagram), is used to model database structure, including entities, attributes, and relationships. While ERDs are essential for schema design, they do not describe application workflows or process logic. Option C, ETL (Extract, Transform, Load), refers to data integration processes used in data warehousing and analytics; it is not a design or modeling tool for application workflows. Option D, ORM (Object-Relational Mapping), is a programming abstraction layer that maps application objects to database tables and does not provide workflow visualization capabilities.
CompTIA DataSys+ highlights the importance of proper planning and design tools during application development. UML enables IT managers to map workflows before implementation, reducing development errors, improving maintainability, and ensuring that business requirements are met.
Therefore, the most appropriate tool for facilitating the creation of a workflow for a new application is UML, making option B the correct and fully verified answer.
質問 # 29
A company needs information about the performance of users in the sales department. Which of the following commands should a database administrator use for this task?
正解：D
解説：
The command that the database administrator should use for this task is SELECT. The SELECT command is a SQL statement that retrieves data from one or more tables or views in a database. The SELECT command can also use various clauses or options to filter, group, sort, or aggregate data according to specific criteria or conditions. By using the SELECT command, the database administrator can obtain information about the performance of users in the sales department, such as their sales volume, revenue, commission, etc. The other options are either not related or not suitable for this task. For example, DROP is a SQL command that deletes an existing table or object from a database; UPDATE is a SQL command that modifies existing data in one or more rows of a table; DELETE is a SQL command that removes existing data from one or more rows of a table. References: 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 # 30
(Which of the following best describes the function of a wildcard in the WHERE clause?)
正解：D
解説：
The correct answer is C. An exact match is not possible in a SELECT statement. CompTIA DataSys+ documentation explains that wildcards are used in SQL primarily within the WHERE clause of a SELECT statement to enable pattern matching rather than exact value matching. Wildcards such as % and _ are commonly used with the LIKE operator to search for partial strings or variable patterns in character-based data.
In practical database usage, wildcards allow analysts and administrators to retrieve records when the full or exact value is unknown or unnecessary. For example, searching for all patient records with last names starting with "Mac%" or all email addresses ending in "@example.com" requires pattern-based matching. In these cases, an exact match is explicitly not required, which is the core purpose of wildcards in SQL queries.
Option A and D incorrectly reference the CREATE statement. Wildcards are not relevant to CREATE statements, which are used for defining database objects such as tables, indexes, or views. These statements require explicit definitions and do not support wildcard-based matching logic. Option B is also incorrect because a SELECT statement does not always require an exact match; this is precisely why wildcards exist and are heavily used in querying operations.
CompTIA DataSys+ emphasizes that understanding query flexibility is essential for data retrieval and reporting. Wildcards enhance query usability and efficiency by allowing broader result sets without complex logic or multiple conditions. They are particularly valuable in analytical, reporting, and troubleshooting scenarios where partial data exploration is required.
Therefore, the best description of the function of a wildcard in the WHERE clause is that it allows queries where an exact match is not required, making option C the correct and fully aligned answer according to CompTIA DataSys+ principles.
