質問 # 23
A database administrator is new to a company and wants to create a document that illustrates the interaction between tables. Which of the following should the administrator create?
正解：A
解説：
The document that the administrator should create to illustrate the interaction between tables is an entity relationship diagram. An entity relationship diagram (ERD) is a graphical representation of the entities (tables), attributes (columns), and relationships (constraints) in a database. An ERD helps the administrator to visualize the structure and design of the database, as well as the dependencies and associations among the tables. The other options are either different types of documents or not related to the interaction between tables. For example, a troubleshooting guide is a document that provides instructions on how to solve common problems or errors in a database; a data dictionary is a document that describes the metadata (information about data) of a database; a database reference manual is a document that provides information on how to use or operate a database. 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 # 24
A database administrator would like to address data inconsistencies, define conventions to be used across the organization, make data easier to analyze, and enforce the use of data standards. Which of the following solutions would best meet the administrator's need?
正解：A
解説：
A data dictionary standardizes definitions and formats, helping enforce data consistency, conventions, and easier analysis across the organization.
質問 # 25
(New users at a company are reporting that the system is not accepting new credentials when the users are asked to change the credentials for the first time. Which of the following is the reason the credentials are being rejected?)
正解：C
解説：
The correct answer is D. Password policies. CompTIA DataSys+ emphasizes that password policies are a core component of authentication and security controls within database systems and enterprise environments.
When new users are required to change their credentials for the first time, the system typically enforces predefined password rules. If the new credentials do not meet these rules, the system will reject them automatically.
Password policies define specific requirements such as minimum password length, complexity (use of uppercase letters, lowercase letters, numbers, and special characters), password history, expiration intervals, and restrictions against using previously compromised or common passwords. In many environments, first- time password changes are subject to the strictest enforcement of these rules to ensure strong baseline security from the start of a user's lifecycle.
Option A, identity management, focuses on the creation, provisioning, and lifecycle management of user identities across systems. While identity management systems initiate the credential change process, they do not usually enforce the detailed rules that cause a password to be rejected. Option B, access controls, govern what resources a user can access after authentication, not whether a password itself is valid. Option C, service accounts, are non-interactive accounts used by applications or services and are unrelated to new end-user credential changes.
DataSys+ documentation highlights that authentication failures during credential updates are most commonly tied to policy enforcement, not permissions or account type. This includes scenarios where users unknowingly violate complexity rules or reuse default or temporary passwords that are explicitly disallowed.
Therefore, the rejection of new credentials during a first-time password change is best explained by password policies, making option D the most accurate and verified answer according to CompTIA DataSys+ principles.
質問 # 26
Which of the following describes a lock that allows concurrent transactions to access different records of the same table?
正解：C
解説：
A row-level lock permits multiple transactions to access different rows within the same table concurrently, improving concurrency and minimizing contention.
質問 # 27
A database is configured to use undo management with temporary undo enabled. An UPDATE is run on the table.
Which of the following describes where the undo is stored?
正解：D
解説：
When undo management with temporary undo is enabled, the undo data is stored in the temporary tablespace instead of the undo tablespace. The temporary tablespace is a tablespace that stores temporary data such as sort results or intermediate query results. The undo data is the data that records the changes made by transactions on the database. Undo data is used to roll back transactions in case of errors or failures, or to provide read consistency for concurrent queries. By storing undo data in the temporary tablespace, the database can reduce the space consumption and contention in the undo tablespace, and improve performance and scalability.
The other options are either incorrect or irrelevant for this question. For example, the system global area is a memory area that stores information shared by all sessions connected to an instance; the undo tablespace is a tablespace that stores undo data by default; the SYSAUX tablespace is a tablespace that stores auxiliary information for various database features.
