질문 # 88
Which of the following constraints is used to enforce referential integrity?
정답：B
설명：
The constraint that is used to enforce referential integrity is foreign key. A foreign key is a column or a set of columns in a table that references the primary key of another table. A primary key is a column or a set of columns in a table that uniquely identifies each row in the table. Referential integrity is a rule that ensures that the values in the foreign key column match the values in the primary key column of the reference table. Referential integrity helps maintain the consistency and accuracy of the data across related tables. The other options are either different types of constraints or not related to referential integrity at all. For example, a surrogate key is a column that is artificially generated to serve as a primary key, such as an auto-increment number or a GUID (Globally Unique Identifier); a unique key is a column or a set of columns in a table that uniquely identifies each row in the table, but it can have null values unlike a primary key; there is no such constraint as TID.
질문 # 89
Which of the following is the deployment phase in which a DBA ensures the most recent patches are applied to the new database?
정답：B
설명：
The deployment phase in which a DBA ensures the most recent patches are applied to the new database is upgrading. Upgrading is a process that updates an existing database system or software to a newer version or release that may include new features, enhancements, bug fixes, security patches, etc. Upgrading helps improve the performance, functionality, compatibility, and security of the database system or software. Upgrading can be done manually or automatically using tools or scripts provided by the vendor or developer. Upgrading can also involve testing, backup, migration, or rollback procedures to ensure the quality and reliability of the new version or release. The other options are either different deployment phases or not related to deployment at all. For example, importing is a process that transfers data from one source to another using files or formats; provisioning is a process that allocates resources such as servers, storage, network, etc., for a system or software; modifying is a process that changes existing data or objects in a database using commands or scripts. Reference: CompTIA DataSys+ Course Outline, Domain 2.0 Database Deployment, Objective 2.3 Given a scenario, update database systems.
질문 # 90
(A financial institution is running a database that contains PII. Database administrators need to provide table access to junior developers. Which of the following is the best option?)
정답：B
설명：
The correct answer is C. View creation. CompTIA DataSys+ places strong emphasis on protecting personally identifiable information (PII) while still enabling developers and analysts to perform their required tasks. In environments such as financial institutions, direct access to tables containing sensitive data presents a significant security and compliance risk, especially for junior developers who do not require full visibility of production data.
Creating views is a best-practice solution that allows database administrators to expose only the necessary columns and rows while hiding or excluding sensitive fields such as Social Security numbers, account numbers, or personal contact details. Views act as a controlled abstraction layer over the underlying tables, enabling developers to work with realistic data structures without direct access to raw PII. DataSys+ highlights views as an effective method for enforcing the principle of least privilege while maintaining usability and performance.
Option A, role assignment, is important for access control but is too broad on its own. Assigning a role may still allow access to sensitive columns unless combined with views or column-level permissions. Option B, data masking, is often used for non-production environments or dynamic data protection, but it may not be the best solution when developers need structured access to table data for development or testing purposes.
Option D, policy enforcement, refers to governance and administrative controls but does not directly provide a technical mechanism for safe table access.
CompTIA DataSys+ stresses that database security should balance protection with operational efficiency.
Views allow DBAs to centrally manage what data is exposed, simplify auditing, and reduce the risk of accidental data leakage. They are especially valuable in regulated industries where compliance and data minimization are critical.
Therefore, the best option for providing junior developers with access while protecting PII is view creation, making option C the correct and fully verified answer.
질문 # 91
Which of the following NFs is considered the most preferable for relational database design?
정답：B
설명：
The NF (normal form) that is considered the most preferable for relational database design is 3 NF. 3 NF, or Third Normal Form, is a level of normalization that organizes data into tables and columns to reduce redundancy and improve consistency. Normalization is a process that applies a set of rules or criteria to eliminate or minimize the anomalies or problems that may arise from inserting, updating, or deleting data in a database. 3 NF is achieved when a table satisfies the following conditions: - It is in 2 NF (Second Normal Form), which means that every non-key column depends on the whole primary key and not on any subset of it - It has no transitive dependencies, which means that every non-key column depends directly on the primary key and not on any other non-key column 3 NF is considered the most preferable for relational database design because it ensures that each table has only one purpose or theme and that each column has only one value or meaning. This helps avoid data duplication, inconsistency, and update anomalies. The other options are either lower or higher levels of normalization that are either less preferable or less practical for relational database design. For example, 1 NF (First Normal Form) is the lowest level of normalization that requires each column to have atomic values and each row to have a unique identifier; 4 NF (Fourth Normal Form) is a higher level of normalization that requires each table to have no multi-valued dependencies, which means that there are no columns that can have more than one value for the same primary key value; 2 NF (Second Normal Form) is an intermediate level of normalization that requires each non-key column to depend on the whole primary key and not on any subset of it.
질문 # 92
Which of the following cloud storage options provides users with endpoints to retrieve data via REST API?
정답：A
설명：
The cloud storage option that provides users with endpoints to retrieve data via REST API is object. Object storage is a type of cloud storage that stores data as objects, which consist of data, metadata, and a unique identifier. Object storage does not use any hierarchy or structure to organize data, but rather uses flat namespaces that allow users to access data using the unique identifier. Object storage also provides users with endpoints to retrieve data via REST API (Representational State Transfer Application Programming Interface), which is a standard way of communicating with web services using HTTP methods (such as GET, POST, PUT, DELETE) and formats (such as JSON, XML). Object storage is suitable for storing large amounts of unstructured data that do not require frequent changes or complex queries. The other options are either different types of cloud storage or not related to cloud storage at all. For example, network file storage is a type of cloud storage that stores data as files in folders using protocols such as NFS (Network File System) or SMB (Server Message Block); ephemeral storage is a type of temporary storage that stores data only for the duration of a session or process; iBIock is not a valid acronym or type of cloud storage.
