NEW QUESTION # 18
Which of the following DR techniques uses a disk to update content in parallel with the main disk so a real-time backup is available?
Answer: C
Explanation:
Mirroring maintains a real-time copy of data by writing simultaneously to a secondary disk, ensuring an up-to-date backup is always available.
NEW QUESTION # 19
A database administrator is assisting developers with finding the best tables and columns to include in an application. Which of the following resources is the most relevant for this task?
Answer: A
Explanation:
A data dictionary provides detailed information about database tables, columns, and their attributes, helping developers understand the structure and relationships to select the best tables and columns for the application.
NEW QUESTION # 20
Which of the following constraints is used to enforce referential integrity?
Answer: B
Explanation:
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 referenced 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.

NEW QUESTION # 21
(Which of the following best describe a tablespace? Select two.)
Answer: C,F
Explanation:
The correct answers are D. It can contain more than one data file and F. It can be used to organize data in a database. CompTIA DataSys+ describes a tablespace as a logical storage container used by a database to organize how data is physically stored on disk. Tablespaces provide an abstraction layer between the logical database objects and the physical storage files.
A tablespace can include multiple data files, which allows database administrators to distribute data across different disks or storage systems. This capability supports scalability, performance optimization, and high availability. By adding or resizing data files within a tablespace, administrators can expand storage capacity without restructuring the database schema. DataSys+ highlights this as a key advantage for capacity planning and storage management.
Tablespaces are also used to organize data within a database. Different tablespaces can be created for different purposes, such as separating user data, indexes, temporary data, and system metadata. This organization improves performance tuning, simplifies backup and recovery operations, and enhances manageability. For example, placing indexes in a separate tablespace from table data can reduce I/O contention.
Option A is incorrect because a tablespace belongs to a single database and cannot span multiple databases.
Option B is misleading; while tablespaces map to data files, blocks are allocated within files, not mixed arbitrarily across files. Option C is incorrect because segments are allocated in extents, and their sizing behavior is controlled by storage parameters, not defined as a primary purpose of tablespaces. Option E is incorrect because tablespaces represent disk-based storage, not memory-resident structures.
CompTIA DataSys+ emphasizes understanding logical versus physical storage concepts. Tablespaces play a central role in bridging these concepts by organizing data logically while enabling flexible physical storage management. Therefore, the best descriptions of a tablespace are D and F, making them the correct and verified answers.
NEW QUESTION # 22
(Five minutes after a power failure occurred in a data center, a CO# system was automatically triggered.
Which of the following caused the CO# system to start?)
Answer: D
Explanation:
The correct answer is A. High temperatures activated the fire suppression system. According to CompTIA DataSys+ objectives, physical infrastructure protections are a critical component of database and data center reliability. CO# fire suppression systems are specifically designed to respond to fire-related conditions, not recovery metrics or cooling system logic. These systems are typically triggered by smoke detectors, heat sensors, or rapid temperature increases that indicate a fire or imminent fire risk following an event such as a power failure.
When a power outage occurs, backup systems such as generators and uninterruptible power supplies may activate. If these systems malfunction or generate excessive heat, temperature thresholds can be exceeded within minutes. DataSys+ materials emphasize that automated environmental controls are designed to protect equipment and data by suppressing fires quickly, often before flames are visible. CO# systems work by displacing oxygen, thereby extinguishing fire without damaging sensitive electronic equipment with water or chemical residue.
Options B and D are incorrect because RPO (Recovery Point Objective) and RTO (Recovery Time Objective) are disaster recovery planning metrics. RPO defines acceptable data loss measured in time, while RTO defines acceptable downtime. Neither setting directly triggers physical fire suppression systems. They are planning and policy metrics, not automated environmental controls.
Option C is also incorrect because cooling systems do not activate CO# fire suppression. Cooling failures may indirectly contribute to rising temperatures, but the CO# system itself is triggered by fire detection mechanisms, not by cooling system logic.
CompTIA DataSys+ clearly distinguishes between environmental controls (fire suppression, HVAC, power) and disaster recovery metrics (RPO, RTO). Therefore, option A best aligns with documented data center operational behavior and exam objectives.
