NEW QUESTION # 108
Which of the following best describes a collection of data that shares the same properties or attributes?
Answer: A
Explanation:
The option that best describes a collection of data that shares the same properties or attributes is entity set. An entity set is a term used in the entity-relationship (ER) model, which is a conceptual model for designing and representing databases. An entity set is a collection of entities that have the same type or characteristics, such as students, courses, products, etc. An entity is an object or thing that can be identified and distinguished from others, such as a specific student, course, product, etc. An entity set can have one or more attributes that describe the properties or features of the entities, such as name, age, price, etc. An entity set can also have one or more relationships with other entity sets that define how the entities are associated or connected, such as enrolled, taught by, purchased by, etc. The other options are either different terms or not related to the ER model at all. For example, relation set is a term used in the relational model, which is a logical model for implementing and manipulating databases; ER model is a term used to refer to the entity-relationship model itself; tuples are rows or records in a table or relation.
NEW QUESTION # 109
A database administrator is migrating the information in a legacy table to a newer table. Both tables contain the same columns, and some of the data may overlap.
Which of the following SQL commands should the administrator use to ensure that records from the two tables are not duplicated?
Answer: B
Explanation:
The SQL command that the administrator should use to ensure that records from the two tables are not duplicated is option A. This command uses the UNION clause to combine the records from the legacy table and the newer table into a single result set. The UNION clause also eliminates any duplicate records that may exist in both tables, and sorts the result by default. The other options either do not produce the desired result or have syntax errors. For example, option B would join the records from the two tables based on a common column, but not remove any duplicates; option C would return only the records that are common to both tables, but not the ones that are unique to each table; option D would produce a Cartesian product of the records from the two tables, which would increase the number of duplicates.

NEW QUESTION # 110
A company is launching a proof-of-concept, cloud-based application. One of the requirements is to select a database engine that will allow administrators to perform quick and simple queries on unstructured dat a. Which of the following would be best suited for this task?
Answer: A
Explanation:
The best suited database engine for this task is MongoDB. MongoDB is a type of non-relational database that stores data as documents in JSON-like format. MongoDB allows administrators to perform quick and simple queries on unstructured data, such as text, images, videos, or social media posts, without requiring a predefined schema or complex joins. MongoDB also supports cloud-based deployment, scalability, and high availability. The other options are either relational databases that require a fixed schema and structure for data, or specialized databases that are designed for specific purposes, such as graph databases for storing and analyzing network data. Reference: CompTIA DataSys+ Course Outline, Domain 1.0 Database Fundamentals, Objective 1.1 Given a scenario, identify and apply database structure types.
NEW QUESTION # 111
(Before installing a new database instance for an organization, a DBA needs to verify the amount of space, the hardware, and the network resources. Which of the following best describes this process?)
Answer: A
Explanation:
The correct answer is C. Checking for database prerequisites. According to CompTIA DataSys+ objectives, verifying prerequisites is a critical preparatory step before installing a new database instance.
Database prerequisites refer to the minimum and recommended requirements that must be met to ensure a successful installation and stable operation of the database system.
This process typically includes validating disk space availability, CPU capacity, memory (RAM), and network resources, as well as confirming operating system compatibility, required libraries, kernel parameters, and supporting services. DataSys+ emphasizes that failure to meet prerequisites can lead to installation errors, poor performance, instability, or security vulnerabilities after deployment. Therefore, DBAs are expected to thoroughly assess the environment before proceeding with installation.
Option A, performing patch management, refers to applying updates and fixes to existing systems to address bugs or security issues. This occurs after software is installed and operational, not before a new database instance is deployed. Option B, upgrading the database instance, involves moving from one version of a database to another and assumes an existing installation is already in place. Option D, provisioning the configuration, focuses on allocating and configuring resources (such as creating instances, users, or storage structures) after prerequisites have been validated.
CompTIA DataSys+ clearly separates environment validation from deployment and configuration activities. Checking prerequisites is a risk-reduction step that ensures the infrastructure can support the database workload and performance expectations from the start. It also supports capacity planning, compliance, and long-term maintainability.
Therefore, the process of verifying space, hardware, and network resources before installing a database instance is best described as checking for database prerequisites, making option C the correct and fully verified answer.
NEW QUESTION # 112
Which of the following are the best resources for monitoring potential server issues? (Choose two.)
Answer: E,F
Explanation:
The two resources that are best for monitoring potential server issues are CPU usage and memory usage. CPU usage is the percentage of time that the processor (CPU) of the server is busy executing instructions or processes. CPU usage indicates how much workload the server can handle and how fast it can process requests. High CPU usage may affect the performance or availability of the server and cause delays or errors. Memory usage is the amount of physical memory (RAM) or virtual memory (swap space) that the server uses to store data or run applications. Memory usage indicates how much space the server has to store temporary or intermediate data or results. High memory usage may affect the performance or availability of the server and cause swapping or paging. The other options are either not relevant or not direct indicators of server health. For example, user connections are the number of users who are connected to a database server at any given time; firewall usage is the amount of data that passes through a firewall device or software; index usage is the frequency or efficiency of using indexes on tables to speed up queries; query execution is the process of running SQL statements on a database server.
