質問 # 115
Which of the following is part of logical database infrastructure security?
正解：B
解説：
The option that is part of logical database infrastructure security is perimeter network. Perimeter network, also known as DMZ (Demilitarized Zone), is a network segment that lies between an internal network and an external network, such as the internet. Perimeter network provides an additional layer of security for the internal network by isolating and protecting the servers or services that are exposed to the external network, such as web servers, email servers, database servers, etc. Perimeter network also helps prevent unauthorized access or attacks from the external network to the internal network by using firewalls, routers, proxies, etc. The other options are either part of physical database infrastructure security or not related to database infrastructure security at all. For example, surveillance is a method of monitoring and recording physical activities or events in a location or resource; biometric access is a device that uses biological characteristics to control access to a physical location or resource; cooling system is a device or system that regulates the temperature and humidity of a location or resource.

(An analyst in the United States configured a database server so it could be accessed remotely by users in Brazil and Canada. Users in Brazil can connect to the server, but users in Canada cannot connect to the server.
Which of the following is the reason for the issue?)
正解：C
解説：
The correct answer is B. The rule set was configured to allow specific IP addresses. CompTIA DataSys+ materials emphasize the importance of network security controls, particularly firewall rules and access control lists (ACLs), in regulating remote database access. In this scenario, the database server is reachable by users in Brazil but not by users in Canada, which strongly indicates that access is being selectively permitted rather than globally blocked.
Firewall rule sets are often configured using IP-based allowlists, where only approved IP addresses or IP ranges are permitted to establish a connection. If the analyst allowed the IP address range associated with Brazil but did not include the IP range used by Canadian users, connections from Canada would fail while Brazilian users would still have access. This behavior aligns precisely with selective rule-based access control, a common best practice highlighted in DataSys+ for reducing attack surfaces.
Option A is incorrect because if the perimeter network were rejecting remote connections entirely, users in Brazil would also be unable to connect. Option C is incorrect for the same reason: a firewall rule denying all connections would block access from all locations, not just Canada. Option D, server port security being disabled, would typically prevent all inbound connections to the database service, again affecting all users regardless of geography.
CompTIA DataSys+ stresses that troubleshooting connectivity issues requires identifying whether failures are global or location-specific. Location-specific failures are most commonly caused by misconfigured firewall rules, IP filtering, or regional access restrictions. In database environments that support remote access, DBAs must ensure that firewall rules are consistently applied to all authorized networks.
Therefore, the most accurate and verified explanation is that the rule set was configured to allow specific IP addresses, and the Canadian users' IP range was not included. This makes option B the correct answer.
質問 # 117
An on-premises application server connects to a database in the cloud. Which of the following must be considered to ensure data integrity during transmission?
正解：C
解説：
The factor that must be considered to ensure data integrity during transmission is encryption. Encryption is a process that transforms data into an unreadable or scrambled form using an algorithm and a key. Encryption helps protect data integrity during transmission by preventing unauthorized access or modification of data by third parties, such as hackers, eavesdroppers, or interceptors. Encryption also helps verify the identity and authenticity of the source and destination of the data using digital signatures or certificates. The other options are either not related or not sufficient for this purpose. For example, bandwidth is the amount of data that can be transmitted over a network in a given time; redundancy is the duplication of data or components to provide backup or alternative sources in case of failure; masking is a technique that replaces sensitive data with fictitious but realistic data to protect its confidentiality or compliance. References: CompTIA DataSys+ Course Outline, Domain 4.0 Data and Database Security, Objective 4.2 Given a scenario, implement security controls for databases.
質問 # 118
Which of the following best describes a collection of data that shares the same properties or attributes?
正解：A
解説：
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. Reference: CompTIA DataSys+ Course Outline, Domain 1.0 Database Fundamentals, Objective 1.1 Given a scenario, identify common database types.
質問 # 119
A database administrator needs a tool to document and explain the relationships between data in an organization's database. Which of the following is the best tool to accomplish this task?
正解：C
解説：
The best tool for the database administrator to document and explain the relationships between data in an organization's database is a UML editor. A UML editor is a software application that allows users to create, edit, and visualize diagrams using the Unified Modeling Language (UML). UML is a standard language for modeling software systems and their components, such as classes, objects, relationships, behaviors, etc. UML can also be used to document and explain the relationships between data in an organization's database by creating entity relationship diagrams (ERDs), which are graphical representations of the entities (tables), attributes (columns), and relationships (constraints) in a database. A UML editor can help the administrator to document and explain the relationships between data by providing features such as drag-and-drop, templates, symbols, validation, etc. The other options are either not suitable or not optimal for this task. For example, a text editor is a software application that allows users to create and edit plain text files; a word processor is a software application that allows users to create and edit text documents; an SQL query is a statement that performs an operation on a database using Structured Query Language (SQL). References: CompTIA DataSys+ Course Outline, Domain 2.0 Database Deployment, Objective 2.2 Given a scenario, create database objects using scripting and programming languages.
