CompTIA DataSys+ Certification Exam Sample Questions (Q113-Q118):

NEW QUESTION # 113
A company needs to prepare a document that establishes the responsibilities, metrics, penalties, and other generalities that a provider would have to fulfill for customers to use its platforms.
Which of the following documents meets these requirements?

Answer: D

Explanation:
The document that meets these requirements is an SLA. An SLA, or Service Level Agreement, is a contract between a service provider and a customer that defines the scope, quality, and terms of the service delivery. An SLA typically includes the responsibilities, metrics, penalties, and other generalities that a provider would have to fulfill for customers to use its platforms. An SLA also establishes the expectations and obligations of both parties, as well as the methods for measuring and monitoring the service performance. The other options are either different types of documents or not related to service delivery. For example, a DOU, or Data Use Agreement, is a document that governs the sharing and use of data between parties; an MOU, or Memorandum of Understanding, is a document that expresses a mutual agreement or intention between parties; a SOW, or Statement of Work, is a document that describes the specific tasks and deliverables of a project or contract. Reference: CompTIA DataSys+ Course Outline, Domain 2.0 Database Deployment, Objective 2.4 Given a scenario, implement service level agreements.


NEW QUESTION # 114
During a routine audit, a database administrator discovers that the department manager's birthday is next week. The database administrator decides to plan a birthday party for the manager. Which of the following guidelines would the administrator violate by planning the party?

Answer: C


NEW QUESTION # 115
Which of the following describes a scenario in which a database administrator would use a relational database rather than a non-relational database?

Answer: D

Explanation:
A scenario in which a database administrator would use a relational database rather than a non-relational database is when an organization wants to maintain consistency among the data in the database. A relational database is a type of database that organizes data into tables with predefined columns and rows, and enforces rules and constraints to ensure data integrity and accuracy. A relational database also supports transactions, which are sets of operations that must be executed as a whole or not at all, to prevent data corruption or inconsistency. The other options are either not exclusive to relational databases or not relevant to the choice of database type. For example, data encryption can be applied to both relational and non-relational databases, processing complex data sets may require specialized tools or techniques that are not dependent on the database type, and storing a large number of videos, photos, and documents may be better suited for a non-relational database that can handle unstructured or semi-structured 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 # 116
Which of the following is used to hide data in a database so the data can only be read by a user who has a key?

Answer: C

Explanation:
The option that is used to hide data in a database so the data can only be read by a user who has a key is data encryption. Data encryption is a process that transforms data into an unreadable or scrambled form using an algorithm and a key. Data encryption helps protect data from unauthorized access or modification by third parties, such as hackers, eavesdroppers, or interceptors. Data encryption also helps verify the identity and authenticity of the source and destination of the data using digital signatures or certificates. Data encryption can be applied to data at rest (stored in a database) or data in transit (transmitted over a network). To read encrypted data, a user needs to have the corresponding key to decrypt or restore the data to its original form. The other options are either different concepts or not related to hiding data at all.
For example, data security is a broad term that encompasses various methods and techniques to protect data from threats or risks; data masking is a technique that replaces sensitive data with fictitious but realistic data to protect its confidentiality or compliance; data protection is a term that refers to the legal or ethical obligations to safeguard personal or sensitive data from misuse or harm.


NEW QUESTION # 117
A programmer wants to configure a database to only allow read or write access when requests are coming from specific IP addresses. Which of the following can be used to configure IP addresses to allow access to the database?

Answer: A

Explanation:
The best option to configure IP addresses to allow access to the database is a firewall. A firewall is a network device or software that controls the incoming and outgoing traffic based on a set of rules or policies. A firewall can be used to filter the traffic by IP addresses, ports, protocols, or other criteria, and allow or deny access to the database accordingly. The other options are either not relevant or not sufficient for this task. For example, a static IP address is an IP address that does not change over time, but it does not determine the access to the database; a dynamic IP address is an IP address that changes periodically, but it does not control the traffic to the database; an IDNS is an Internet Domain Name System, which translates domain names into IP addresses, but it does not regulate the access to the database. References: CompTIA DataSys+ Course Outline, Domain 4.0 Data and Database Security, Objective 4.2 Given a scenario, implement security controls for databases.
