NEW QUESTION # 46
A database administrator is concerned about transactions in case the system fails. Which of the following properties addresses this concern?
Answer: B
Explanation:
The property that addresses this concern is durability. Durability is one of the four properties (ACID) that ensure reliable transactions in a database system. Durability means that once a transaction has been committed, its effects are permanent and will not be lost in case of system failure, power outage, crash, etc. Durability can be achieved by using techniques such as write-ahead logging, checkpoints, backup and recovery, etc. The other options are either not related or not specific to this concern. For example, isolation means that concurrent transactions do not interfere with each other and produce consistent results; atomicity means that a transaction is either executed as a whole or not at all; consistency means that a transaction preserves the validity and integrity of the data. Reference: CompTIA DataSys+ Course Outline, Domain 1.0 Database Fundamentals, Objective 1.3 Given a scenario, identify common database issues.
NEW QUESTION # 47
A business analyst is using a client table and an invoice table to create a database view that shows clients who have not made purchases yet. Which of the following joins is most appropriate for the analyst to use to create this database view?
Answer: A
Explanation:
The join that is most appropriate for the analyst to use to create this database view is option D. This join uses the LEFT JOIN clause to combine the client table and the invoice table based on the matching values in the Key column. The WHERE clause filters out the rows where the Invoice.Key column is not null, meaning that the client has made a purchase. The result is a view that shows only the clients who have not made any purchases yet. The other options either do not produce the desired result or have syntax errors. For example, option A would show only the clients who have made purchases, option B would show only the invoices that do not have a matching client, and option C would show all the clients regardless of their purchase status. References: CompTIA DataSys+ Course Outline, Domain 1.0 Database Fundamentals, Objective 1.2 Given a scenario, execute database tasks using scripting and programming languages.
NEW QUESTION # 48
A DBA left the company, and the DBA's account was removed from the system. Soon after, scheduled jobs began failing.
Which of the following would have most likely prevented this issue?
Answer: B
Explanation:
The most likely way to prevent this issue is to use service accounts. Service accounts are special accounts that are used by applications or services to perform tasks or run jobs on behalf of users.
Service accounts have limited permissions and access rights that are tailored to their specific functions. By using service accounts, the DBA can ensure that scheduled jobs can run independently of individual user accounts, and avoid failures due to account removal or changes.
The other options are either not related or not effective for this issue. For example, load balancing is a technique that distributes the workload across multiple servers or resources to improve performance and availability; business continuity plan is a plan that outlines how an organization will continue its operations in the event of a disaster or disruption; assigning a data steward is a process that designates a person who is responsible for ensuring the quality and governance of data.
NEW QUESTION # 49
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?
Answer: C
Explanation:
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.
NEW QUESTION # 50
(A database administrator wants to create a database that does not have a predefined schema. Which of the following tools should the administrator use to create this type of database? Select two.)
Answer: C,F
Explanation:
The correct answers are E. MongoDB and F. Cosmos. CompTIA DataSys+ clearly differentiates between relational databases, which require predefined schemas, and non-relational (NoSQL) databases, which support flexible or schema-less data models. A schema-less database allows data to be stored without enforcing a fixed table structure, making it ideal for rapidly changing data requirements, unstructured data, or applications with evolving schemas.
MongoDB is a document-oriented NoSQL database that stores data in flexible, JSON-like documents. Each document in a MongoDB collection can have a different structure, allowing developers to add or remove fields without modifying a predefined schema. DataSys+ highlights document stores like MongoDB as well- suited for modern applications that require agility, scalability, and the ability to handle semi-structured or unstructured data.
Cosmos (commonly referring to Azure Cosmos DB) is a globally distributed NoSQL database service that supports multiple data models, including core (SQL) API, MongoDB API, and other non-relational models. It is designed for high availability, horizontal scalability, and schema flexibility. DataSys+ includes cloud-based NoSQL platforms such as Cosmos as examples of databases that do not enforce rigid schemas.
Options A, B, C, and D-PostgreSQL, MariaDB, MySQL, and SQL Server-are all relational database management systems (RDBMS). These systems require predefined schemas with fixed table definitions, column data types, and constraints before data can be stored. While some relational systems support limited JSON storage, they are still fundamentally schema-based and do not meet the requirement described in the question.
CompTIA DataSys+ emphasizes selecting database technologies based on data structure and application needs. When schema flexibility is required, NoSQL solutions are preferred. Therefore, the tools best suited for creating a database without a predefined schema are MongoDB and Cosmos, making options E and F the correct and fully verified answers.
