NEW QUESTION # 99
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: B
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. Reference: CompTIA DataSys+ Course Outline, Domain 4.0 Data and Database Security, Objective 4.2 Given a scenario, implement security controls for databases.
NEW QUESTION # 100
Which of the following can be used to protect physical database appliances from damage in a server room? (Choose two.)
Answer: A,D
Explanation:
The two options that can be used to protect physical database appliances from damage in a server room are fire suppression systems and cooling systems. Fire suppression systems are systems that detect and extinguish fires in a server room using water, gas, foam, or other agents.
Fire suppression systems help prevent damage to physical database appliances caused by fire hazards such as overheating, electrical faults, or flammable materials. Cooling systems are systems that regulate the temperature and humidity in a server room using fans, air conditioners, chillers, or other devices. Cooling systems help prevent damage to physical database appliances caused by excessive heat or moisture that may affect their performance or lifespan. The other options are either not related or not effective for this purpose. For example, biometric access systems, camera systems, and key card systems are systems that control the access to a server room using fingerprints, facial recognition, video surveillance, or magnetic cards; these systems help prevent unauthorized entry or theft of physical database appliances, but not damage caused by environmental factors; database control systems are systems that manage the functionality and security of databases using software tools or commands; these systems help protect logical database appliances from errors or attacks, but not physical damage caused by environmental factors.
NEW QUESTION # 101
Which of the following database instances are created by default when SQL Server is installed? (Choose two.)
Answer: A,B
Explanation:
The two database instances that are created by default when SQL Server is installed are master and model.
Master is a system database that contains the information and settings of the SQL Server instance, such as the configuration, logins, endpoints, databases, etc. Master is essential for the operation and management of the SQL Server instance, and it should be backed up regularly. Model is a system database that serves as a template for creating new user databases. Model contains the default settings and objects, such as tables, views, procedures, etc., that will be inherited by the new user databases. Model can be modified to customize the new user databases according to specific needs or preferences. The other options are either not database instances or not created by default when SQL Server is installed. For example, root is not a database instance, but a term that refers to the highest level of access or privilege in a system; log is not a database instance, but a file that records the changes made by transactions on a database; view is not a database instance, but an object that represents a subset or a combination of data from one or more tables; index is not a database instance, but a data structure that stores the values of one or more columns of a table in a sorted order. References: CompTIA DataSys+ Course Outline, Domain 2.0 Database Deployment, Objective 2.3 Given a scenario, update database systems.
NEW QUESTION # 102
A database administrator realizes that certain data was not captured correctly when it was imported. Which of the following commands should the administrator use to fix the issue?
Answer: C
Explanation:
The UPDATE command allows the administrator to modify existing records in a table to correct data that was not captured correctly during import.
NEW QUESTION # 103
Which of the following database structures is a type of NoSQL database?
Answer: B
Explanation:
The database structure that is a type of NoSQL database is key-value stores. Key-value stores are databases that store and manage data as pairs of keys and values. Keys are unique identifiers that locate data in the database; values are arbitrary data that can be any type or format. Key-value stores do not use any schema or structure to organize data, but rather use hash tables or indexes to enable fast and simple access to data based on keys. Key-value stores are suitable for storing large amounts of simple or unstructured data that do not require complex queries or relationships. The other options are either different types of databases or not related to database structures at all. For example, hierarchical databases are databases that store and manage data as nodes in a tree-like structure; cloud databases are databases that are hosted and accessed over the internet using cloud computing services; object-oriented databases are databases that store and manage data as objects that have attributes and methods. References: CompTIA DataSys+ Course Outline, Domain 1.0 Database Fundamentals, Objective 1.1 Given a scenario, identify common database types.
