A. UNION AND

NEW QUESTION # 14
Which of the following can be used to protect physical database appliances from damage in a server room?
(Choose two.)

A. Biometric access systems
B. Camera systems
C. Database control systems
D. Fire suppression systems
E. Key card systems
F. Cooling systems

Answer: D,F

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 # 15
Which of the following describes a scenario in which a database administrator would use a relational database rather than a non-relational database?

A. An organization requires data encryption.
B. An organization wants to maintain consistency among the data in the database.
C. An organization wants to store a large number of videos, photos, and documents.
D. An organization wants to process complex data sets.

Answer: B

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 # 16
An analyst shared a database directly from a workstation. A week later, users could not access the database, but could access other shared resources. Which of the following is the most likely reason the shared database is unavailable?

A. The DNS changed the workstation's name.
B. The DNS permissions changed.
C. The IP addresses for the sharing workstation changed.
D. The IP addresses for the users' workstations changed.

Answer: C

Explanation:
If the workstation sharing the database obtains a new IP address (e.g., via DHCP), other users relying on the old IP will no longer reach it, causing the shared database to become unavailable.
