Failover is a technique that ensures high availability of databases by switching to a backup or standby server in case of a primary server failure. Failover can be automatic or manual, depending on the configuration. Failover can prevent data loss and downtime for critical applications that rely on databases. References: The Official CompTIA IT Fundamentals (ITF+) Student Guide (Exam FC0-U61), Chapter 5, Section 5.3, Page 222.

Fiber optic is a type of Internet service connection that uses thin strands of glass or plastic to transmit data using light signals. Fiber optic offers high bandwidth, speed, and reliability compared to other types of Internet service connections. T1 line, satellite, and DSL are not types of Internet service connections that offer significant bandwidth for remote users. References: CompTIA IT Fundamentals+ Study Guide: Exam FC0-U61, Second Edition, Chapter 6: Infrastructure Concepts, page 229.

A database is a collection of data that is organized so that it can be easily accessed, managed, and updated. A database can store different types of data, such as text, audio, video, images, and documents, in a structured way that allows for efficient searching, sorting, filtering, and querying. A database can also enforce rules and constraints on the data to ensure its validity and consistency. A database is best suited to meet the need of a music studio that wants to store artist data as text, demos as MP3 files, and sheet music as PDF files in an organized and easily searchable format, because it can handle the variety, volume, and complexity of the data, and provide fast and accurate retrieval and manipulation of the data. References:
