Bluetooth is the wireless technology commonly identified in IT fundamentals as supporting short-range communication up to around 300 feet in higher-power implementations. Bluetooth is designed for personal area networking, connecting devices such as headphones, keyboards, speakers, and smartphones with low power consumption and easy pairing. Different Bluetooth classes exist: some provide only a few meters of range, while higher-power versions can extend to roughly 100 meters, which is close to 300 feet, under good conditions. Wi-Fi typically supports larger local-area coverage and is used to connect devices to local networks and the internet. A wide area network is not a wireless technology standard; it is a type of network spanning large geographic areas. Near field communication is designed for extremely short distances, usually a few centimeters, and is used for contactless payments and quick device taps. Since the question asks for a wireless technology specifically accommodating distances up to 300 feet, Bluetooth best matches that description.

The central processing unit, or CPU, is the primary component responsible for performing operations on data for all applications running on a computer. In Information Technology fundamentals, the CPU is often called the brain of the computer because it executes program instructions, performs arithmetic and logical operations, and controls the overall flow of processing. When an application runs, its instructions are fetched from memory, decoded, and executed by the CPU using key internal units such as the control unit and the arithmetic logic unit. RAM supports the CPU by holding active programs and data temporarily for fast access, but RAM does not perform processing itself. ROM stores firmware instructions such as startup routines, but it is not used for general application processing. A GPU is specialized for highly parallel tasks like graphics rendering and certain compute workloads, but it is not the main processor for all applications. Therefore, the component that performs operations on data from all applications is the CPU.

Hot storage, often discussed alongside hot sites in disaster recovery, refers to storage and recovery capabilities that are ready for rapid use with minimal delay. In IT disaster recovery terms, hot solutions emphasize high availability and quick restoration, which generally requires modern, high-performance, always-ready equipment and frequent data synchronization. Because hot storage is intended to support fast recovery time objectives, it is typically implemented using advanced storage systems, real-time replication, and automated failover technologies. The other options describe characteristics more aligned with colder approaches. Infrequent access and slow restoration are associated with cold storage or cold sites, where backups may be archived and recovery takes longer. Using lower-performance equipment also fits cold or warm recovery strategies, where cost savings are prioritized over immediate availability. Hot storage solutions are designed to minimize downtime and data loss, and this generally implies up-to-date, capable infrastructure rather than reduced performance. Therefore, among the options provided, the best characteristic of hot storage is that it typically uses innovative equipment.

The core responsibility of a database administrator (DBA) centers around managing and optimizing Database Management Systems (DBMS). This includes:

•Installation and Configuration: Setting up new database instances, applying relevant configurations, and ensuring they align with the organization's needs.

•Maintenance: Performing regular backups, security updates, and patch management to keep the databases secure and healthy.

•Performance Analysis: Monitoring database performance, identifying bottlenecks, and implementing optimizations to ensure efficient data retrieval and operations.

•Troubleshooting: Proactively addressing database errors, resolving operational issues, and ensuring data integrity.
