What is an example of a dedicated server?

A dedicated server is one that is fully allocated to a single purpose or service, rather than being shared among multiple users or tasks. This ensures that resources (such as CPU, RAM, and storage) are solely used for that one application or function, which can lead to improved performance, security, and reliability.

In this context, a database server is a prime example of a dedicated server. It is specifically designed to manage and serve database requests, handle data storage, and ensure that database operations are optimized for speed and efficiency. Since it is dedicated to running database management software and processing queries, it provides consistent performance characteristics that are crucial for applications relying on data retrieval and storage.

The other options describe various types of servers or configurations, but they do not fit the definition of a dedicated server as closely. A virtual switch server refers to network functions, a clustered server involves multiple servers working together to enhance availability or performance, and a secure shell server focuses on secure remote command execution and does not indicate a specific application-focused environment like a database server does.
