The purpose of the network device implemented by the network administrator in this scenario is to improve the performance and availability of the database server by distributing the workload across multiple servers. This is known as load balancing.
Load balancing is a technique that allows multiple servers to work together to provide a higher level of availability and scalability. When a user requests access to the web-based application, the network device distributes the request to one of several available database servers based on predefined criteria such as server capacity, response time, or geographical location.
Load balancing helps prevent overloading on any one server, improves response time, and provides fault tolerance in the event that one of the servers fails. Additionally, load balancing can help reduce downtime during maintenance windows by allowing one or more servers to be taken offline without impacting the overall performance of the application.
Content filtering and network analysis, port sniffing and protocol analysis, and clustering and NIC teaming are all network-related functions that are different from load balancing and not applicable to this scenario.
Content filtering and network analysis are used to monitor and control network traffic for security purposes. Port sniffing and protocol analysis are used to diagnose network issues and identify performance bottlenecks. Clustering and NIC teaming are used to provide redundancy and high availability for servers, but they are not related to load balancing.
