Answer :
The company is using a network server to monitor the status of network interfaces and devices. Network servers manage network resources and communication while providing vital status reports and alerts. This function differs from the roles of web, database, and file servers. Hence, option 4 is the correct answer.
A company that uses an app to monitor and keep track of the status of network interfaces and devices, specifically noting downtimes and resets, is likely using a network server. A network server plays a crucial role in managing network resources, ensuring that devices within a network can communicate effectively, and overseeing the operations such as those that report on interface statuses and alerts on device power cycles. This is distinct from a web server, which primarily deals with delivering web content, or a database server, which focuses on storing and retrieving data, and from a file server, which is dedicated to storing and managing files within a network.
Understanding the elements that make up a typical web server can be useful; however, in this context, the primary components involved are the hardware, operating system, and the network monitoring software that is likely to be leveraging protocols like Simple Network Management Protocol (SNMP) or similar means to keep tabs on network devices' status. The infrastructure's security must be robust to prevent unauthorized access and protect against potential security breaches. Hence, option 4 is the correct answer.
