A company recently acquired a number of sites and no documentation was provided. A network administrator needs to identify and document all of the digital assets in use. Which of the following is…

Availability monitoring tracks whether systems are operational but doesn't primarily identify all unique digital assets or their configurations in an unknown environment.

Packet capture is used for deep analysis of specific network traffic flows to diagnose problems, not for broadly identifying all digital assets across an entire network.

Physical inventory involves manually checking hardware, which is time-consuming, prone to human error, and might miss virtual assets or devices located remotely, making it less efficient and comprehensive than network discovery for digital assets.

Network discovery involves using specialized tools and techniques to automatically scan a network, identify active devices, their IP addresses, open ports, and sometimes even their operating systems and running services. This systematic approach provides the most comprehensive way to quickly identify and document all digital assets within an unknown infrastructure.
