Question

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 the best method for the administrator to use?

Options

  • AAvailability monitoring
  • BPacket capture
  • CPhysical inventory
  • DNetwork discovery

Explanation

Network discovery is the most effective method for identifying and documenting all active digital assets within an undocumented network environment.

Common mistakes.

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

Concept tested. Network discovery for asset inventory
