Observe the network diagram. Which of the following hosts is intended to keep ICS process data in a database?


Suggested Answer: A Vote an answer
The host with IP 10.10.4.11 in the network diagram is labeled as the Historian Server. ICS historians are specialized databases designed to collect and store process data from control systems over time for analysis, reporting, and feedback to control processes.
10.10.31.217 is a Microsoft Access Workstation (not a database server).
10.10.4.123 represents NTP servers (time servers), not data storage.
10.10.4.239 is an Engineering Workstation.
10.103.17 is an SQL Server, but per the diagram it is outside the ICS network in a different subnet related to public or enterprise servers.
Thus, 10.10.4.11 (A) is the host intended to store ICS process data.
