Company XYZ wants to use the FCAPS ISO standard for network management design. The focus of the design should be to minimize network outages by employing a set of procedures and activities to detect…

Fault Management in the FCAPS model specifically covers the detection, isolation, and correction of abnormal network conditions. It encompasses proactive and reactive procedures - such as alarm correlation and root-cause analysis - to restore service and prevent recurrence. This directly matches the requirement to minimize outages through detection, isolation, and corrective actions.

Accounting management tracks resource usage and billing data, not fault detection or isolation.

Security management controls access policies, authentication, and authorization to protect network resources.

Performance management monitors throughput, latency, and utilization to optimize network efficiency, not to isolate and correct faults.
