将来的に IT システムが要求される可用性サービス レベルを満たすことができなくなるリスクに関する最も優れた洞察を提供する主要リスク指標 (KRI) は次のどれですか。
正解:D
The percentage of IT systems routinely running at peak utilization serves as a leading indicator of potential future availability issues. Systems operating at or near full capacity are more susceptible to performance degradation or outages, which can impede their ability to meet service level agreements (SLAs). Monitoring this KRI allows organizations to proactively address capacity constraints before they impact system availability.
