示例题目
Worked example考察的是推理，而不是措辞。
An analyst sees repeated outbound connections to a newly registered domain immediately after a PowerShell process starts. What should be investigated first?
完整访问权限包含每道已作答题目后的清晰解析，包括为什么其他选项不够合适。
Why this is the best answer
The combination of a script process, a recently registered destination, and repeated outbound traffic makes possible command-and-control activity a reasonable investigation hypothesis. Correlate the process tree, command line, destination, and timing. Neither PowerShell use nor a new domain alone proves compromise.
Why the other options fit less well
The scenario gives no evidence of a vulnerability scan, DNS replication, or certificate maintenance. Validate the suspicious sequence against known administrative activity before declaring an incident.
