The correct option is System Administrator.

A System Administrator is responsible for installing configuring and maintaining servers and operating systems and for managing host level settings. They keep inventories and configuration records and they coordinate patching and vulnerability remediation so they can provide detailed technical information about server configurations network settings and known vulnerabilities during a cybersecurity review.

Legal Counsel focuses on legal risk compliance contracts and policy advice and they do not typically handle low level technical server configurations or maintain vulnerability inventories so they are not the right source for detailed technical data.

Cloud Network Engineer specialises in cloud networking design connectivity and routing and they may provide network specific details. They usually do not own host configuration management or the full application vulnerability inventory so they are not the typical provider of comprehensive server vulnerability information.

Site Reliability Engineer concentrates on service reliability automation and operational tooling and they may supply runbook and operational metrics. They often work with the system administration function but they are not always the owner of server configuration records or vulnerability tracking so they are not the default answer.
