Which of the following is considered a self-service technology?

The correct choice is Automated Remediation technologies because they empower users to resolve issues independently without needing direct assistance from support personnel. This type of self-service technology allows users to execute pre-defined actions or scripts to fix common problems on their own, enhancing efficiency and reducing downtime.

In contrast, Remote Administration tools typically require technician involvement to manage and troubleshoot systems remotely, thus not qualifying as a self-service option. Knowledge Management Systems provide resources and information that can assist users in finding solutions, but they rely on the user's ability to utilize this information effectively and do not take action on behalf of the user. Mobile Device Management focuses on overseeing mobile devices in the enterprise and involves administrative roles in managing these devices rather than enabling self-sufficiency for users.
