Which of the following is an example of automated remediation functionality?

Automated remediation functionality refers to systems or processes that automatically resolve issues without the need for manual intervention. In the scenario presented, restoring services after a virus is a clear example of automated remediation because it involves the use of technology to identify the problem caused by the virus and take corrective actions, such as restoring systems to a healthy state or removing the virus automatically. This minimizes downtime and ensures that systems can operate normally with little to no manual oversight.

The other options do not align with the concept of automated remediation. Personalized customer support involves human interaction and is tailored to individual needs, which doesn't fit the definition of automation in problem resolution. Writing user manuals is a one-time task that provides documentation, but it does not actively resolve issues as they occur. Conducting customer satisfaction surveys collects feedback but does not address or rectify any issues users may experience. Thus, the focus is on how the correct option embodies the essence of automatic problem-solving.
