Which of the following activities are performed by a service desk? 1. Logging details of incidents and service requests 2. Providing first-line investigation and diagnosis 3. Restoring service 4. Impl

Not all four activities are performed by the service desk - implementing all standard changes is not a defined service desk responsibility in ITIL.

The service desk is responsible for logging all incident and service request details (activity 1), performing first-line investigation and diagnosis (activity 2), and working to restore service to users (activity 3) as core functions. Activity 4 is incorrect because while the service desk may handle some very simple standard changes, implementing ALL standard changes falls to change and release management processes, not exclusively the service desk.

This combination is incorrect because it excludes logging and service restoration, which are primary service desk duties, and incorrectly includes implementing all standard changes.

This combination omits logging and first-line investigation, which are two of the most fundamental service desk activities, and incorrectly includes implementing all standard changes.
