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

Incorrect because activity 4 - implementing all standard changes - is not a service desk responsibility and belongs to the change management process.

Activities 1, 2, and 3 are all core service desk responsibilities defined in ITIL: logging details of incidents and service requests, providing first-line investigation and diagnosis, and restoring service where possible. Activity 4 is excluded because implementing all standard changes falls under the change management process, not the service desk function.

This excludes logging (1) and service restoration (3), both of which are explicitly defined core service desk activities in ITIL.

This excludes logging (1) and first-line investigation and diagnosis (2), which are primary service desk activities, and incorrectly includes implementing all standard changes.
