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

Activity 4 states the service desk implements all standard changes, which is incorrect because standard changes are the responsibility of specialist technical staff, not the service desk.

The ITIL service desk is accountable for logging all incidents and service requests (1), conducting first-line investigation and diagnosis (2), and restoring service where possible through workarounds or basic fixes (3). These three activities are core service desk responsibilities. Implementing all standard changes (4) is not a service desk function - standard changes are typically executed by specialist technical teams, and only very simple ones may occasionally be handled at the service desk level.

This option includes activity 4 (implementing all standard changes), which is not a service desk responsibility, and omits activity 1 (logging), which is a fundamental service desk function.

This option omits activities 1 and 2, which are among the most essential service desk responsibilities, and incorrectly includes activity 4 which is not a service desk role.
