ITIL V4: Which statement about a change authority is correct?

Which statement about a change authority is correct?

OPTIONS

• A single change authority should be assigned to authorize all types of change and change models
• A change authority should be assigned for each type of change and change model
• Normal changes are pre-authorized and do not need a change authority
• Emergency changes can be implemented without authorization from a change authority

Answer:

A change authority should be assigned for each type of change and change model

Explanation:

It is essential that the correct change authority is assigned to each type of change to ensure that change enablement is both efficient and effective. For normal changes, change models based on the type of change determine the roles for assessment and authorization.
