Which of the following is not appropriate to include in an SLA?

The statement about personnel who are responsible and authorized to declare an emergency and transition the service to contingency operation status is, in fact, an essential element that should be included in a Service Level Agreement (SLA). Such details help define clear roles and responsibilities during critical situations, ensuring that both parties understand who makes decisions and initiates the transition to contingency operations. This can significantly enhance communication and response times during emergencies.

In contrast, while the other elements listed may also be important in a broader operational context, they are typically more related to operational metrics and limits rather than disaster recovery roles. For instance, restrictions on the number of user accounts, the timing for migration to contingency operations, and data transmission limits are all well-defined operational parameters that assess service performance and capacity. However, the specifics of emergency declaration and the associated personnel roles are critical for ensuring effective governance during unexpected events, making this option inappropriate as a non-inclusion in an SLA.
