Which of the following is an SLA?

A document describing the impact of a nonfunctional server describes a Business Impact Analysis (BIA), which is part of business continuity planning, not an SLA.

An SLA is a legally binding contract that defines the agreed-upon level of service between a service provider and its customer, including specific, measurable terms such as device replacement windows, response times, and availability percentages. Device replacement timeframes are a classic SLA provision, making this the correct definition.

A document outlining correct equipment disposal requirements is an environmental compliance or asset disposal policy, not a service level agreement.

A statement of compliance with local laws and regulations is a regulatory compliance declaration, which is distinct from the performance commitments defined in an SLA.
