Question 4

Service-level agreement outlines the configuration, maintenance, and security roles between a cloud service provider and the customer.

A service-level agreement (SLA) is a formal document that defines the expected level of service between a service provider and a customer, detailing the configuration, maintenance, and security responsibilities.

A) Service-level agreement

An SLA explicitly outlines the duties and expectations of both the cloud service provider and the customer, including aspects of configuration, maintenance, and security. It serves as a key reference point for both parties in managing their responsibilities and ensuring compliance with agreed standards.

B) Responsibility matrix

While a responsibility matrix can clarify roles and responsibilities, it typically does not encompass the comprehensive legal and service expectations found in an SLA. It may serve as a supplementary document but lacks the formal agreement and detailed service commitments inherent in an SLA.

C) Memorandum of understanding

A memorandum of understanding (MOU) generally outlines a mutual agreement between parties but is less formal than an SLA and does not typically detail specific operational roles related to configuration, maintenance, and security in a cloud context. An MOU may express intent but lacks the binding service commitments found in an SLA.

D) Non-disclosure agreement

A non-disclosure agreement (NDA) is focused on confidentiality and the protection of sensitive information between the provider and the customer. It does not address the operational aspects of configuration, maintenance, or security roles, thus making it irrelevant in the context of outlining these responsibilities.

Conclusion

The service-level agreement is the definitive document that outlines the configuration, maintenance, and security roles between a cloud service provider and the customer. Other options, such as the responsibility matrix, memorandum of understanding, and non-disclosure agreement, do not provide the comprehensive framework or binding commitments necessary for defining these specific operational roles. Therefore, the SLA is essential for ensuring clarity and accountability in the service relationship.
