Which of the following outlines the configuration, maintenance, and security roles between a cloud service provider and the customer?

A responsibility matrix, often known as a RACI matrix, identifies specific tasks, roles, and responsibilities within a project but does not typically encompass comprehensive details about configuration, maintenance, and security roles between a cloud service provider and the customer. Instead, it focuses on clarifying who is responsible for what in a specific context or project.

A memorandum of understanding (MOU) is a document that outlines an agreement between parties, usually in a less formal context than a contract. While it may indicate intentions and basic responsibilities, it lacks the specificity and enforcement mechanisms found in an SLA regarding the configuration, maintenance, and security aspects of cloud services.

A non-disclosure agreement (NDA) is designed to protect sensitive information shared between parties and does not address the roles related to configuration, maintenance, or security in cloud service management. Its primary purpose is to ensure confidentiality rather than to outline operational responsibilities.
