Microsoft Azure Fundamentals AZ-900 Practice Question

The correct answer reflects the defense-in-depth approach where multiple layers of security are utilized to provide a comprehensive security posture. This model doesn't rely on a single defense mechanism but instead utilizes a variety of security measures that work in unison to protect data, applications, the network, and ultimately the organization's resources against a diverse range of threats. The model is designed in such a way that if one layer fails, additional layers provide continued protection. The incorrect answers do not accurately summarize the purpose of the defense-in-depth model; focusing on a particular aspect, such as encryption or cost-effectiveness, does not provide a complete picture of the multi-layered strategy implied by the model.
