Minimum Data Weeks for Unique Recommendations per Machine Group

Correct Answer: C.

Option A, B, D are incorrect.

Option C is correct.

Security Center needs at least two weeks of data to define the unique recommendations per group of machines.

Machines that have recently been created, or which belong to subscriptions that were only recently enabled with Azure Defender, will appear under the No recommendation tab.

Reference:

Adaptive Application Control is a feature in Azure Defender that enables organizations to prevent unauthorized applications from running on their machines by defining a list of trusted applications.

When using Adaptive Application Control in Azure Defender, it needs to analyze the behavior of the machines over a period of time to identify the trusted applications that are commonly used in the organization. This analysis is based on machine learning algorithms that can detect patterns in the application usage across the organization.

According to Microsoft's documentation, Azure Defender needs at least 4 weeks of data to define the unique recommendations per group of machines. This means that after 4 weeks of monitoring, Azure Defender will be able to provide personalized recommendations for each group of machines in the organization based on their application usage.

It is important to note that this is a minimum requirement, and the actual time needed to generate accurate recommendations may vary depending on the size and complexity of the organization's IT environment. Additionally, organizations can further customize their Adaptive Application Control policies by manually adding trusted applications or blocking unauthorized ones.
