Data labels could include all the following, except?

Data labels are crucial for understanding how to handle information within an organization. They typically indicate important aspects such as how data should be accessed, distributed, and classified based on sensitivity.

Distribution limitations refer to rules governing who can share or distribute the data and under what conditions it can be shared. Access restrictions indicate who is permitted to access the data and under what circumstances, thus ensuring that sensitive information does not fall into the wrong hands. Confidentiality level provides clarity on the degree of sensitivity associated with the data, informing users about how to treat the information, such as personal data requiring more stringent controls.

In contrast, multifactor authentication is a security measure rather than a data label. It's designed to enhance access security by requiring multiple forms of verification before granting access to systems or data. While it plays a critical role in securing data access, it does not classify or label the data itself, making it the outlier among the options presented.
