Primary Risk

A.

The primary risk when business units procure IT assets without IT involvement is that data security requirements are not considered.

Explanation:

When business units procure IT assets without the involvement of IT, they may not consider the data security requirements that need to be in place to protect sensitive information. IT professionals are typically responsible for implementing and enforcing security measures that are designed to protect the confidentiality, integrity, and availability of information. If IT is not involved in the procurement process, these security measures may not be put in place, leaving the organization vulnerable to security breaches, data theft, and other cyber attacks.

Corporate procurement standards being violated (answer A) is a potential risk but is not as significant as data security concerns. The business units wanting IT to be responsible for maintenance costs (answer B) is a separate issue related to financial responsibility and not as significant as security risks. System inventory becoming inaccurate (answer D) is also a potential risk but is not as significant as data security concerns.

Therefore, the most significant risk associated with business units procuring IT assets without IT involvement is that data security requirements are not considered.
