Final answer:
Assigning permanent administrators to select customer accounts is not a technique used to mitigate the level of increased risk from privileged users in the cloud data center.
Step-by-step explanation:
The correct answer is option A. Assigning permanent administrators to select customer accounts is not a technique used to mitigate the level of increased risk from privileged users in the cloud data center.
Assigning permanent administrators to select customer accounts would actually increase the risk, as it gives those administrators ongoing access to multiple customer environments. This increases the potential for abuse or unauthorized access.
To mitigate this risk, cloud service providers typically implement techniques such as separation of duties, enhanced logging of administrative activity, granting privileged access only on a temporary basis, and two-person control.
