Final answer:
Agent handler repositories cannot be seen on distributed repositories due to lack of access permissions.
Step-by-step explanation:
The correct answer is b) Distributed repositories lack access permissions.
Agent handler repositories are typically stored on a central management server and used for managing and distributing policies and tasks to client systems. On the other hand, distributed repositories are local repositories that store the actual software packages and updates. These repositories are meant to be accessed by client systems for software installations and updates.
However, distributed repositories do not have access permissions to view or interact with the agent handler repositories, as these repositories have a different purpose and are not meant to be accessed by client systems directly.
