True or False: Access to a parent node guarantees access to all its child nodes in the Department Security Tree.

• A. True
• B. False
• C. Only for top-level nodes
• D. Only if the parent is the root

Answer: (A)

In a Department Security Tree, permissions typically cascade downward: if you have access to a parent node, that access is inherited by all of its descendants. This means granting permission at a higher level automatically covers every subunit beneath it, so you can reach all child nodes without needing separate permissions for each one. For example, access to a department implies access to all its teams and subteams under it.

The statement is true because the hierarchy is built so permissions flow down the tree, ensuring the entire subtree is accessible once the parent is. The other ideas—only applying to top-level nodes or only when the parent is the root—would disrupt this consistent downward inheritance across the whole subtree.
