In OSPF, the "Full" state signifies that the neighbor relationship has been fully established, with both routers synchronized and their LSDBs updated. This state is achieved after exchanging and acknowledging Link State Advertisements (LSAs) between the neighbors, marking the completion of OSPF adjacency​.

Detailed Explanation:In a tree topology, nodes are arranged hierarchically with root nodes at the top and leaf nodes at the base. This structure is often used in larger networks because it supports scalability and easy addition of nodes. However, if a higher-level node (e.g., root or intermediate node) fails, all dependent nodes in its subtree lose connectivity. Therefore, faults at higher layers have a more significant impact than faults at the leaves. (Reference: HCIA-Datacom Training Material, Network Topology Types)

A direct route (also called a connected route) is automatically created when an interface is assigned an IP address and is up.

Option A (Incorrect): The administrator does NOT need to manually configure a direct route. It is automatically added when an IP is assigned to an interface.

Option B (Incorrect): Direct routes have a higher priority than dynamic routes (e.g., OSPF, RIP, etc.).

Option C (Correct): Direct routes have the highest priority among all routing types (default priority = 0, which is the highest).

Option D (Incorrect): Static routes have a lower priority (default 60) than direct routes (0).

Thus, the correct answer is C (The direct route has the highest priority.)
