This statement is true. In the leader AP networking architecture, one AP acts as the leader AP, taking on controller-like functions similar to those of a WAC for a small or medium-sized WLAN deployment. It can centrally manage other Fit APs and deliver unified wireless configurations such as SSIDs, security settings, and radio parameters. CAPWAP is used for management and control communication between the leader AP and the managed Fit APs.
This architecture is useful in scenarios where deploying a dedicated WAC is unnecessary or uneconomical, but centralized AP management is still desired. It provides a balance between simplicity and control and is commonly used in branch offices, small campuses, and similar environments. HCIA-Datacom explains leader AP networking as an intermediate solution between fully autonomous AP deployment and full WAC + Fit AP enterprise architecture. The key point is that the leader AP behaves as the management node for the other APs and enables unified configuration and control. Therefore, the statement correctly describes both the role of the leader AP and the use of CAPWAP in this architecture.

Option B: OSPF supports triggered updates, allowing routing tables to be updated only when changes occur, conserving bandwidth.
Option D: OSPF supports area division, which is essential for optimizing large networks and limiting the scope of link-state advertisements.

RSTP (Rapid Spanning Tree Protocol) combines the Blocking, Listening, and Disabled states into Discarding, reducing the number of states to Discarding, Learning, and Forwarding. RSTP does not use a separate Listening state, as in standard STP.

In a WAC + Fit AP architecture, the WAC (Wireless Access Controller) centrally manages and controls the Fit APs, so option A is correct. Service configurations such as SSIDs, security policies, radio parameters, and access control are generally delivered from the WAC to the APs.
The Fit AP mainly forwards wireless user traffic and executes the configuration issued by the controller.
Option D is also correct because a Fit AP provides 802.11 wireless access for stations (STAs) and serves as a bridge between the wireless side and the wired network. This is one of its basic roles in enterprise WLAN deployment.

When a switch receives an untagged frame from a user host on an access interface, it associates that frame with the VLAN configured on the interface. In this scenario, PC1 and PC2 are in VLAN
10, and GE1/0/2 is an access interface in VLAN 10. After SW1 receives the frame from PC1, it internally associates the frame with VLAN 10, so option A is correct in the practical VLAN- processing sense used in HCIA-Datacom questions.
When the frame is forwarded out an access interface toward PC2, the switch sends it without a VLAN tag, because end hosts normally do not process 802.1Q tags. Therefore, option D is correct.
