The use of Datagram Transport Layer Security (DTLS) as a standards-based encryption method for the traffic tunnel in office extension access points (APs) is significant due to its ability to secure the communication between the access point and the controller. DTLS, designed to provide privacy and reliability, offers security features similar to TLS (Transport Layer Security), but is optimized for datagram protocols, making it suitable for wireless communication where packet loss is more common.

In the context of office extension APs, DTLS ensures that data packets transmitted over the untrusted network are encrypted, protecting both confidentiality and data integrity. By implementing DTLS, organizations can safeguard against various security threats, including eavesdropping and tampering with the data in transit, thereby maintaining a secure communication channel essential for operations.

This choice indicates a focus on secure transmission methods that address potential vulnerabilities associated with wireless communications. While other options like CAPWAP and LWAPP refer to protocols used for control and data forwarding between APs and controllers, they do not specifically represent encryption techniques. AES, while a widely recognized symmetric encryption standard, is not the method used for the traffic tunnel in this scenario. Therefore, DTLS is the correct answer as it directly addresses the requirement for securing traffic in
