Answer: A

Explanation:

A Cisco Office Extend access point (Cisco OEAP) provides secure communications from a Cisco WLC to a Cisco AP at a remote location, seamlessly extending the corporate WLAN over the Internet to an employee’s residence. The user’s experience at the home office is exactly the same as it would be at the corporate office.

Datagram Transport Layer Security (DTLS) encryption between the access point and the controller ensures that all communications have the highest level of security. Cisco OEAPs are designed to work behind a router or other gateway device that is using network address translation (NAT). NAT allows a device, such as a router, to act as an agent between the Internet (public) and a personal network (private), enabling an entire group of computers to be represented by a single IP address. There is no limit to the number of Cisco OEAPs that you can deploy behind a NAT device.
