What is a function of Wireless LAN Controller?

1. A. register with a single access point that controls traffic between wired and wireless endpoints.
2. B. use SSIDs to distinguish between wireless clients.
3. C. send LWAPP packets to access points.
4. D. monitor activity on wireless and wired LANs

Correct Answer: C
Lightweight APs (LAPs) is devices require no initial configuration. LAPs use the Lightweight Access Point Protocol (LWAPP) to communicate with a WLAN controller (WLC), as shown in the below figure. Controller-based APs are useful in situations where many APs are required in the network. As more APs are added, each AP is automatically configured and managed by the WLC.

Which capability does TFTP provide?

1. A. loads configuration files on systems without data storage devices
2. B. provides authentication for data communications over a private data network
3. C. provides encryption mechanisms for file transfer across a WAN
4. D. provides secure file access within the LAN

Correct Answer: A
TFTP (Trivial File Transfer Protocol) is a simple file transfer protocol that is often used to transfer configuration files or firmware to network devices, such as routers or switches, during the boot process. TFTP is lightweight and lacks advanced features like authentication or encryption, making it suitable for basic file transfer operations in situations where security is not a primary concern. Therefore, option A accurately describes one of the primary capabilities of TFTP. It is commonly used to load configuration files onto systems, particularly those without extensive data storage devices, during the initialization or configuration process.
