Wireless Topic 5 - Migrating Standalone APS To Lwapp's

Explanation
A standalone AP typically has a console port that allows for direct management and configuration of the device. This console port is used for connecting a computer or terminal to the AP using a console cable, enabling administrators to access the AP's command line interface (CLI) and make changes to its settings. Therefore, the statement "A standalone AP has a console port" is true.

Explanation
The correct answer is Option 1 and Option 2. Option 1, DHCP, can be used to automatically assign an IP address to a standalone AP. Option 2, Static through the CLI, allows the administrator to manually assign a specific IP address to the AP using the command line interface. Option 3, TFTP, is not used for assigning IP addresses but rather for transferring files. Option 4, DNS, is used for translating domain names to IP addresses and is not directly related to assigning IP addresses to APs.

Explanation
Console to it using a console cable and the console port does not require an IP address as it is a direct connection to the device. However, Telnet, Web browsing, and SSH all require an IP address as they are network-based methods of accessing the device.

Explanation
When converting from standalone to lightweight mode, two things are required: an upgrade image and a WLC (Wireless LAN Controller). The upgrade image is needed to install the necessary software for the lightweight mode, while the WLC is required to manage and control the lightweight access points. The DHCP server and upgrade tool are not specifically mentioned as requirements for this conversion process.

Explanation
DHCP server logs can be used to obtain the IP address of the AP because when the AP connects to the network, it requests an IP address from the DHCP server, and the server logs this information. CDP (Cisco Discovery Protocol) can also be used as it allows network devices to share information about themselves, including their IP addresses. IP Setup Utility can be used to configure and obtain the IP address of the AP. However, NTP server statistics do not provide information about the IP address of the AP.

Explanation
It is true that you can apply a separate SSID to different radios. This allows you to have multiple wireless networks on different frequencies or bands, each with their own unique network name. However, the given answer is false, suggesting that it is not possible to apply a separate SSID to different radios. This is incorrect as it is indeed possible to do so.

Explanation
Only one authentication server can be configured. This is because multiple authentication servers would lead to conflicts and potential security vulnerabilities. Having multiple servers could result in inconsistent authentication policies and make it difficult to manage user access and permissions effectively. Therefore, the correct answer is False.

Explanation
To use the Autonomous to Lightweight Mode Upgrade tool, you must obtain the Autonomous to Lightweight Mode Upgrade image from Cisco. This image is necessary to convert the autonomous access point into a lightweight access point. The other options listed (a TFTP server, a WCS, and the correct LWAPP software) may be required for other tasks or configurations, but they are not specifically mentioned as necessary for the Autonomous to Lightweight Mode Upgrade tool.

Explanation
The correct answer is TFTP. TFTP stands for Trivial File Transfer Protocol and is commonly used for transferring files between devices on a network. In the context of the question, TFTP is used for the upgrade from autonomous to lightweight, which refers to the process of converting an autonomous access point to a lightweight access point in a wireless network.

Explanation
After an Access Point (AP) is upgraded, it is necessary for the controller to be reachable in order for the AP to operate properly. This means that the AP needs to establish a connection with the controller to receive instructions and updates. Therefore, the statement "A controller must be reachable after the AP is upgraded for the AP to function" is true.

Explanation
To connect to a defaulted standalone access point, you can use the following methods:

1. Telnet to the access point if it has received an IP address.
4. Use a web browser, enter http://ipaddress, where ipaddress is the IP address assigned to the Ethernet interface of the access point.
6. Use a terminal emulator with the access point's console port, if it has one.

These methods allow you to establish a connection with the access point and configure its settings.

Explanation
Before upgrading the standalone access points to LWAPP and joining them with the WLAN controller, you must configure the following conditions on the WLAN controller:
- Make sure the management interface of the WLAN controller is reachable by the upgraded access points (Option 2).
- Make sure the AP-Manager interface of the WLAN controller is reachable by the upgraded access points (Option 5).
