A. B. C. D.C.
In a greenfield RF site survey, the goal is to determine the best locations for access points (APs) in a wireless network. During this survey, it's important to know the exact location and identity of each AP being tested. One way to ensure this information is captured is to enable a specific information element (IE) in the AP's beacon frame.
Information elements are fields within the beacon frame that convey specific information about the wireless network. Different IEs are assigned specific numbers for identification purposes. To display the hostname of each AP during a site survey, you would need to enable a specific IE that conveys this information.
The correct answer to the question is D. IE 221. This IE is called the "Vendor Specific Information" element, and it can be used to convey a variety of vendor-specific information about an AP, including the AP's hostname. By enabling IE 221 in the AP's beacon frame, your site survey software will be able to capture the hostname of each AP being tested.
It's important to note that different vendors may use different IE numbers to convey similar information. Therefore, it's always a good idea to check the documentation for your specific APs to determine the correct IE to enable for displaying the AP hostname during a site survey.
