A bank must activate a new access-point image across a trading floor. Neighbors cover the same desks. How should the reloads be arranged so a desk is not left with every nearby access point down?
Select an answer to reveal the explanation.
Short Explanation
If every access point at a desk reboots together, that desk has nowhere to roam. Stagger your reloads so a neighbor stays up. Sniffer mode does not keep a radio serving through a reload, and clearing the country code turns radios off.
Full Explanation
When neighboring access points cover the same area, rebooting them all at once removes the only radios a client can roam to. Staggering the reloads, a rolling activation, keeps at least one neighbor up while another installs the new image. That is the maintenance arrangement that protects the trading desks. Reloading every access point at the same moment does the opposite. Clients cannot roam to a controller. The controller is not a radio. Sniffer mode takes an access point out of client service for a capture. Putting the floor into sniffer mode before a reload removes coverage even earlier, and sniffer mode does not keep clients roaming. Clearing the country code disables transmission. Radios do not stay up through an image change because the country was removed, and they would remain down after the upgrade until the country was set again. Exam caveat: staggering only works if the neighbors really overlap. A warehouse aisle with a single access point still goes dark when that one reloads, and the stagger has to be between access points that actually cover each other. Operational check: during the first wave, confirm a test client on a desk roams to a neighbor that has not reloaded yet, then reload that neighbor in a later wave.
