A network administrator is trying to convert a Cisco Aironet 1250 Series Lightweight Access Point
back to autonomous mode using a TFTP server and AP mode button. DHCP Option 43 is configured,
but the AP is not connected to the controller. Console and physical access to the AP has been
established. The TFTP server is local to the PC and the directory has the original image of “c1250-
k9w7-tar.124-10b.JDA3.tar,” downloaded from Cisco.com. The PC is directly connected to the access
point, but the conversion is failing. Which one of these statements is a possible reason for the
failure?

A.
The 1250 Series AP is a lightweight-only AP and needs a WLC

B.
The image filename is incorrect.

C.
The lightweight AP has to be joined to the WLC and then converted, using the config ap
tftpdowngrade command.

D.
Telnet is not enabled on the AP or WLC

E.
The network administrator needs to use the archive command directly on the AP for this
procedure to complete.
