Which one of these statements is a possible reason for the failure?

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?

What is most likely the root cause?

Company XYZ needs to establish network connectivity to a newly acquired, adjacent building less
than 1 kilometer (3280 feet) away. The project calls for implementing a wireless solution using
autonomous access points in a point-to-point bridging solution using external antennas on
interface dot11radio1. You need to secure the bridge link with strong EAP, DOT1x, and WPA
methods, using a local RADIUS server. However, the link cannot be established and the following
message is observed in the logs: “DOT1X_SHIM-3-SUPP_START_FAIL: Unable to start
supplicant on Dot11Radio1.” What is most likely the root cause?

What is most likely the root cause of these duplicate frames?

Company ABC is implementing a point-to-point bridging solution to a building approximately 3
kilometers (1.86 miles) away. The equipment used will be two autonomous access points set to
frequency 2412 Mhz with external antennas. The bridge link will be authenticated using an
external RADIUS server. While looking at the interface statistics, the network administrator
observes duplicate frames in the receive counters. What is most likely the root cause of these
duplicate frames?

Which two of the below actions would you recommend?

You have been hired by an organization that would like to grow their wireless deployment from
150 to 300 users. They only have 200 available addresses on the current wireless subnet and are
looking for recommendations on how to overcome this limitation. They have already created a
second interface in another subnet that provides 200 additional addresses to accommodate the
additional users. Which two of the below actions would you recommend? (Choose two.)
