When the primary controller (WLC-1) goes down, the APs automatically get registered with the secondary controller (WLC-2).

The APs register back to the primary controller when the primary controller comes back on line.

Raising the minimum data rate requires that a client be closer to the AP where it can get the higher SNR needed to associate with it.

D is correct. A Yagi antenna contains a dipole but also has reflectors and directors.

Effective Isotropic Radiated Power

The radiated (transmitted) power is rated in either dBm or W. Power that comes off an antenna is measured as effective isotropic radiated power (EIRP). EIRP is the value that regulatory agencies, such as the FCC or European Telecommunications Standards Institute (ETSI), use to determine and measure power limits in applications such as 2.4-GHz or 5-GHz wireless equipment. In order to calculate EIRP, add the transmitter power (in dBm) to the antenna gain (in dBi) and subtract any cable losses (in dB).

The AP will attempt to resolve the DNS name CISCO-CAPWAP-CONTROLLER.localdomain. When the AP is able to resolve this name to one or more IP addresses, the AP sends a unicast CAPWAP Discovery Message to the resolved IP address(es). Each WLC that receives the CAPWAP Discovery Request Message replies with a unicast CAPWAP Discovery Response to the AP.

Answer is B.

The question states that SW2 is not running Cisco. Therefore it cannot run PaGP (which according to the snippet, SW3 is configured as). So it has to be changed to either channel-group active or passive to do LACP.

EAP-FAST is a flexible EAP method which allows mutual authentication of a supplicant and a server. It is similar to EAP-PEAP, but typically does not require the use of client or even server certificates.

It can't be A because this is not a static one to one NAT.

It can't be B because outside local is the private address of the destination, it has nothing to do with the network that we are configuring.

It can't be E because 1) its a private IP address 2) we specify the inside global pool in the 2nd command.

It has to be C) because we "assign" (aka permit with the ACL) the 10.1.1.0/27 block to be NATed.

It has to be D) for the same obvious reason, we state this block to be the inside global pool in the command.

Adaptive 802.11rTheconfiguration is to all devices, but the adaptive 11r feature will only be applied to supporting iOS devices running iOS 10 or later. All other devices will be able to associate using standard WPA2(including Mac clients)
