  B. Option B

  C. Option C

  D. Option D

  Correct Answer: C

  CDP and LLDP can coexist, or be used at the same time, especially if your network environment is made up of devices from different vendors. The majority of Cisco devices will also support LLDP, as this allows them to interoperate with other vendors. However, in those devices, LLDP is off by default.

• Question 229:

  A WLC sends alarms about a rogue AP, and the network administrator verifies that the alarms are caused by a legitimate autonomous AP.

  A. Place the AP into manual containment.

  B. Remove the AP from WLC management.

  C. Manually remove the AP from Pending state.

  D. Set the AP Class Type to Friendly.

  Correct Answer: D

  A WLC will send alarms about a rogue AP when it detects an AP that is not under its management. This can happen when a legitimate autonomous AP is installed on the network. To stop the alarms, the network administrator must set the AP Class Type to Friendly. This will tell the WLC that the AP is a legitimate AP and that it should not send alarms about it.

  The other options are incorrect for the following reasons:

  Removing the AP from WLC management will stop the alarms, but it will also prevent the WLC from managing the AP. This is not necessary, since the AP is a legitimate AP. Placing the AP into manual containment will stop the alarms, but it will also prevent the AP from being used by clients. This is not necessary, since the AP is a legitimate AP. Manually removing the AP from Pending state will not stop the alarms. The WLC will continue to send alarms about the AP until the AP Class Type is set to Friendly.
