Suppose that you have just received news that no users can connect with a newly installed AP. Which one of the following bits of information would be important when you search for the AP’s name from the WLC? (Choose all that apply.)

Suppose that you have just received news that no users can connect with a newly installed AP. Which one of the following bits of information would be important when you search for the AP’s name from the WLC? (Choose all that apply.)

• The AP has a valid IP address.
• The AP is not found.
• The AP has no channel numbers listed for the 2.4 and 5 GHz bands.
• The AP has a valid MAC address.

Explanation: The first three choices are important facts in troubleshooting the connectivity issues. For example, if you see a valid IP address listed for the AP, then it must be properly connected to the wired network, have appropriate power, and have discovered and joined the WLC. As a result, you can probably rule out wired connectivity problems at the AP. If the AP is not found in the WLC search, then the AP might not be powered on, might not have an IP address, or might not have discovered the WLC. Therefore, users would not be able to use the AP at all. If the AP has no channel numbers shown, then perhaps the wireless bands have not been enabled on the WLC, so the users have no BSS to discover and join. Knowing that the AP has a valid MAC address probably has no relevance at all because all APs are preconfigured with valid MAC addresses at the factory.
