CWNA-106 Real Exam Questions

ABC Company has a 2.4 and 5 GHz WLAN deployment. DFS functionality is enabled as required by the regulatory domain and APs use DFS channels as long as radar is not detected. Band steering is also enabled to encourage dual-band clients to use frequency bands with more capacity. Your performance analysis shows that many dual-band VoWiFi client devices will move back and forth between 2.4 and 5 GHz as the users roam throughout the building. All APs have 2.4 and 5 GHz radios enabled with transmit power adjusted to accommodate relatively similar cell sizes. This "band hopping" behavior is viewed by network staff to be undesirable. What is the most likely cause of the unpredictable client band selection behavior?

If an 802.11 RF transmission reaches a receiving antenna simultaneously by direct and reflected paths, what effect will the reflected signal have on the signal that took the direct line-of-sight path?

You are implementing a VHT-capable AP. Which one of the following channels is available in the 802.11ac amendment to the 802.11-2012 standard, which was not available in the standard before this amendment?
