• Question 643:

  How does a Cisco Unified Wireless network respond to Wi-Fi channel overlap?

  A. It alternates automatically between 2.4 GHz and 5 GHz on adjacent access points

  B. It allows the administrator to assign channels on a per-device or per-interface basis.

  C. It segregates devices from different manufacturers onto different channels.

  D. It analyzes client load and background noise and dynamically assigns a channel.

  Correct Answer: D

  The Cisco Unified Wireless Network is designed to dynamically manage and optimize wireless coverage and performance by constantly monitoring and adjusting to changing conditions. In the case of Wi-Fi channel overlap, the network will analyze client load and background noise and dynamically assign channels to minimize interference and optimize throughput. This ensures that the network can provide reliable and high-performance Wi-Fi connectivity to all clients, even in challenging environments with high levels of interference.

• Question 644:

  An engineer must configure traffic for a VLAN that is untagged by the switch as it crosses a trunk link. Which command should be used?

  B. switchport trunk native vlan 10

  C. switchport mode trunk

  D. switchport trunk encapsulation dot1q

  Correct Answer: B
