Demo Questions
Question 1
You are designing a WLAN for 50 branch offices that require central management. Which controller architecture do you use?
- per-branch local controllers
- anchor controllers
- FlexConnect controllers
- autonomous access points
Correct answer: C
Question 2
A customer reports that wireless clients are not able to receive multicast data from known working multicast servers on the wired network. The client is connecting at the highest mandatory wireless rate of 24 Mbps and the wireless controller is configured for multicast-unicast mode. What three actions should the engineer take next to troubleshoot the issue? (Choose three.)
- verify that the L3 interfaces are configured for pim sparse-dense-mode on the VLAN servicing the wireless access points as well as the wireless controller's management VLAN
- change the wireless controller from Multicast-Unicast mode to Multicast-Multicast mode and assign a multicast address in the 239.X.X.X/8 subnet
- verify that IGMP snooping is disabled on the wireless controller since the access points are handling IGMP messages from the clients
- verify that Global Multicast mode has been enabled
- make sure the highest mandatory rate is set to 54 Mbps so that the multicast traffic has sufficient bandwidth
- verify Multicast Listener Discovery (MLD) v1 snooping has been enabled to keep track of and deliver IPv4 multicast flows
Correct answer: ABD
Question 3
An engineer is tuning RRM parameters to improve client connectivity. Which channel band results in the best 802.11n client compatibility?
- UNII-2
- UNII-2e
- UNII-3
- UNII
- UNII-1
Correct answer: E
Explanation:
802.11n operates on the same channel as 802.11a. For better compatibility with 802.11n clients, it is recommended to stay on lower channels (UNII-1 band).
