   • Adata
   • Bmanagement
   • Ccontrol
   • Daction

   Show answer

   Answer: B

   Explanation

   B is correct Management frames: Used for joining and leaving a wireless cell.

7. Question 1157 · 1334 in bank

   Which functionality is provided by the console connection on a Cisco WLC?

   • AHTTP-based GUI connectivity
   • Bsecure in-band connectivity for device administration
   • Cout-of-band management
   • Dunencrypted in-band connectivity for file transfers

   Show answer

   Answer: C

   Explanation

   Console port dedicated for out-of-band management and local access. The management interface is the default interface for in-band management/administration of the controller. The service interface is reserved for out-of-band management of the controller. To access WLC GUI, we can use HTTP/HTTPS over a browser. Here, service port interface or the management interface is used to access GUI. https://www.lantronix.com/blog/whats-difference-console-port-management-port/

8. Question 1158 · 1334 in bank

   

   Refer to the exhibit. Host A switch interface is configured in VLAN 2. Host D sends a unicast packet destined for the IP address of host A.

   

   What does the switch do when it receives the frame from host D?

   • AIt floods the frame out of every ports except the source port.
   • BIt creates a broadcast storm.
   • CIt shuts down the source port and places it in err-disable mode.
   • DIt drops the frame from the MAC table of the switch.

   Show answer

   Answer: A

   Explanation

   Technically Host D should send an ARP request, which the switch will then flood out of all other interfaces on the same VLAN. Host A will reply and the switch will update its MAC address table based on the ARP reply, allowing the subsequent unicast frame to be forwarded immediately to Host A. But if it sent the unicast frame directly, it would simply be flooded out of all interfaces other than the one it was received on, but only those in the same VLAN. So in this case the e0/0 and e0/2 interfaces. So technically no answer is correct.

9. Question 1159 · 1334 in bank

   Select 2

   

   Refer to the exhibit. A Cisco engineer creates a new WLAN called lantest. Which two actions must be performed so that only high-speed 2.4-Ghz clients connect? (Choose two.)

   • AEnable the Status option.
   • BSet the Radio Policy option to 802.11g Only.
   • CSet the Radio Policy option to 802.11a Only.
   • DSet the Interface/Interface Group(G) to an interface other than guest.
   • EEnable the Broadcast SSID option.

   Show answer

   Answer: AB

   Explanation

   A is correct since the status option needs to be checked to enable the wireless LAN B is correct since 802.11g only allows 2.4Ghz client to connect to the network C is incorrect since 802.11a will enable 5Ghz clients to connect to the network. D vlan groups/interfaces is used to associate traffic with a specific vlan in the wired network and it is not relevant to our question. E is incorrect, the question didn't ask us to broadcast the network

10. Question 1160 · 1334 in bank

    How does Rapid PVST+ create a fast loop-free network topology?

    • AIt uses multiple active paths between end stations.
    • BIt requires multiple links between core switches.
    • CIt maps multiple VLANs into the same spanning-tree instance.
    • DIt generates one spanning-tree instance for each VLAN.

    Show answer

    Answer: D

    Explanation

    The correct answer is D A is incorrect having multiple active paths between end stations causes loops in the network. B I couldn't find how is it related to the question C is done through MST (Multiple spanning tree) protocol https://networklessons.com/spanning-tree/multiple-spanning-tree-mst https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus5000/sw/layer2/503_n1_1/Cisco_n5k_layer2_config_gd_rel_503_N1_1_chapter9.html
