Refer to the exhibit. The P2P Blocking Action option is disabled on the WLC. The security team has a new requirement for each client to retain their assigned IP addressing as the clients move between locations in the campus network. Which action completes this configuration?
To ensure that each client retains their assigned IP address as they move between locations in the campus network, you should enable the Static IP Tunneling option. Static IP Tunneling is designed to allow clients with static IP addresses to move seamlessly across different subnets managed by different Wireless LAN Controllers (WLCs). This feature effectively maintains the client's IP address consistency, preventing any disruptions or address conflicts as they roam within the network.
Static IP Tunneling - allows clients to travel between different WLC on the network and retain connectivity even if the static ip is in a different subnet. https://mrncciew.com/2013/03/25/static-ip-clients-mobility/
The question states "requirement for each client to retain their assigned IP addressing". I've never heard static IP addresses referred to as "assigned". Assignment always implies a DHCP server. So I read this as, which option allows the devices to retain their DHCP assignment. Going with D. Could be wrong. If it isn't D, then it is an extremely poorly worded question.
To ensure that each client retains their assigned IP addressing as they move between locations in the campus network, you should Enable the Static IP Tunneling option (A). Static IP Tunneling is a feature that allows a client device with a static IP address to roam across access points, while still maintaining its original IP address. This is particularly useful in a campus network where clients move between locations but need to keep their assigned IP addresses for consistent network communication. This feature can be enabled on the Wireless LAN Controller (WLC)
The option that completes this configuration is D. Check the DHCP Addr. Assignment check box. By checking the DHCP Addr. Assignment check box, the WLC will retain the assigned IP address for each client as they move between locations in the campus network. This is because the WLC will act as a DHCP server and assign the same IP address to the client each time they connect to the network, based on the client's MAC address. Enabling the Static IP Tunneling option (option A) creates a virtual private network (VPN) between two WLCs or between a WLC and another device such as a router, but it does not address the requirement of retaining the assigned IP addressing for clients as they move between locations. Disabling the Coverage Hole Detection option (option B) is not related to the requirement of retaining the assigned IP addressing for clients. Setting the P2P Blocking Action option to Forward-UpStream (option C) allows clients to communicate with each other directly, but it does not address the requirement of retaining the assigned IP addressing for clients as they move between locations.

assigned ip means they dynamically assigned and D is the only answer that makes sense. even chat AI agrees
A is correct
"At times you may want to configure static IP addresses for wireless clients. When these wireless clients move about in a network, they could try associating with other controllers. If the clients try to associate with a controller that does not support the same subnet as the static IP, the clients fail to connect to the network. You can now enable dynamic tunneling of clients with static IP addresses." "Dynamic anchoring of static IP clients with static IP addresses can be associated with other controllers where the client’s subnet is supported by tunneling the traffic to another controller in the same mobility group. This feature enables you to configure your WLAN so that the network is serviced even though the clients use static IP addresse." https://www.cisco.com/c/en/us/td/docs/wireless/controller/7-4/configuration/guides/consolidated/b_cg74_CONSOLIDATED/b_cg74_CONSOLIDATED_chapter_010011000.html
Configuring Dynamic Anchoring of Static IP Clients (GUI) Procedure Step 1 Choose WLANs to open the WLANs page. Step 2 Click the ID number of the WLAN on which you want to enable dynamic anchoring of IP clients. The WLANs > Edit page is displayed. Step 3 Choose the Advanced tab to open the WLANs > Edit (Advanced) page. Step 4 Enable dynamic anchoring of static IP clients by selecting the "Static IP Tunneling" check box. Step 5 Click Apply to commit your changes.
