The command ' debug mobility handoff enable ' is used to validate the mobility control packets between Wireless LAN Controllers (WLCs). This command enables debugging of the handoff process, which is critical for ensuring seamless client roaming between controllers. When WLCs are separated by firewalls, it is essential to confirm that mobility control packets can traverse these firewalls without being dropped or rejected. The ' debug mobility handoff enable ' command allows network administrators to monitor the handoff process in real time and identify whether mobility PDUs are being exchanged successfully. If mobility control packets are being blocked by the firewall, this debug output will show failures in the handoff sequence. This command directly validates bidirectional mobility traffic flow, making it the correct troubleshooting tool for the scenario described. Options A and D are not valid Cisco WLC commands. Option C enables configuration-level mobility debugging but does not specifically validate handoff packet flow.

In Ekahau Site Survey, when planning a warehouse deployment using patch (directional) antennas, the antenna downtilt setting is the critical adjustment made when placing simulated APs on the floor plan map. Patch antennas have a defined radiation pattern with a main lobe that must be aimed precisely at the intended coverage zone. In a warehouse environment, APs with patch antennas are typically wall-mounted and aimed down aisles. The downtilt angle determines the vertical component of the antenna ' s aim — adjusting the downtilt in Ekahau tilts the simulated antenna ' s main radiation lobe downward toward the warehouse floor and the working zone of RF scanner devices, rather than projecting RF energy horizontally at an ineffective angle. Ekahau allows engineers to specify the horizontal and vertical orientation of the antenna in three dimensions, and the downtilt value directly controls how the software models the antenna ' s coverage pattern in the vertical plane. AP channel (Option A) is set during channel planning, not during AP placement. Wi-Fi technology (Option B) determines the modulation and protocol standard but is set as an AP property. AP transmission power (Option D) controls cell radius but is set separately from antenna orientation.

In Ekahau Site Survey ' s multi-floor predictive modeling workflow, alignment points are the critical mechanism that allows the software to understand the precise vertical spatial relationship between floors in a multi-story building. Once floor plans are imported with their scale correctly defined, alignment points must be placed on each floor at the same real-world physical location — such as a stairwell corner, elevator shaft, or structural column — so that Ekahau can accurately calculate vertical signal propagation and inter-floor RF bleed. Without alignment points, the software has no spatial reference to determine which area on Floor 2 is directly above a given point on Floor 1, making floor-to-floor signal bleed calculations geometrically impossible. Drawing coverage areas (Option A) is a post-AP-placement activity. Starting the auto planner (Option B) would attempt to place APs without the required spatial reference. Choosing AP models (Option D) is a subsequent step. Alignment points are a fundamental requirement for any predictive survey involving multi-floor buildings.
