NEW QUESTION # 52
A customer has two Cisco 5520 WLCs that manage all APs throughout the network. The WLCs are in different locations to provide geographical redundancy. A mobility group has been configured on both WLCs and has an UP status on both controllers. The APs in location A are statically configured to use controller A as the primary and controller B as the secondary. If the WLC in location A goes offline, the APs successfully join the WLC in location B, but they do not fail over to their primary configured controller when it recovers. Which configuration task fixes the issue?
Answer: A
Explanation:
Enabling AP fallback globally on the WLC allows access points to reconnect to their primary controller after they have connected to a secondary controller due to the primary being offline.
This is the exact behavior described in the scenario -- APs successfully fail over to the secondary WLC but do not return to the primary WLC when it recovers. AP Fallback is a WLC-level setting that monitors the availability of each AP's configured primary controller and initiates a reconnection when the primary becomes reachable again. Without AP Fallback enabled, APs remain on whatever controller they most recently joined -- in this case, the secondary -- even after the primary recovers.
NEW QUESTION # 53
A customer is building a new warehouse facility that has only its foundation and perimeter walls built. The building will be complete in the next eight months. The customer needs a detailed bill of materials and costs for a wireless network that must support RF scanners throughout the warehouse. How should the survey be performed?
Answer: C
Explanation:
A predictive survey (also called a virtual or model-based survey) is the appropriate and only feasible methodology for a facility that does not yet physically exist in its complete form. Since the warehouse has only its foundation and perimeter walls, it is impossible to conduct any form of physical (active or passive) survey of the complete environment. A predictive survey uses architectural floor plans imported into a tool such as Ekahau Site Survey, where the engineer defines attenuation areas representing planned materials and structures: concrete block walls, steel shelving racks, metallic surfaces, and other warehouse-specific obstructions. The software models RF propagation through these defined attenuation values, enabling accurate AP placement planning, antenna selection, and channel planning without physical access to the complete facility. The output is a validated bill of materials with AP counts, models, and associated infrastructure requirements. Passive surveys (Options A and C) require physical APs transmitting RF signals to collect measurement data - impossible in an incomplete building. A hybrid approach mixing passive survey with predictive modeling introduces measurement errors from the incomplete physical state.

NEW QUESTION # 54
A network engineer must design a new Cisco wireless solution that contains three Cisco 9800-40 WLCs.
WLC1 and WLC2 will be combined into one logical unit with SSO and a backup WLC named WLC3 will be joined by using a mobility tunnel. Link redundancy between the WLCs and the switches is required. Which WLCs must the design provide connectivity to the network equipment for LAG to be effective in an SSO failover scenario?
Answer: D
Explanation:
In a Cisco Catalyst 9800 SSO deployment using Link Aggregation Group (LAG) for network interface redundancy, the SSO pair - WLC1 (active) and WLC2 (standby) - must both have their physical interfaces connected to the network infrastructure as part of the LAG bundle. LAG on the 9800 in an SSO configuration is implemented as a multi-chassis LAG across both the active and standby controllers. This means both WLC1 and WLC2 contribute physical member links to the port channel, and the connected switches must have LACP or PAgP bundle members from both controllers in the same port channel group. When an SSO failover occurs - WLC1 fails and WLC2 takes over as active - the LAG remains operational because WLC2 ' s physical links are already established members of the bundle and continue forwarding traffic without any link renegotiation. If only WLC1 had LAG connectivity and WLC2 had independent links, an SSO failover would cause a LAG topology change requiring re-convergence, introducing downtime. WLC3 is a separate N+1 backup controller joined via a mobility tunnel - not part of the SSO pair and its LAG configuration is independent.

NEW QUESTION # 55
A customer wants to provide wireless coverage in a parking lot outside of a building. An engineer determines that three APs are required. The APs can be mounted on the light poles in the parking lot because there are cable routes already in place for these locations. The closest wiring closet is approximately 200 meters away. Which setup powers and connects the APs back to the customer network?
Answer: D
Explanation:
This question hinges on a fundamental network engineering constraint: the maximum transmission distance of copper Ethernet cabling. IEEE 802.3 standards specify a maximum segment length of 100 meters (328 feet) for all standard PoE and Ethernet over Category 5e, 6, or 6A UTP copper cabling. The parking lot light poles are approximately 200 meters from the closest wiring closet -- more than double the maximum copper distance. This immediately eliminates Options A and D, which specify Category 6 UTP cabling: at 200 meters, UTP copper cannot reliably carry Ethernet at any supported speed, and PoE cannot be delivered over this distance regardless of standard. The correct solution is fiber optic connectivity between the wiring closet and the parking lot, combined with a local AC/DC power module at each pole location.
Fiber optic cabling supports single-mode runs of kilometers and multi-mode runs of hundreds of meters at Gigabit speeds -- easily spanning 200 meters. At the AP mounting location on the light pole, an AC/DC power module (powered from the pole's existing electrical supply) converts AC power to the DC power the AP requires. Option B (fiber with 802.3af) is incorrect because PoE cannot be delivered over fiber -- 802.3af requires copper cabling for simultaneous power and data delivery.
NEW QUESTION # 56
Users who leave the office with a wireless headset must be able to hand oft the voice call with minimal disruption. The engineer drafted four possible Door plans for AP placement:
* red dots and arrows represent the direction of travel
* blue dots represent the AP placements
Which floor plan provides the requested functionality?
A)
B)
C)
D)
Answer: D
Explanation:
VoWLAN handoff quality is fundamentally determined by the AP placement strategy relative to the direction of user movement. When a user is in motion carrying an active voice call, the roaming event must occur before signal quality degrades below the minimum acceptable VoWLAN threshold (typically -67 dBm for voice, with a minimum SNR of 25 dB). This requires the user to encounter increasing signal strength from a neighboring AP before the current AP ' s signal drops below the threshold. The optimal AP placement follows the principle of overlapping coverage along the predicted path of travel - APs must be positioned so that as a user moves, they progressively enter the coverage zone of the next AP while still within adequate range of the current one. Floor plan B represents the correct design where APs are positioned along the travel path with sufficient cell overlap (typically 15-20%) to ensure seamless 802.11r fast BSS transitions. Incorrect floor plans place APs perpendicular to travel direction, at path endpoints only, or with insufficient overlap zones - all of which create roaming dead zones where the handoff occurs too late, causing voice call disruption.
