질문 # 15
A network engineer is designing a new wireless network. The network must include these requirements: ?optimized performance ?avoid interference ?availability in high-density areas ?roaming Which two approaches must be taken? (Choose two.)
정답：A,D
설명：
The design requirements -- optimized performance, interference avoidance, high-density support, and roaming capability -- collectively point to a dual-band strategy using narrow channel widths.
For 5 GHz operation (Option A), 20 MHz channels are the correct choice for high-density and campus- scale deployments. The 5 GHz band has significantly more non-overlapping channels compared to 2.4 GHz (up to 24 non-overlapping 20 MHz channels in UNII-1, UNII-2, and UNII-3), enabling a robust channel reuse plan with minimal co-channel interference and excellent roaming cell separation.
질문 # 16
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?
정답：D
설명：
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. The CAPWAP AP Controller IP Address command (Option A) permanently changes the primary controller configuration on the AP, which is not the intended solution - the AP already has the correct primary configured. DHCP Option 43 (Option B) is used for initial AP discovery, not fallback. AP Failover Priority (Option D) controls which APs are processed first during a failover event, not whether APs return to their primary controller.

질문 # 17
An engineer is designing a wireless network for a small airport and completes the initial walkthrough phase of the facility. Which step of the WLAN site survey should the engineer perform next?
정답：C
설명：
The Cisco WLAN site survey methodology follows a structured, sequential process. The initial walkthrough -- sometimes called the discovery or orientation phase -- is the first step, during which the engineer physically tours the facility to understand its physical characteristics: building materials, structural layout, potential AP mounting locations, wiring closet positions, and environmental factors. After completing the initial walkthrough, the next logical phase is the predeployment survey (also referred to as a pre-deployment or predictive survey). The predeployment survey uses the information gathered during the walkthrough to create a detailed design plan -- either through a manual AP placement plan or a predictive survey tool such as Ekahau, where floor plans are annotated with materials and attenuation values and APs are virtually placed to model coverage. The predeployment survey output is the design document that drives the actual physical installation.
질문 # 18
A wireless consultant must design a Cisco WLAN. The consultant recommends a solution that requires 12 Cisco 9100 Series APs connected to a Cisco 3800 Series PoE+ switch. Each AP requires PoE+ for full functionality. What is the total PoE requirement in watts?
정답：D
설명：
This question requires a straightforward PoE power budget calculation. The IEEE 802.3at standard (PoE+) delivers a maximum of 30W at the Power Sourcing Equipment (PSE/switch port). Cisco 9100 Series access points such as the C9120, C9130, and C9136 are designed to operate with full functionality using PoE+ at
30W per AP. The total PoE power requirement for 12 APs is calculated as: 12 APs × 30W per AP = 360W.
This figure represents the total power draw that the Cisco 3800 Series PoE+ switch must be capable of supplying across the connected AP ports simultaneously. The Cisco Catalyst 3800 Series switches offer a total PoE power budget that must be validated against this 360W requirement during the design phase. Note that some Cisco 9100 APs support higher power modes through IEEE 802.3bt (PoE++), which can provide up to
90W - but the question specifies PoE+ (802.3at) for the switch infrastructure, making 30W × 12 = 360W the correct answer. Option D (720W) would correspond to 24 APs at 30W each. Option B (1080W) would represent 36 APs. Option C (184.8W) corresponds to a non-standard per-AP power value.

질문 # 19
An engineer is using Ekahau Site Survey to create a WLAN plan for a warehouse. The plan is to use patch antennas. Which setting is adjusted when simulated APs are placed on the map?
정답：B
설명：
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.
