An engineer performs a wireless site survey of a multi-floor building for 2.4-GHz and 5-GHz bands. The customer wants to identify non-802.11 sources of interference. Which survey measurement must be included in the survey?
Answer: B
An engineer is deploying new APs to serve IEEE 802.11g through 802.11ac clients and wants to use the Ekahau Site Survey tool to verify RF coverage. Management wants the engineer to verify and create coverage maps as quickly as possible. Which configuration accomplishes the goal?
Answer: A
A. Using passive mode with two wireless adapters in the Ekahau Site Survey tool allows for simultaneous scanning of multiple channels, thereby expediting the creation of accurate RF coverage maps. Active surveys, on the other hand, can be more time-consuming as they require the client device to associate with access points and perform data transfers, which is less efficient for quickly mapping coverage areas.

A customer currently is migrating the old wireless infrastructure to a new Cisco IOS XE-based solution and wants a mobility group configured between a Cisco AireOS WLC and an IOS XE WLC. During the migration phase from AireOS to IOS XE, the Layer 3 roaming between the WLCs must be seamless. Which action meets the requirements?
Answer: D
An engineer has been tasked with optimizing roaming for all the wireless networks used by shops located in a shopping center. A unique WLAN is assigned to each individual shop named ret470632970B55XX, where the last two digits indicate the shop’s location. The wireless network consists of 9800 controllers and Cisco 9100 APs. What should the engineer configure on the controllers to optimize roaming?
Answer: D
An IT administrator is trying to establish the criteria for a predictive coverage design. The environment is a mix of 802.11g data and voice. Which minimum coverage with SNR 25 aligns with Cisco best practice?
Answer: D
Refer to the exhibit. A company is designing a Cisco wireless solution that has two WLCs named WLC1 and WLC2 and several APs. An AP named AP12 is a critical AP and is provisioned to be installed in hallway 6, which is located just outside the office of the company director and must always connect to WLC1. Which priority level must be incorporated in the design for AP12?
Answer: D
From the AP Failover Priority drop-down list, choose one of the following options to specify the priority of the access point: • Low—Assigns the access point to the level 1 priority, which is the lowest priority level. This is the default value. • Medium—Assigns the access point to the level 2 priority. • High—Assigns the access point to the level 3 priority. • Critical—Assigns the access point to the level 4 priority, which is the highest priority level. https://www.cisco.com/c/en/us/td/docs/wireless/controller/7-6/configuration-guide/b_cg76/b_cg76_chapter_01110001.pdf

An engineer must design a predictive site survey. The wireless network must be “location-ready”. Each floor is quite small and has only a few offices. Which approach must be considered?
Answer: D
An engineer is designing a wireless network that will support many different types of wireless clients. When conducting the survey, which client must be used to ensure a consistent experience for all of the wireless clients?
Answer: D
"When designing a Wi-Fi environment and choosing locations for APs or antennas, it is necessary to know the needs of the application and to design for the worst performing clients" - 6.6 Describing and Implementing the Wireless Design Process

An engineer performs a Layer 1 survey by using Metageek Chanalyzer only on the current operating channel. Which operating mode is configured for a Cisco CleanAir AP?
Answer: B
Answer is B: "In Local Mode, each Cisco CleanAir-enabled access point radio provides air quality and interference detection reports for the current operating channel only." "In Monitor Mode, the access point provides air quality and interference detection reports for all monitored channels." "SE-Connect Mode enables a user to connect Chanalyzer directly to a Cisco CleanAir access point when the access point is not connected to a controller. The access point provides air quality and interference detection reports for all monitored channels." https://support.metageek.com/hc/en-us/articles/200591105-Connecting-Chanalyzer-to-a-Cisco-CleanAir-Access-Point

A customer has multiple WLCs running in N+1 redundancy with APs load balanced between the WLCs. The customer performs AP failover testing between the WLCs and notices that some of the APs do not move back to their primary WLC after it recovers. What are two points that must be addressed in the design? (Choose two.)
Answer: DE
If AP Fallback is not enabled on all WLCs, only the APs connected to WLCs with this feature enabled will return to their primary WLC once it recovers.
