Why is 802.11a connectivity reduced in an X-ray room?

A. X-rays create significant non-Wi-Fi interference on the 802.11a band. B. X-rays impact the 802.11a UNII-2 channels that cause access points to dynamically change channels. C. X-rays within these rooms cause multipath issues. D. X-ray rooms exhibit increased signal attenuation.

What is the attenuation value of a human body on a wireless signal?

A. 3 dB B. 4 dB C. 6 dB D. 12 dB

During a wireless network design, a customer requires wireless coverage on the perimeter of a building but also wants to minimize signal leakage from the wireless network. Which antenna should be used to accomplish this design?

A. omnidirectional B. patch C. monopole D. dipole

An engineer at a global enterprise organization must ensure that a mesh deployment has the highest number of channels available to the backhaul, regardless of region deployed. Which design meets this requirement?

A. redundant controllers in the least restrictive regulatory domain B. redundant controllers in the most restrictive regulatory domain C. one controller per continent D. one controller per country code

A customer is looking for a network design with Cisco Hyper__cpLocation using AP4800 for __cpLocation tracking via a custom mobile app. Issues appeared in the past with refresh rates for __cpLocation updates. What needs to be implemented to meet these requirements?

A. Cisco CMX SDK in the __cpLocation app B. device Bluetooth via the app C. Cisco FastLocate technology D. redundant CMX and fetch __cpLocation in round-robin fashion

An engineer must perform an assessment of a customer LAN for a future IEEE 802.11ac Wave 2 wireless deployment. All access switches are Fast Ethernet- capable only, and the wired infrastructure between existing APs and access switches is based on the CAT 6A standard. Which two actions provide maximum support of Cisco 3800 Series access points? (Choose two.)

A. Replace the existing switches with mGig switches. B. Ensure that cable distances between access switches and APs are not longer than 55 meters. C. Replace the existing switches with gigabit switches with 10 G uplinks. D. Ensure that cable distance between access switches and APs are not longer than 100 meters. E. Replace the existing wiring infrastructure with the CAT-7E wiring standard.

A network engineer is working on a predictive WLAN design. The new wireless network must support access to Internet, email, voice, and the inventory database.
To successfully support these services, which configuration must the engineer use for the signal strength levels and SNR on the planning tool?

A. signal strength of -67 dBm, 20-dB SNR, and maximum 5 percent packet loss B. signal strength of -70 dBm, 30-dB SNR, and maximum 10 percent packet loss C. signal strength of 67 dBm, 20-dB SNR, and maximum 1 percent packet loss D. signal strength of -67 dBm, 25-dB SNR, and maximum 1 percent packet loss

An engineer is designing a new wireless network. The network needs to meet these requirements:
- support a high wireless client concentration
- support data over wireless
- support voice over wireless
- avoid interferenceWhich design approach should be taken?

A. 5 GHz frequency band with channel bonding, to support 40 MHz channels B. 5 GHz frequency band without channel bonding, to support 20 MHz channels C. 2.4 GHz frequency band without channel bonding, to support 20 MHz channels D. 5 GHz frequency band with channel bonding, to support 80 MHz channels

An enterprise is using the wireless network as the main network connection for corporate users and guests. To ensure wireless network availability, two standalone controllers are installed in the head office. APs are connected to the controllers using a round-robin approach to load balance the traffic. After a power cut, the wireless clients disconnect while roaming. An engineer tried eping from the controller but fails. Which protocol needs to be allowed between the networks that the controllers are installed?

A. IP Protocol 67 B. IP Protocol 77 C. IP Protocol 87 D. IP Protocol 97

A customer called with a requirement that internal clients must be on different subnets depending on the building they are in. All APs are operating in local mode and will not be modified, and this is a single controller solution. Which design approach creates the desired result?

A. Create FlexConnect groups, place the access points in, and set the correct VLAN to SSID mapping based on location. B. Create mobility anchors for the SSID, and on the controller under the internal SSID, create a foreign map to the desired VLAN based on location. C. Create AP groups for each desired location, map the correct VLANs to the internal SSID, and add the APs for that location. D. Create an SSID, place it to the desired VLAN under WLANs, and configure 802.1x in ISE to assign the correct VLAN based on the SSID from which the client is authenticating.
