Question 1

Based on a wireless network design, an engineer configured a primary and secondary controller for their APs. A power interruption caused the primary Cisco WLC to go down, and, as expected, all APs joined the secondary controller. When the primary controller came back up, all the

APs remained joined to the secondary controller. Which approach must the engineer take for the APs to move back to the primary?

ASet AP Fail over Priority to 4 on each AP.

BSet AP Fallback to Enabled on the secondary controller.

CSet AP Fallback to Enabled on the primary controller.

DSet AP Fail over Priority to Critical globally.

Answer : C

AP Fallback is a feature that allows APs to rejoin their primary controller after they have connected to a secondary controller due to a failure. By enabling AP Fallback on the primary controller, the APs will automatically rejoin it when it becomes available again after a power interruption. This ensures that APs return to their designated primary controller for normal operations.

Question 2

When designing for high-density environments such as stadiums, which is MOST important?

AUse of omnidirectional antennas

BIncrease transmit power of APs

CUse of directional antennas with sectorization

DDeploying APs only on 2.4 GHz

Answer : C

Question 3

Which two criteria must be considered when conducting an outdoor bridge site survey? (Choose two.)

Anear-far effect

Bweather

Ctraffic lights

Dpower lines

EFresnel zone

Answer : B, E

When conducting an outdoor bridge site survey, weather and the Fresnel zone are critical criteria to consider. Weather can affect signal propagation and the reliability of the wireless link, while the Fresnel zone relates to the elliptical area around the line-of-sight path between transceivers, which must be clear of obstacles to ensure a strong signal.Reference: Designing Cisco Enterprise Wireless Networks (ENWLSD 300-425)

Question 4

When conducting a site survey for real-time traffic over wireless, which two design capabilities of smartphones and tablets must be considered? (Choose two.)

Ano support for 802.11ac

Bhigher data rates than laptops

Cfewer antennas than laptops

Dno support for 802.11r

Elower data rates than laptops

Answer : C, E

Smartphones and tablets typically havefewer antennasthan laptops, which can affect their signal reception and transmission capabilities. Additionally, they often supportlower data ratescompared to laptops due to their smaller size and power constraints.

Question 5

APs in a remote office recently have been converted from local mode to FlexConnect to take advantage of the local switching. After the change, remote wireless users report voice quality issues and bad quality on wireless IP phones while roaming. A debug is performed, and it is noticed that the 802.11r Fast Transition is not working as expected, like on local mode AP, though the same WLAN configuration is in place. What is the cause of the issue regarding the FlexConnect APs?

AThey do not support 802.11r FT.

BThey must be added into AP groups along with a common RF profile.

CThey must be in a FlexConnect group to support 802.11r FT.

DThey must be added to AP groups to support fast roaming methods.

Answer : C

FlexConnect APs must be in a FlexConnect group to support 802.11r Fast Transition (FT). This grouping allows for local authentication and key management, which are necessary for fast roaming methods that improve voice quality and wireless IP phone performance during roaming.

Question 6

A customer has two locations named building 1 and building 2 Each location has a Cisco wireless network with these components

Building 1

* 2 Cisco Catalyst 9800 Series Wireless Controllers in a high availability cluster

* 50 Cisco Catalyst 9100 APs

* Contractor SSID in VLAN 100

* Corporate SSID in VLAN 200

* mobility group configured to the building 2 WLCs

Building 2

* 2 Cisco Catalyst 9800 Series Wireless Controllers in a high availability cluster

* 20 Cisco Catalyst 9100 APs

* Contractor SSID in VLAN 300

* Corporate SSID in VLAN 400

* mobility group configured to the building 1 WLCs

The customer has a new security requirement mandating that all contractor SSID traffic must terminate on VLAN 100 on the building 1 WLCs for all locations. Which design approach must the engineer take?

AUse the building 2 WLCs as foreign controllers and building 1 as anchor controllers tor the contractor SSID traffic.

BUse the building 2 WLCs as anchor controllers and building 1 as foreign controllers for the contractor SSID traffic.

CUse the WLCs at both buildings as anchor controllers and tunnel the contractor SSID traffic to building 1.

DUse the WLCs at both buddings as foreign controllers and tunnel the contractor SSI0 traffic to building.

Answer : A

Question 7
