Question 2

A customer has two Cisco wireless controllers named WLC-A and WLC-B. Each controller is in a different building on a campus. The WLCs have different Layer 3 interfaces and broadcast the same SSIDs from their respective APs. Users must remain connected to the same VLAN and maintain their IP addresses during roaming from the APs attached to WLC-A and WLC-B. Which action accomplishes the requirement?

A. Create a mobility group between the two WLCs to allow auto-anchoring.

B. Enable 802.11r on each SSID on both WLCs to allow caching of the PMK.

C. Create an SSO cluster to ensure that client sessions sync between WLCs.

D. Enable AP groups using the same name on both WLCs for each group.

Question 3

Which issue occurs when wireless access points transmit by using the highest power level in a building that has brick walls?

A. reflection

B. hidden node

C. wideband interference

D. narrowband interference

Question 4

An engineer is designing a FlexConnect deployment for 40 remote branch offices, each with a 10 Mbps WAN circuit back to a central Catalyst 9800 WLC. Which design consideration must be validated before deployment?

A. Each branch must have a local WLC for AP registration.

B. The round-trip latency between the AP and the WLC must not exceed 20 ms.

C. All WLANs must be configured for central switching.

D. The round-trip latency between the AP and the WLC must not exceed 300 ms.

Question 5

A company has three Cisco WLCs that are joined as a mobility group. Mobility multicast messaging is enabled. All the WLCs in the mobility group communicate via a multicast. Which configuration must be identical between the three WLCs to validate communication?

A. interface IDs

B. multicast IP address

C. service port IP address

D. management IP address

Question 6

During a validation survey of a newly deployed WLAN, the engineer measures -70 dBm at the cell edge on a data-only WLAN, but the noise floor is -78 dBm. Which conclusion should the engineer reach?

A. The design meets the requirement because noise floor is not a design parameter.

B. The design fails because SNR is only 8 dB, well below the required minimum.

C. The design meets the coverage requirement because RSSI is above -72 dBm.

D. The design fails because RSSI must be above -60 dBm for all WLANs.

Question 7

Refer to the exhibit. A network engineer is designing a high availability SSO on a Cisco Catalyst
9800- 40 WLC with multi-LAG network redundancy on two Catalyst 9300 switches. The LAG requirements are: ?Each LAG must be connected to a single switch. ?Different VLANs must be assigned to different LAGs. ?The controller must learn the identity of partners that can support LAG capabilities in each port. ?When any active LAG ports fail, a standby LAG port must provide redundancy. Which protocol must be used for the port channel on the interface to meet the design requirements?

A. PAgP

B. OSPF

C. BGP

D. LACP
