A network engineer is troubleshooting connectivity issues between two WLCs running 8.x code in SSO mode and finds that the redundancy management heartbeat is failing. Which packet type must be filtered for heartbeats when taking a capture to verify communication?
RSTP
UDP
TCP
ICMP
A customer has multiple WLCs running N+1 redundancy with APs equally distributed. Only one WLC is a designated backup for all other WLCs so the customer must ensure that the most critical APs remain registered or get priority over other APs in case of a WLC failure. However, the customer notices on WLC failure that some critical APs remain unregistered What needs to be addressed in the design?
AP fallback is not enabled on the backup WLC.
AP failover priority is not enabled globally on the backup WLC.
AP failover priority is not enabled globally on the failed WLC.
AP fallback is not enabled on the failed WLC.
WLC SSO is set up between two WLCs in a service provider network serving public spaces. On WLC failover, it is noticed that only about half of the original client count is now showing on the secondary WLC, although it is currently showing the role as active. Which design side case explains the issue?
The secondary WLC platform does not support the required client count.
The WLCs had not completed database sync before the primary failure.
SSO is not configured correctly.
Some client sessions were in WebAuth-Req state before failover.
Refer to the exhibit.
An engineer is about to establish a mobility peer connection between a Cisco Catalyst 9800-CL version 16.10.1e and Cisco AireOS 5520 version 8.8.120.0. The data path between the 9800-CL and AireOS 5520 is down, but its control path is up. Based on the configuration, what is the cause of the issue?
The certificate hash key is incorrect leading to data path down.
The data-link-encryption configuration is missing from the 9800-CL configuration.
Encrypted mobility is being used in the 5520 configuration leading to data path down.
CAPS is used to key in MAC address in the IOS_XE configuration leading to data path down.
A customer is deploying an 802.11ac network on a oor to support approximately 300 wireless devices. Which setting must be changed on Cisco Prime Infrastructure Planning Tool to predict the number of APs the customer needs to service the new oor?
Demand Settings
Data Coverage Support Margin
802.11n Protocol Support
Add AP Field
An engineer added an AP to a deployment after a post-installation site survey. The engineer then notices an increase in co-channel interference and retransmissions. Which two features help mitigate the issue? (Choose two.)
Cisco Compatible Extensions
Transmit Power Control
Enhanced Distributed Channel Access
Coverage Hole Detection
Dynamic Channel Assignment
When a wireless survey is conducted at a customer facility, signal attenuation in an area that is surrounded by thick glass walls is noted as 2dB. When Cisco Prime Infrastructure is configured, which obstacle must be placed in a map editor to represent the impact that the glass wall will have on the RF signal in the facility?
heavy door
glass
thick wall
light wall
While performing an AP-on-a-stick survey with a cell boundary of -67 dBm, an engineer is consistently reading SNR less than 15 dB in a particular area within the cell boundary. What is causing this issue?
Another signal is interfering with the AP.
The engineer forgot to compensate for the wall type in that area.
The AP transmit power is too low.
The engineer is too far from the AP.
An engineer must perform a Layer 2 survey for a mining facility. Which type of antenna does the engineer use in the mine shaft?
omnidirectional
patch
internal
dipole
An engineer is designing a wireless network to support hyperlocation in an environment that already has APs installed. During the survey, the engineer notices that the APs are pointing in different directions. What is the recommended way to align the APs to easily determine AP
Azimuth, X-Y, and ceiling height information, and minimize confusion and user-entered errors?
APs must be aligned pointing toward the nearest wall.
APs must be aligned pointing toward each other.
APs must be aligned in the same direction.
APs can be aligned all four ways.
