The ClO of a company wants to start tracking inventory in the warehouse using RFID tags and their existing wireless network. The company hires a wireless engineer to ensure that their existing network can support this new initiative.
Which tool in Cisco Prime can help the wireless engineer?
A. Planning Mode
B. Map Editor
C. Site Survey
D. Location Readiness
Using Chokepoints to Enhance Tag Location Reporting
Installation of chokepoints provides enhanced location information for RFID tags. When an active Cisco-compatible Extensions Version 1-compliant RFID tag enters the range of a chokepoint, it is stimulated by the chokepoint. The MAC address of this chokepoint is then included in the next beacon sent by the stimulated tag. All access points that detect this tag beacon then forward the information to the controller and location appliance.
Which two steps are associated with the active portion of the audit when a post-installation audit is performed with an auditing tool such as Ekahau? (Choose two.)
A. Check for co-channel interference by standing near an access point on one channel and watching for other access points that are on the same channel.
B. Verify smooth roaming.
C. Check to see if the signal level on other access points that are heard on the same channel is at least 19dBm weaker than the access point that you are next to.
D. Check that all channels are supported by the APs, regardless of client capabilities.
E. Verify that the network traffic of physical data rate and packet loss meets user requirements.
A wireless phone user is having roaming difficulties and is experiencing gaps in the conversation while roaming. WLC WLAN is configured as IEEE 802.1X and WPA2 and Aironet information element.
What should be configured to fix the problem?
A. IEEE 802.1X with Cisco Centralized Key Management
B. IEEE 802.1X EAP-FAST
C. DHCP required and DHCP proxy on WLC
D. WPA1 and PSK
When designing a WLAN, AP placement is important.
Which option describes how to rank the density of APs needed to support location services versus data and voice services?
A. Data services have the lowest density of APs compared to location services, which has the highest density.
B. Data services have a lower density of APs compared to location services, but more than voice.
C. Voice services have the highest density of APs over location and data services.
D. Voice and data services require a higher density of APs than location services.
A wireless engineer is configuring VoWLAN on a WLC.
Which configuration should be implemented on the router or switch that is connected to the WLC?
A. The interface on the switch or router should trust the CoS settings of the WLC.
B. The interface on the WLC should mark all packets as EF.
C. The interface on the switch or router should strip all CoS markings on the IEEE 802.11 header.
D. The interface must be configured as a Layer 3 interface.
We recommend that the QoS policy on the router/switch interfaces connected to the WLC be set to trust the CoS settings of the WLC. This means that the wired network responds to the CoS values controlled by the QoS policy set on the WLC. The WLC does not enforce any policy that changes the WLAN client DSCP values. The WLC policy effects will only be seen in the CoS values associated with the WLAN client traffic. If the routers and switches connecting to the WLC are set to trust DSCP, then a DSCP policy must be created and maintained on those router and switch interfaces―in addition to the policies applied on the WLC. For more information on WLAN QoS and traffic classification, refer to the Chapter 3, "Voice over WLAN Radio Frequency Design."
An engineer is performing a predictive wireless design for a medical treatment environment, which requires data and voice services.
Which of the following is a requirement for the design?
A. overlapping -72 dBm coverage from two access points
B. overlapping -67 dBm coverage from two access points
C. continuous -67 dBm coverage from one access point
D. continuous -72 dBm coverage from one access point
An 802.11n implementation is being discussed. Users are satisfied with the potential 300-450 Mbps throughput of new 802.11n APs.
Which three bandwidth requirements are used to calculate per client bandwidth through an 802.11n AP network? (Choose three.)
A. 450 Mbps throughput is the client max for 5-GHz radio.
B. Channel bonding on 5 GHz is required for a client to have a 300 Mbps WiFi link.
C. 300 Mbps throughput is the client max for 2.4-GHz radio.
D. The remaining bandwidth is divided per device when more clients are connected to one AP.
E. 100 Mbps Ethernet switch port is a potential bottleneck.
F. CleanAir helps clear noise for 802.11n channel bonding to work.
A corporation has a Cisco Unified Wireless Network that has been deployed for voice coverage. The wireless data rates have been tuned to mandatory rates of 18 Mbps and 36 Mbps. Some wireless clients have been experiencing drops streaming multicast video while moving throughout the building.
What is the cause of the drop in video?
A. Clients are maintaining a 12Mbps rate and cannot receive the stream at 18Mbps.
B. Clients are not roaming due to coverage. This is causing the multicast data to drop due to the client re-associating often.
C. Clients are roaming at lower data rates and are not maintaining 36Mbps connectivity.
D. Clients are connected at 18Mbps; however, other clients are connecting at 12Mbps and are causing the multicast video to degrade.
