A customer has a business-critical voice network and wants to be alerted whenever voice clients move out of a coverage area and experience RSSI below -67 dBm on the 5 GHz band. Which option can be configured on the wireless controller to alert network administrators when this limit is surpassed?
- A. EDCA; voice optimized
- B. SIP voice sample interval
- C. 802.11a voice RSSI coverage threshold
- D. traffic stream metrics
Answer : C
While performing a Layer 1 passive wireless site survey of a location an engineer detects several instances of low power frequency hopping interference, but cannot physically locate the interfering device or devices. Why is the engineer unable to locate the offending device or devices?
- A. The sources are nearby narrow-beam radar and are sweeping through the facility.
- B. The sources are PAN and are mobile.
- C. The sources are above the ceiling file and transmit intermittently.
- D. The sources are actually high-powered devices and transmit from off the site.
Answer : B
What are two advantages of conducting an active survey versus a passive survey when verifying RF coverage?

- E. verifies interferers
Answer : A,B
An engineer installed a 3702 AP and is getting power from the switch. What is the reason for getting 3x3 MIMO instead of 4x4?
- A. 802.1p
- B. 802.3af
- C. 802.11e
- D. 802.3at
Answer : B
An engineer is assigned to replace an older data-grade autonomous wireless network with a Cisco controllerbased wireless network to meet Voice over WLAN needs. The customer also wants all existing cable infrastructure to be reused and no new cable be specified.
How should the engineer respond to the customers requirements?
- A. Implement the wireless network with the restraints and decrease the TPC neighbor threshold to increase Txpower to provide overlapping cell coverage at sufficient SNR to provide for Voice over WLAN service.
- B. Implement the wireless network with the restraints and utilize high-gain antenna to provide overlapping cellcoverage at sufficient SNR to provide for Voice over WLAN service.
- C. Inform the customer that the network will not likely function as desired and a post install survey with thepossibility of some new cable would be recommended.
- D. Inform the customer that it is not possible to provide coverage and quality for Voice over WLAN usingexisting AP locations and an entire overbuild will be necessary.
Answer : C
