QUESTION 12

An engineer installed a 3702 AP and is getting power from the switch. What is the reason for getting 3×3 MIMO instead of 4×4?

 

A.

802.1p

B.

802.3af

C.

802.11e

D.

802.3at

 

Correct Answer: B

 

 

QUESTION 13

A customer is deploying a mesh outdoor wireless network based on FCC standards where spectrum analysis shows significant radar energy propagating throughout the coverage area from a local weather station. Which channel must be excluded from the access points RRM calculation to avoid network disruption due to weather radar activity?

 

A.

132

B.

44

C.

11

D.

36

 

Correct Answer: A

Explanation:

Weather radars operate within the 5600- to 5650-MHz band, which means that channels 124 and 128 might be affected, but also channels 120 and 132 might suffer from weather radar activity.

QUESTION 14

An engineer is determining the signal levels for the wireless cells. Which signal-to-noise ratio is an optimal configuration to achieve?

 

A.

minimum SNR of -33 dBm

B.

minimum SNR of -25 dBm

C.

minimum SNR of 25 dB

D.

minimum SNR of 33 dB

 

Correct Answer: C

Explanation:

The mi
nimum recommended wireless signal strength for voice applications is -67 dBm and the minimum SNR is 25 dB.

QUESTION 15

An engineer is assigned to assist a customer by estimating the number of access points needed to provide voice-grade wireless coverage in a carpeted office space. How many access points should be estimated to cover this space of roughly 38,000 square feet?

 

A.

17

B.

10

C.

6

D.

13

 

Correct Answer: D

Explanation:

The rule of thumb coverage plan is 1 AP per 5,000 square feet for data and 1 per 3,000 square feet for voice and location services.

QUESTION 16

An engineer is deploying centralized wireless solution with a 5508 controller. What is the most AP licenses that can be supported?

 

A.

100

B.

250

C.

1000

D.

500

 

Correct Answer: D

Explanation:

You can order Cisco 5500 Series Controllers with support for 12, 25, 50, 100, 250 or 500 APs as the controller’s base capacity. You can add additional AP capacity through capacity adder licenses available at 25, 50, 100 and 250 AP capacities. You can add the capacity adder licenses to any base license in any combination to arrive at the maximum capacity of 500 APs.

QUESTION 17

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.

 

Correct Answer: B

 

 

QUESTION 18

A network engineer is preparing for an office site survey with a height of 2.5 meters. Which three components are recommended to complete the survey? (Choose three.)

 

A.

Use APs with external antennas.

B.

Use DoS attack on APs while measuring the throughput.

C.

Use APs with built-in antennas.

D.

Use a battery pack to power APs.

E.

Use a drawing of the office space to draw AP and client placements.

F.

Use APs with directional antennas.

 

Correct Answer: CDE

 

 

 

 

QUESTION 19

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

 

Correct Answer: C

 

 

QUESTION 20

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 customer’s 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.
