QUESTION 32

Customer requirements and a WLAN site survey require a Cisco 1250 AP operating at full 802.11a/b/g/n located approximately 150 meters from the closest IDF. What is the best solution to provide wireless coverage to this portion of the customer’s facility?

 

A.

At the AP location, install a power drop and a Cisco Aironet Power Injector Media Converter (AIR-PWRINJ-1000AF) to power and the Cisco 1250 and extend the Cat 5 link.

B.

Install an external Cisco Mid-Span 802.3af power injection panel in the same rack as the access switch to extend the driven distance of the structured cable plant.

C.

At the AP location, install a power drop and a Cisco Aironet Power Injector Media Converter (AIR-PWRINJ-FIB) for the Cisco 1250. Then connect a Cat 5 cable from the AP to a fiber-optic-to-copper transceiver which connects to a fiber link to the IDF. At the access switch, connect the fiber cable from the AP location to a fiber-optic port on the switch.

D.

At the AP location, install a power drop and a Cisco AIR-PWRINJ4 power adapter for the Cisco 1250. Connect the Cat 5 cable to the AP from the IDF.

E.

At the AP location, install a local power drop and local power supply for the Cisco 1250.

Connect the AP through a pair of fiber-optic-to-copper transceivers back to the access layer switch to provide data access.

Correct Answer: E

 

 

QUESTION 33

You have completed a site survey for a customer that refurbishes/remanufactures automobile engines. The site survey has determined that there are approximately 70 clients in the facility, but because of the large number of engines as many as 2500 RFID tags will need to be tracked through location services to provide historical location information and audit trails. The results of the site survey require 60 APs for data and location services. How many version 7.0 controller(s) will provide the most cost effective solution?

 

A.

1 Cisco Catalyst 6500 Wireless Services Module generation 2 (WiSM 2) with a 100 AP license

B.

3 Cisco 2500 controllers with 25 AP licenses

C.

< p class="MsoNormal" style="margin: 0cm 0cm 0pt; line-height: normal; text-autospace: ; mso-layout-grid-align: none" align="left">2 Cisco 2500 controllers with 50 AP licenses

D.

1 Cisco 5500 controller with a 50 AP license and a 25 AP license upgrade

 

Correct Answer: D

 

 

QUESTION 34

You have a customer that is building a new campus of four 3-story buildings that you have just completed the site survey for. The customer is interested in the amount of rack space they will need to allocate in either the building MDF or in the data center for controllers. Each building is going to require 75 APs to support voice and data. How should the controllers be deployed to provide the least number of controllers, the highest redundancy, and the easiest management?

 

A.

Use the distributed deployment method in each building MDF with the N + N redundancy method.

B.

Use the centralized deployment method in the data center with the N + N + 1 redundancy method.

C.

Use the distributed deployment method in each building MDF with the N + 1 redundancy method.

D.

Use the centralized deployment method in the data center with the N + 1 redundancy method.

E.

Use the distributed deployment method in each building MDF with the N + N +1 redundancy method.

F.

Use the centralized deployment method in the data center with the N + N redundancy method.

 

Correct Answer: B

 

 

QUESTION 35

Which two options indicate the RF channels regulated by 802.1h for outdoor deployment regarding FCC? (Choose two.)

 

A.

36, 40, 44, 48

B.

52, 56, 60, 64

C.

100, 104, 108, 112

D.

149, 153, 157, 161

E.

165

 

Correct Answer: BC

 

 

 

 

 

QUESTION 36

How would clients react to a controller configuration that utilized unsupported channels?

 

A.

Unsupported channels can cause coverage holes for clients as well as limit their connectivity.

B.

Unsupported channels would be ignored by clients.

C.

Unsupported channels would have no impact on clients. The user would simply need to roam to a supported channel.

D.

Unsupported channels are not configurable on the controller, thus there would be no impact on clients.

 

Correct Answer: A

 

 

QUESTION 37

For better compatibility with 802.11n clients, which 802.11a channels should be utilized?

 

A.

UNII-2 Band – extended channels

B.

UNII-1 Band

C.

UNII-3 Band

D.

ISM Band

 

Correct Answer: B

 

 

QUESTION 38

Which two of the following are considered best practices upon the completion of a wireless installation? (Choose two.)

 

A.

Consult with the customer to ensure that the IT staff has a complete set of design and installation documents.

B.

Test all the customer’s wireless devices and applications to ensure they are working properly.

C.

Make sure the customer is aware that they should consider purchasing a support contract immediately after the installation is complete.

D.

Spend time with the customer showing them the controller GUI as well as inform them how they can reach the Cisco TAC if they have any problems.

 

Correct Answer: AB

 

 

QUESTION 39

When using WCS 7.0 to calibrate a floor in a facility, which two factors are common to the point and linear calibration methods? (Choose two.)

 

A.

You must go through each collection point at a speed that isn’t too fast to collect too much information nor too slow which limits the amount of information collected.

B.

You must sample both the 802.11a/n and the 802.11b/g/n network separately.

C.

If one collection point in the linear or point collection method is missed, you have to start at the beginning again.

D.

Rotating the client is only required during the point collection process because the linear method is a slowly moving process.

E.

You will only need to combine the linear and point collection methods in special spaces like hallways.

 

Correct Answer: AB

 

 

QUESTION 40

After you have run the VoWLAN Voice Readiness Tool in WCS 7.0, you see there are potential problem areas in your facility. Which two actions will help you troubleshoot these coverage areas? (Choose two.)

 

A.

Verify the green, yellow, and red regions in the RF environment only if the floor has not been calibrated.

B.

To prevent one-way audio, set the AP power levels to half the power of the client. This will ensure proper radio coverage.

C.

You need to edit the RSSI values for Cisco IP Phones so the 802.11b/g/n radios display the region map properly.

D.

Determine if the coverage area will have enough APs to support the VoWLAN client, since all APs must have a Tx power level that does not exceed that of the client.

E.

Set the AP power level to match the VoWLAN client to avoid one-way audio.
