QUESTION 41
When using WCS 7.0 to calibrate a floor, is it more important to collect 50 or more distinct locations or to collect 150+ measurements?
A. 150+ measurements are more important than the locations because the information gathered is more granular.
B. Collecting 50 or more distinct locations is more important because this provides a wider coverage across the floor being calibrated.
C. Depending on the size of the floor 50+ distinct locations and 150+ measurements may provide divergent information that requires more data collection.
D. When calibrating a floor 50 or more distinct locations will yield 150+ measurements because multiple measurements are collected at each distinct location.
Answer: D
QUESTION 42
Refer to the exhibit. In testing the post-deployment WLAN network you have discovered an AP that has been placed in a difficult area. The AP cannot be easily moved because of various requirements. The client performance of various Apple and Microsoft operating system-based products does not meet expectations. Which two options can help mitigate the performance issue? (Choose two.)
A. Add additional APs.
B. Replace the AP with an AP and external antenna.
C. Increase the AP power level to maximum.
D. Change the AP location to one that is less RF hostile.
E. Rotate the AP 90 degrees to change antenna polarity.
Answer: AB
QUESTION 43
In post-deployment testing you have identified an area where there is a substantial rate-shift issue causing problems with the existing Cisco 7921 phones. How might you resolve this issue?
A. Increase the AP power level to maintain higher throughput further away from the AP.
B. Increase client RSSI, SNR, and retry values to maintain connectivity to the original AP for as long as possible.
C. Change VoWLAN to 7925 phones.
D. Reduce the power level of the AP so that roaming occurs before the client experiences the substantial rate shift.
Answer: D
QUESTION 44
You have been asked to evaluate a deployed version 7.0 controller based WLAN, which includes a Cisco WCS and an MSE3310. Currently, the customer has a approximately 1900 clients and 300 RFID tags. The customer is complaining of problems tracking clients and RFID tags. What can be done to correct this problem?
A. Increase the wIPS license on the MSE3310.
B. Replace the MSE3310 with a MSE3355 and increase the wIPS license.
C. Replace the MSE3310 with a MSE3355 and increase the Context-Aware license.
D. Decrease the wIPS license on the MSE3310.
E. Increase the Context-Aware license on the MSE3310.
Answer: C
QUESTION 45
You have been asked to evaluate a new version 7.0 controller-based WLAN deployment. The customer wants to increase the number of indoor tags their network supports. How do you explain to the customer how wireless clients and RFID tags are licensed in the MSE?
A. There is a 2:1 relationship between the number of clients and RFID tags that can be supported in the MSE.
B. The number of clients and RFID tags are independent of each other and have separate license bases.
C. There is a 3:1 relationship between the number of clients and RFID tags that can be supported in the MSE.
D. The relationship between clients and RFID tags is balanced. So if you have more clients you have fewer RFID tags.
E. RFID and wireless clients require separate dedicated MSE appliances.
Answer: D
QUESTION 46
Which type of information should be included in an installation report?
A. A complete characterization of the external WLAN environment.
B. The exact number of users the WLAN will support.
C. Soft copies of configuration for switches, routers, controllers, and location appliances.
D. A detailed description of the WLAN environment during the post-installation testing, for example, number of people present, furniture, no furniture, and sources of interference present.
Answer: C
QUESTION 47
Which two pieces of physical infrastructure information should be included in the installation report presented to the customer? (Choose two.)
A. A list of router and switch models, serial numbers and locations.
B. The total square footage of the customer’s facility.
C. An analysis of the facility exterior wall and roof construction materials.
D. The cable scan results for the entire customer facility.
E. An installation inventory of all controllers and APs in the WLAN coverage area.
Answer: DE
QUESTION 48
What is the biggest challenge a customer faces when they are presented with the post-installation report?
A. Validating the information is correct.
B. Interpreting the configuration parameters and settings for the WLAN devices.
C. Maintaining the report so that once the first change to the WLAN is made the documentation remains current.
D. Maintaining the security of the report so that only IT personnel have access to the information contained in the report.
Answer: C
QUESTION 49
In which two ways does the type of industry vertical change the way you prepare to perform a wireless site survey? (Choose two.)
A. In most cases the specific industry vertical impact is not unique and information used to prepare for a site survey can be reused from one vertical to another.
B. The first step in preparing for a site survey for a specific industry vertical is to review the individual industry standards for a WLAN deployment to ensure compliance with all known standards.
C. Each industry vertical has its own specific challenges that need to be considered prior to completion of the WLAN site survey.
D. Prior to performing a site survey for a customer, their specific industry vertical has very little impact on site survey process. Only post-survey design is impacted by the industry vertical.
Answer: BC
QUESTION 50
What are two reasons that it is always preferable to obtain a digital copy of the “as built” drawings for a site you need to perform a WLAN site survey on? (Choose two.)
A. A digital copy of the “as built” drawings is always more accurate than design drawings because it includes the placement of office furniture.
B. A digital copy of the “as built” drawings includes all the changes made during construction that are not included in the design drawings.
C. A digital copy of the “as built” drawings includes a full set of preliminary mechanical drawings so sources of interference, diffusion, and absorption can be easily identified.
D. A digital copy of the “as built” drawings allows you to more accurately estimate physical AP placement in the customer environment.
E. A digital copy of the “as built” drawings assists in the placement of WLAN equipment so the WLAN signal minimizes wired network delay.
