Motorola Solutions Design WLan Solutions Sample Questions:
Question 1
The wireless network that your team is preparing to implement has been found to be surrounded by a number of unsecured hot-spots. A junior administrator proposes that WPA/WPA2-PSK would be a sufficient mechanism since the section is not a high security area. Everyone agrees that WPAAVPA2-PSK would be an appropriate mechanism. A senior member of the staff mentions that WPA/WPA2-PSK can be administratively intensive. Which of the following situations would NOT cause additional administrative work when using WPA/WPA2-PSK (select TWO)?
A. The update of the laptops to newer models
B. The theft of a single laptop
C. The replacement of the RADIUS server
D. The need to replace an AP
E. The replacement of the domain controller issuing the keys
Question 2
You have been working on the design specification for a new WiNG 5 WLAN for a new customer. The client needs wireless internet connectivity as well as voice over IP (VoIP) in two key auditoriums of their sports center. Your team has just created a LANPlanner report and the design calls for 11 APs. The customer had identified 2 client locations (Location A and Location B) that he would like to discuss with you.
Assume that the VoIP applications you will be deploying are constrained by the parameters outlined in the table below.
Given the constraints of the VoIP applications, which of the following is TRUE at 2,4GHz? Use the relevant VoIP Handsets Application map in the LANPlanner - Sports Center exhibit at the bottom.
Given the constraints of the VoIP applications, which of the following is TRUE at 2.4GHz? Use the relevant VoIP Handsets Application map in the LANPlanner - Sports Center exhibit at the bottom.
A. Clients at both the locations are served.
B. Clients at Location B are served but not at Location A.
C. Clients at Location A are served but not at Location B.
D. Clients at both the locations are not served.
Question 3
Your latest project is to provide wireless coverage to a large 4 story residential structure. The customer requires a low cost and quickly implemented solution for this structure. Which of the following access point combinations would you recommend?
A. Use AP6511s for room coverage and AP6532s for public areas
B. Use AP650s and AP6511s for public areas
C. Use AP7131sthroughout the entire facility
D. Use AP621s for room coverage and AP7131s for public areas
Question 4
You are designing a WLAN for a new customer and have been given a Customer Checklist for WLAN.
Given this checklist, please answer the test item(s) below.
Assume this implementation now requires support for SMART RF. This being the case, what is the MOST likely effect this would have on the design?
A. You wouldn't need to modify the design to support SMART RF
B. You will need to add another switch to support SMART RF
C. You will need less APs as SMART RF will compensate for the coverage holes
D. You may need more APs to provide the overlap of coverage needed to support SMART RF functionality
Question 5
You are importing AutoCAD files into LAN Planner. You want to assemble a floor with other floors (stack the floors). You must perform the assembly using the:
A. Format Floor dialog
B. Floor Wizard
C. Building Wizard
D. Format CAD Drawing dialog
