Motorola Solutions Design WLan Solutions Sample Questions:

1. When designing a network with a single Access Point (AP) and all associated stations it is called a Basic Service Set (BSS) A Basic Service Set Identifier (BSSID) is used to uniquely identify each BSS. The BSSID is typically created by which of the following methods?

A) The virtual BSSID is created from the base MAC address.
B) The virtual BSSID is the physical address of the AP Ethernet port.
C) The virtual BSSID is a common characteristic of all devices in the BSS.
D) The virtual BSSID is assigned by the manufacturer of the WLAN device

2. During the design phase of a medium size, hub and spoke WLAN installation, a discussion of dependent versus independent APs takes place. Which of the following is NOT characteristic of dependent access points (APs)?

A) Dependent APs managed by the same WLAN switch can be set with different security parameters.
B) Dependent APs download firmware and configurations from the WLAN switch.
C) Some dependent APs support redundant Power over Ethernet (PoE) ports.
D) Dependent APs from one vendor can be used with the WLAN switch of another vendor.
E) Dependent APs eliminate problems with co-channel interference.

3. You are conducting interviews with the management team of a new potential customer; a multi-floor medical center located in a multi-tenant office building of a popular suburban business park. To begin, the management team expects to have approximately 100 simultaneous wireless users throughout the medical center using a variety of mission-critical applications, including high performance data for transferring large MRI scans to the handsets of medical personnel, VoWLAN handsets, Push-to-talk (PIT) voice badges, and Real-time Locationing Services (RTLS) mounted on infusion pumps and bio monitor carts. In addition, a separate, publicly accessible Visitor WLAN will offer "best effort" data access for web browsing and limited printing throughout the complex. Over the upcoming months and years, many more users are expected to be added to the WLAN.
Due to the number of users, the variety of the applications, the requirements for QoS and the need for security, you will be recommending an RFS Controller-based solution using dual-band, triple radio 802.11n APs. Which of the following solutions would best solve the many requirements of this customer?

A) Assign PTT and RTLS users to the 5 GHz band. Assign VoWLAN and high performance MRI data users to the 2.4 GHz band. Assign the Visitors WLAN to the third radio configured for the 2.4 GHz band.
B) Assign high performance MRI data, VoWLAN, PIT, and RTLS users to the 2.4 GHz band and Visitors WLAN to the 5 GHz band and keep the third radio in reserve for future use.
C) Assign RTLS and Visitor's WLAN to the 2.4 GHz radio, VoWLAN and PTT to the 5 GHz radio, and high performance MRI data to the third radio configured for the 900 MHz band.
D) Assign Visitors WLAN, PIT, and RTLS users to the 2.4 GHz band. Assign VoWLAN and high performance MRI data users to the 5 GHz band and assign the third radio as a dedicated VVIPS sensor.

4. You are designing a WLAN system and have been using a planning tool (such as LANPlanner). All of the following are reasons you would use the edit/remove access point option, EXCEPT:

A) Adjust antenna parameters
B) Change AP manufacturer/model
C) Change antenna type
D) Change frequency band
E) Indicate Dependent or Independent AP

5. You have been directed to design a new WLAN for a very particular customer. The customer has done a great deal of research using consumer-level trade periodicals and has determined that the best approach will be to use single radio, 2.4 GHz band 802.11b/g/n APs for the best ROI and future growth compatibility. In addition, the customer has determined that your network design should provide sufficient coverage to allow at least a 150 Mbps and preferably a 300 Mbps connection, from anywhere in the premises. Since the customer's location covers approximately 600,000 sq ft.(200,000 sq meters) in a three floor complex you will need to design a frequency reuse pattern for channels 1, 6, and 11 that properly coordinates the co-channel interference influences of the 2.4 GHz band. After thinking about these prerequisites you come to the realization that this network design will not work. Which of the following statements best explains why this network design is unworkable?

A) Problem upgrading wired network to handle additional WLAN load.
B) Problem with building dimensions
C) Problem providing sufficient PoE to 802.11b/g/n APs
D) Problem with frequency reuse planning
E) Problem procuring single radio APs
