Motorola Solutions Design WLan Solutions Sample Questions:

1. During the execution of the site survey, your assistant informs you that the data rate is decreasing as he moves away from the AP. How can this behavior be best explained?

A) It is not normal and indicates a hardware problem.
B) It is a normal function of Dynamic Rate Shifting.
C) It is normal and usually caused by other stations transmitting.
D) It is not normal and must be a function of multipath.

2. An existing customer site within an industrial park is using dual band capable VoWLAN devices on the 802.11b/g/n frequency band. The customer uses an RFS4000 cluster (active/standby) with single radio AP650's running WiNGv5.x code. Up until recently, the devices have been performing as expected. This week, however, the VoWLAN devices have started having issues related to voice quality and establishing connections. After some investigation, you determine that a neighbor has recently installed a brand new wireless system. What can this customer do to best address the issues related to voice quality and establishing connections?

A) Explain to the neighbor that they need to change their settings or lower their AP power output because it is illegal for their network to interfere with a currently installed wireless network.
B) Increase the power output on their own AP's in order to 'drown out' the neighbors signals.
C) Purchase ADSP and use the air termination feature to constantly jam the neighbors APs as rogues.
D) Configure the APs and VoWLAN devices to work on the 802.11a/n frequency band.

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 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.
B) 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.
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 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.

4. Motorola's "Site Survivability'' concept gives the wireless network the power of wireless computing on the edge. What does this mean?

A) If your T1/E1 link fails, Access Points or controllers can automatically switch over to a 3g network backhaul
B) With direct routing, QoS, security, and mobility services on the Access Point, the network keeps running even if there is a problem with the wireless controller or the wired network
C) Application-aware smart RF adjusts power and channel to provide best coverage if there is RF interference or a neighboring AP is having a problem.
D) RFID traffic load-balancing with rate limiting and bandwidth management

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