Motorola Solutions Design WLan Solutions Sample Questions:
In radio frequency transmission the term Modulation Coding Scheme (MCS) is defined by which of the following?
- A. A multiplexing technique that uses orthogonal codes in place of X.509 digital certificates for message validation.
- B. The combination of digital modulation method and a forward error correction mechanism.
- C. A set of AES/CCMP cipher modes which assure integrity of an OFDM transmission.
- D. The use of an encryption algorithm to securely code a modulated signal before transmission.
The centralized WLAN is actually a hub-and-spoke architecture that requires backhaul of virtually all wireless traffic to a controller (the hub). This hub-and-spoke architecture can create costly scalability and performance issues for$02.11n networks. Motorola's WiNG 5 WLAN 802.11n capable distributed architecture is designed to overcome these challenges.
Some of the challenges are listed below:
Which of the following is another Hub and Spoke challenge that is addressed by the WiNG 5 architecture?
- A. Extended seamless roaming from mobile devices with no latency
- B. Eliminates the need for a controller in large networks
- C. Dependent networks can only scale to the processing limitations of the controller and available bandwidth of the network.
- D. Non Peak Application bandwidth down time
Which of the following statements are CORRECT regarding IEEE 802.11 Deauthentication frames (Select TWO)?
- A. Can be issued by either a client station or AP
- B. Can only be issued by a client station device
- C. Occurs when user logs off the wireless network
- D. Can only be issued by an AP
- E. Can be refused by either client station or AP
Your customer has a requirement that the APs used in the design are capable of 802.11n. Which of the following APs does NOT meet this requirement?
- A. AP650
- B. AP5131
- C. AP7131
- D. AP6511
