True or False: Client isolation is a feature that can be enabled on WLAN access points or controllers to block wireless clients from communicating directly with other wireless clients on the same wireless VLAN.

True or False: After users have been authorized to pass through the wireless portal, VLANs and identity-based mechanisms are needed to further restrict access to network resources.

True or False: The wireless portal must be protected, and therefore an authentication solution is needed to ensure that only authorized devices and users can pass through the portal via a wireless access point (AP).

True or False: Proper network design now entails providing necessary speed while trying to maximize the number of devices connected to any single access point at the same time.

True or False: Roaming problems and interference issues will often be mitigated in advance if proper WLAN design techniques are performed and a thorough site survey is conducted.

True or False: The term all-band interference is typically associated with frequency hopping spread spectrum (FHSS) communications that usually disrupt the 802.11 communications at 2.4 GHz.

True or False: A narrowband RF signal occupies a larger frequency space and will cause a denial of service (DoS) for an entire band, such as the 2.4 GHz ISM band.

True or False: If a collision occurs or any portion of a unicast frame is corrupted, the cyclic redundancy check (CRC) will fail and the receiving 802.11 radio will not return an ACK frame to the transmitting 802.11 radio.

True or False: Unless you are using the WLAN for a real-time video conference, audio can likely take a backseat to video.

True or False: Designing a WLAN to support voice communications can also be a challenge because there are so many differences in how vendors implement their voice products.

True or False: When designing a WLAN to support voice communications, you should keep in mind that, unlike data communications, voice communications are tolerant of network delays, dropped packets, or sporadic connections.

True or False: When planning for network traffic over any type of network, wireless or wired, you need to first look at the protocols that are being implemented.

True or False: When data-oriented applications are discussed, email and web browsing are two of the most common applications that come to mind.

True or False: Although WLAN controllers typically reside on the core of the network, they can also be deployed at the access layer, usually in the form of a remote office WLAN controller.

True or False: One major disadvantage of using the traditional autonomous access point is that there is a central point of management.
