Answers to Practice Test Questions
166. C. A point-to-multipoint wireless bridge will allow you to connect all three buildings
together, tying them back to a central location. A mesh network is usually designed for
endpoints (clients) and not the interconnection of buildings. Point-to-point bridges would
allow all the buildings to connect to each other, but it would not network them together to
a central point. Autonomous wireless access points are used for endpoint connectivity and
not building-to-building connectivity.
167. B. A service set identifier (SSID) can be a maximum of 32 characters in length. The
wireless access point will associate a MAC address to the SSID so clients can associate to
the SSID. All of the other options are incorrect.
168. D. The cheapest and most effective solution you could recommend is to install a wireless
repeater. A wireless repeater will do just that: it will repeat the current wireless signal and
allow for extra distance. A wireless bridging system is used for connecting buildings or
locations where running wire is just not possible. A mesh wireless system is probably the
most expensive option, since it requires infrastructure such as a controller and lightweight
WAPs. Adding just a wireless LAN controller will not add any benefit.
169. A. A lightweight WAP requires a wireless LAN controller (WLC) to function because
all data forwarding is controlled by the WLC. A basic service set (BSS) is not a type of
wireless access point; it is a deployment of wireless. Wireless bridges allow for buildings or
locations where running cable is not possible to bridge the locations. An autonomous WAP
is a WAP that can act independently without a WLC.
170. A. A mesh wireless network will allow for coverage of the large area. A mesh network
will provide the highest bandwidth possible. An autonomous wireless network is
composed of several wireless access point, but they require direct connection to the wired
network. A point-to-multipoint wireless bridge is used for connecting buildings together
to a central point. Wireless repeaters could possibly achieve the coverage, but they would
do so at the cost of bandwidth.
171. B. Wireless LAN controllers allow trunks to be used so that multiple VLANs can be
used. Once the VLANs are accessible to the WLC, you need to create one SSID tied to
the VLAN configured for production and another SSID tied to the VLAN configured
for guests. Access control lists won’t work because they are implemented at layer 3 and
wireless signaling operates at layer 2. Dynamic VLANs are VLANs that are associated
with a host dynamically based upon authentication. Although this option would satisfy
the segmentation of traffic, it is not the simplest solution to the problem.
172. C. You can build an EtherChannel between routers and wireless controllers to obtain
more bandwidth when using router on a stick (ROAS). It is supported on certain models of
routers, such as 4000 series routers. RIP will not balance bandwidth between the wireless
controller and the router. Wireless controllers will not perform inter-VLAN routing; this
job requires a router or firewall with routing capabilities.
