
1. An 802.11 wireless network name is which
type of address? (Choose all that apply.)
A. BSSID
B. MAC address
C. IP address
D. SSID
E. Extended service set identifier

2. Topologies that require an access point.



3. The 802.11 standard defines which
medium to be used in a distribution system
(DS)?
A. 802.3 Ethernet
B. 802.15
C. 802.5 token ring
D. Star-bus topology
E. None of the above


4. A Wireless Personal Area Network WPAN is
used for close proximity networking.
There are two common technologies used in
WPAN’s they are:
◦ Bluetooth
◦ ZigBee
Remember these are just used BY WPAN’s, the actual
topology is a Wireless Personal Area Network WPAN.

5. Support for roaming is required under the
802.11 standard. Which 802.11 service set
may allow for roaming?
A. ESS
B. Basicservice set
C. Co-located APs
D. IBSS
E. Spread spectrum service set

6. The size of the Basic Coverage Area is
determined by a combination of these things:
◦ Antenna Gain
◦ Transmission Power
◦ Indoor/Outdoor surroundings



7. What is the default configuration mode
that allows an AP radio to operate in a basic
service set?
A. Scanner
B. Repeater
C. Root
D. Access
E. Non-root

8. Peer to Peer communications. We
commonly know them as ad-hoc networks,
but it’s technical name is an Independent
Basic Service Set or IBSS. So IBSS is it’s
technical name, but in the book it’s also
referred to as ad-hoc or peer to peer. So
remember all 3.

9. STAs operating in Infrastructure mode may
communicate in which of the following scenarios?
(Choose all that apply.)
A. 802.11 frame exchanges with other STAs via
an AP
B. 802.11 frame exchanges with an AP in scanner
mode
C. 802.11 frame peer-to-peer exchanges directly
with other STAs
D. Upper-layer frame exchanges with network
devices on the DSM
E. All of the above

10. Topologies defined by 802.11 standard:
◦ Basic Service Set
◦ Extended Service Set
◦ Independent Basic Service Set (ad-hoc, or Peer-topeer)

11. Which wireless topology provides citywide
wireless coverage?
A. WMAN
B. WLAN
C. WPAN
D. WAN
E. WWAN


12. What is a Basic Service Set Identifier? The
BSSID is the MAC address of the access points
wireless card.
Remember that MAC address’ reside that
layer 2, or the Data-Link layer, of the OSI
model.



13. The basic service set identifier address
can be found in which topologies? (Choose all
that apply.)
A. FHSS
B. IBSS
C. ESS
D. DSSS
E. BSS



14. What are some of the limits of 802.11?
The 802.11 WILL scale from personal WPAN,
to Metropolitan WMAN.
They WILL NOT scale to a Wide Area Network
or WWAN. They just cannot cover that large of
an area, something like that would be a
cellular network.

15. Which wired network hardware devices do
access points most resemble? (Choose all that
apply.)
A. Switch
B. Node
C. Hub
D. Router
E. Server

16. Normally an access point is ran in root
mode, there are however some non-standard
modes to run an AP in:
◦ Scanner Mode
◦ Bridge Mode
◦ Repeater Mode


17. A network consisting of clients and two
or more access points connected by an 802.3
Ethernet backbone is one example of which
802.11 topology? (Choose all that apply.)
A. ESS
B. Basic service set
C. Extended service set
D. IBSS
E. Ethernet service set

18. A Wireless Distribution System (WDS) can
allow different clients and different AP’s to
communicate together.






19. What components make up a distribution
system? (Choose all that apply.)
A. DSSS
B. Distribution system services
C. DSM
D. DSSS
E. Intrusion Detection System


20. The 802.11 standard really only defines
the Wireless Local Area Network (WLAN).
The hardware can however be easily applied
to many other network topologies.
