Wireless LAN Topologies Team 3 (Garrett and Terrance)
Types of Addresses • 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
802.11 Topologies • 2. Topologies that require an access point.
DS Medium • 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
Wireless Topologies • 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.
802.11 Service Set • 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
Basic Service Area Coverage • 6. The size of the Basic Coverage Area is determined by a combination of these things: • Antenna Gain • Transmission Power • Indoor/Outdoor surroundings
Basic Service Set • 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
Topologies Involving Station • 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.
Station • 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
Standard 802.11 Topologies • 10. Topologies defined by 802.11 standard: • Basic Service Set • Extended Service Set • Independent Basic Service Set (ad-hoc, or Peer-to-peer)
Wireless Topologies • 11. Which wireless topology provides citywide wireless coverage? • A. WMAN • B. WLAN • C. WPAN • D. WAN • E. WWAN
Basic Service Set Identifier • 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.
BSS Identifier Addresses • 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
Wireless Networking Scale • 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.
Access Points • 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
Nonstandard Modes • 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
802.11 Topologies • 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
AP Communication • 18. A Wireless Distribution System (WDS) can allow different clients and different AP’s to communicate together.
DS Components • 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
Standard 802.11 Topologies • 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.
