Exam Prep Practice Questions
Question 1
The IEEE 802 defines Ethernet as which IEEE standard?
-
802.3
-
802.5
-
802.11
-
802.9
-
802.3ae
-
802.11b
Answer: A. The 802.3 IEEE standard describes Ethernet and CSMA/CD.
Question 2
What does UTP stand for?
-
Unknown twisted pair
-
Unusual twisted pair
-
Unshielded twisted pair
-
Usual token protocol
Answer: C. UTP, or unshielded twisted pair, is the term used to describe Category 3, 5, 6, and 7 cabling made without shielding.
Question 3
What is the minimum frame size for an Ethernet Frame?
-
45 bytes
-
100 bytes
-
48 bytes
-
64 bytes
-
12 bytes
-
1518 bytes
Answer: D. The minimum frame size for Ethernet is 64 bytes.
Question 4
Ethernet LAN technology employs which protocol to detect collisions in LAN transmissions?
-
FDDI
-
CSMA/CD
-
CSMA
-
RIP
-
BGP
Answers: B. Ethernet technology employs the Carrier Sense Multiple Access with Collision Detection protocol (CSMA/CD).
Question 5
Token Ring uses a _______ to pass a stream of data in a network.
-
Full duplex
-
Broadcast
-
Baton
-
Token
-
Terabit
-
CSMA/CD
Answer: D. Token Ring uses a token to circulate the ring, and stations wait for the token in order to transmit data. If the token is busy, stations must wait until the token is free.
Question 6
When segmenting a LAN, what device reduces the size of a broadcast domain?
-
Hub
-
Layer 2 Switch
-
Layer 3 Router
-
LAN Extender
-
Bridge
Answer: C. A router can reduce the size of the broadcast domain because routers create a smaller network, thus creating a smaller broadcast domain. Some switches use Virtual LANs at Layer 3 to create smaller broadcast domains as well.
Question 7
When segmenting a LAN, what device cannot be used to reduce the collision domain?
-
Bridge
-
Switch
-
Hub
-
Router
Answer: C. A hub can't reduce the size of the collision domain because hubs use a shared environment.
Question 8
Token Ring employs this mechanism for detecting and compensating for network faults and multiple tokens in a Token Ring network.
-
Multicast
-
FDDI
-
Active monitor
-
Ethernet
-
MAU
-
Token
Answer: C. Active monitor is the mechanism for detecting and compensating network faults. One station is selected to be active monitor.
Question 9
If used to segment the LAN, what device decreases the size of segments and can connect several LANs?
-
Switch
-
Hub
-
Bridge
-
Router
-
FDDI
-
Token Ring
Answer: C. A bridge will decrease the size of the segment and can connect several LANs.
Question 10
A _______ copies and sends a transmission to every destination node on the network.
-
Unicast
-
Broadcast
-
Full duplex
-
FDDI
-
Multicast
Answer: B. A broadcast sends a copy of a transmission to all nodes on the network.
