Question 1 | The IEEE 802 defines Ethernet as which IEEE standard? -
A. 802.3 -
B. 802.5 -
C. 802.11 -
D. 802.9 -
E. 802.3ae -
F. 802.11b |
A1: | Answer: A. The 802.3 IEEE standard describes Ethernet and CSMA/CD. |
Question 2 | What does UTP stand for? |
A2: | 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? -
A. 45 bytes -
B. 100 bytes -
C. 48 bytes -
D. 64 bytes -
E. 12 bytes -
F. 1518 bytes |
A3: | 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? -
A. FDDI -
B. CSMA/CD -
C. CSMA -
D. RIP -
E. BGP |
A4: | 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. -
A. Full duplex -
B. Broadcast -
C. Baton -
D. Token -
E. Terabit -
F. CSMA/CD |
A5: | 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? -
A. Hub -
B. Layer 2 Switch -
C. Layer 3 Router -
D. LAN Extender -
E. Bridge |
A6: | 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? -
a. Bridge -
b. Switch -
c. Hub -
d. Router |
A7: | 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. -
A. Multicast -
B. FDDI -
C. Active monitor -
D. Ethernet -
E. MAU -
F. Token |
A8: | 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? -
A. Switch -
B. Hub -
C. Bridge -
D. Router -
E. FDDI -
F. Token Ring |
A9: | 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. -
A. Unicast -
B. Broadcast -
C. Full duplex -
D. FDDI -
E. Multicast |
A10: | Answer: B. A broadcast sends a copy of a transmission to all nodes on the network. |
