Exam Prep Practice Questions


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?

  • A. Unknown twisted pair

  • B. Unusual twisted pair

  • C. Unshielded twisted pair

  • D. Usual token protocol

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.
