CCNA 1 – Module 6/7 Exam Answers

1. Which of the following are specified by IEEE standards as sublayers of the OSI data link layer? (Choose two.)
• Logical Link Control
• Logical Layer Control
• Media Access Control
• Logical Link Communication
• Media Access Communication
• Physical Access Communication

2.

Refer to the exhibit. Host A is communicating with host F. What happens to a frame sent from host A to host F as it travels over the Ethernet segments?
• The frame format is modified as it passes through each switch.
• The frame format remains the same across each Ethernet segment.
• The frame format is modified as the media speed changed at switch B and switch E.
• The frame format is modified as the media material changes between copper and fiber at switch C and switch D.

3. In which two layers of the OSI model does Ethernet function? (Choose two.)
• application
• session
• transport
• network
• data link
• physical

4. Where does the MAC address originate?
• DHCP server database
• configured by the administrator
• burned into ROM on the NIC card
• network configuration on the computer
• included in the creation of the processor chip

5. At what layer of the OSI model does a MAC address reside?
• 1
• 2
• 3
• 4
• 7

6. A router has an Ethernet, Token Ring, serial, and ISDN interface. Which interfaces will have a MAC address?
• serial and ISDN interfaces
• Ethernet and Token Ring interfaces
• Ethernet and ISDN interfaces
• Token Ring and serial interfaces

7. Which two devices can provide full-duplex Ethernet connections? (Choose two.)
• hub
• modem
• repeater
• NIC
• Layer 2 switch

8.

Refer to the exhibit. The small office network shown in the exhibit consists of four computers connected through a hub. Which configuration would cause collisions and errors on the network?
• autonegotiation
• FastEthernet
• peer-to-peer shared resources
• administratively configured full duplex

9.

Refer to the exhibit. The switch and workstation are administratively configured for full-duplex operation. Which statement accurately reflects the operation of this link?
• No collisions will occur on this link.
• Only one of the devices can transmit at a time.
• The switch will have priority for transmitting data.
• The devices will default back to half duplex if excessive collisions occur.

10. What are three functions of a NIC in a PC? (Choose three.)
• A NIC connects the PC to the network media.
• A NIC detects collisions on the Ethernet segment.

• A NIC checks the formatting of data before it is transmitted.
• A NIC passes the contents of selected frames to the upper OSI layers.
• A NIC acknowledges and retransmits data that was not received properly.
• A NIC discards frames when the destination IP address does not match the local host.

11. In an Ethernet LAN, how does the NIC know when it can transmit data?
• An Ethernet NIC transmits data as soon as the frame is received.
• An Ethernet NIC transmits data as soon as the NIC receives a token.
• An Ethernet NIC transmits data when it senses a collision.
• An Ethernet NIC transmits data after listening for the absence of a signal on the media.

12.

Refer to the exhibit. All hosts are in listen mode. Host 1 and Host 4 both transmit data at the same time. How do the hosts respond on the network? (Choose two.)
• Hosts 1 and 4 may be operating full duplex so no collision will exist.
• The hub will block the port connected to Host 4 to prevent a collision.
• After the end of the jam signal, Hosts 1, 2, 3, and 4 invoke a backoff algorithm.
• When the four hosts detect the collision, Hosts 1, 2, 3, and 4 generate a jam signal.
• Hosts 1 and 4 are assigned shorter backoff values to provide them priority to access the media.
• If a host has data to transmit after the backoff period of that host, the host checks to determine if the line is idle, before transmitting.

13. Which statement describes how CSMA/CD on an Ethernet segment manages the retransmission of frames after a collision occurs?
• The first device to detect the collision has the priority for retransmission.
• The device with the lowest MAC address determines the retransmission priority.
• The devices on the network segment hold an election for priority to retransmit data
• The devices transmitting when the collision occurs DO NOT have priority for retransmission.

14. What is the maximum distance that 10BASE-T will transmit data before signal attenuation affects the data delivery?
• 100 meters
• 185 meters
• 300 meters
• 500 meters

15. Which of the following are Fast Ethernet technologies? (Choose two.)
• 100BASE-5
• 100BASE2
• 1000BASE-F
• 100BASE-FX
• 100BASE-TX

16. At which OSI layer do the differences between standard Ethernet, Fast Ethernet and Gigabit Ethernet occur?
• physical layer
• data link layer
• network layer
• transport layer

17. How does 1000BASE-T use the UTP wire pairs to accomplish transmission?
• two pairs are used to transmit and two pairs are used to receive
• one pair is used to transmit, one pair is used to receive, one pair is used for clocking, and one pair is used for error correction
• all four pairs are used in parallel by both hosts to transmit and receive simultaneously
• two pairs of wires are used as in 10BASE-T and 100BASE-TX

18. Which statements describe Gigabit Ethernet technology? (Choose two.)
• operates at 100 Mbps
• typically used for backbone cabling
• requires shielded twisted-pair cabling
• can be implemented over copper and fiber
• primarily used between workstations option

19. Which media types can be used in an implementation of a 10BASE-T network? (Choose three.)
• Category 5 UTP
• Category 5e UTP
• Category 3 UTP

• coaxial cable
• multi-mode fiber
• single mode fiber

20. Which of the following Ethernet technologies are considered legacy Ethernet? (Choose three.)
• 10BASE2
• 10BASE5
• 10BASE-T

• 100BASE-T
• 100BASE-FX
• 100BASE-TX
