NCTI IV ch 11
Which of the following statements are true concerning Ethernet networks? (Choose two.)
Ethernet can use thicknet, thinnet, or twisted pair cable at the Physical Layer.
Media access control (MAC) frames are transmitted across the physical media.
What is the most widely installed local area network (LAN) technology?
Ethernet
What is the primary reason an Ethernet network interface card (NIC) transmits a jamming
message?
To warn other stations that a collision has been detected.
According to the Ethernet 5/4/3 rule, how many 10Base2 segments may have nodes attached?
3
Which Ethernet frame format includes a length field in the media access control (MAC) header?
IEEE 802.3
What is the purpose of the frame check sequence (FCS) field? (Choose two)
To check the Ethernet frame for errors using a cyclic redundancy check (CRC).
To ensure the Ethernet frame does not get processed if an error has occurred.
Where are Ethernet frames processed?
By the network interface card (NIC) at the Data Link Layer
What does an Ethernet frame addressed with a "1" as the first bit of destination media access
control (MAC) address do?
It allows all frames to be multicast to a select group of nodes.
The network interface card (NIC) in an Ethernet node receives from the Internet protocol (IP) a
packet 12 bytes long. What must the NIC do in order to prepare the packet for transmission
across the physical network?
, Add padding, a header and a trailer.
We have an expert-written solution to this problem!
What layer of software is normally loaded on the network interface card (NIC)?
Data Link Layer
What is the preamble used for?
To synchronize Ethernet network interface cards (NIC) so the bits that make up the frames are
received correctly.
How is Fast Ethernet similar to standard Ethernet?
The same frame format is used.
Cat 5E cabling can be used for both.
Star configurations are used in both types
A small company's chief technology officer (CTO) wants to upgrade their existing network to
Fast Ethernet. The existing network consists of the following:• 10/100 Network interface cards
(NIC) in the server and workstations• 10/100 Hubs• Category 3 and 5E cabling• A 10/100
routerWhich component must be upgraded to support Fast Ethernet?
The Category 3 cabling
What is the difference between the frame formats of 10 Mbps Ethernet and 100 Mbps Ethernet?
The 10 Mbps Ethernet frame is exactly the same and contains the same fields as the 100 Mbps
frame
What is the maximum cable length for 100BaseTx Ethernet?
100m
Gigabit Ethernet uses a different frame format than 10 Mbps Ethernet and Fast Ethernet. True
or False?
False

Which of the following is a Gigabit Ethernet specification for copper cable?
1000BaseCX
