What is a frame called that is intended for only one individual computer?
Unicast
A wireless access point is most like which other network device, in that all computers send signals through it to communicate with other computers?
Hub
What describes how devices connected to a hub use the speed at which the hub can transmit data?
Bandwidth sharing
What were some limitations of early networks that used a daisy-chain method of connecting computers? (Two answers.)
Total number of computers that could be connected
Cable length
When a frame is received, which component reads the source and destination MAC addresses, looks up the destination to determine where to send the frame, and forwards it out the correct port?
Switch
Just as a switch keeps records of MAC addresses that it has learned, so does your computer. What protocol does your computer use to learn MAC addresses?
ARP
When referring to network bandwidth, what is the basic unit of measurement?
Bits per Second
What following describes how devices connected to a switch use the speed at which the switch can transmit data?
Dedicated bandwidth
What tasks are performed by a NIC and its driver? (Three answers.)
Provides a connection to the network medium
Receives packets from the network protocol and creates frames
Adds error-checking data to the frame
Which of the following is NOT a function of a hub?
Transmits signal to the correct Port
What component of the computer provides it with a MAC address?
NIC
What command would you issue from the command prompt to test whether your computer has connectivity to the network?
Ping IP Address
What feature of a switch allows devices to effectively communicate at 200 Mbps on a 100 Mbps switch?
Full-duplex mode
Under which circumstances does a NIC allow inbound communications to pass through the interface? (Two answers.)
The destination MAC address matches the built-in MAC address.
The destination MAC address is all binary 1s. (Broadcast Frame)
How does a switch “learn” MAC addresses?
It reads the source address and keeps a record of which port the sending computer is on
A MAC address is composed of two 24-bit numbers. What does the first 24-bit number represent?
It’s the organizationally unique identifier (OUI)
A __________ frame is a message that is intended to be processed by all devices on the LAN
Broadcast
What is the purpose of an SSID?
Identifies a wireless network
What describe the function of routers? (Two answers.)
Connect Lans
Work with Packets and IP Addresses
Which of the following is NOT a reason to prefer a switch over a hub?
Switches can operate at 10 Mbps or 100 Mbps.
What is the purpose of the default route?
It’s where the router sends all packets with destinations of which it has no knowledge.
Which of the following is true of a repeater?
A. Receives frames and forwards them
B. Determines which network to send a packet
C. Receives bit signals and strengthens them
D. Has a burned-in MAC address for each port
C. Receives bit signals and strengthens them
What type of indicator lights would you find on a hub? (Three answers.)
Network Activity, Status, Collision
GIMME
This is a gimme, so good job for picking it
