Total questions: 12
Worksheet time: 6mins
Why is Ethernet important in network communication?
It prevents data collisions and improves speed and efficiency.
It allows for wireless connectivity.
It encrypts data for security.
It reduces the cost of network hardware.
What does the LLC sublayer do in the Data Link Layer?
Controls hardware addressing
Talks to Layer 3 and identifies protocols
Manages physical connections
Encrypts data
What does a switch do when it receives a frame with a known destination MAC address?
It forwards the frame to the correct port.
It floods the frame to all ports.
It discards the frame.
It sends the frame back to the source.
During the learning phase, what information does a switch store in its MAC table?
Destination MAC and port
Source MAC and port
IP address and port
Frame size and port
For what purpose is a broadcast MAC address typically used?
Sending data to a single device
ARP requests and initial device discovery
Encrypting data packets
Establishing a secure connection
What is the modern default communication method in networks?
Half-Duplex
Full-Duplex
No-Duplex
Single-Duplex
Which device operates at the Data Link Layer to forward frames based on MAC addresses?
Repeater
Router
Switch
Firewall
What happens if two devices transmit data simultaneously on a shared Ethernet network?
The data is automatically merged.
Only one device's data is delivered.
The network ignores both transmissions.
The data collides and both devices must retransmit.
Which address type is used to send a frame to all devices on a local network segment?
Loopback address
Multicast address
Broadcast address
Unicast address
Which layer of the OSI model is responsible for MAC addressing and frame forwarding?
Transport Layer
Data Link Layer
Physical Layer
Network Layer
What action does a switch take when it receives a frame with an unknown destination MAC address?
It discards the frame.
It forwards the frame to all ports except the source port.
It sends the frame back to the sender.
It encrypts the frame before forwarding.
Which of the following is a unique identifier assigned to network interfaces for communications at the Data Link Layer?
Default gateway
IP address
MAC address
Subnet mask
