Network Interface Card (NIC) Quiz

Which of the following is NOT typically associated with transceiver problems?

• Signal degradation

• Frequent disconnections

• Stable network performance

• Data transmission errors

How many bits are in a MAC address?

• 32 bits

• 48 bits

• 64 bits

• 128 bits

What is the primary function of a hub in a network?

• To send transmissions from one port to every other port.

• To send transmissions to a single designated port.

• To filter and forward data to specific ports.

• To encrypt data before transmission.

Which statement best describes the function of a hub?

• It selectively sends data to specific devices.

• It broadcasts data to all connected devices.

• It compresses data before sending.

• It analyzes data packets.

Why might a hub cause network inefficiency?

• It encrypts all data.

• It sends data to all ports, leading to collisions.

• It compresses data, slowing down transmission.

• It stores data, causing delays.

How does a bridge affect the logical network structure?

• It divides the logical network into multiple segments.

• It maintains a single logical network while separating physical segments.

• It creates multiple logical networks.

• It has no effect on the logical network structure.

What is the effect of a bridge on collision domains?

• It combines them into one.

• It separates them.

• It eliminates them.

• It duplicates them.

What happens when a switch receives a data packet with an unknown destination MAC address?

• It drops the packet

• It broadcasts the packet to all ports

• It sends the packet back to the sender

• It stores the packet

Which of the following best describes a switch's learning process?

• It learns IP addresses

• It learns MAC addresses

• It learns data formats

• It learns port numbers

In the context of networking, what does a switch primarily connect?

• Different networks

• Devices within the same network

• Wireless devices

• Internet service providers
