• a) Few Kbps to Mbps

• b) Several Mbps

• c) Gbps

• d) Terabits per second (Tbps)

Network systems are built from which components?

• a) Software only

• b) Hardware only

• c) Both hardware and software

• d) Operating systems only

What is the primary purpose of network protocols?

• Establishing physical connections

• Defining the type of processors used

• Providing specialized support for embedded systems

• Achieving reliable communication between devices

Network virtualization aims to:

• Consolidate multiple physical networks

• Create hardware-based virtual networks only

  Limit network functionality to a single network server

  Increase the number of network protocols

• Limit network functionality to a single network server

• Increase the number of network protocols

Which type of network system would be most suitable for connecting computers within a local network?

• Routers

• Switches

• Bridges

• Gateways

Standardized network protocols provide a common language for network devices, enabling computers to communicate with each other effectively.

• TRUE

• FALSE

What do network protocols NOT define in the implementation of data communication?

• The size of memory in the devices

• The methods with which data units are encoded for transmission

• The mechanisms to detect transmission errors

• The methods for retransmission of data in case of errors

Which type of network virtualization uses network-like functionality in software containers on a single network server, enabling VMs to exchange data on a host without using an external network?

• External network virtualization

• Software-defined networking (SDN)

• Internal network virtualization

• Physical network virtualization
