💡 Hint

Common Mistakes

Choosing 'ignore' or 'disconnect' because they sound like actions but do not fit management.

Software-defined networking (SDN) centralizes control, allowing administrators to manage network devices easily from one place.

2fill in blank

medium

Complete the sentence to describe how SDN improves network flexibility.

Computer Networks

SDN separates the [1] plane from the data plane, enabling easier network configuration.

Acontrol

Bhardware

Cpower

Duser

Attempts:

💡 Hint

Common Mistakes

Confusing control plane with hardware or user plane.

SDN separates the control plane (which decides where traffic is sent) from the data plane (which forwards traffic), making networks more flexible.

3fill in blank

hard

Fix the error in the sentence about SDN benefits.

Computer Networks

SDN makes networks less [1] by centralizing control and automating tasks.

Asecure

Bslow

Ccomplex

Dflexible

Attempts:

3 left

💡 Hint

Common Mistakes

Choosing 'slow' or 'secure' which do not fit the context of reducing complexity.

SDN reduces network complexity by centralizing control and automating management tasks.

4fill in blank

hard

Fill both blanks to complete the explanation of SDN advantages.

Computer Networks

SDN uses [1] software to [2] network behavior dynamically.

Drag options to blanks, or click blank then click option'

Acentralized

Bhardware

Ccontrol

Dstatic

Attempts:

3 left

💡 Hint

Common Mistakes

Mixing hardware with software or choosing static instead of control.

SDN uses centralized software to control network behavior dynamically, allowing quick changes and automation.

5fill in blank

hard

Fill all three blanks to describe how SDN benefits network management.

Computer Networks

With SDN, network [1] is separated from [2], allowing [3] and automation.

Drag options to blanks, or click blank then click option'

Acontrol

Bhardware

Ccentralized management

Duser access

Attempts:

3 left

💡 Hint

Common Mistakes

Confusing user access with control or hardware.

SDN separates network control from hardware, enabling centralized management and automation for easier network operation.
