SSCP Practice Question: Is the primary purpose of network segmentation?
Which of the following is the primary purpose of network segmentation?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enhance security by isolating sensitive systems
The primary purpose of network segmentation is to enhance security by isolating sensitive systems and limiting lateral movement of threats. Option D is correct. Option A is incorrect because segmentation does not directly increase bandwidth. Option B is incorrect; while performance may improve due to reduced broadcast domains, security is the primary goal. Option C is incorrect because segmentation can complicate IP address management. Option E is incorrect because segmentation often increases hardware cost.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Increase bandwidth
Why it's wrong here
Increasing bandwidth is not a purpose of network segmentation; segmentation focuses on traffic isolation and security, not bandwidth.
- ✗
Improve network performance
Why it's wrong here
Although segmentation can reduce broadcast domains and improve performance, that is a secondary benefit; the primary purpose is security.
- ✗
Simplify IP address management
Why it's wrong here
Network segmentation can complicate IP address management due to additional subnets and routing, so simplification is not the purpose.
- ✓
Enhance security by isolating sensitive systems
Why this is correct
Correct. Network segmentation isolates sensitive systems, containing breaches and limiting lateral movement.
- ✗
Reduce hardware cost
Why it's wrong here
Segmentation often adds hardware cost for firewalls, routers, or VLAN configuration, so reducing cost is not a purpose.
