ISC Practice Question: Systems Security Implementation Verification And Validation
You are verifying the implementation of a microsegmentation policy in a software-defined network (SDN). Which approach is most effective for validating that isolation is enforced?
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
✓
Perform ping tests between VMs in different security zones.
Validating microsegmentation requires testing lateral movement between segments that should be isolated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Inspect the physical switch port configuration.
Why it's wrong here
Microsegmentation is logical; physical switch settings do not reflect logical isolation.
- ✗
Review the cloud provider's SLA.
Why it's wrong here
An SLA is a legal document, not a technical validation of security controls.
- ✓
Perform ping tests between VMs in different security zones.
Why this is correct
Successful ping blocking between isolated zones is the most direct way to verify segmentation enforcement.
- ✗
Check the DNS records for the servers.
Why it's wrong here
DNS configuration is unrelated to network traffic isolation.
