SSCP Practice Question: A network administrator is implementing…
This SSCP practice question tests your understanding of a network administrator is implementing…. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A network administrator is implementing segmentation to limit the spread of malware. Which two technologies can achieve network segmentation? (Choose two.)
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
✓
Firewalls
Firewalls are correct because they can enforce network segmentation by controlling traffic between network segments based on security policies. By placing firewalls at segment boundaries, administrators can filter traffic using rules that inspect source/destination IP addresses, ports, and application-layer data, thereby limiting the lateral spread of malware.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse subnetting with segmentation, not realizing that subnetting alone provides no traffic filtering or isolation without a firewall or router ACL, and that VPNs are for secure tunneling, not internal network partitioning.
Detailed technical explanation
How to think about this question
Network segmentation relies on both Layer 2 (VLANs) and Layer 3/4 (firewalls) controls. VLANs use IEEE 802.1Q tagging to isolate broadcast domains on the same physical switch, preventing direct Layer 2 communication between segments. Firewalls then enforce access control lists (ACLs) or stateful inspection at segment boundaries, ensuring that only permitted traffic (e.g., specific ports or protocols) can cross, which is critical for containing worm-like malware that exploits broadcast or multicast propagation.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A security analyst at a medium-sized enterprise encounters this scenario during an investigation or architecture review. The correct answer reflects best practice for the specific threat or control described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Security exam questions test whether you can match controls to threats in context — not just recall definitions.
