SY0-701 Threats, Vulnerabilities, and Mitigations Practice Question
This SY0-701 practice question tests your understanding of threats, vulnerabilities, and mitigations. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
Exhibit
Vulnerability scan summary:
1) Internet-facing VPN appliance
CVSS: 8.8
Exploit status: public proof-of-concept available
Exposure: reachable from the internet
Compensating controls: none
2) Internal HR file server
CVSS: 9.8
Exploit status: no public exploit yet
Exposure: reachable only from the employee VLAN
Compensating controls: segmented network and MFA for admin access
3) Lab workstation
CVSS: 10.0
Exploit status: public exploit available
Exposure: isolated lab VLAN with no routing to production
4) DMZ reporting server
CVSS: 7.5
Exploit status: public exploit available
Exposure: internet-reachable, but protected by WAF and IP allowlisting
Based on the exhibit, which issue should be remediated FIRST?
The team can only fully fix one issue today. Management wants the choice that best reduces real-world risk, not just the highest severity score.
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.

A
Internet-facing VPN appliance
This asset is externally reachable, has a known public exploit, and lacks compensating controls. That combination creates the highest immediate likelihood of compromise.
B
Internal HR file server
Why wrong: The score is high, but the server is not directly internet-exposed and has layered controls that reduce immediate attack likelihood.
C
Lab workstation
Why wrong: Although severe, the lab is isolated from production, so the business impact and likelihood are much lower than an exposed perimeter device.
D
DMZ reporting server
Why wrong: The server is exposed, but the WAF and allowlist reduce practical exploitability compared with the VPN appliance that has no compensating controls.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Internet-facing VPN appliance
The Internet-facing VPN appliance is the highest priority because it is directly exposed to untrusted networks (the Internet), making it the most likely entry point for attackers. A compromise here could lead to full network access, bypassing all other security controls, which represents the greatest real-world risk regardless of its severity score.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Internet-facing VPN appliance
Why this is correct
This asset is externally reachable, has a known public exploit, and lacks compensating controls. That combination creates the highest immediate likelihood of compromise.
Clue confirmation
The clue words "best", "first" in the question point toward this answer.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often fixate on the highest CVSS severity score (e.g., a critical vulnerability on the internal server) rather than considering the attack surface and likelihood of exploitation, which is the core of risk-based prioritization.
Detailed technical explanation
How to think about this question
A VPN appliance typically terminates IPsec or SSL/TLS tunnels and often handles authentication (e.g., RADIUS, LDAP) and encryption keys. If an attacker exploits a vulnerability in the VPN server (e.g., CVE-2023-46805 in Ivanti Connect Secure), they can bypass authentication, gain a foothold, and pivot laterally into the internal network. This is why patching Internet-facing VPNs is prioritized in real-world incident response — they are the digital front door.
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.
