- A
Exposed management service
This is the correct answer because the admin SSH service is reachable on all interfaces instead of being limited to the internal management network. That increases attack surface and allows unauthorized internet exposure if firewall rules are weak or missing. The problem is the service placement and exposure, not the SSH protocol itself.
- B
Default credentials
Why wrong: Default credentials are a separate issue involving unchanged vendor usernames or passwords. The scan result here says nothing about the account password.
- C
Outdated component
Why wrong: An outdated component would mean the software version is end-of-life or missing patches. The clue here is network exposure, not software age.
- D
Weak permissions
Why wrong: Weak permissions usually refer to file, folder, or object access controls. The problem in this question is that the management service is reachable too broadly.
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.
A vulnerability scan finds an administrative SSH service listening on 0.0.0.0 on a server that should be managed only from the internal network. What is the main security issue?
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
Exposed management service
The SSH service binding to 0.0.0.0 means it is listening on all network interfaces, including external-facing ones. This exposes the administrative management interface to potentially untrusted networks, violating the principle of least privilege and increasing the attack surface. The main security issue is that a service intended for internal management only is accessible from outside the trusted internal network.
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 may focus on the SSH service itself (e.g., thinking of weak passwords or outdated versions) rather than recognizing that the binding to 0.0.0.0 is a network exposure misconfiguration.
Detailed technical explanation
How to think about this question
Binding to 0.0.0.0 (INADDR_ANY) causes the SSH daemon to accept connections on all IPv4 interfaces, including public-facing ones. In Linux, this is typically configured in /etc/ssh/sshd_config with the 'ListenAddress 0.0.0.0' directive; changing it to a specific internal IP (e.g., 192.168.1.10) restricts access to that subnet. A real-world scenario is a misconfigured cloud server where SSH is left open to the internet, leading to brute-force attacks or unauthorized access.
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 team runs a vulnerability scan on a web application and discovers an unpatched SQL injection flaw. The team prioritises remediation by CVSS score — critical flaws are patched within 24 hours, high within 7 days. Questions like this test whether you understand vulnerability management processes, scanning tools, and remediation prioritisation.
