The answer is outdated component. An operating system version that no longer receives security updates is classified as an outdated component because the vendor has ceased patching known vulnerabilities, leaving the system exposed to exploits that target unpatched flaws. This directly violates the principle of maintaining a secure baseline, especially for a public web server where the outdated component vulnerability creates a clear attack surface. On the Security+ SY0-701 exam, this concept tests your ability to identify configuration weaknesses in vulnerability scan reports, often appearing as a distractor against “misconfiguration” or “weak encryption.” A common trap is confusing an unsupported OS with a missing patch, but remember: an outdated component means the vendor has permanently stopped updates, not just delayed them. Memory tip: “No patches, no support, it’s an outdated component of last resort.”
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 reports that a public web server is running an operating system version that no longer receives security updates. Which issue is present?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Outdated component
An operating system version that no longer receives security updates is an outdated component. This means the vendor has ceased patching known vulnerabilities, leaving the system exposed to exploits that target unpatched flaws. In the context of a public web server, this directly violates the principle of maintaining a secure baseline and is a common finding in vulnerability scans.
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.
✗
Weak permissions
Why it's wrong here
Weak permissions involve overly broad file or access rights, not an unsupported operating system version.
✓
Outdated component
Why this is correct
An unsupported operating system is an outdated component because it no longer receives vendor security fixes.

✗
DNS poisoning
Why it's wrong here
DNS poisoning affects name resolution, which is unrelated to the server's software support lifecycle.
✗
Smishing
Why it's wrong here
Smishing is a text-message social engineering attack, which has nothing to do with server patch status.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse 'outdated component' with 'weak permissions' because both involve configuration issues, but the question specifically describes a version that no longer receives updates, which is a lifecycle/obsolescence problem, not a permissions misconfiguration.
Detailed technical explanation
How to think about this question
Under the hood, an outdated OS lacks security patches for known CVEs (Common Vulnerabilities and Exposures), such as privilege escalation or remote code execution flaws. For example, an unpatched Windows Server 2008 R2 (end-of-life in January 2020) is vulnerable to EternalBlue (MS17-010), which allows wormable SMB exploits. Real-world scenarios include ransomware like WannaCry, which specifically targeted outdated Windows systems that had not applied the MS17-010 patch.

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
An employee at a financial services firm receives an email that appears to come from the IT helpdesk, asking them to reset their password via a link. The link leads to a convincing fake portal that harvests credentials. Security teams use phishing simulations and security-awareness training to reduce this attack vector. Questions like this test whether you can identify social engineering techniques and appropriate controls.
