The answer is that the server’s slow performance and crashes are most likely caused by the lack of a restart for 180 days combined with pending updates. This is because Windows Server 2016, especially when acting as a domain controller and file server, accumulates memory leaks and resource exhaustion over prolonged uptime, while pending updates often contain critical performance fixes and stability patches that cannot take effect without a reboot. On the Systems Security Certified Practitioner SSCP exam, this scenario tests your understanding of basic system maintenance and the impact of deferred updates on availability, a core domain in operational security. A common trap is to blame malware or a specific failing service, but the event log’s Service Control Manager errors (Event ID 7000) are a red herring—they often result from services timing out due to overall system sluggishness, not a root cause. Memory tip: “Reboot to refresh—updates need a restart to do their part.”
SSCP Systems and Application Security Practice Question
This SSCP practice question tests your understanding of systems and application security. 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 small business uses a single Windows Server 2016 machine that also acts as a domain controller, file server, and runs a custom application for inventory management. The server recently exhibited slow performance and frequent crashes. The system administrator runs antivirus and finds no malware. The event log shows several 'Event ID 7000' errors from the Service Control Manager, indicating certain services failed to start. The administrator also notices that the server has not been restarted in 180 days and has several pending updates. What is the most likely cause of the performance issues?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The server has not been restarted for an extended period and has pending updates.
Option D is correct because pending updates often include bug fixes and performance improvements; the lack of restarts may lead to memory leaks or resource exhaustion. Option A is incorrect because there is no indication of resource exhaustion from a specific service. Option B is incorrect because the antivirus found no malware. Option C is incorrect because a fragmented hard drive would not cause service start failures.
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.
✗
A rootkit infection that the antivirus failed to detect.
Why it's wrong here
Rootkits are stealthy, but the antivirus scan would likely detect common rootkits.
✓
The server has not been restarted for an extended period and has pending updates.
Why this is correct
Lack of restarts can lead to resource exhaustion, and pending updates may address performance bugs.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
A heavily fragmented hard drive.
Why it's wrong here
Fragmentation affects file access speed but does not cause service start failures.
✗
A memory leak in the custom application.
Why it's wrong here
While possible, the event log shows service start failures, not memory leaks.

TExam Day Tips
→Underline the problem statement mentally.
→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.
