- A
Run a full antivirus scan on the server.
Why wrong: Antivirus scans rely on signature databases and may miss custom or zero-day malware, and they can be time-consuming, delaying a timely response. This is not the best first step.
- B
Check the server's running processes for unknown executables.
Reviewing running processes is a fast, direct way to identify suspicious programs that might be generating the unusual traffic. Unfamiliar processes are a classic indicator of compromise.
- C
Block all outbound traffic from the server at the firewall.
Why wrong: Blocking traffic may contain the threat but also destroys evidence of the communication pattern and could alert an attacker prematurely. Investigation should precede containment.
- D
Review the server's event logs for failed login attempts.
Why wrong: While event logs can show unauthorized access attempts, they do not directly address the current anomalous outbound traffic. This is a secondary analysis step, not the first action.
SY0-701 Security Operations Practice Question
This SY0-701 practice question tests your understanding of security operations. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 security analyst notices a sudden increase in outbound traffic from a database server that normally only communicates with internal application servers. The server is running a standard OS with no recent changes. Which of the following actions should the analyst take FIRST to determine if the server is compromised?

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
Check the server's running processes for unknown executables.
Checking the server's running processes for unknown executables is the first and most direct step to identify if an attacker has established a foothold. A sudden outbound traffic spike without recent configuration changes strongly suggests a malicious process (e.g., a reverse shell or data exfiltration tool) is running. Examining running processes allows the analyst to spot suspicious executables or command-line arguments before taking more disruptive actions like blocking traffic or running a scan.
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.
- ✗
Run a full antivirus scan on the server.
Why it's wrong here
Antivirus scans rely on signature databases and may miss custom or zero-day malware, and they can be time-consuming, delaying a timely response. This is not the best first step.
When this WOULD be correct
A security analyst notices multiple endpoints exhibiting slow performance and pop-ups, and a recent email campaign delivered a known malware strain. Running a full antivirus scan would be the first step to identify and remove the known malware across the environment.
- ✓
Check the server's running processes for unknown executables.
Why this is correct
Reviewing running processes is a fast, direct way to identify suspicious programs that might be generating the unusual traffic. Unfamiliar processes are a classic indicator of compromise.
Clue confirmation
The clue word "first" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
Block all outbound traffic from the server at the firewall.
Why it's wrong here
Blocking traffic may contain the threat but also destroys evidence of the communication pattern and could alert an attacker prematurely. Investigation should precede containment.
When this WOULD be correct
If the question asked for the BEST immediate action to prevent data exfiltration after confirming a compromise, blocking outbound traffic at the firewall would be correct.
- ✗
Review the server's event logs for failed login attempts.
Why it's wrong here
While event logs can show unauthorized access attempts, they do not directly address the current anomalous outbound traffic. This is a secondary analysis step, not the first action.
When this WOULD be correct
This would be correct if the question described a scenario where the analyst suspects a brute-force attack or credential compromise, and the first step is to identify the source of unauthorized access attempts.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The SY0-701 exam frequently reuses these exact scenarios with slightly different constraints.
✓Check the server's running processes for unknown executables.Correct answer▾
Why this is correct
Reviewing running processes is a fast, direct way to identify suspicious programs that might be generating the unusual traffic. Unfamiliar processes are a classic indicator of compromise.
✗Run a full antivirus scan on the server.Wrong answer — click to see why▾
Why this is wrong here
Running a full antivirus scan is time-consuming and may not detect sophisticated or custom malware. The immediate priority is to identify suspicious processes causing the unusual outbound traffic, which is faster and more direct.
★ When this WOULD be the correct answer
A security analyst notices multiple endpoints exhibiting slow performance and pop-ups, and a recent email campaign delivered a known malware strain. Running a full antivirus scan would be the first step to identify and remove the known malware across the environment.
Why candidates choose this
Candidates often default to antivirus scans as a standard response to potential compromise, overlooking that the immediate symptom (unusual outbound traffic) requires process investigation for a quicker assessment.
✗Block all outbound traffic from the server at the firewall.Wrong answer — click to see why▾
Why this is wrong here
Blocking all outbound traffic at the firewall would disrupt legitimate internal communications and is a reactive containment step, not a first investigative action to determine compromise.
★ When this WOULD be the correct answer
If the question asked for the BEST immediate action to prevent data exfiltration after confirming a compromise, blocking outbound traffic at the firewall would be correct.
Why candidates choose this
Candidates may think stopping suspicious traffic is the priority, but the first step is to gather evidence (processes) before taking containment actions.
✗Review the server's event logs for failed login attempts.Wrong answer — click to see why▾
Why this is wrong here
Reviewing event logs for failed login attempts is a secondary step; the immediate priority is to identify active malicious processes causing the outbound traffic spike, not historical authentication events.
★ When this WOULD be the correct answer
This would be correct if the question described a scenario where the analyst suspects a brute-force attack or credential compromise, and the first step is to identify the source of unauthorized access attempts.
Why candidates choose this
Candidates often associate compromise with unauthorized access, so they default to checking login logs, overlooking that active data exfiltration requires immediate process investigation.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often jump to blocking traffic (Option C) as a quick fix, but the FIRST action must be to gather evidence by inspecting running processes, as blocking prematurely destroys forensic data and violates the principle of 'do no harm' during incident response.
Trap categories for this question
Command / output trap
While event logs can show unauthorized access attempts, they do not directly address the current anomalous outbound traffic. This is a secondary analysis step, not the first action.
Detailed technical explanation
How to think about this question
On a standard OS like Windows Server or Linux, the 'tasklist' or 'ps aux' commands can reveal processes with unusual names, high CPU/memory usage, or network connections to external IPs. Attackers often name processes to blend in (e.g., 'svchost.exe' or 'crond'), so checking the full command line and parent process ID (PPID) is critical. In a real-world scenario, a reverse shell might use a non-standard protocol like DNS tunneling over UDP port 53, which would not be caught by a simple port-based firewall rule but would appear as a suspicious process.
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.
