- A
Disconnect the server from the network immediately.
Why wrong: While isolating a compromised system is sometimes necessary, doing so immediately without investigation may destroy volatile forensic evidence, disrupt legitimate services, and prevent understanding of the attacker's methods. Disconnection should be considered only after initial analysis indicates a clear threat.
- B
Block the IP address at the perimeter firewall.
Why wrong: Blocking the IP address addresses the symptom but not the root cause. The malware or process causing the connection remains active on the server, and the attacker may simply switch to a different IP. This step is premature without knowing what is causing the connection.
- C
Review the server's process list and logs to identify the source.
This is the correct first step. By examining the process list and logs (e.g., system, firewall, and application logs), the analyst can determine the specific process or service responsible for the outbound connection, assess whether it is malicious, and gather evidence for further investigation or escalation.
- D
Escalate the incident to the incident response team.
Why wrong: Escalation is appropriate once the analyst has performed initial triage and can provide the incident response team with specific findings, such as the process causing the connection and relevant log entries. Immediate escalation without investigation may delay resolution and lack necessary context.
SY0-701 Security Operations Practice Question
This SY0-701 practice question tests your understanding of security operations. Compare every option against the stated constraints before choosing — the best answer satisfies all requirements, not just the most obvious one. 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 detects an encrypted outbound connection from a web server to an unknown IP address. The connection is persistent and occurs every 5 minutes. What is the MOST appropriate first step for the analyst to take?

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
Review the server's process list and logs to identify the source.
Option C is correct because the first step in investigating an unknown encrypted outbound connection is to identify the process or service responsible for initiating it. Reviewing the server's process list and logs allows the analyst to determine whether the connection is legitimate (e.g., a scheduled update or backup) or malicious (e.g., a beacon from implanted malware). Without this visibility, actions like blocking or disconnecting could disrupt legitimate services or alert an attacker prematurely.
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.
- ✗
Disconnect the server from the network immediately.
Why it's wrong here
While isolating a compromised system is sometimes necessary, doing so immediately without investigation may destroy volatile forensic evidence, disrupt legitimate services, and prevent understanding of the attacker's methods. Disconnection should be considered only after initial analysis indicates a clear threat.
When this WOULD be correct
If the encrypted outbound connection is confirmed as active data exfiltration of sensitive data and the server is isolated from critical systems, immediate disconnection may be justified to prevent further data loss, especially when containment is prioritized over forensic preservation.
- ✗
Block the IP address at the perimeter firewall.
Why it's wrong here
Blocking the IP address addresses the symptom but not the root cause. The malware or process causing the connection remains active on the server, and the attacker may simply switch to a different IP. This step is premature without knowing what is causing the connection.
When this WOULD be correct
This option would be correct if the question stated that the analyst has already confirmed the connection is malicious (e.g., via threat intelligence or sandbox analysis) and the immediate priority is to contain the threat by blocking communication with a known command-and-control server.
- ✓
Review the server's process list and logs to identify the source.
Why this is correct
This is the correct first step. By examining the process list and logs (e.g., system, firewall, and application logs), the analyst can determine the specific process or service responsible for the outbound connection, assess whether it is malicious, and gather evidence for further investigation or escalation.

Escalate the incident to the incident response team.
Why it's wrong here
Escalation is appropriate once the analyst has performed initial triage and can provide the incident response team with specific findings, such as the process causing the connection and relevant log entries. Immediate escalation without investigation may delay resolution and lack necessary context.
When this WOULD be correct
This would be correct if the analyst had already identified malicious activity (e.g., confirmed malware or data exfiltration) and the incident exceeded their authority or required specialized response resources.
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.

Why this is correct
This is the correct first step. By examining the process list and logs (e.g., system, firewall, and application logs), the analyst can determine the specific process or service responsible for the outbound connection, assess whether it is malicious, and gather evidence for further investigation or escalation.
✗Disconnect the server from the network immediately.Wrong answer — click to see why▾
Why this is wrong here
Disconnecting the server immediately could destroy volatile evidence (e.g., running processes, memory contents) needed to identify the source of the encrypted connection, and may cause unnecessary service disruption without understanding the threat.
★ When this WOULD be the correct answer
If the encrypted outbound connection is confirmed as active data exfiltration of sensitive data and the server is isolated from critical systems, immediate disconnection may be justified to prevent further data loss, especially when containment is prioritized over forensic preservation.
Why candidates choose this
Candidates may believe that stopping the connection immediately is the safest action, not realizing that preserving evidence for analysis is typically the first step in incident response unless there is an immediate threat to life or critical data loss.
✗Block the IP address at the perimeter firewall.Wrong answer — click to see why▾
Why this is wrong here
Blocking the IP address at the perimeter firewall is premature without first identifying the source and nature of the connection. The connection could be legitimate (e.g., a scheduled update or backup), and blocking it might disrupt operations or alert an attacker without gathering evidence.
★ When this WOULD be the correct answer
This option would be correct if the question stated that the analyst has already confirmed the connection is malicious (e.g., via threat intelligence or sandbox analysis) and the immediate priority is to contain the threat by blocking communication with a known command-and-control server.
Why candidates choose this
Candidates may think blocking the IP is a quick and effective containment step, but they overlook the need for investigation first to avoid false positives and preserve forensic evidence.
✗Escalate the incident to the incident response team.Wrong answer — click to see why▾
Why this is wrong here
In this scenario, the analyst has not yet identified the source of the encrypted connection. Escalating without initial investigation would bypass necessary evidence gathering and could delay containment.
★ When this WOULD be the correct answer
This would be correct if the analyst had already identified malicious activity (e.g., confirmed malware or data exfiltration) and the incident exceeded their authority or required specialized response resources.
Why candidates choose this
Candidates may believe that any suspicious encrypted outbound connection warrants immediate escalation to incident response, overlooking the need for initial triage and evidence collection.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often jump to containment (disconnect or block) without first performing local analysis, failing to recognize that the initial step in incident response is always identification and scoping before containment.
Detailed technical explanation
How to think about this question
Encrypted outbound connections (e.g., HTTPS on port 443, or custom TLS on non-standard ports) are commonly used by command-and-control (C2) malware to blend with legitimate traffic. Tools like netstat, lsof, or Sysinternals TCPView can reveal the PID and associated executable, while Windows Event Logs (Event ID 5156) or Linux auditd logs can trace the connection to a specific process. In a real-world scenario, a persistent 5-minute beacon could indicate a C2 heartbeat, but it might also be a legitimate service health check or a misconfigured application update.
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 SOC analyst notices unusual lateral movement in the network at 2 AM. The IR playbook dictates: identify and contain (isolate the affected machine), then eradicate (remove the malware), then recover (restore from backup), then document. Skipping containment before eradication risks the attacker regaining access. Questions like this test the sequence and rationale of incident response phases.
