- A
Disconnect the server from the network at the switch level.
Correct. Network isolation is a containment measure that stops the ongoing data exfiltration while preserving the server's state for later investigation. This aligns with the containment step in the NIST incident response framework.
- B
Run a comprehensive antivirus scan on the server.
Why wrong: Incorrect. Running an antivirus scan may alert the attacker and does not immediately stop the data exfiltration. Containment should occur first; scanning is part of the eradication and recovery phases.
- C
Notify the Chief Information Security Officer (CISO) of the incident.
Why wrong: Incorrect. While notification is a critical step in incident response, the immediate action should be containment to limit damage. Reporting typically occurs after initial containment and verification of the incident.
- D
Power off the server to prevent further damage.
Why wrong: Incorrect. Powering off the server may destroy volatile data (e.g., memory contents, running processes) that are vital for forensic analysis. Logical network isolation is preferred unless physical safety is at risk.
SY0-701 Security Operations Practice Question
This SY0-701 practice question tests your understanding of security operations. 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 security analyst at a financial firm detects an unusual spike in outbound network traffic from a database server that normally only communicates with internal web servers. The traffic is directed to numerous external IP addresses in various countries. According to established incident response procedures, what should be the analyst's immediate next step?
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
Disconnect the server from the network at the switch level.
Disconnecting the server at the switch level (e.g., shutting down the switch port or placing it in a quarantine VLAN) is the immediate containment step per incident response procedures. This stops the outbound data exfiltration without risking data loss or corruption that could occur from a hard power-off, and it preserves volatile memory evidence for forensic analysis.
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 confuse 'immediate containment' with 'immediate notification' or 'immediate remediation,' but the SY0-701 incident response framework prioritizes stopping the active threat (containment) over escalation or scanning.
Detailed technical explanation
How to think about this question
Under the hood, outbound traffic to numerous external IPs often indicates a C2 beacon or data exfiltration via HTTP/HTTPS or DNS tunneling. Disconnecting at the switch port (using SNMP or CLI commands like `shutdown` on the interface) immediately drops all Layer 2 connectivity, preventing further data transfer while keeping the server powered on so that memory dumps (via tools like FTK Imager or WinPmem) can capture active processes and network connections. In a real-world scenario, this containment step is critical in financial firms to meet regulatory breach notification timelines (e.g., GDPR 72-hour rule) by stopping the exfiltration before it escalates.
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.
