- A
Run a full antivirus scan first and leave the workstation online so the user can keep working.
Why wrong: A scan may help later, but it does not stop active suspicious communication immediately. Leaving the host online risks further spread or data loss.
- B
Isolate the workstation through the EDR platform and preserve logs and volatile evidence for investigation.
Encoded PowerShell combined with outbound beaconing is a strong indicator of active malicious behavior. Isolating the endpoint through EDR contains the incident while preserving the host’s state for analysis. This approach is better than pulling the plug because it reduces attacker activity without unnecessarily destroying volatile evidence. The analyst can then collect logs, memory, and process details before remediation or reimaging.
- C
Power off the workstation immediately to ensure the malicious process stops.
Why wrong: Powering off stops execution, but it also destroys volatile evidence that can be critical for determining what happened and whether other systems are involved.
- D
Create a permanent firewall rule that allows the unfamiliar IP address so you can observe more traffic.
Why wrong: Allowing suspicious traffic increases risk and does not provide a safe or reliable investigative method. Containment should come before observation of hostile connections.
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.
An EDR console alerts that powershell.exe launched with an encoded command on a finance workstation, and a minute later the host begins making repeated outbound connections to an unfamiliar IP address. What is the best initial response?

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
Isolate the workstation through the EDR platform and preserve logs and volatile evidence for investigation.
Option B is correct because isolating the workstation via the EDR platform stops the immediate threat (the malicious outbound connections) while preserving volatile evidence (e.g., running processes, network connections, memory contents) and logs for forensic analysis. This aligns with the incident response principle of containment before eradication, and EDR isolation typically uses a host-based firewall rule to block all traffic except to the EDR management server, ensuring the host remains accessible for investigation.
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 (isolation) with eradication (antivirus scan) or evidence preservation (shutdown), but the SY0-701 emphasizes that isolation via EDR is the best initial response because it stops the threat without destroying volatile data.
Detailed technical explanation
How to think about this question
EDR isolation works by deploying a host-based firewall rule that drops all inbound and outbound traffic except traffic to the EDR management server (often over a specific port like 443 or a custom port). This preserves the ability to remotely collect forensic artifacts (e.g., memory dumps via WinPmem, process lists, registry hives) while cutting off the attacker's C2 channel. In real-world incidents, encoded PowerShell commands often leverage base64-encoded scripts to download and execute payloads in memory, bypassing traditional file-based detection.
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.

Same concept, more angles
1 more ways this is tested on SY0-701
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A SOC analyst confirms that a workstation is encrypting local files and attempting SMB connections to nearby hosts. The user is still logged in, and the business wants to limit spread without destroying evidence. What is the best immediate action?
medium- A.Power the workstation off immediately and leave it in place
- ✓ B.Quarantine the workstation from the network using EDR or switch port containment
- C.Run a full antivirus scan while the workstation remains connected
- D.Wipe and reimage the workstation from a standard build image
Why B: Option B is correct because quarantining the workstation via EDR or switch port containment immediately stops the SMB-based lateral movement and further encryption of network shares, while preserving the volatile evidence (memory, running processes, encryption keys) for forensic analysis. This aligns with the business requirement to limit spread without destroying evidence, as powering off or reimaging would lose critical forensic data.
