- A
Remotely isolate the device through the EDR console while keeping it powered on.
EDR isolation is the best containment action because it stops most network communication while preserving the device state for investigation. Keeping the endpoint powered on maintains access to volatile evidence and avoids unnecessary disruption to disk contents or running processes. This is especially useful when the user is remote, because it can contain the threat quickly without requiring physical access or a full shutdown that would erase useful forensic data.
- B
Ask the user to uninstall the EDR agent and reboot the laptop.
Why wrong: Removing the agent weakens visibility and can help malware evade detection or persistence controls.
- C
Wait until after the presentation and then begin containment.
Why wrong: Delaying containment gives a suspected attacker more time to move laterally, exfiltrate data, or maintain access.
- D
Email the user asking them to close the browser and log out of their accounts.
Why wrong: User action alone is unreliable and does not stop malicious processes or network activity already underway.
Quick Answer
The correct containment action is to remotely isolate the device through the EDR console while keeping it powered on. This works because EDR isolation applies a host-based firewall rule that drops all network traffic except to the EDR management server, immediately blocking the suspicious process from exfiltrating browser credentials or contacting the rare command-and-control domain. On the Security+ SY0-701 exam, this scenario tests your understanding of remote laptop containment for credential theft, where the key challenge is balancing security with business continuity—the user still needs the laptop online for a presentation. A common trap is choosing to shut down or disconnect the laptop, which would disrupt local productivity and potentially destroy volatile evidence. Remember the mnemonic "Isolate, Don't Terminate": isolation blocks network paths while preserving local operations, making it the ideal response when credential theft is detected on a remote device.
SY0-701 Security Operations Practice Question
This SY0-701 practice question tests your understanding of security operations. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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.
EDR alerts on a remote laptop show a suspicious process attempting to dump browser credentials and then contacting a rare domain. The user is in another time zone and still needs the laptop online for a presentation later today. What containment action is best?

Correct answer & explanation
Remotely isolate the device through the EDR console while keeping it powered on.
Remotely isolating the device through the EDR console is the best containment action because it immediately blocks all network communication to and from the laptop while keeping it powered on and running. This prevents the suspicious process from exfiltrating browser credentials or communicating with the rare command-and-control domain, yet allows the user to continue using local applications for the presentation later today. EDR isolation typically works by applying a host-based firewall rule that drops all traffic except to the EDR management server, ensuring the threat is contained without disrupting local productivity.
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 may choose to wait until after the presentation (Option C) due to business continuity concerns, failing to recognize that immediate containment via network isolation can preserve both security and productivity.
Detailed technical explanation
How to think about this question
EDR isolation typically leverages Windows Filtering Platform (WFP) or a kernel-level network filter to block all inbound and outbound traffic except traffic to the EDR management server (often via a specific IP or port). This is more effective than disabling the network adapter because it preserves the ability to receive remote commands and updates from the security team. In real-world scenarios, attackers often use living-off-the-land binaries (LOLBins) like PowerShell or rundll32 to exfiltrate data, and isolation stops these at the network layer without requiring process termination.
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.
