EDR alerts show a finance laptop spawning an unsigned executable from %AppData%, attempting to read LSASS memory, and making outbound HTTPS connections to a rare domain. The user says they only opened a spreadsheet attachment. What is the best immediate action?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
Reboot the laptop to clear any malicious process from memory.
Rebooting may destroy volatile evidence and can allow persistence to reestablish after startup.
B
Best answer
Isolate the laptop from the network using the EDR platform.
Network isolation immediately stops outbound command-and-control traffic and reduces the chance of lateral movement. It also preserves the endpoint for later forensics better than powering it off or wiping it. Because the host is still active, isolation is the safest containment step while the team gathers volatile evidence and decides on eradication.
C
Distractor review
Run a full antivirus scan and wait for the results before taking further action.
A scan is useful later, but it is too slow to serve as the first containment action in an active compromise.
D
Distractor review
Reset the user's password and keep the laptop online for monitoring.
Password resets help if credentials are stolen, but they do not stop the compromised host from communicating externally.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.

FAQ
Questions learners often ask
What does this SY0-701 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Isolate the laptop from the network using the EDR platform. — EDR-based isolation is the best immediate response because the laptop is showing multiple signs of active malware execution and credential theft behavior. Isolating the endpoint cuts off command-and-control traffic, limits spread, and keeps the system powered on for volatile-data collection and later forensic analysis. It is a faster and safer containment step than rebooting, scanning, or only changing credentials. Why others are wrong: Rebooting can erase volatile evidence and may not remove persistence. Running a scan is useful, but it is not the fastest way to stop active malicious communications. Resetting the user's password is a good follow-up if credential theft is suspected, but it does not contain the infected endpoint itself. The host must be isolated first.
