The answer is to isolate the workstation from the network and begin incident triage. This is the correct first response to malware outbound connections because it immediately cuts off potential command-and-control (C2) communication, preventing the attacker from issuing further instructions or exfiltrating data, while also stopping lateral movement to other hosts. On the Security+ SY0-701 exam, this scenario tests your understanding of the containment phase in the incident response process, where stopping the spread of a threat takes priority over deeper analysis or remediation. A common trap is to jump to scanning or deleting the file, but that can destroy volatile evidence like active network connections and memory artifacts. Remember the containment-first mantra: isolate before investigate, and for this exam, think of the mnemonic “C2 Cut” — cut the connection to cut the command.
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 alert shows a user workstation launching an unfamiliar executable from the Downloads folder and then making repeated outbound connections to an IP address in another country. What is the best first response by the security team?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
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 from the network and begin incident triage
Option B is correct because isolating the workstation from the network immediately stops the potential command-and-control (C2) communication and prevents lateral movement, which is the priority first response in incident triage. The EDR alert indicates a suspicious executable from the Downloads folder making repeated outbound connections to a foreign IP, which strongly suggests malware or a trojan. Isolating the host preserves volatile evidence (e.g., memory, network connections) for forensic analysis while containing the threat.
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.
✗
Wait for more alerts before taking any action to avoid disrupting the user
Why it's wrong here
Delaying action allows a possible compromise to continue, increasing risk to the endpoint and network.
✓
Isolate the workstation from the network and begin incident triage
Why this is correct
This contains the suspected threat quickly while preserving enough evidence for triage and next steps.
Clue confirmation
The clue words "best", "first" in the question point toward this answer.

✗
Immediately reinstall the operating system without collecting evidence
Why it's wrong here
Reimaging too early can destroy useful evidence and makes it harder to understand what happened.
✗
Disable the user's account in the directory service and close the ticket
Why it's wrong here
Account disablement may be useful later, but it does not stop malware already running on the host.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse incident response phases (e.g., jumping to eradication or recovery before containment) or think that disabling the user account is sufficient, when in fact the running process must be contained first to stop active network communication.
Detailed technical explanation
How to think about this question
Under the hood, the EDR likely detected the executable via behavioral analysis (e.g., process creation from a non-standard path like Downloads, followed by repeated TCP SYN packets to a high-risk IP). Isolating the workstation can be done via network access control (NAC) or by disabling the virtual switch port, which drops all Layer 2/3 traffic while preserving the host's state for memory acquisition (e.g., using FTK Imager or Volatility). In real-world scenarios, such as a BumbleBee or IcedID infection, the first outbound connection often establishes a C2 channel; immediate isolation can prevent encryption or lateral movement via SMB or RDP.

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.
