- A
Block the external IP address at the firewall.
Why wrong: Blocking the IP is a containment action, but it should be taken after confirming the incident and assessing potential impact. Doing it first might disrupt legitimate services and does not help in gathering initial evidence.
- B
Review the user's login and activity logs.
Reviewing logs is the correct first step. It allows the analyst to verify the alert, see if the user was logged in, identify the process responsible for the transfer, and gather details necessary for informed decision-making.
- C
Contact the user to inquire about the transfer.
Why wrong: Contacting the user prematurely could tip off a malicious insider or create confusion. The investigation should first rely on technical evidence to avoid compromising the integrity of the response.
- D
Restore the workstation from a known good backup.
Why wrong: Restoring from backup would erase volatile data and potential evidence. This step is only appropriate after thorough forensic analysis and containment, not as the first action.
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 in a SOC receives an alert indicating that a large volume of data was transferred from a user's workstation to an external IP address at 2:00 AM. The analyst suspects a data exfiltration attack. According to incident response best practices, what should the analyst do FIRST?
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 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
Review the user's login and activity logs.
Option B is correct because, in incident response, the first step is to gather evidence and understand the scope of the incident. Reviewing the user's login and activity logs (e.g., Windows Event Logs, authentication logs, and process creation logs) allows the analyst to verify if the user was actually logged in at 2:00 AM, identify any anomalous behavior (e.g., use of unauthorized tools or unusual file access patterns), and determine whether the data transfer was initiated by the user or by malware. This aligns with the NIST SP 800-61 incident response lifecycle, specifically the identification and analysis phase, where initial triage focuses on log review before taking containment actions.
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.
- ✗
Block the external IP address at the firewall.
Why it's wrong here
Blocking the IP is a containment action, but it should be taken after confirming the incident and assessing potential impact. Doing it first might disrupt legitimate services and does not help in gathering initial evidence.
When this WOULD be correct
This option would be correct if the question stated that the analyst has already confirmed the data exfiltration is occurring in real-time and immediate containment is required to prevent further data loss, such as in a scenario where the alert is verified and the external IP is known malicious.
- ✓
Review the user's login and activity logs.
Why this is correct
Reviewing logs is the correct first step. It allows the analyst to verify the alert, see if the user was logged in, identify the process responsible for the transfer, and gather details necessary for informed decision-making.
Clue confirmation
The clue words "best", "first" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
Contact the user to inquire about the transfer.
Why it's wrong here
Contacting the user prematurely could tip off a malicious insider or create confusion. The investigation should first rely on technical evidence to avoid compromising the integrity of the response.
When this WOULD be correct
If the question stated that the transfer was flagged during business hours and the user is available, and the analyst needs to quickly verify if the transfer was authorized (e.g., a legitimate large file upload), then contacting the user first would be appropriate to avoid unnecessary escalation.
- ✗
Restore the workstation from a known good backup.
Why it's wrong here
Restoring from backup would erase volatile data and potential evidence. This step is only appropriate after thorough forensic analysis and containment, not as the first action.
When this WOULD be correct
If the question stated that the workstation was confirmed compromised (e.g., via forensic analysis) and the priority is to remove malware and restore normal operations, then restoring from a known good backup would be the correct first step.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The SY0-701 exam frequently reuses these exact scenarios with slightly different constraints.
✓Review the user's login and activity logs.Correct answer▾
Why this is correct
Reviewing logs is the correct first step. It allows the analyst to verify the alert, see if the user was logged in, identify the process responsible for the transfer, and gather details necessary for informed decision-making.
✗Block the external IP address at the firewall.Wrong answer — click to see why▾
Why this is wrong here
Blocking the external IP at the firewall is a containment step that should be taken after verifying the alert is a true positive. The first step is to gather more information to confirm the incident, not to take immediate action that could disrupt legitimate traffic.
★ When this WOULD be the correct answer
This option would be correct if the question stated that the analyst has already confirmed the data exfiltration is occurring in real-time and immediate containment is required to prevent further data loss, such as in a scenario where the alert is verified and the external IP is known malicious.
Why candidates choose this
Candidates may think that stopping the data transfer immediately is the top priority, but they overlook the need for verification first, as per incident response frameworks like NIST SP 800-61.
✗Contact the user to inquire about the transfer.Wrong answer — click to see why▾
Why this is wrong here
Contacting the user immediately may alert a potential insider threat or disrupt forensic preservation; the analyst should first gather objective evidence from logs to confirm the incident before involving personnel.
★ When this WOULD be the correct answer
If the question stated that the transfer was flagged during business hours and the user is available, and the analyst needs to quickly verify if the transfer was authorized (e.g., a legitimate large file upload), then contacting the user first would be appropriate to avoid unnecessary escalation.
Why candidates choose this
Candidates often think that asking the user is the fastest way to clarify the situation, but they overlook the risk of tipping off a malicious insider and the need for evidence-based investigation first.
✗Restore the workstation from a known good backup.Wrong answer — click to see why▾
Why this is wrong here
Restoring from backup is a containment/recovery step that occurs after the incident has been confirmed and analyzed; it is premature before verifying the alert and gathering evidence.
★ When this WOULD be the correct answer
If the question stated that the workstation was confirmed compromised (e.g., via forensic analysis) and the priority is to remove malware and restore normal operations, then restoring from a known good backup would be the correct first step.
Why candidates choose this
Candidates may think that restoring from backup quickly stops data loss and removes any malicious software, but they overlook the need to first confirm the incident and preserve evidence.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often jump to immediate containment (blocking the IP) or recovery (restoring from backup) without first verifying the alert through log analysis, which is a fundamental incident response principle emphasized in the SY0-701 exam.

Detailed technical explanation
How to think about this question
Under the hood, the analyst should examine Windows Event ID 4624 (logon) and 4634 (logoff) to confirm the user's session, along with Event ID 4688 (process creation) to see if a file transfer tool like FTP, SCP, or a custom script was executed. Additionally, network flow logs (e.g., NetFlow or Zeek logs) can correlate the data transfer volume with specific processes, while Sysmon logs (Event ID 3 for network connections) provide granular details on the source process and destination IP. In a real-world scenario, an analyst might discover that the user's account was compromised via a phishing attack, and the logs would show a remote logon from an unusual IP address, indicating the attacker used stolen credentials to exfiltrate data.
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.
