The correct next step is to treat the alert as potentially malicious and check endpoint and proxy logs for more context. This is because the regular, persistent outbound connection to an unknown external IP address every 15 minutes is a classic signature of beaconing traffic analysis, often indicating malware establishing command-and-control (C2) communication. The suspicious timing—after hours and while the user is on vacation—further rules out benign scheduled tasks, making it critical to verify the traffic’s nature through deeper log inspection. On the Security+ SY0-701 exam, this scenario tests your ability to triage SIEM alerts by distinguishing beaconing from legitimate updates, a common trap where candidates might dismiss it as a false positive due to the user’s absence. Remember the memory tip: “Beaconing beats business hours”—if the traffic persists when no one is working, treat it as a C2 red flag.
SY0-701 Security Operations Practice Question
This SY0-701 practice question tests your understanding of security operations. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 SIEM alert shows a workstation connecting to the same unknown internet address every 15 minutes, even after business hours. The device belongs to an employee who is on vacation. What is the best next step for the analyst?
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.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Treat the alert as potentially malicious and check endpoint and proxy logs for more context.
Option B is correct because the alert describes a persistent outbound connection to an unknown external IP address at regular intervals, which is a classic indicator of beaconing behavior often associated with malware command-and-control (C2) traffic. The fact that the connection occurs after business hours and the workstation's user is on vacation increases suspicion, as legitimate scheduled tasks or updates would typically not run under those conditions. Checking endpoint and proxy logs provides the necessary context to determine if the traffic is benign (e.g., a misconfigured service) or malicious (e.g., C2 communication).
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.
✗
Dismiss the alert because periodic connections are always normal for workstations.
Why it's wrong here
Regular timing can be normal, but unknown destinations still need verification.
✓
Treat the alert as potentially malicious and check endpoint and proxy logs for more context.
Why this is correct
Unknown periodic outbound traffic can indicate beaconing, so additional log review is the right next step.
Clue confirmation
The clue word "best" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Immediately delete the workstation account from the directory service.
Why it's wrong here
Deleting accounts is destructive and not an appropriate first response.
✗
Shut down the entire office network until the analyst can review the alert.
Why it's wrong here
This would be highly disruptive and is not justified by a single alert.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may assume periodic connections are always benign (e.g., Windows Update or NTP sync) and dismiss the alert, failing to recognize that the regularity, unknown destination, and user-on-vacation context are red flags for malicious C2 activity.
Detailed technical explanation
How to think about this question
Beaconing traffic often uses HTTP/HTTPS on non-standard ports or mimics legitimate API calls to evade detection; a SIEM alert triggered by a firewall or proxy log showing a connection every 15 minutes to a single IP with no DNS resolution suggests a hardcoded IP in malware. In a real-world scenario, this could be a backdoor like Cobalt Strike's HTTP beacon, which uses a configurable sleep time (e.g., 60000 ms) to blend in with normal traffic. Analysts should correlate with Windows Event Logs (e.g., 4688 for process creation) to identify the parent process initiating the connection.

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 analyst at a medium-sized enterprise encounters this scenario during an investigation or architecture review. The correct answer reflects best practice for the specific threat or control described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Security exam questions test whether you can match controls to threats in context — not just recall definitions.
