Full question →hardmultiple choiceObjective-mapped
A threat hunter in Microsoft Sentinel writes a KQL query in the Logs blade to find possible data exfiltration. The query uses the CommonSecurityLog table to look for large outbound file transfers from a specific IP address. The analyst wants to include only events where the total bytes sent in a 5-minute window exceed 100 MB. Which KQL operator combination would best achieve this?
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
Best answer
CommonSecurityLog | where SourceIp == '10.0.0.1' | summarize totalBytes = sum(BytesSent) by bin(TimeGenerated, 5m) | where totalBytes > 100000000
Correct. This groups events by 5-minute windows, sums bytes sent per window, and filters those windows exceeding 100 MB (100000000 bytes).
B
Distractor review
CommonSecurityLog | where SourceIp == '10.0.0.1' | extend bin = bin(TimeGenerated, 5m) | where BytesSent > 100000000
This filters individual events where a single BytesSent exceeds 100 MB, not the aggregate over a window. It does not sum multiple events.
C
Distractor review
CommonSecurityLog | where SourceIp == '10.0.0.1' | summarize make_list(BytesSent) by TimeGenerated | where array_length(make_list) > 100000000
make_list creates a list of values, not a sum. The where condition on array length is meaningless for byte total.
D
Distractor review
CommonSecurityLog | where SourceIp == '10.0.0.1' | project BytesSent, TimeGenerated | summarize sum(BytesSent) by bin(TimeGenerated, 5m) | where sum_BytesSent > 100000000
This is almost correct except the last where clause references 'sum_BytesSent' instead of the actual column name from summarize (which would be the function name or alias). It will cause a syntax error. The correct alias should be used in the where clause.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

FAQ
Questions learners often ask
What does this SC-200 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: CommonSecurityLog | where SourceIp == '10.0.0.1' | summarize totalBytes = sum(BytesSent) by bin(TimeGenerated, 5m) | where totalBytes > 100000000 — To aggregate data over a time window, you use the summarize operator with bin on TimeGenerated to create 5-minute buckets. Then you sum BytesSent (or similar numeric field) and filter with where on the aggregated sum. The bin function creates time intervals; summarize aggregates; where filters the results. Other options either don't aggregate correctly or use incorrect operators like make_list or project.
