Full question →mediummultiple choiceObjective-mapped
An organization ingests its Palo Alto firewall logs into a custom table named 'PaloAlto_CL' in Microsoft Sentinel. A security analyst wants to create a scheduled analytics rule that triggers an incident when a single source IP is involved in more than 100 outbound connections to different destinations in 1 minute. Which KQL query and configuration would trigger the alert correctly?
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
summarize count() by SourceIP, bin(TimeGenerated,1m) and set threshold >100
This counts total connections, not distinct destinations. The requirement is for different destinations, so distinct count is needed.
B
Best answer
summarize dcount(DestinationIP) by SourceIP, bin(TimeGenerated,1m) and set threshold >100
This correctly counts distinct destination IPs per source IP per minute and triggers when that count exceeds 100.
C
Distractor review
summarize count() by DestinationIP and threshold >100
This counts total connections to each destination, ignoring source IP and time window.
D
Distractor review
summarize dcount(SourceIP) by DestinationIP, bin(TimeGenerated,1m) and threshold >100
This counts distinct source IPs per destination, which is the reverse of what is needed.
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: summarize dcount(DestinationIP) by SourceIP, bin(TimeGenerated,1m) and set threshold >100 — The rule should count distinct destination IPs per source IP per minute, not total connections. Using dcount(DestinationIP) with bin(TimeGenerated,1m) and then filtering for count > 100 is correct. Option A uses count() which counts all connections, not distinct destinations. Option C counts by destination only. Option D counts distinct sources per destination, which is the wrong direction.
