The correct answer is the DNS connector using Azure Monitor Agent (AMA). This is the most appropriate data source for ingesting on-premises DNS logs into Microsoft Sentinel because the DNS connector is purpose-built to collect and parse DNS query logs directly from Windows DNS servers via the Azure Monitor Agent, capturing the full query and response fields needed to detect anomalous patterns like data exfiltration. On the SC-200 exam, this question tests your understanding of log source selection for threat hunting scenarios, often appearing as a trap where candidates confuse Azure DNS (which only covers cloud-hosted zones) or Syslog (which lacks native DNS field parsing) with the dedicated on-premises DNS connector. A common memory tip is to remember that for on-premises DNS logs, you need the DNS connector with AMA—think “DNS on-prem, AMA the stream.” This ensures you capture the rich query metadata required to spot unusual outbound queries indicative of data theft.
SC-200 Perform threat hunting Practice Question
This SC-200 practice question tests your understanding of perform threat hunting. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 threat hunter wants to identify anomalous DNS queries that may indicate data exfiltration. In Microsoft Sentinel, which data source is most appropriate for ingesting DNS logs from on-premises servers?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
DNS connector using Azure Monitor Agent (AMA)
Option C is correct because the DNS connector is designed to collect DNS query logs from Windows DNS servers using AMA. Option A is wrong because Azure DNS is for Azure-hosted zones. Option B is wrong because Syslog may not parse DNS fields natively. Option D is wrong because Windows Event Forwarding is for Windows events, not DNS logs.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Syslog connector
Why it's wrong here
Syslog can collect logs but often requires additional parsing; dedicated DNS connector is better.
✓
DNS connector using Azure Monitor Agent (AMA)
Why this is correct
The DNS connector with AMA is the recommended method for on-premises DNS logs.
Related concept
Static NAT maps one inside address to one outside address.
✗
Azure DNS connector
Why it's wrong here
Azure DNS connector is for Azure DNS zones, not on-premises servers.
✗
Windows Event Forwarding (WEF)
Why it's wrong here
WEF is for Windows security events, not DNS query logs.
Common exam traps
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.
Detailed technical explanation
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.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
