The correct answer is that the KQL query filters for File entities, as it explicitly specifies where EntityType == 'File'. This works because KQL (Kusto Query Language) in Microsoft 365 Defender uses the EntityType field to narrow evidence retrieval to a specific category of forensic artifacts, such as files, processes, or network connections. On the SC-900 exam, this concept tests your ability to interpret basic KQL syntax within incident investigation scenarios, often presenting a query snippet and asking which entity type is being isolated. A common trap is confusing the EntityType value with other fields like ActionType or Timestamp, so always look directly for the equality operator after EntityType. Remember the mnemonic: "File is the filter, not the filler" — when you see EntityType == 'File', the query is strictly about file evidence, not processes, network, or registry.
SC-900 Practice Question: Describe the capabilities of Microsoft security solutions
This SC-900 practice question tests your understanding of describe the capabilities of microsoft security solutions. 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.
Exhibit
Refer to the exhibit.
```kusto
AlertEvidence
| where Timestamp > ago(1h)
| where AlertId == "alert-5678"
| where EntityType == "File"
| project FileName, FilePath, SHA256
```
You are investigating an alert in Microsoft 365 Defender. The KQL query in the exhibit retrieves evidence for alert-5678. What type of entities does this query filter for?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
File entities
Option D is correct because the query filters where EntityType == 'File'. Option A is wrong because it filters for File, not Process. Option B is wrong because it filters for File, not Network. Option C is wrong because it filters for File, not Registry.
Key principle: 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 healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
