The correct answer is D, identifying users with the highest number of logout events per hour, because the KQL query uses the `summarize` operator to count `DATABASE_LOGOUT` events grouped by both `UserAccount` and a `bin` on the timestamp to create hourly buckets, then sorts the results in descending order. This pattern is a classic example of using KQL to monitor Azure SQL Database activity by aggregating audit logs, and on the DP-900 exam, it tests your ability to read a Kusto query and distinguish between counting specific event types versus analyzing logins or connections. A common trap is confusing logout events with failed logins or active sessions, but the filter for `DATABASE_LOGOUT` makes the purpose clear. Remember the memory tip: "Logout count, not login amount" — the `summarize` and `count` always point to event frequency, not status.
DP-900 Practice Question: Identify considerations for relational data on Azure
This DP-900 practice question tests your understanding of identify considerations for relational data on azure. 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.
```sql
-- KQL query from Azure Monitor
AzureDiagnostics
| where ResourceProvider == "MICROSOFT.SQL"
| where Category == "SQLSecurityAuditEvents"
| where action_id_s == "DATABASE_LOGOUT"
| summarize Count = count() by user_name_s, bin(TimeGenerated, 1h)
| top 10 by Count desc
```
Refer to the exhibit. A database administrator runs the KQL query shown to monitor failed logouts? Actually, the query filters for 'DATABASE_LOGOUT' events. What is the primary purpose of this query?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "primary"
Why it matters: Asks for the main purpose or function, not a secondary benefit. Eliminate answers that describe side-effects or partial functions.

```
A
Identify users with the most failed login attempts
Why wrong: The query filters on DATABASE_LOGOUT, not login failures.
B
Determine which users are currently connected to the database
Why wrong: Current connections would require different queries, not historical logs.
C
Identify users with the highest number of logout events per hour
The query summarizes logout events by user and hour, then shows top 10.
D
Monitor the total number of database connections over time
Why wrong: The query counts logout events, not total connections.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Identify users with the highest number of logout events per hour
Option D is correct because the query counts logout events per user per hour. Option A is wrong because it counts logouts, not failed logins. Option B is wrong because it counts events, not active logins. Option C is wrong because it's not about total connections but logout events.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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 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. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
