The correct interpretation is that the query retrieves items from an Azure Cosmos DB container where the age property exceeds 25. In Cosmos DB SQL API syntax, 'c' serves as an alias representing each individual item or document within the container, and the WHERE clause filters those items based on the condition that the numeric 'age' field is greater than 25. This Cosmos DB query interpretation tests your understanding of the SQL API’s document-model querying, a core topic on the DP-900 exam, where common traps include confusing Cosmos DB with SQL Server or assuming the query targets a table or stored procedure. Remember that Cosmos DB queries operate on schema-free JSON documents, not relational tables, so 'c' always refers to a container item. A helpful memory tip: think of 'c' as standing for "container item" — each 'c' is a single document you’re checking against the filter.
DP-900 Practice Question: Describe considerations for working with non-relational data on Azure
This DP-900 practice question tests your understanding of describe considerations for working with non-relational data on azure. 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.
Exhibit
{ "version": "1.0", "statement": "SELECT * FROM c WHERE c.age > 25" }
Refer to the exhibit. The exhibit shows a query used in Azure Cosmos DB. What is the correct interpretation of this query?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
It queries an Azure Cosmos DB container for items where the age property exceeds 25.
In Azure Cosmos DB SQL API, 'c' is an alias for each item in the container. The query retrieves all items where the 'age' property is greater than 25. Option A is wrong because it's not SQL Server. Option C is wrong because it's not filtering documents. Option D is wrong because it's not a stored procedure.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
It is a SQL Server query that selects from a table named 'c'.
Why it's wrong here
Azure Cosmos DB uses its own SQL dialect, not SQL Server.
✓
It queries an Azure Cosmos DB container for items where the age property exceeds 25.
Why this is correct
The query uses the FROM clause with alias 'c' and filters on age.

Read the scenario before looking for a memorised answer.
✗
It executes a stored procedure in Azure Cosmos DB.
Why it's wrong here
This is a SQL query, not a stored procedure call.
✗
It retrieves all documents from the Azure Cosmos DB database named 'c'.
Why it's wrong here
'c' is an alias for the container items, not the database name.
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.
