- A
Configure a lifecycle management policy on the Table Storage account to move data to Cool tier after 30 days.
Why wrong: Table Storage does not support tiering policies; Blob Storage does.
- B
Store all data in Azure SQL Database and use index maintenance to improve query performance.
Why wrong: SQL Database is expensive and not necessary for simple key-value data.
- C
Migrate the data to Azure Cosmos DB and use Time-to-Live (TTL) to expire old data.
Why wrong: This does not address cost minimization for rarely accessed data; Cosmos DB is more expensive.
- D
Move data older than 30 days to Azure Blob Storage Cool tier and use an Azure Data Factory pipeline to copy data back to Table Storage when requested.
This optimizes cost by using Cool tier for rarely accessed data and maintains availability within 24 hours.
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.
A company stores IoT sensor data in Azure Table Storage. The data is accessed frequently for the first 30 days, then rarely. You need to minimize storage costs while ensuring data is available for queries within 24 hours of a request. What should you implement?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"first"Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
Clue:
"minimum / minimize"Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Move data older than 30 days to Azure Blob Storage Cool tier and use an Azure Data Factory pipeline to copy data back to Table Storage when requested.
Azure Table Storage does not natively support lifecycle management policies like Blob Storage does. Moving the data to Azure Storage with lifecycle management (via Azure Data Factory or AzCopy) is the correct approach. Option A is wrong because Azure Table Storage does not have automatic tiering like Blob Storage. Option B is wrong because Azure Cosmos DB is more expensive and not necessary. Option D is wrong because Azure SQL Database is a relational option not suited for this scenario.
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.
- ✗
Configure a lifecycle management policy on the Table Storage account to move data to Cool tier after 30 days.
Why it's wrong here
Table Storage does not support tiering policies; Blob Storage does.
- ✗
Store all data in Azure SQL Database and use index maintenance to improve query performance.
Why it's wrong here
SQL Database is expensive and not necessary for simple key-value data.
- ✗
Migrate the data to Azure Cosmos DB and use Time-to-Live (TTL) to expire old data.
Why it's wrong here
This does not address cost minimization for rarely accessed data; Cosmos DB is more expensive.
- ✓
Move data older than 30 days to Azure Blob Storage Cool tier and use an Azure Data Factory pipeline to copy data back to Table Storage when requested.
Why this is correct
This optimizes cost by using Cool tier for rarely accessed data and maintains availability within 24 hours.
Clue confirmation
The clue words "first", "minimum / minimize" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.
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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
