DP-203 Practice Question: Secure, monitor, and optimize data storage and data processing
This DP-203 practice question tests your understanding of secure, monitor, and optimize data storage and data processing. 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.
You are a data engineer at Northwind Traders. You have an Azure Synapse Analytics workspace with dedicated SQL pools. You need to monitor query performance to identify slow-running queries and understand resource consumption. The solution must provide historical data for the last 30 days and allow alerting when queries exceed a certain duration. You also need to export the data to a Log Analytics workspace for correlation with other metrics. What should you use?
Enable Diagnostic Settings for the dedicated SQL pool to send logs to Azure Storage, and query DMVs for historical data.
Why wrong: DMVs don't retain 30 days of history.
B
Use Azure Storage Analytics to analyze logs from the storage account backing the SQL pool.
Why wrong: Storage Analytics is for storage logs, not SQL.
C
Enable Diagnostic Settings to stream SQL pool metrics and logs to a Log Analytics workspace, then create alert rules and use KQL queries for historical analysis.
Provides historical data and alerting.
D
Configure SQL Server Query Store and export data to Azure Blob Storage using elastic query.
Why wrong: Query Store does not integrate with Log Analytics.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable Diagnostic Settings to stream SQL pool metrics and logs to a Log Analytics workspace, then create alert rules and use KQL queries for historical analysis.
Option B is correct: Azure Monitor diagnostic settings can send Synapse SQL pool logs and metrics to Log Analytics. Then you can create alerts and run queries over historical data. Option A is incorrect: Dynamic Management Views (DMVs) only provide current state, not historical 30-day data. Option C is incorrect: Query Store retains data for a limited time and doesn't integrate natively with Log Analytics. Option D is incorrect: Azure Storage Analytics is for storage accounts, not Synapse SQL.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Related concept
Static NAT maps one inside address to one outside address.
✗
Configure SQL Server Query Store and export data to Azure Blob Storage using elastic query.
Why it's wrong here
Query Store does not integrate with Log Analytics.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
