This DP-203 practice question tests your understanding of develop 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.

Refer to the exhibit. You are reviewing an ARM template snippet for an Azure Synapse Analytics workspace. The template defines an integration runtime. A colleague asks whether this integration runtime can be used to copy data from an on-premises SQL Server database to Azure Blob Storage. What should you answer?

A
No, you need an Azure integration runtime that is configured for on-premises access.
Why wrong: Azure IR cannot access on-premises sources directly.
B
Yes, because the integration runtime is self-hosted and can access on-premises data sources.
Self-hosted IR is used for on-premises/private network data sources.
C
No, you need a managed virtual network integration runtime for on-premises sources.
Why wrong: Managed VNet IR is for Azure data sources behind a VNet, not on-premises.
D
Yes, but only if the integration runtime is installed on a domain-joined machine.
Why wrong: Domain join is not a requirement; the IR only needs network access to the source.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Yes, because the integration runtime is self-hosted and can access on-premises data sources.
The ARM template snippet defines a self-hosted integration runtime, which is designed to be installed on a local machine inside the corporate network. This allows it to directly connect to on-premises SQL Server databases using native drivers (e.g., ADO.NET) and then copy data to Azure Blob Storage via the Azure cloud. Self-hosted IRs are the correct choice for hybrid data movement scenarios where the source is on-premises and the destination is cloud-based.
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
The trap here is that candidates often confuse the self-hosted IR with the Azure IR, assuming any IR can access on-premises data, but only the self-hosted IR (installed locally) can bridge the on-premises-to-cloud gap.
Detailed technical explanation
How to think about this question
Under the hood, the self-hosted integration runtime uses a Windows service that communicates with Azure Data Factory/Synapse via outbound HTTPS (port 443) to receive job instructions. It then uses the appropriate on-premises data source drivers (e.g., SQL Server Native Client) to extract data, and uploads it to Azure Blob Storage using Azure Storage REST APIs. A subtle behavior is that the self-hosted IR must be registered with a unique authentication key from the Azure portal, and it supports high availability by deploying multiple nodes behind a load balancer.
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.
TExam Day Tips
→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 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.
