The answer is to modify the SQL script to use T-SQL compatible with dedicated SQL pool. This is required because dedicated SQL pool uses a different T-SQL surface area than the serverless SQL pool, with restrictions on certain functions, table types, and distribution-specific syntax that work in serverless but fail in dedicated. On the DP-203 exam, this scenario tests your understanding of Synapse Analytics compute models and the fact that while both pools use T-SQL, dedicated pools enforce strict syntax for parallel processing and distribution, such as requiring `CREATE TABLE AS SELECT` (CTAS) instead of `SELECT INTO` in many cases. A common trap is assuming the linked service or integration runtime is the primary change, but the core difference is the SQL dialect itself. Memory tip: think “Dedicated demands distribution-aware T-SQL” — if your script uses `OPENROWSET` or external table references without proper distribution, it will fail in dedicated pool.
DP-203 Develop data processing Practice Question
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.
You are developing a data processing pipeline in Azure Synapse Analytics that uses a SQL script to transform data in a dedicated SQL pool. The pipeline currently runs in the built-in serverless pool, but you want to migrate it to a dedicated SQL pool for better performance. What must you change in the pipeline?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Modify the SQL script to use T-SQL compatible with dedicated SQL pool.
Option A is correct because dedicated SQL pool uses T-SQL with specific syntax differences from serverless SQL pool. Option B (linked service) may also need updating but is not the primary change. Option C (integration runtime) is not necessarily required if both pools are in the same workspace. Option D (data flow) is a different activity type.
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.
✗
Change the linked service from serverless to dedicated SQL pool.
Why it's wrong here
While the linked service needs updating, the SQL script itself may also need changes; the primary change is the script.
✗
Replace the SQL script with a Mapping Data Flow activity.
Why it's wrong here
Data Flow is an alternative but not required; the script can still work with modifications.
✗
Update the integration runtime to a self-hosted IR.
Why it's wrong here
Integration runtime is for connectivity, not for SQL script compatibility.
✓
Modify the SQL script to use T-SQL compatible with dedicated SQL pool.
Why this is correct
Dedicated SQL pool has a different T-SQL surface area; some functions may need to be rewritten.
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 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. NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
