- A
Wrap the data flow in a Try-Catch activity in the pipeline.
Why wrong: Mapping Data Flows do not have try-catch; you handle errors within the data flow.
- B
Set the data flow's error handling to 'Abort on error' to stop processing on first failure.
Why wrong: Aborting is not graceful; it stops the entire pipeline.
- C
Enable schema drift on the source to automatically handle data type mismatches.
Why wrong: Schema drift handles new columns, not conversion errors.
- D
Configure the sink transformation to allow errors and log error rows to a separate file.
Sink can be configured to continue on error and write error rows to a file.
- E
Use a Conditional Split transformation to separate rows that cause errors based on a condition.
Conditional split allows routing error rows to a separate sink for logging.
DP-203 Develop data processing Practice Question
This DP-203 practice question tests your understanding of develop data processing. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 designing a data processing pipeline in Azure Data Factory that uses a Mapping Data Flow. You need to handle errors gracefully, such as when a row fails to convert a column value. Which TWO actions should you take? (Choose two.)
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
Configure the sink transformation to allow errors and log error rows to a separate file.
Options A and D are correct. Option A: Using a conditional split to route error rows is a common pattern. Option D: Configuring the sink to allow errors and logging them ensures fault tolerance. Option B is wrong because try-catch is not available in Mapping Data Flows. Option C is wrong because aborting the activity is not graceful. Option E is wrong because schema drift does not handle conversion errors.
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.
- ✗
Wrap the data flow in a Try-Catch activity in the pipeline.
Why it's wrong here
Mapping Data Flows do not have try-catch; you handle errors within the data flow.
- ✗
Set the data flow's error handling to 'Abort on error' to stop processing on first failure.
Why it's wrong here
Aborting is not graceful; it stops the entire pipeline.
- ✗
Enable schema drift on the source to automatically handle data type mismatches.
Why it's wrong here
Schema drift handles new columns, not conversion errors.
- ✓
Configure the sink transformation to allow errors and log error rows to a separate file.
Why this is correct
Sink can be configured to continue on error and write error rows to a file.
Related concept
Static NAT maps one inside address to one outside address.
- ✓
Use a Conditional Split transformation to separate rows that cause errors based on a condition.
Why this is correct
Conditional split allows routing error rows to a separate sink for logging.
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.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related DP-203 NAT questions on configuration and troubleshooting.
