DP-203 Design and implement data storage Practice Question
This DP-203 practice question tests your understanding of design and implement data storage. 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.
Which THREE considerations should be evaluated when designing a partitioning strategy for a large fact table in Azure Synapse Dedicated SQL Pool?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Align partition boundaries with distribution key
Option A is correct because aligning partition boundaries with the distribution key in Azure Synapse Dedicated SQL Pool ensures that data movement during partition switching or merging is minimized, as each distribution contains its own set of partitions. This alignment avoids cross-distribution data transfers, which can significantly improve performance and maintainability of large fact tables.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Align partition boundaries with distribution key
Why this is correct
Prevents data movement.

Read the scenario before looking for a memorised answer.
✗
Use hash distribution for all fact tables
Why it's wrong here
Distribution strategy, not partitioning.
✓
Ensure partition elimination is possible in queries
Why this is correct
Improves query performance.

✓
Limit the number of partitions to fewer than 60
Why this is correct
Too many partitions hurt performance.

✗
Choose a partition column with high cardinality
Why it's wrong here
High cardinality is for distribution, not partitioning.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse partition column cardinality with distribution key cardinality, assuming high cardinality is always beneficial, but for partitioning, low cardinality is required to avoid creating too many small partitions that hurt performance.
Detailed technical explanation
How to think about this question
In Azure Synapse Dedicated SQL Pool, each distribution is essentially a shard with its own set of partitions, and partition elimination works per distribution. When partition boundaries align with the distribution key, operations like partition switching can be executed locally within each distribution without requiring data movement across distributions, which is critical for maintaining SLAs in large-scale data warehousing. A real-world scenario is loading daily sales data: aligning partition boundaries with a date-based distribution key allows seamless partition switching without redistributing data.
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 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. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
