DP-900 Practice Question: Describe considerations for working with non-relational data on Azure
This DP-900 practice question tests your understanding of describe considerations for working with non-relational data on azure. 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.
A company uses Azure Cosmos DB with the SQL API. They need to implement a data partitioning strategy to optimize query performance and avoid hot partitions. Which THREE practices should they follow?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use a synthetic partition key if natural keys are not suitable
Choosing a high-cardinality partition key (option A) distributes data evenly. Using a synthetic partition key (option C) can combine multiple attributes for better distribution. Avoiding monotonically increasing keys (option D) prevents hot partitions. Option B (using the same partition key for all items) is incorrect for large datasets. Option E (keeping partition key values very small) is not a primary consideration.
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.
✗
Use the same partition key for all items
Why it's wrong here
This would put all data in one partition, causing a hot partition.
✓
Use a synthetic partition key if natural keys are not suitable
Why this is correct
Synthetic keys can improve distribution when natural keys have low cardinality.
Related concept
Static NAT maps one inside address to one outside address.
Monotonically increasing keys cause hot partitions on the last partition.
Related concept
Static NAT maps one inside address to one outside address.
✗
Keep partition key values as small as possible
Why it's wrong here
Size of partition key is less important than cardinality and distribution.
✓
Choose a partition key with high cardinality
Why this is correct
High cardinality ensures even distribution across partitions.
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.
