Full question →hardmultiple choiceObjective-mapped
A multinational e-commerce company uses Azure SQL Database active geo-replication to replicate a critical inventory database to a secondary region. During a regional outage, the application automatically fails over to the secondary database. After the primary region recovers, the administrator wants to make the original primary the main database again without losing any data modifications made on the secondary during the outage. What should the administrator do?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
Drop the geo-replication relationship, then recreate the secondary from the current primary.
This would discard the secondary's data and restart replication with data loss.
B
Distractor review
Perform a forced failover to switch back to the original primary.
A forced failover may cause data loss because it does not synchronize pending changes.
C
Best answer
Initiate a planned failover to switch back to the original primary.
A planned failover (graceful failover) synchronizes all data between replicas before switching roles, ensuring zero data loss.
D
Distractor review
Delete the secondary database and restore the original primary from a backup taken before the outage.
This would lose all transactions that occurred during the outage.
Common exam trap
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.
Technical deep dive
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.

Question 1
A data engineer needs to process streaming data from IoT devices and store the results in Azure Data Lake Storage for long-term analytics. The data must be processed in near real-time to detect anomalies and trigger alerts. Which Azure service should the engineer use for stream processing?
Question 2
A data engineer needs to query data stored in CSV files in Azure Data Lake Storage Gen2 using T-SQL in Azure Synapse Analytics, without loading the data into the database. Which feature should they use?
Question 3
A data engineer needs to process raw clickstream data from multiple websites that is stored in Azure Blob Storage as JSON files. The processing must run automatically every hour, transform the data into a structured format for reporting, and handle schema changes in the source data without manual intervention. Which Azure service should be used?
Question 4
A data engineer is designing a data lake architecture in Azure. They plan to first ingest raw data from various sources into a landing zone in Azure Data Lake Storage Gen2. Then they will clean, validate, and deduplicate that data in a second zone. Finally, they will create aggregated, business-ready datasets in a third zone for analysts. This layered approach is known as which architecture?
Question 5
A data engineer needs to transform large datasets stored in Azure Data Lake Storage Gen2 using Python and Apache Spark. They want a serverless compute option that automatically scales and requires no cluster management. Which Azure service should they use?
Question 6
A company collects customer feedback forms. Each form contains always-present fields like CustomerID and SubmissionDate, but also a free-text Comments field and optional fields like Rating or ProductCategory that vary between forms. How should this data be classified?
FAQ
Questions learners often ask
What does this DP-900 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Initiate a planned failover to switch back to the original primary. — After an unplanned failover, the original primary becomes a secondary. To switch back without data loss, a planned failover (graceful failover) should be initiated. This synchronizes all data between the current primary (original secondary) and the original primary before swapping roles. Other options either drop data (removing replication, forced failover, or restoring backup) or cause data loss.
