The correct answer is that Azure Database for PostgreSQL provides automated backups with point-in-time restore and supports read replicas. These are core managed features that offload administrative overhead: automated backups run without manual intervention, and point-in-time restore allows recovery to any second within the retention window, while read replicas enable scaling read-heavy workloads by offloading queries to a read-only copy. On the DP-900 exam, this question tests your understanding of what distinguishes a Platform as a Service (PaaS) database from a self-managed instance—specifically, which operational tasks are automated. A common trap is confusing PostgreSQL with a NoSQL database or assuming it only supports the community edition, but Azure Database for PostgreSQL is a relational SQL database that supports both community and enterprise editions. Memory tip: think “BACKUP + REPLICA” as the two pillars of managed PostgreSQL—backup handles disaster recovery, and replicas handle performance scaling.
DP-900 Practice Question: Identify considerations for relational data on Azure
This DP-900 practice question tests your understanding of identify considerations for 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.
Which TWO of the following are true about Azure Database for PostgreSQL? (Select TWO.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
It supports read replicas to offload read traffic.
Options B and D are correct. Azure Database for PostgreSQL is a managed service that provides automated backups and supports read replicas. Option A is incorrect because it is not a NoSQL database. Option C is incorrect because it supports both the community and enterprise editions. Option E is incorrect because it does not support cross-database queries across different servers.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✗
It only supports the open-source community edition of PostgreSQL.
Why it's wrong here
It also supports the Citus extension for distributed tables.
✗
It is a NoSQL database service.
Why it's wrong here
It is a relational database service.
✓
It supports read replicas to offload read traffic.
Why this is correct
Read replicas can be created in the same or different region.

✗
It allows cross-database queries across multiple servers.
Why it's wrong here
Cross-database queries are limited to within the same server.
✓
It provides automated backups with point-in-time restore.
Why this is correct
Automated backups are a built-in feature.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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.
