DP-300 Practice Question: Plan and configure a high availability and disaster recovery environment
Which TWO are benefits of using a failover group for Azure SQL Database? (Select 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
✓
Allows the secondary database to be readable for reporting
Option A is correct because a failover group allows you to configure the secondary database as readable, enabling read-only workloads such as reporting to be offloaded to the secondary replica. Option C is correct because a failover group provides a read/write listener endpoint (e.g., <failover-group>.database.windows.net) that automatically redirects connections to the current primary after a failover, giving applications a stable connection string. Option B is not a benefit specific to failover groups; TDE is a database-level encryption feature that can be enabled independently and is not provided or extended across regions by a failover group. Option D is incorrect because failover groups do not automatically load-balance read queries between primary and secondary; read-only routing must be configured and is not automatic balancing. Option E is incorrect because Azure SQL Database failover groups use asynchronous replication, not synchronous replication, between the primary and secondary servers.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Allows the secondary database to be readable for reporting
Why this is correct
A failover group replicates databases to a secondary server that can be opened read-only, letting reporting workloads query the secondary without impacting the primary. This satisfies the requirement for an offload reporting target while retaining failover capability.
- ✗
Enables transparent data encryption (TDE) across regions
Why it's wrong here
TDE encrypts data at rest per database and is configured independently of failover groups, so cross-region TDE is not a failover-group benefit. It is tempting because failover groups do replicate databases, but encryption keys and TDE state are managed separately; TDE would be the answer if the question asked how to encrypt data at rest.
- ✓
Provides a single read/write listener endpoint for the primary database
Why this is correct
A failover group publishes read/write and read-only listener endpoints that remain constant across role changes. Applications connect to the single read/write listener, so no connection string edits are needed after a geo-failover, satisfying the stem's benefit requirement.
- ✗
Automatically balances read queries between primary and secondary
Why it's wrong here
Failover groups replicate and redirect connections; they do not load-balance read queries across replicas. Tempting because read-scaleout is a genuine Azure SQL capability, and it would be correct where the requirement is offloading reporting traffic rather than cross-region failover.
- ✗
Supports synchronous replication between primary and secondary
Why it's wrong here
Failover groups replicate asynchronously, so synchronous replication is not a benefit they provide. Synchronous replication is tempting because it guarantees zero data loss, and it is achievable within an Azure SQL Database auto-failover group only when configured for the primary and secondary in the same region.

Transparent Data Encryption
Transparent Data Encryption is a security feature that automatically encrypts data written to a database and decrypts it when read, without requiring any changes to the application.
