Quick Answer
The answer is fast provisioning of additional read replicas and support for up to 100 TB of database storage. These two benefits are core to the Hyperscale service tier because its distributed architecture separates compute from storage, using a shared disk model with page servers that allow storage to scale near-instantly without downtime. On the Microsoft Azure Database Administrator Associate DP-300 exam, this question tests your understanding of how Hyperscale differs from General Purpose and Business Critical tiers, which both cap at 4 TB. A common trap is confusing Hyperscale’s read scale-out capability with Business Critical’s built-in replicas—Hyperscale lets you add read replicas in minutes, not hours, making it ideal for heavy read workloads. Remember the memory tip: “Hyperscale = Huge storage + Hot replicas,” where the “H” stands for both 100 TB and high-speed replica provisioning.
This DP-300 practice question tests your understanding of plan and implement data platform resources. 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 benefits does the Hyperscale service tier of Azure SQL Database provide?
Built-in in-memory OLTP support.
Why wrong: In-memory OLTP is not a key feature of Hyperscale.
Zone-redundant configuration by default.
Why wrong: Zone redundancy is optional, not default.
Up to 100 TB of database storage.
Hyperscale provides large storage capacity.
Fast provisioning of additional read replicas.
Hyperscale can scale out replicas quickly.
Zero data loss in all scenarios.
Why wrong: Hyperscale uses asynchronous replication.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Up to 100 TB of database storage.
Option C is correct because the Hyperscale service tier of Azure SQL Database supports up to 100 TB of database storage, which is significantly larger than the 4 TB limit of the General Purpose tier and the 4 TB limit of the Business Critical tier. This massive storage capacity is achieved through a distributed architecture where data is stored in page servers with a shared disk model, allowing near-instantaneous scaling of storage without downtime.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
The trap here is that candidates often confuse the Hyperscale tier's storage limit with the Business Critical tier's in-memory OLTP or zone-redundancy features, leading them to select options that are technically correct for other tiers but not for Hyperscale.
Detailed technical explanation
Under the hood, Hyperscale decouples compute from storage using a tiered architecture: a compute node (SQL Server engine) with a local buffer pool cache, page servers that store data pages in Azure Blob Storage, and a log service that persists transaction logs. This design allows fast provisioning of additional read replicas (Option C) because new compute nodes can be attached to the same shared storage and log service without copying data, enabling horizontal read scaling for read-heavy workloads. A real-world scenario is a large e-commerce platform with terabytes of historical order data that needs to scale storage to 100 TB while maintaining low-latency reads for reporting queries.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
