Quick Answer
The answer is Azure Ultra Disk Storage. This is the correct choice because it is the only Azure managed disk that is SAP HANA certified for production databases requiring high IOPS and sub-millisecond latency, with the ability to provision up to 300,000 IOPS and 2,000 MB/s throughput per disk, easily covering the 4 TB capacity requirement. On the AZ-305 exam, this question tests your understanding of SAP HANA certified storage configurations, often appearing as a trap where Premium SSD v2 is a distractor—while it offers high performance, it lacks SAP HANA certification for production workloads, and Azure NetApp Files, though performant, is not a managed disk and requires NFS configurations that may not meet strict block storage certification. Remember the memory tip: "Ultra is the only one certified for HANA production"—if the scenario mentions SAP HANA certification and high IOPS, always choose Ultra Disk.
This AZ-305 practice question tests your understanding of design data storage solutions. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 financial services company is migrating its on-premises SAP HANA database to Azure. The database requires high IOPS and low latency with a capacity of 4 TB. They need to choose a storage solution that supports SAP HANA certified configurations. Which Azure storage solution should they use?
Azure Premium SSD v2
Why wrong: Premium SSD v2 may not meet all SAP HANA certification requirements.
Azure Ultra Disk Storage
Azure Ultra Disk Storage provides high IOPS, low latency, and is certified for SAP HANA.
Azure Standard HDD
Why wrong: Standard HDD is too slow for SAP HANA requirements.
Azure NetApp Files
Why wrong: Azure NetApp Files is not certified for SAP HANA.

Correct answer & explanation
Azure Ultra Disk Storage
Azure Ultra Disk Storage is the correct choice because it is the only Azure managed disk that is SAP HANA certified for high IOPS and sub-millisecond latency, which is critical for SAP HANA workloads. It supports up to 300,000 IOPS and 2,000 MB/s throughput per disk, and can be provisioned with up to 64 TB capacity, easily covering the 4 TB requirement. Premium SSD v2 is not SAP HANA certified for production databases, and Azure NetApp Files, while offering high performance, is not a managed disk and requires specific NFS configurations that may not meet SAP HANA's strict certification requirements for block storage.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Azure Premium SSD v2
Why it's wrong here
Premium SSD v2 may not meet all SAP HANA certification requirements.
Azure Ultra Disk Storage
Why this is correct
Azure Ultra Disk Storage provides high IOPS, low latency, and is certified for SAP HANA.

Azure Standard HDD
Why it's wrong here
Standard HDD is too slow for SAP HANA requirements.
Azure NetApp Files
Why it's wrong here
Azure NetApp Files is not certified for SAP HANA.
Common exam traps
The trap here is that candidates often assume Premium SSD v2 is the best choice for all high-performance workloads, but SAP HANA has specific certification requirements that exclude Premium SSD v2 for production databases, making Ultra Disk the only correct option among the managed disks listed.
Detailed technical explanation
Ultra Disk Storage uses a distributed storage architecture that allows independent provisioning of IOPS and throughput, enabling fine-grained performance tuning for latency-sensitive workloads like SAP HANA. Under the hood, it leverages NVMe over Fabrics and a dedicated network path to minimize jitter, which is critical for SAP HANA's log writes and data persistence. In real-world scenarios, a financial services company running SAP HANA on Ultra Disk can achieve consistent sub-millisecond latency even under peak transaction loads, avoiding the performance degradation seen with shared storage solutions.
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.
