You are deploying a new Azure Virtual Machine (VM) that will host a critical database. The database requires extremely low-latency disk performance and needs to support the highest possible IOPS. Which Azure VM disk type should you select to meet these requirements?
- AStandard HDD
- BPremium SSD
- CUltra Disk
- DStandard SSD
Show answer & explanationAnswer & explanation
Correct answer: C. Ultra Disk
Azure Ultra Disks offer the highest performance with extremely low latency and high IOPS, making them ideal for I/O-intensive workloads like critical databases.
Why the other options are wrong
- A. Standard HDD offers the lowest cost and performance, unsuitable for critical databases.
- B. Premium SSD offers high performance, suitable for many production databases, but Ultra Disks surpass them in extreme performance scenarios.
- D. Standard SSD provides good performance for general workloads but not the 'highest possible IOPS' or 'extremely low-latency' required.
Azure Ultra Disk
A high-performance, low-latency disk storage option for Azure VMs, offering configurable IOPS and throughput.
- Offers sub-millisecond latency.
- Provides highest IOPS and throughput among Azure disk types.
- Ideal for I/O-intensive applications like databases.
Memory trick: For ultimate speed, go Ultra; everything else is just a warm-up.
