IOPS per disk: 2000
throughput per disk 100 MB per second
number of highly utilized disks: 40
You need to scale the service.
What should you recommend?

Answer is Correct!
Premium storage disks:
Premium Storage supports VM disks that can be attached to specific size-series VMs. Premium Storage supports DS-series, DSv2-series, GS-series, Ls-series, and Fs-series VMs. You have a choice of seven disk sizes: P4 (32GB), P6 (64GB), P10 (128GB), P20 (512GB), P30 (1024GB), P40 (2048GB), P50 (4095GB).

I wonder why they ask this type of question considering that the tiers change all the time.
