Your Azure subscription contains several storage accounts shown in a table. You will enable Azure Site Recovery replication for Server1. The replication must support backing up high-churn workloads and keep costs low. Which storage account should you designate as the Cache storage?

Correct answer: storage1.
Why this is the answer
storage1 is a Premium SSD storage account, which is ideal for Azure Site Recovery cache storage, especially for high-churn workloads. Premium SSDs offer high IOPS and low latency, ensuring efficient replication and minimizing the impact on source server performance. storage2 is a Standard HDD storage account. While cost-effective, it has lower IOPS and higher latency, making it unsuitable for high-churn workloads and potentially impacting replication performance. storage3 is a Standard SSD storage account. It offers better performance than Standard HDD but is still generally not recommended for high-churn ASR cache due to potential performance bottlenecks compared to Premium SSD. storage4 is a Blob storage account. Blob storage is not supported for use as a cache storage account for Azure Site Recovery.
