Topic 1 Question 63
Your organization has an existing app that just went viral. The app uses a Cloud SQL for MySQL backend database that is experiencing slow disk performance while using hard disk drives (HDDs). You need to improve performance and reduce disk I/O wait times. What should you do?
Export the data from the existing instance, and import the data into a new instance with solid-state drives (SSDs).
Edit the instance to change the storage type from HDD to SSD.
Create a high availability (HA) failover instance with SSDs, and perform a failover to the new instance.
Create a read replica of the instance with SSDs, and perform a failover to the new instance

- 正解だと思う選択肢: A
You can't edit disk time, this setting is permanent. https://stackoverflow.com/questions/72034607/can-i-change-storage-type-from-hdd-to-ssd-on-cloud-sql-after-creating-an-instanc You also can't choose disk type for read replica.

👍 3pk3492022/12/24A. B would not work. You cannot change the disk type of the instance after it’s created. C is wrong for the same reason. Adding HA would create a failover replica with the same disk type as the primary. The same is true for a read replica, so D is wrong as well. Leaves A.
