A cloud architect is designing a distributed block storage solution that will support application HA. The solution will consist of 10 nodes with all SAS devices. There are five racks available in the data center. Each rack has a single top-of-rack access layer switch with sufficient bandwidth to the aggregate layer. Each node will have multiple connections to the local top-of-rack switch.

B. One pool with 50% SSD and 50% SAS nodes distributed equally across five racks

C. One pool with SSD nodes distributed equally across five racksOne pool with all SAS nodes distributed equally across five racks

D. One pool with 50% SSD and 50% SAS nodes located in one rackOne pool with 50% SSD and 50% SAS nodes located in a different rack

An organization is developing a cloud-native social-media website. The website will be written using elastic principles. When the website scales, it can add additional web, application and database instances to meet dynamic workload demand.
