Correct Answer: BCFor a real-time analytics application requiring over 768GB of database capacity and the fastest possible data access, it is crucial to upgrade to servers that offer better performance than the current HPE ProLiant DL380 Gen9 servers. HPE ProLiant DL380 Gen10 servers provide significant improvements in processing power, memory capacity, and overall performance compared to Gen9 servers. Additionally, incorporating HPE Scalable Persistent Memory offers ultrafast data access, which is essential for real-time analytics workloads. Together, these solutions will address both the capacity and speed requirements of the application.
