Question 399:
Your company has developed a complex numerical calculation system used by some scientific and medical organizations in your country. The whole application is using the Hadoop engine with an HBase database. Because of the complex nature of the business, the overall setup runs in a private data center spread into two facilities for redundancy. The application needs high I/O bandwidth for the workload. Although they are not running the workloads with full capacity at the moment, there are some new developments in the business, and they are extending their services to a few other organizations in a different country. Due to compliance reasons, they plan to host their application in the cloud instead of setting up data center facilities in the new country. They want the same setup to be migrated over the cloud and still achieve the low latency, high I/O, and redundant cluster setup. Please select a valid option that can help replicate the setup on AWS.
Answer options:
A.Use the I3 instances with Enhanced Networking enabled and RAID 0 configuration to achieve the disk mirroring. B.Use the I3 instances with Enhanced Networking enabled and RAID 1 configuration to achieve the disk mirroring. C.Use the I3 instances with Enhanced Networking enabled and use the Placement Group with Partitioned option to spread the clusters across multiple availability zones. D.Use the I3 instances with Enhanced Networking enabled and use the Cluster Placement Group with an option to spread the clusters across multiple availability zones.
