On Oracle Cloud Infrastructure (OCI), a customer wants to build a 3TB filesystem for high IOPS workloads (like relational databases, small files, etc).Which action provides the highest IOPS using OCI block volumes for storage?

• Attach one Block volume of 3TB volume size and use filesystem Block size of 4K.
• Attach one Block volume of 3TB volume size and use filesystem Block size of 2M or higher.
• Attach three Block volumes of 1TB each and use filesystem Block size of 2M or higher.
• Attach three Block volumes of 1TB each and use filesystem Block size of 4K.

Which statement explains how instances are distributed in an instance pool?

• The instances In a pool are distributed between availability domains only.
• The instances in a pool are distributed evenly between two fault domains.
• The instances in a pool are not distributed across fault domains.
• The instances in a pool are distributed across all fault domains In a best-effort manner based on capacity.
• It is not possible to distribute instances across availability domains or fault domains.

A two node clustered/parallel filesystem built using Baremetal Compute shape (BM.Standard2.52) and Block Volume Storage delivers maximum sustained aggregate IO throughput of 5GB/s for read and write, while storing a single copy of the data (replica=l) in filesystem.What will be the maximum sustained aggregate IO throughput for read and write, when two copies of the data (replica=2) are stored in filesystem for High Availability?

• 5GB/s for both (read and write)
• 2.5GB/s for read and 5GB/s for write
• 2.5GB/S for write and 5GB/s for read
• 2.5GB/s for both (read and write)

A customer has a Spark workload they are considering moving to Oracle Cloud Infrastructure (OCI). What option should they consider?

• Oracle Data Flow
• Self-managed Hadoop deployment
• Self-managed Spark deployment
• Big Data Service

Which is NOT an advantage associated with moving a Big Data workload to Oracle Cloud Infrastructure (OCI)?

• managed service offerings to support common Big Data workloads
• best price / performance for Big Data workloads In the Cloud
• availability of Oracle Airflow
• Object Storage as Data Lake
• dynamically scale capacity against workload
