A customer has a very busy workload. The model is very large (1 PB range) and only some small files are updated for new jobs. Throughput needed during the run is roughly 25GB/s.
What Is a fast and cost-conscious way to handle the file system?
A. Put the data in object storage, and mount It using s3fs-fuse project.
B. Build a file-system using NVMe on Dense shapes. Then move the data to object storage when not needed.
C. Build a file system using Block volumes and Standard BMs, take advantage of the different block volume performances levels.
D. Use NVMe on HPC shapes to build a File System with the RDMA connection.
You are building a file system that needs to handle large files with a lot of nodes reading at the same time. What minimum size of block volume maximizes throughput for large files?
A. 800GB
B. 1TB
C. 32TB
D. 500GB

D. Terasort
A file system is built using BM.Standard2.52 Compute shape for File Servers. One 25 Gbps NIC/network card is used to connect to 10 Block Volumes of 1TB each (max. 4#0MB/s per volume). The other 25 Gbps NIC is used for sending/receiving data to/from client nodes.
File system client instances which mount the file system are provisioned using VM.Standard2.16 Compute shapes. (Network bandwidth: l6.4Gbps(2050 MB/s))
What is the max IO theoretical throughput a client node can get?
A. 2050 MB/s
B. 4800 MB/s
C. 3125 MB/s
D. 6250 MB/s
A customer has a Spark workload they are considering moving to Oracle Cloud Infrastructure (OCI). What option should they consider?
A. Oracle Data Flow
B. Self-managed Hadoop deployment
C. Self-managed Spark deployment
D. Big Data Service
Which Is a common business problem for customers running Big Data workloads?
A. Costs associated to process a large scale data set
B. Cost associated with Disaster Recovery for large deployments
C. Ability to process a small data set at the minimum cost as possible
D. Ability to process a large data set at the maximum cost as possible
You are building a file system of 10TB Storage Capacity with only one file server using "Balanced Elastic Performance tier" Oracle Cloud Infrastructure (OCI) Block Volume Storage. Balanced Elastic Performance tier throughtput scales at 480 KBPS/GB up to a maximum of 480 MBPS per volume.
Which two options are correct about how many Block Volumes you can attach to the file server to get maximum IO throughput?
A. One Block Volume of 10TB size
B. 10 Block Volumes of 1TB size
C. 8 Block Volumes of 1.25TB size
D. 20 Block Volumes of 500GB size

A. Distcp
B. Data Transfer Appliance
C. Fast Connect
D. Object Storage
E. GoldenGate
