Oracle Cloud infrastructure (OCI) Block Volume Storage supports sharing a Block Volume among multiple compute Instances in read/write or read only shareable mode.

Which two file systems should be used to allow multiple compute Instances to read/write data concurrently without any data loss?

A. Distributed File Systems like Gluster, OCFS2, GFS2

B. Linux File Systems like XFS, EXT4, EXT3, etc.

C. Network File System (NFS)

D. Parallel File Systems like Lustre, IBM Spectrum Scale(GPFS), BeeGFS, etc.

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.

Which Message Passing Interface (MPI) distribution is NOT available today?

A. OCI MPI

B. Intel MPI

C. Platform MPI

D. Open MPI
