• B.An orchestra can only play well together If they have a great conductor.
• C.There Is no such thing as a free lunch.
• D.In track and field, the 4xl00m relay is only 17% faster than the world record for individual 400m.

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.Parallel File Systems like Lustre, IBM Spectrum Scale(GPFS), BeeGFS, etc.
• B.Network File System (NFS)
• C.Distributed File Systems like Gluster, OCFS2, GFS2
• D.Linux File Systems like XFS, EXT4, EXT3, etc.

• A.1TB
• B.10TB
• C.32TB
• D.100GB

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?

• A.2.5GB/s for read and 5GB/s for write
• B.2.5GB/S for write and 5GB/s for read
• C.2.5GB/s for both (read and write)
• D.5GB/s for both (read and write)

On a RDMA cluster, a latency test was conducted, with these results:

What should you do?

• A.Nothing, this behavior is normal.
• B.Latency Is not critical, check the bandwidth.
• C.Rerun the test and see If It Is consistent.
• D.Report the higher latency through a SR.
