• A.  Oracle Data Flow
• B.  Self-managed Hadoop deployment
• C.  Big Data Service
• D.  Self-managed Spark deployment

You have two different workloads, workload 1 does not scale very well (~100 cores) and requires a very high memory bandwidth, and a workload 2 that Is compute bound and IO intensive.
Which Instances shouldyou select?

• A.  1: BM.Standard.E3.128 2: BM.HPC2.36
• B.  1: BM.Standard-2.52 2: BM.HPC2-36
• C.  1: BM.HPC2.36 2: BM.Standard.2.52

• C.  Instances and boot volumes will be deleted.
• D.  Only the Instances will be deleted.
• E.  Nothing will be deleted.

On Oracle Cloud Infrastructure (OCI), a customer wants to build a3TB filesystem for high IOPS workloads (like relational databases, small files, etc).
Which action provides the highest IOPS using OCI block volumes for storage?

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

Oracle Cloud infrastructure (OCI) Block Volume Storage supportssharing 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 Systemslike 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.
