For customers who want to copy HDFS data from their on-premise Hadoop cluster to Oracle Cloud Infrastructure (OCI),which three are Oracle supported methods?

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

You are building a filesystem 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 pervolume.
Which two options are correct about how many Block Volumes you can attach to the file server to get maximum IO throughput?

• A.20 Block Volumes of 500GB size
• B.10 Block Volumes of 1TB size
• C.One Block Volume of 10TB size
• D.8 Block Volumes of 1.25TB size

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

You are building a file system that needs to handle large files with a lot of nodes reading at the same time.
What should be your main goal?

• A.Maximize Latency while keeping throughput above a certain threshold.
• B.Maximize throughput.
• C.Minimize latency.
• D.Minimize throughput while keeping the latency low.

Which workload is massively parallel In nature?

• A.Map/Reduce
• B.ETL
• C.SQL Queries
• D.Streaming
