• It enables data science teams to build, train, and manage machine learning models on Oracle Cloud.
  
• It provides management for on-premise machine learning models.
  
• Oracle's Data Science model catalog holds contains only the model artifact.
  

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?

• Maximize Latency while keeping throughput above a certain threshold.
  
• Maximize throughput.
  
• Minimize latency.
  
• Minimize throughput while keeping the latency low.
  

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?

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