NO.16 When running a high memory workload, what should be your machine of choice?

NO.17 You are building a filesystem to maximize throughput of large files using high performance block volume and BM.Standard2.52 as file server.
Which block volume configuration should you choose to ensure aggregate Block volume throughput is higher than network bandwidth of a file server?

NO.18 You are building a file system that needs to handle large files with a lot of nodes reading at the same time.
What minimum size of block volume maximizes throughput for large files?

NO.19 Which Is a common business problem for customers running Big Data workloads?

NO.20 A file system is built using BM.Standard2.52 Compute shape for File Servers. One 25 Gbps NIC/network card is used to connect to 10 Block Volumes of 1TB each (max. 4#0MB/s per volume). The other 25 Gbps NIC is used for sending/receiving data to/from client nodes.
File system client instances which mount the file system are provisioned using VM.Standard2.16 Compute shapes. (Network bandwidth: l6.4Gbps(2050 MB/s)) What is the max IO theoretical throughput a client node can get?

NO.21 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?

NO.22 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?

NO.23 What HDFS replication factor can be used with Block Volumes to optimize cost?

NO.24 A customer has a Spark workload they areconsidering moving to Oracle Cloud Infrastructure (OCI). What option should they consider?

NO.25 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?

NO.26 A customer has decided to use Oracle Cloud Infrastructure (OCI) for theirDisaster Recovery (DR) site for an on-premises Hadoop cluster. They have an RPO of 4 hours, and an RTO of 1 hour.
Which two options should they consider on OCI to meet their DR requirements?

NO.27 Which two performance metrics can be used to trigger scaling actions In Autoscaling?

NO.28 You are architecting the infrastructure for a file system.
What are the different criteria you should use, and in what order to build a filesystem for optimal performance?

NO.29 Which workload is massively parallel In nature?

NO.30 Which two Oracle Cloud Infrastructure (OCI) shapes are a good choice for Spark based workloads?
