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?  Put the data in object storage, and mount It using s3fs-fuse project.  Build a file-system using NVMe on Dense shapes.

NEW QUESTION 22On Oracle Cloud Infrastructure (OCI), a customer wants to build a 3TB fllesystem for high throughput-oriented workloads.Which action provides the highestIO throughput using OCI block volumes for storage?  Attach one Block volume of 3TB volume size and use fllesystem Block size of 256K or lower.  Attach one Block volume of 3TB volume size and use fllesystem Block size of 1M or higher.  Attach threeBlock volumes of 1TB each and use fllesystem Block size of 256K or lower.  Attach three Block volumes of 1TB each and use filesystem Block size of 1M or higher. NEW QUESTION 23You 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. NEW QUESTION 24Which workload is massively parallel In nature?  Map/Reduce  Streaming  SQL Queries  ETL NEW QUESTION 25You are running a cluster using multiple BM.Standard2.52 machines. Themodel is on a NFS share running on block volume- You’ve tried doubling the number of machines but It’s not running any faster.Which two actions could potentially speed up this tightly coupled workload?  Switch to FSS for your file system.  Use ClusterNetworking.  Use BM.HPC2.36.  Switch to ESS mode. NEW QUESTION 26What HDFS replication factor should be used for locally attached storage In HDFS?  4  2  3  1 NEW QUESTION 27You’ve spun up a GPU instance with the standard OEL linage (GPU version) from theconsole network on Oracle Cloud Infrastructure (OCI).What action do you need to do In order to be able to visualize your desktop remotely?  Install Open MPl for distributed GPU access.  Install a desktop and a VNC server.  Install NVIDIA drivers.  Open a remote serial console. NEW QUESTION 28You are building a large filesystem to maximize throughput of large files using high performance block volume and BM.Standard2.52 as file servers.Which block volumes configuration should you choose to ensure aggregate Block volume throughput is higher than network bandwidth of file servers?  7 Block Volumes of 800 GB  32 Block Volumes of 800 GB  5 Block Volumes of 32 TD  6 Block Volumes of 32 TB NEW QUESTION 29A customer wants to store small files(KBs) workload in a filesystem.What two options should you use to measure performance for this filesystem?  Amount of Memory on file servers  CPU processor clock speed for faster processing  High IOPS  Low Latency NEW QUESTION 30Whichis an accurate analogy for Amdahl’s law?  There Is no such thing as a free lunch.  An orchestra can only play well together If they have a great conductor.  When chopping vegetable to prepare a 4 person-meal, 2 persons are going twice as fast as one, but 8 people may not be 8 times faster.  In track and field, the 4xl00m relay is only 17% faster than the world record for individual 400m. NEW QUESTION 31Which two options are valid when configuring health check policies in Oracle Cloud Infrastructure (OCI) Load Balancing?  FTP level health checks  TCP level health checks  UDP level health checks  HTTP level health checks NEW QUESTION 32On a RDMA cluster, a latency test was conducted, with these results:What should you do?  Nothing, this behavior is normal.  Latency Is not critical, check the bandwidth.  Rerun the test and see If It Is consistent.  Report the higher latency through a SR. NEW QUESTION 33Oracle 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?  Distributed File Systemslike 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. NEW QUESTION 34Which is NOT an advantage associated with moving a Big Data workload to Oracle Cloud Infrastructure (OCI)?  managed service offerings tosupport common Big Data workloads  best price / performance for Big Data workloads In the Cloud  availability of Oracle Airflow  Object Storage as Data Lake  dynamically scale capacity against workload NEW QUESTION 35What are the three components for configuring autoscallng on Oracle Cloud Infrastructure (OCI)?  Monitoring Is enabled on the instances in the instance pool.  The instance pool supports the maximum number of instances that you want to scale to.  You have an instance pool.  You have a load balancer.  You have Bare Metal instances. NEW QUESTION 36Which statement correctly describes Oracle Data Science?  It is primarily focused on supporting a single data scientist.  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. NEW QUESTION 37Which two performance metrics can be used to trigger scaling actions In Autoscaling?  Network latency  Memory utilization  Network throughput  Disk IOPS  CPU utilization NEW QUESTION 38You 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?  One Block Volume of 10TB size  10 Block Volumes of 1TB size  8 Block Volumes of 1.25TB size  20 Block Volumes of 500GB size NEW QUESTION 39Which statement explains how instances are distributed in an instance pool?  The instances In a pool are distributed between availability domains only.  The instances in a pool are distributed evenly between two fault domains.  The instances in a pool are not distributed across fault domains.  The instances in a pool are distributed across all fault domains In a best-effortmanner based on capacity.  It is not possible to distribute instances across availability domains or fault domains. NEW QUESTION 40A 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?  2050 MB/s  4800 MB/s  3125 MB/s  6250 MB/s NEW QUESTION 41A Linux visualization instance Is in a public subnet with security list 0.0-0.0/0 for TCP port 22.
