NO.27 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?

Distcp

Data Transfer Appliance

Fast Connect

Object Storage

GoldenGate

NO.28 A Linux visualization instance Is in a public subnet with security list 0.0-0.0/0 for TCP port 22. What other rule do you absolutely need to be able to connectremotely?

Open all protocols for your specific IP address.

Create a Stateless Egress rule for port 22-

Open TCP ports 5900 to 5910 for 0.0.0.0/0.

No other additional rules are needed. It is possible to connect as is.

NO.29 Which two Oracle Cloud Infrastructure (OCI) shapes are a good choice for Spark based workloads?

HPC

VM Standard

BM Standard

GPU

NO.30 When running a high memory workload, what should be your machine of choice?

BM.Standard.E2.64

BM.Standard.E3.128

BM.HPC2.36

BM.GPU3.8

NO.31 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?

1: BM.HPC2.36 2: BM.Standard.2.52

1: BM.Standard.E3.128 2: BM.HPC2.36

1: BM.HPC2.36 2: BM.Standard.E3-128

1: BM.Standard-2.52 2: BM.HPC2-36

NO.32 When an instance pool scales in, what is the correct order that the instances are terminated?

The number of instances is balanced across availability domains, the oldest instance within the fault domain is terminated, the number of instances Is balanced across fault domains.

The number of instances is balanced across availability domains, the number of instances is balanced across fault domains, the oldest instance within the fault domain is terminated.

The oldest instance within the fault domain is terminated, the number of instances is balanced across availability domains, the number of instances is balanced across fault domains.

The number of instances is balanced across fault domains, the number of instances is balanced acrossfault domains, the oldest instance within the fault domain is terminated.

NO.33 Which 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.

NO.34 Which 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

NO.35 You have an HPC cluster running tightly coupled MPI jobs without VPN or Fast Connect.
The compute nodes are onsubnet2(172.16.1.0/24), and there is a BM.Dense.I02.8 on subnet1 (172-16.0.0/24) that will serve as a bastion and file server.
What security lists should you choose to be able to run the workloads while limiting access as possible?

Subnet1: 0.0.0.0 forTCP port 22, subnet 1 and 2: 172.16.0.0/23 for all protocols

Subnet1: 0.0.0.0 for all protocols, subnet2: 172.16.0-0/16 for all protocols

Subnet1: 172.16.1.0/24 for port 22, subnet2: 172.16.1.0/24 for all protocols

Subnet1: 0.0.0.0 for TCP port 27, subnet 7: 172.16.0.0/16 for TCP port 22

NO.36 You are building a RDMA cluster on a private network with 10000 cores. What CIDR will work in theVCN:
172.16.0.0/16?

172.16.32.0/23

10.0.1.0/23

172.16.32,0/16

10.0.1.0/24

800GB

1TB

32TB

500GB

NO.39 You 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.
