Question 1

What are two different types of Storage offerings available to build a filesystem on Oracle Cloud infrastructure (OCI)?

A.File Storage

B.Local NVMe SSDs on DenselO and HPC compute shapes

C.Object Storage

D.Block Volume Service

Question 2

What does the Terasort phase of the Terasort benchmark do?

A.It maps and reduces one terabyte of data into a smaller data set.

B.It maps and reduces source data in a parallel manner, leveraging data locality to minimize network transfer.

C.It randomly maps source data and reduces output to a smaller data set,

D.It randomly maps source data and increases output to a bigger data set.

Question 3

On Oracle Cloud Infrastructure (OCI), a customer wants to build a 3TB filesystem for high IOPS workloads (like relational databases, small files, etc).
Which action provides the highest IOPS using OCI block volumes for storage?

A.Attach three Block volumes of 1TB each and use filesystem Block size of 2M or higher.

B.Attach one Block volume of 3TB volume size and use filesystem Block size of 2M or higher.

C.Attach three Block volumes of 1TB each and use filesystem Block size of 4K.

D.Attach one Block volume of 3TB volume size and use filesystem Block size of 4K.

Question 4

Which two options are valid when configuring health check policies in Oracle Cloud Infrastructure (OCI) Load Balancing?

A.HTTP level health checks

B.UDP level health checks

C.FTP level health checks

D.TCP level health checks

Question 5

You have an HPC cluster running tightly coupled MPI jobs without VPN or Fast Connect.
The compute nodes are on subnet2(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?

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

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

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

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