On Oracle Cloud Infrastructure (OCI), a customer wants to build a3TB 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 one Block volume of 3TB volume size and use filesystem Block size of 2M or higher.
• B.Attach three Block volumes of 1TB each and use filesystem Block size of 4K.
• C.Attach three Block volumes of 1TB each and use filesystem Block size of 2M or higher.
• D.Attach one Block volume of 3TB volume size and use filesystem Block size of 4K.

Which two performance metrics can be used to trigger scaling actions In Autoscaling?

• A.Network throughput
• B.Memory utilization
• C.Network latency
• D.Disk IOPS
• E.CPU utilization

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?

• A.1: BM.Standard.E3.128 2: BM.HPC2.36
• B.1: BM.Standard-2.52 2: BM.HPC2-36
• C.1: BM.HPC2.36 2: BM.Standard.E3-128
• D.1: BM.HPC2.36 2: BM.Standard.2.52

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?

• A.1TB
• B.800GB
• C.32TB
• D.500GB

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?

• A.Subnet1: 172.16.1.0/24 for port 22, subnet2: 172.16.1.0/24 for all protocols
• B.Subnet1: 0.0.0.0 forTCP port 22, subnet 1 and 2: 172.16.0.0/23 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
