Oracle Cloud Infrastructure 2020 HPC and Big Data Solutions Associate

A customer wants to store small files (KBs) workload in a filesystem.

What two options should you use to measure performance for this filesystem?

Compute nodes are on subnet2(l72.16.1.0/24) and there is a BM.Dense.I02.8 on subnet1.

(1 /2.16.0.0/24) that will serve as a bastion, file server and license server. The bastion will be accessed through a public IP with SSH.

Which security lists should you choose for an HPC cluster? If multiple options are possible, choose the one limiting access the most.

What HDFS replication factor should be used for locally attached storage In HDFS?

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?

Which two Oracle Cloud Infrastructure (OCI) storage options are supported for direct HDFS use in Hadoop?

A customer ran a Job on 2 BM.HPC2.36, and the job took 4 hours using 32 cores of each node. They later ran on 4 nodes and the Job took 3 hours.

What Is the efficiency gained?

Which three Hadoop distributions are supported on Oracle Cloud Infrastructure (OCI)?

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 connect remotely?

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?

You are comparing different processors for Monte-Carlo simula-tion with millions of single core executions.

What frequency will have the highest impact on the "time to solution" ?
