  Correct Answer: C

• Question 43:

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

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

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

  Correct Answer: B

• Question 44:

  A two node clustered/parallel filesystem built using Baremetal Compute shape (BM.Standard2.52) and Block Volume Storage delivers maximum sustained aggregate IO throughput of 5GB/s for read and write, while storing a single copy of the data (replica=l) in filesystem.

  What will be the maximum sustained aggregate IO throughput for read and write, when two copies of the data (replica=2) are stored in filesystem for High Availability?

  A. 5GB/s for both (read and write)

  B. 2.5GB/s for read and 5GB/s for write

  C. 2.5GB/S for write and 5GB/s for read

  D. 2.5GB/s for both (read and write)

  Correct Answer: D

• Question 45:

  Oracle Cloud infrastructure (OCI) Block Volume Storage supports sharing 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?

  A. Distributed File Systems like Gluster, OCFS2, GFS2

  B. Linux File Systems like XFS, EXT4, EXT3, etc.

  C. Network File System (NFS)

  D. Parallel File Systems like Lustre, IBM Spectrum Scale(GPFS), BeeGFS, etc.

  Correct Answer: A

• Question 46:

  You are building a RDMA cluster on a private network with 10000 cores. What CIDR will work in the VCN: 172.16.0.0/16?

  A. 172.16.32.0/23

  B. 10.0.1.0/23

  C. 172.16.32,0/16

  D. 10.0.1.0/24

  Correct Answer: A

• Question 47:

  What are the three components for configuring autoscallng on Oracle Cloud Infrastructure (OCI)?

  A. Monitoring Is enabled on the instances in the instance pool.

  B. The instance pool supports the maximum number of instances that you want to scale to.

  C. You have an instance pool.

  D. You have a load balancer.

  E. You have Bare Metal instances.

  Correct Answer: ADE

• Question 48:

  Which two Oracle Cloud Infrastructure (OCI) shapes are a good choice for Spark based workloads?

  A. HPC

  B. VM Standard

  C. BM Standard

  D. GPU

  Correct Answer: AC

• Question 49:

  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.

  A. Subnet1: 0.0.0.0 for all TCP/UDP ports, subnet2: 172.16.0.0/16 for all TCP/UDP ports

  B. Subnet1: 0-0.0.0 for TCP port 22, subnet 1 and 2: 172.16.0.0/23 for all TCP/UDP ports

  C. Subnet1: 172.16-1.0/24 for port 22, subnet2: 172.16.1.0/24 for all TCP/UDP ports

  D. Subnet1: 0-0.0.0 for TCP port 22, subnet 2: 172.16.0.0/16 for TCP port 22
