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)

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
