質問 1

A file system is built using BM.Standard2.52 Compute shape for File Servers. One 25 Gbps NIC/network card is used to connect to 10 Block Volumes of 1TB each (max. 4#0MB/s per volume). The other 25 Gbps NIC is used for sending/receiving data to/from client nodes.
File system client instances which mount the file system are provisioned using VM.Standard2.16 Compute shapes. (Network bandwidth: l6.4Gbps(2050 MB/s)) What is the max IO theoretical throughput a client node can get?

（A）3125 MB/s

（B）2050 MB/s

（C）6250 MB/s

（D）4800 MB/s

（A）Distributed File Systems like Gluster, OCFS2, GFS2

（B）Network File System (NFS)

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

（D）Linux File Systems like XFS, EXT4, EXT3, etc.

質問 5

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 TCP port 22, subnet 1 and 2: 172.16.0.0/23 for all TCP/UDP ports

（B）Subnet1: 172.16-1.0/24 for port 22, subnet2: 172.16.1.0/24 for all TCP/UDP ports

（C）Subnet1: 0-0.0.0 for TCP port 22, subnet 2: 172.16.0.0/16 for TCP port 22

（D）Subnet1: 0.0.0.0 for all TCP/UDP ports, subnet2: 172.16.0.0/16 for all TCP/UDP ports

質問 6

On a RDMA cluster, a latency test was conducted, with these results:

What should you do?

（A）Latency Is not critical, check the bandwidth.

（B）Rerun the test and see If It Is consistent.

（C）Report the higher latency through a SR.

（D）Nothing, this behavior is normal.
