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.10.0.1.0/23
• B.172.16.32.0/23
• C.172.16.32,0/16
• D.10.0.1.0/24

You are building a large filesystem to maximize throughput of large files using high performance block volume and BM.Standard2.52 as file servers.
Which block volumes configuration should you choose to ensure aggregate Block volume throughput is higher than network bandwidth of file servers?

• A.7 Block Volumes of 800 GB
• B.6 Block Volumes of 32 TB
• C.32 Block Volumes of 800 GB
• D.5 Block Volumes of 32 TD

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.32TB
• B.1TB
• C.500GB
• D.800GB

A customer has a very busy workload. The model is very large (1 PB range) and only some small files are updated for new jobs. Throughput needed during the run is roughly 25GB/s.
What Is a fast and cost-conscious way to handle the file system?

• A.Use NVMe on HPC shapes to build a File System with the RDMA connection.
• B.Put the data in object storage, and mount It using s3fs-fuse project.
• C.Build a file system using Block volumes and Standard BMs, take advantage of the different block volume performances levels.
• D.Build a file-system using NVMe on Dense shapes. Then move the data to object storage when not needed.

A file system is built using two BM.Standard2.52 Compute shapes for File servers. On each file server, one 25 Gbps (3125 MB/s) NIC/network card is used to connect to 10 Block Volumes of 1TB each (max. 480MB/s per volume) and 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 aggregate IO throughput (theoretical) of the file system?

• A.9600 MB/s
• B.3125 MB/s
• C.4800 MB/s
• D.6250 MB/s
