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?
Correct Answer: B Vote an answer
On Oracle Cloud Infrastructure (OCI), a customer wants to build a3TB filesystem for high IOPS workloads (like relational databases, small files, etc).
Which action provides the highest IOPS using OCI block volumes for storage?
Correct Answer: D Vote an answer
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?
Correct Answer: D Vote an answer
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.

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?
