1Z0-1072-26 Compute Practice Question
You are planning to deploy a high-performance computing (HPC) cluster on OCI requiring extremely high packet per second (PPS) and ultra-low latency between compute nodes. Which feature must you utilize?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Cluster Networks with RDMA (Remote Direct Memory Access)
OCI HPC and bare metal clusters support Cluster Networks with RDMA (Remote Direct Memory Access) over RoCE (RDMA over Converged Ethernet) for ultra-low latency and high throughput.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
NAT Gateway with bandwidth throttling disabled
Why it's wrong here
NAT gateways allow instances in private subnets to access the internet, not HPC clustering.
- ✓
Cluster Networks with RDMA (Remote Direct Memory Access)
Why this is correct
Cluster Networks provide RDMA networking for MPI-based HPC workloads requiring ultra-low latency.
- ✗
Public IP addresses on all compute nodes
Why it's wrong here
Public IPs expose nodes to the internet and do not provide low-latency HPC fabrics.
- ✗
OCI Local Peering Gateway
Why it's wrong here
Local peering gateways connect VCNs within the same region, not HPC node interconnects.
