AI-200 Containerized AI Workloads Practice Question
You are deploying a distributed PyTorch training job across multiple nodes in an Azure Kubernetes Service (AKS) cluster. Which mechanism should you use to facilitate high-speed, low-latency inter-node communication required for gradient synchronization?
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
✓
Node placement with GPU-optimized VM series (such as NDm A100 v4) and InfiniBand support
Distributed deep learning frameworks require low-latency networks; InfiniBand or high-performance SR-IOV enabled GPU VMs (like ND-series) with MPI are standard. In AKS, Azure CNI with appropriate networking and node selection enables high-performance setups.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Kubenet basic networking with dynamic NAT
Why it's wrong here
Kubenet uses basic routing tables which lacks the performance required for massive distributed AI training workloads.
- ✓
Node placement with GPU-optimized VM series (such as NDm A100 v4) and InfiniBand support
Why this is correct
Using specialized GPU VMs equipped with SR-IOV and InfiniBand provides the high throughput needed for distributed gradient sync.
- ✗
Azure Application Gateway Ingress Controller (AGIC)
Why it's wrong here
AGIC is an ingress controller for HTTP/HTTPS traffic routing, not inter-pod distributed training communication.
- ✗
Standard Azure CNI with Network Policies enabled
Why it's wrong here
Network policies enforce security rules but do not optimize distributed training network performance.
