Multiple Choice Questions
1. Which is NOT a suitable use case for EKS Hybrid Nodes?
A. Utilizing GPU servers in on-premises data centers B. Data locality requirements for regulatory compliance C. Running purely cloud-native workloads D. Latency-sensitive edge workloads
Show Answer
Answer: C. Running purely cloud-native workloads
Explanation: Purely cloud-native workloads are more efficiently run on regular EKS node groups or Fargate. Hybrid Nodes are used when there are special requirements (on-premises, edge, regulatory, etc.).
Suitable Use Cases for EKS Hybrid Nodes:
- Utilizing on-premises GPU/specialized hardware
- Data sovereignty/regulatory compliance requirements
- Latency-sensitive edge computing
- Cloud migration transition period
- Protecting existing infrastructure investments
2. Which operating system is supported by EKS Hybrid Nodes?
A. Windows Server 2019 only B. Ubuntu 20.04/22.04, Amazon Linux 2023, RHEL 8/9 C. macOS Ventura or later D. FreeBSD 13 or later
Show Answer
Answer: B. Ubuntu 20.04/22.04, Amazon Linux 2023, RHEL 8/9
Explanation: EKS Hybrid Nodes only supports Linux-based operating systems. Supported OS versions include:
- Ubuntu 20.04 LTS, 22.04 LTS
- Amazon Linux 2023
- Red Hat Enterprise Linux (RHEL) 8, 9
- Bottlerocket (container-optimized OS)
# Check OS version
cat /etc/os-release
# Check kernel version (5.4 or later recommended)
uname -r3. Which is NOT a minimum requirement for running GPU workloads on Hybrid Nodes?
A. NVIDIA Driver 525 or later B. CUDA Toolkit 11.8 or later C. Minimum 4GB GPU memory D. x86_64 or arm64 architecture is mandatory
Show Answer
Answer: D. x86_64 or arm64 architecture is mandatory
Explanation: x86_64 or arm64 architecture is a CPU architecture requirement, not a direct requirement for GPU workloads. Key GPU workload requirements are:
- NVIDIA Driver: 525 or later (CUDA 12 support)
- CUDA Toolkit: 11.8 or later
- GPU Memory: Minimum 4GB recommended (varies by workload)
- containerd: 1.6 or later (GPU container support)
# Check NVIDIA driver version
nvidia-smi --query-gpu=driver_version --format=csv,noheader
# Check CUDA version
nvcc --version4. What are the minimum hardware requirements for EKS Hybrid Nodes?
A. CPU 1 core, Memory 512MB B. CPU 2 cores, Memory 2GB C. CPU 4 cores, Memory 8GB D. CPU 8 cores, Memory 16GB
Show Answer
Answer: B. CPU 2 cores, Memory 2GB
Explanation: The minimum hardware requirements for EKS Hybrid Nodes are:
| Resource | Minimum | Recommended |
|---|---|---|
| CPU | 2 cores | 4 cores or more |
| Memory | 2GB | 4GB or more |
| Disk | 20GB | 50GB or more (SSD recommended) |
| Network | 100Mbps | 1Gbps or more |
Production environments may require higher specifications depending on workload requirements.
5. Which is NOT a required software component for EKS Hybrid Nodes configuration?
A. containerd runtime B. kubelet C. Docker Engine D. aws-iam-authenticator
Show Answer
Answer: C. Docker Engine
Explanation: EKS Hybrid Nodes uses containerd as the container runtime, and Docker Engine is not required. Required components are:
- containerd: Container runtime (1.6 or later)
- kubelet: Kubernetes node agent
- aws-iam-authenticator: AWS IAM authentication
- CNI plugins: Container networking
# nodeadm automatically installs components
sudo nodeadm init --config-source file://nodeadm-config.yaml
# Check installed components
systemctl status containerd
systemctl status kubelet6. What is the minimum NVIDIA driver version required for using H100 GPUs with Hybrid Nodes?
A. 450.x B. 470.x C. 525.x D. 535.x
Show Answer
Answer: D. 535.x
Explanation: The NVIDIA H100 GPU uses Hopper architecture and requires the latest drivers:
| GPU Model | Minimum Driver Version | Recommended Driver Version |
|---|---|---|
| A100 | 450.x | 525.x or later |
| H100 | 525.x | 535.x or later |
| H200 | 535.x | 545.x or later |
# Verify H100 driver installation
nvidia-smi
# Update driver
sudo apt-get update
sudo apt-get install nvidia-driver-535Driver version 535.x or later is recommended to fully utilize H100's key features (MIG expansion, Transformer Engine, etc.).
