You are managing a Kubernetes cluster running AI training jobs using TensorFlow. The jobs require access to multiple GPUs across different nodes, but inter-node communication seems slow, impacting performance.
What is a potential networking configuration you would implement to optimize inter-node communication for distributed training?

• A.Increase the number of replicas for each job to reduce the load on individual nodes.
• B.Use InfiniBand networking between nodes to reduce latency and increase throughput for distributed training jobs.
• C.Configure a dedicated storage network to handle data transfer between nodes during training.
• D.Use standard Ethernet networking with jumbo frames enabled to reduce packet overhead during communication.

An administrator is troubleshooting issues with NVIDIA GPUDirect storage and must ensure optimal data transfer performance.
What step should be taken first?

• A.Check for compatible RDMA-capable network hardware and configurations.
• B.Increase the GPU's core clock frequency.
• C.Upgrade the CPU to a higher clock speed.
• D.Install additional GPU memory (VRAM).

What should an administrator check if GPU-to-GPU communication is slow in a distributed system using Magnum IO?

• A.Disable InfiniBand to reduce network complexity.
• B.Limit the number of GPUs used in the system to reduce congestion.
• C.Increase the system's RAM capacity to improve communication speed.
• D.Verify the configuration of NCCL or NVSHMEM.

You are tasked with deploying a DOCA service on an NVIDIA BlueField DPU in an air-gapped data center environment. The DPU has the required BlueField OS version (3.9.0 or higher) installed, and you have access to the necessary container image from NVIDIA's NGC catalog.
However, you need to ensure that the deployment process is successful without an internet connection.
Which of the following steps should you take to deploy the DOCA service on the DPU?

• A.Install Docker on the DPU, pull the container directly from NGC, and run it using `docker run' with appropriate environment variables.
• B.Use the host system's Docker engine to pull the container image and deploy it on the DPU via SSH.
• C.Pull the container image from NGC using Docker and modify the YAML file before deployment.
• D.Manually download the container image and YAML file beforehand, transfer them to the DPU, and deploy using Kubernetes with standalone Kubelet.

You are managing a high availability (HA) cluster that hosts mission-critical applications. One of the nodes in the cluster has failed, but the application remains available to users.
What mechanism is responsible for ensuring that the workload continues to run without interruption?

• A.Manual intervention by the system administrator to restart services.
• B.Load balancing across all nodes in the cluster.
• C.The failover mechanism that automatically transfers workloads to a standby node.
• D.Data replication between nodes to ensure data integrity.
