You're deploying a BlueField-2 DPU in a cloud environment and need to ensure the integrity of the DPU's firmware. You want to verify that the firmware hasn't been tampered with. Which of the following methods provides the strongest level of assurance for firmware integrity?

• A.Verifying the SHA256 checksum of the firmware image against a known good value provided by NVIDIA.
• B.Checking the MD5 checksum of the firmware image against a known good value.
• C.Using a digitally signed firmware image and verifying the signature using NVIDIA's public key.
• D.Checking the file size of the firmware image against a known good value.
• E.Comparing the firmware version reported by the DPU with the version listed in the NVIDIA release notes.

After successfully installing the NVIDIA Container Toolkit and configuring the Docker runtime, you attempt to run a container that requires GPU access. However, the container fails to start with an error indicating that no GPUs are detected. You've verified that 'nvidia-smi' works on the host. Which of the following could be potential causes for this issue? (Select all that apply)

• A.The '-gpus all' flag was not included when running the 'docker run' command.
• B.The Docker daemon was not restarted after configuring the NVIDIA runtime.
• C.The NVIDIA drivers are not compatible with the kernel version running on the host.
• D.The NVIDIA Container Toolkit package is corrupted and needs to be reinstalled.
• E.The container image itself is missing the necessary CUDA libraries.

Consider a scenario where you want to reset your NVIDIAA100 GPU back to a non-MIG mode state after having previously configured MIG. Which of the following steps are required?

• A.Run 'nvidia-smi -set-mig-mode=disable -i O' followed by 'nvidia-smi -reset-default-mig-mode -i
• B.Run 'nvidia-smi -destroy-mig-config -i 0' , then run 'nvidia-smi -set-mig-mode=disable -i 0', and finally reboot.
• C.Run 'nvidia-smi -set-mig-mode=disable -i O', then run 'nvidia-smi -i 0 -migrr 0' , and finally reboot.
• D.Run 'nvidia-smi -set-mig-mode=disable -i O' and then reboot the system.
• E.Run 'nvidia-smi -set-mig-mode=disable -i , then power off the system and physically remove and re-install the GPU.

You are configuring a BlueField-3 DPLJ for a cloud-native application using Kubernetes. You want to offload container networking using OVS (Open vSwitch). Which of the following configuration steps are NECESSARY to integrate the BlueField-3 DPIJ with the Kubernetes cluster for network offload? (Select TWO)

• A.Install the Mellanox OFED drivers on all Kubernetes worker nodes.
• B.Manually create OVS bridges and vPorts on the BlueField DPU using 'ovs-vsctr.
• C.Configure the Kubernetes CNI (Container Network Interface) to use the OVS bridge managed by the BlueField DPIJ.
• D.Configure the BlueField DPIJ to act as a DHCP server for the Kubernetes pods.
• E.Deploy the NVIDIA BlueField Kubernetes Operator to manage the DPIJ lifecycle and networking configurations.

You are deploying a multi-tenant A1 infrastructure with strict isolation requirements. Which network technology would be most suitable for creating isolated virtual networks for each tenant?
