NCP-AII Question 130
Select 2You are managing an NVIDIA BlueField DPU in a data center environment. The goal is to isolate tenant workloads from the control plane to enhance security and performance. Which two steps should you take to configure and manage the BlueField DPU for this use case?
- A
Enable the BlueField DPU's hardware offloading capabilities for networking and storage tasks.
- B
Deploy the control plane software on the BlueField DPU while keeping tenant workloads on the host system.
- C
Configure BlueField in SmartNIC mode to offload infrastructure tasks from the host CPU.
- D
Disable SR-IOV (Single-Root I/O Virtualization) to ensure all traffic flows through the host CPU.
- E
Use DOCA (Data-Centric Open Accelerated) SDK to build and deploy security-focused applications on the DPU.
Show answer and explanation
Correct answers: A, C
Explanation
To enhance security and performance by isolating tenant workloads from the control plane, the BlueField DPU should be configured to offload infrastructure tasks (networking, storage, etc.) using its specialized hardware capabilities. SmartNIC mode is specifically designed for such use cases, enabling separation of tenant workloads and the control plane. This configuration ensures optimal resource utilization and workload isolation.
- A. Correct.
Enabling hardware offloading on the BlueField DPU allows the system to offload tasks like networking and storage, freeing up the host CPU for tenant workloads and improving performance.
- B. Incorrect.
Deploying the control plane software on the DPU while keeping tenant workloads on the host does not achieve workload isolation. Instead, it mixes control and tenant operations, which can degrade security.
- C. Correct.
Configuring BlueField in SmartNIC mode enables the DPU to act as a network and storage offload engine, isolating the control plane from tenant workloads and optimizing performance.
- D. Incorrect.
Disabling SR-IOV contradicts the goal of workload isolation, as SR-IOV is a key feature that supports efficient and isolated sharing of I/O resources among multiple tenants.
- E. Incorrect.
Using the DOCA SDK to develop applications on the DPU is not directly related to isolating workloads from the control plane. It is more suitable for building custom applications and services.
