NCP-AIO Installation and Deployment Practice Question
When installing the NVIDIA GPU Operator, which namespace is typically used to ensure proper isolation and role-based access control?
⚠ Common exam trap
Candidates often install the Operator in the default namespace. This creates security risks and makes it difficult to apply specific RBAC policies or manage the lifecycle of the operator independently of applications.

Correct answer & explanation
✓
gpu-operator
Using a dedicated namespace like 'gpu-operator' is a best practice in Kubernetes. It isolates the operator's resources, permissions, and lifecycle from other cluster services. This separation allows for granular security policies, making it easier to manage access and ensuring that only authorized personnel can modify the operator's configuration, which is vital for maintaining the security and integrity of the GPU-enabled infrastructure in a production environment.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
default
Why it's wrong here
The default namespace is intended for general-purpose, non-critical workloads. Deploying infrastructure-level operators like the NVIDIA GPU Operator into the default namespace creates security risks and makes resource management significantly harder, as it mixes system-critical services with potentially unstable user-deployed applications, violating the principle of least privilege.
- ✓
gpu-operator
Why this is correct
Creating a dedicated namespace for the GPU Operator is standard industry practice. It provides logical isolation and allows administrators to apply specific RBAC policies to the operator's components, ensuring that the critical system-level software is segregated from general tenant workloads and other cluster services for better security posture.
- ✗
kube-system
Why it's wrong here
The kube-system namespace is reserved for core Kubernetes components such as the scheduler, controller manager, and DNS. Modifying or adding custom operators to this namespace is strongly discouraged as it interferes with cluster-core management and complicates upgrades, potentially causing instability in fundamental cluster operations.
- ✗
public-apps
Why it's wrong here
The public-apps namespace is not a standard Kubernetes convention and does not provide the administrative isolation required for system-level operators. Deploying the GPU Operator here would be confusing and fail to enforce the required security boundaries needed to protect the hardware-level integration components of the cluster.
Quick reference
Access Control Model Comparison
| Model | Acronym | Who Controls Access? | Best For |
|---|---|---|---|
| Discretionary Access Control | DAC | Resource owner | Small teams, file shares |
| Mandatory Access Control | MAC | System / security labels | Classified govt / military |
| Role-Based Access Control | RBAC | Administrator (via roles) | Enterprise environments |
| Attribute-Based Access Control | ABAC | Policy engine (user + resource attributes) | Fine-grained, dynamic policies |
| Rule-Based Access Control | RuBAC | System rules / ACLs | Firewall rules, network ACLs |
