Authentic Nutanix Certification Exam NCP-CN Questions Answers

The NKPA course covers user authentication for NKP clusters as part of Day 2 operations, emphasizing integration with external identity providers (IdPs) to manage user access securely. NKP usesDex, an OpenID Connect (OIDC) identity provider, to facilitate authentication by acting as a connector between the Kubernetes cluster and external IdPs, such as LDAP, SAML, or OAuth-based systems.

The course explains that to set up user authentication, a Platform Engineer must configure aDex connectorto the user base’s identity provider. Dex integrates with the Kubernetes API server to enable OIDC-based authentication, allowing users to log in using their IdP credentials. The Nutanix Cloud Native (NCP-CN) 6.10 Study Guide states: “NKP supports user authentication through Dex, which provides OIDC integration with external identity providers, enabling single sign-on (SSO) for cluster access.” The process involves deploying Dex as a platform application, configuring the IdP connector (e.g., specifying client IDs, secrets, and endpoints), and updating the Kubernetes API server to use OIDC authentication.

Incorrect Options:

A. Enable Gatekeeper and create a connector to the user base’s identity provider: Gatekeeper is a Kubernetes policy engine used for enforcing admission control policies, not for authentication. The NKPA course does not associate Gatekeeper with user authentication.

B. Disable native NKP authentication, enable Traefik, and create a connector to the user base’s identity provider: Traefik is an ingress controller for managing external traffic, not authentication. Disabling native authentication is unnecessary, as NKP supports OIDC alongside native methods. The NKPA course does not mention Traefik in the context of authentication.

C. Create a MetalLB connector to the user base’s identity provider: MetalLB is a load balancer for bare-metal Kubernetes clusters, not an authentication component. This option is irrelevant, as per the NKPA course.

According to theNKPA 6.10 documentation, theFIPS Compliant Build featureis exclusively available forEnterprise tierlicensing. This ensures compliance with NIST security standards and provides hardened cryptographic capabilities throughout the Kubernetes cluster stack.

Exact extract from documentation:

“The FIPS-compliant build feature is included in the NKP Enterprise tier, enabling deployments in environments that require strict security compliance.”

Attaching an existing Amazon EKS cluster to NKP for fleet management involves integrating the cluster into NKP’s management plane, which requires specific preparatory steps. The NKPA course outlines that the first step is tocreate a service account with cluster-admin permissionsin the EKS cluster. This service account is used by NKP to authenticate and manage the cluster, enabling operations like monitoring, scaling, and application deployment.

The Nutanix Cloud Native (NCP-CN) 6.10 Study Guide explains: “To attach an external Kubernetes cluster, such as Amazon EKS, to NKP, a service account with cluster-admin role bindings must be created to allow NKP to interact with the cluster’s API server.” The service account is configured with a token that NKP uses to authenticate requests. The NKPA course provides detailed steps, including creating the service account, assigning the cluster-admin ClusterRole, and generating a token for NKP integration. This step is critical to ensure NKP has the necessary permissions to manage the EKS cluster.

Incorrect Options:

A. Configure a ConfigMap according to EKS configuration: While ConfigMaps may be used for specific configurations, they are not the first step for attaching an EKS cluster. The NKPA course prioritizes service account creation.

C. Configure HAProxy to get connected to EKS clusters: HAProxy is a load balancer, not required for attaching EKS clusters to NKP. EKS uses AWS-native load balancers, and NKP connects via the Kubernetes API.

D. Deploy cert-manager in the EKS clusters: Cert-manager is used for certificate management, not a prerequisite for attaching EKS clusters. The NKPA course does not list it as a required step.
