Skills measured
Cloud-Native & NCS Fundamentals (CaaS/Microservices)
Covers the foundations of cloud-native design in telecom environments, highlighting microservices architecture, containerization principles, and Containers-as-a-Service (CaaS) concepts. Introduces Nokia Container Services (NCS) positioning within the telco ecosystem, differences between VMs and containers, OCI image management, registries, and Kubernetes basics. Provides grounding in Day-0 setup, service models, and NCS terminology critical for managing CNFs.
NCS Architecture, K8s Control Plane & Platform Services
Explores the structural backbone of NCS, including Kubernetes control plane components (API server, etcd, scheduler, controller manager) and their mapping to telco-grade NCS deployments. Focuses on node roles, container runtime integration, networking/storage interfaces (CRI, CNI, CSI), and platform services such as ingress controllers, DNS, and service registries. Includes multi-tenancy, resource quotas, and platform lifecycle management.
CNF Lifecycle & Application Management (Helm/Operators/Day-0/1/2)
Provides deep insights into managing telecom containerized network functions (CNFs) across their full lifecycle. Covers CNF onboarding via Helm charts and Operators, Day-0 parameterization, Day-1 configuration using ConfigMaps and Secrets, and Day-2 operations such as rolling upgrades, blue-green deployments, and canary rollouts. Emphasizes high availability, scaling (HPA/VPA), workload scheduling, and performance-driven configuration for telco workloads.
Networking for Telco CNFs (CNI/Multus/SR-IOV/Service Mesh)
Focuses on networking models tailored for telecom-grade CNFs. Covers Kubernetes CNI plugins, multi-interface networking with Multus, SR-IOV for high-throughput/low-latency traffic, and integration of DPDK/OVS-DPDK. Explains service exposure (NodePort, LoadBalancer, Ingress), east-west and north-south traffic patterns, QoS enforcement, and service mesh adoption with Istio/Envoy. Includes advanced troubleshooting and performance tuning.
Storage & Stateful Telco Workloads (CSI/StatefulSets/Performance)
Addresses persistence and state management for telecom applications. Covers CSI drivers, persistent volumes/claims, StatefulSets for subscriber data and critical functions, topology-aware provisioning, and backup/recovery strategies. Focuses on latency-sensitive workloads such as UDR, UDSF, and subscriber DBs, including tuning for IOPS, NUMA alignment, and data consistency in distributed environments.
Security, Compliance & Supply Chain (RBAC/PSA/Secrets/Signing)
Examines the end-to-end security posture of NCS. Covers Kubernetes RBAC, Pod Security Admission controls, image signing and verification (Sigstore/Cosign), SBOM management, and container runtime security (seccomp, AppArmor, rootless containers). Discusses TLS/mTLS for CNF communication, secret encryption with KMS, zero-trust identity models, and regulatory compliance requirements such as ETSI NFV and 3GPP standards.
Observability, Troubleshooting & SRE (Metrics/Logs/Tracing)
Provides a holistic framework for monitoring and operating NCS platforms and CNFs. Covers observability pillars: metrics (Prometheus, custom exporters, p95/p99 latency), logs (EFK/ELK pipelines), and traces (OpenTelemetry). Teaches fault isolation using kube-events, node metrics, and CNI traces. Incorporates SRE concepts like SLOs, error budgets, chaos testing, and structured RCA methodologies for incident management.
CI/CD, GitOps & Policy-as-Code for NCS
Explores automation strategies for telco-grade CNFs. Covers pipeline tools (Jenkins, Tekton), GitOps with Argo CD, declarative desired state, and progressive delivery techniques (canary/blue-green). Includes policy enforcement via OPA/Gatekeeper and Kyverno, admission controllers, drift detection, and compliance-driven deployment governance. Focus on end-to-end lifecycle automation from build to production-ready deployment.
5G/Telco Integration on NCS (Core CNFs, DPDK/NUMA, Edge)
Details deployment of 5G Core network functions (AMF, SMF, UPF, NRF, PCF, CHF) and IMS CNFs on NCS. Explains workload tuning via CPU pinning, NUMA binding, hugepages, and real-time kernels. Discusses high-performance packet processing with DPDK/VPP, edge/metro cluster deployment, and integration with MANO systems and legacy VNFs. Includes performance benchmarking, interoperability, and slice-specific isolation.
Multi-Cluster, Edge, HA/DR & Platform Governance
Focuses on advanced operational governance for NCS at scale. Covers multi-cluster federation, lifecycle management via Cluster-API, high availability design (multi-zone control planes, quorum, etcd), and disaster recovery strategies (Velero, backup/restore, RPO/RTO alignment). Includes governance frameworks for capacity management, quotas, cost optimization (FinOps), compliance auditing, and upgrade orchestration.
Use of the Telecom - Nokia Container services (NCS) Test
The Telecom – Nokia Container Services (NCS) test is designed to evaluate a candidate’s expertise in deploying, managing, and optimizing containerized network functions within Nokia’s cloud-native ecosystem. As telecom operators transition from traditional infrastructures to virtualized and cloud-native networks, proficiency in NCS is becoming a critical skillset to ensure agility, scalability, and service reliability.
Hiring for this capability is essential because modern telecommunications demand seamless orchestration of containerized applications, integration with multi-vendor environments, and adherence to strict performance and security requirements. Organizations that lack skilled professionals risk operational inefficiencies, reduced network resilience, and slower time-to-market for new services. This assessment helps employers identify candidates with the technical and operational knowledge to deliver high-quality telecom solutions in dynamic environments.
The test covers skills across container lifecycle management, orchestration, cloud-native deployment practices, security and compliance considerations, and troubleshooting within the Nokia NCS framework. It also assesses candidates’ ability to support network evolution strategies, optimize resource utilization, and align with industry standards for 5G and beyond.
By incorporating this test into the hiring process, employers can ensure they select professionals capable of driving digital transformation, maintaining competitive service delivery, and strengthening operational efficiency in the rapidly evolving telecom landscape.
Who is this test for?
The Telecom – Nokia Container Services (NCS) test is relevant across telecom and cloud industries, assessing candidates’ ability to manage containerized network functions, optimize deployments, and ensure secure, scalable operations—crucial for roles in engineering, operations, and digital transformation.
