4A0-108

The Nokia 4A0-108 exam, "Nokia Cloud Packet Core (CPC) Fundamentals," focuses on the fundamental concepts and technologies within Nokia's Cloud Packet Core (CPC) network solution. The main points covered include:

• Understanding of Cloud-Native Network Functions (CNFs): A core concept is grasping how network functions operate within a cloud environment, including virtualization, containerization (like Docker), and orchestration (like Kubernetes). You should understand the benefits and challenges of this approach compared to traditional network deployments.

• Nokia Cloud Packet Core Architecture: The exam requires a strong understanding of the overall architecture of the Nokia CPC solution. This includes its various components (like the virtualized EPC, IMS, and other network functions), how they interact, and the overall data flow.

• Virtualized Evolved Packet Core (vEPC) Components: This is a significant portion of the exam. You'll need to know the roles and functions of key vEPC elements such as the Access Gateway (AGW), Mobility Management Entity (MME), Serving Gateway (SGW), Packet Data Network Gateway (PGW), and their interactions.

• Virtualized IMS (vIMS) Components: Similar to the vEPC, understanding the different components of the virtualized IMS (IP Multimedia Subsystem) is crucial. This includes elements like the Call Session Control Function (CSCF) and other related functions.

• Network Slicing: Knowledge of network slicing, its benefits and implementation within the Nokia CPC architecture, is essential. This includes understanding how to create and manage different slices for various services and quality of service (QoS) requirements.

• Network Management and Orchestration: The exam tests your understanding of how the Nokia CPC network is managed and orchestrated. This may include tools and processes used for configuration, monitoring, and troubleshooting.

• Security Considerations: Security is paramount in any network. You'll need to know about security features and best practices within the Nokia CPC ecosystem.

In short, the Nokia 4A0-108 exam assesses your fundamental understanding of the Nokia CPC architecture, its key components, and its operation within a cloud-native environment. It emphasizes the practical aspects of deploying and managing a virtualized core network. The official Nokia training materials and practice exams are the best resources for detailed preparation.
