The Cisco Certified Network Professional (CCNP) certification is a significant milestone for IT professionals looking to advance their careers in networking. The CCNP Enterprise (EN) certification is essential for those aiming to work with enterprise-level network infrastructures. One of the core exams required to achieve the CCNP Enterprise certification is the 350-401 ENCOR v1.1 exam, which covers a broad range of networking topics. This exam tests candidates on the skills and knowledge necessary to implement, configure, and troubleshoot enterprise networks.
In this article, we will provide a comprehensive overview of the key topics covered in the Cisco CCNP ENCOR (350-401) exam, helping you understand what to expect, what to study, and how to best prepare for this certification.
1. Network Architecture (25%)
The Network Architecture section of the ENCOR exam focuses on foundational network design principles, including how to configure and optimize network devices to meet business requirements. Topics include:
a) Enterprise Network Design
- Understanding topology and scalability for enterprise networks, including considerations for high availability.
- Designing for resiliency, particularly using concepts like redundant paths, and link aggregation.
- The use of Software-Defined Networking (SDN) in network architectures.
- Integration of cloud services and hybrid IT infrastructures.
- The design and deployment of WAN technologies, including MPLS and VPNs.
b) Design Principles
- Hierarchical network design, which includes the core, distribution, and access layers.
- QoS (Quality of Service) mechanisms for traffic management.
- Design for security and scalability.
A solid understanding of these principles will ensure that the network is not only efficient but also reliable and scalable.
2. Network Virtualization (25%)
Network virtualization is one of the most rapidly evolving aspects of modern networking. The ENCOR exam places significant emphasis on the skills required to design, implement, and troubleshoot virtualized network environments. Key topics include:
a) Virtual Routing and Forwarding (VRF)
- Configuring and troubleshooting VRF Lite for isolating traffic between different virtual networks.
- Implementing and maintaining routing protocols within a VRF context.
b) Software-Defined Networking (SDN)
- Understanding SDN concepts, including the role of a controller and how it interacts with data planes and control planes.
- Introduction to Cisco DNA Center for automation and orchestration.
c) Network Functions Virtualization (NFV)
- The concept of decoupling network functions from hardware and deploying them as software on commodity hardware.
- Integration of virtualized network functions (VNFs) into enterprise networks.
The understanding of virtualization is essential for managing large-scale, flexible, and cost-effective networks. As enterprises move toward cloud solutions and hybrid environments, these skills are increasingly in demand.
3. Infrastructure (30%)
The Infrastructure section of the exam delves deep into the core technologies and protocols required to build and maintain enterprise networks. Candidates must demonstrate expertise in several key areas, such as:
a) Layer 2 Technologies
- Configuration and troubleshooting of Ethernet and VLANs.
- Implementing Spanning Tree Protocol (STP) for preventing loops in Layer 2 networks.
- Concepts such as VTP (VLAN Trunking Protocol) and Trunking.
b) Layer 3 Technologies
- IP addressing schemes, including IPv4 and IPv6.
- Routing protocols such as OSPF, EIGRP, and BGP, and how to implement and troubleshoot them.
- Route redistribution, and understanding routing loops and path selection.
c) Wireless Networking
- Configuring and troubleshooting enterprise wireless networks, including 802.11 standards.
- Cisco Unified Wireless Network (CUWN) components, including access points, controllers, and WLCs (Wireless LAN Controllers).
- Concepts such as SSID, security protocols, and RF (radio frequency) management.
d) IP Services
- DHCP and DNS configurations and troubleshooting.
- Implementing NAT (Network Address Translation) and PAT (Port Address Translation) for managing IP address assignment and traffic routing.
- SNMP for monitoring network devices SPOTO.
This section is arguably the most technical and hands-on, as it focuses on the practical implementation of network services that are critical to enterprise environments.
4. Security (15%)
With security being one of the most important concerns in networking, the Security section of the exam tests your ability to secure enterprise networks. Key topics include:
a) Network Security Fundamentals
- Implementing Access Control Lists (ACLs) to restrict network traffic.
- Configuration and use of VPNs, particularly site-to-site and remote-access VPNs.
- Configuring firewalls and intrusion prevention systems (IPS).
b) Authentication, Authorization, and Accounting (AAA)
- Configuring AAA protocols using RADIUS and TACACS+ for user authentication and network access control.
- Implementing and managing 802.1X for network access control.
Network security is paramount in today’s threat landscape, and candidates are expected to demonstrate the ability to secure enterprise environments through proper configuration and monitoring techniques.
5. Automation and Programmability (15%)
The final section of the ENCOR exam covers network automation and the growing role of programmability in networking. As networks become more complex, automation tools are critical for managing, maintaining, and optimizing network operations. Key topics include:
a) Network Automation Basics
- Understanding the principles of network automation and configuration management.
- Introduction to Python scripting for network automation.
- Using Ansible and Cisco APIs to automate network tasks and configurations.
b) Cisco DNA Center and Meraki
- Cisco’s DNA Center for automation and orchestration, including the use of Cisco Intent-Based Networking (IBN).
- Cisco Meraki for cloud-managed network devices and simple, scalable network deployments.
c) REST APIs
- The use of RESTful APIs to manage devices and services across a network.
- Scripting with REST API calls to automate routine tasks.
Automation and programmability have become vital skills for modern network engineers, allowing them to improve efficiency, reduce manual errors, and better support large-scale network environments.
Preparing for the Cisco CCNP ENCOR Exam
Successfully passing the 350-401 ENCOR exam requires a combination of theoretical knowledge and practical experience. Here are a few tips for preparation:
- Study Cisco’s Official Materials: Cisco provides official study resources, including books, courses, and practice exams, which are highly recommended for preparing for the exam.
