Automation

This section makes up 10% of the whole content and requires that the students possess an understanding of the following processes:

• Distinguishing between NETCONF & RESTCONF;
• Explaining the influence of model-driven telemetry on networks such as periodic publication and on-change publication;
• Selecting the appropriate YANG data model set to meet the requirements;
• Comparing the dial-in and dial-out techniques to model-driven telemetry.

Topics of Cisco 300-420 Exam

The Cisco 300-420 certification exam validates the students’ knowledge of enterprise design. It covers a wide range of subject areas, such as advanced addressing & routing solutions, security services, WAN, advanced enterprise campus networks, SDA, and network services. The breakdown of these topics into the components of skills to be measured in the test is as follows:

Advanced Routing and Addressing Solutions

About 25% of the exam content is covered in this domain, and the candidates have to perform their skills in the following tasks:

• Creating the structured addressing strategies for both IPv6 & IPv4;
• Developing the scalable, stable, and secure routing design for EIGRP, IS-IS, BGP, OSPF.

As we all know, certificates are an essential part of one's resume, which can make your resume more prominent than others, making it easier for you to get the job you want. For example, the social acceptance of Cisco certification now is higher and higher.

Objectives of 300-420 Test

There are various topics that are included in the exam and they are:

• Advanced Enterprise Campus Networks (25%).
This part of the exam content measures one's skills in designing campus networks for high availability and knowledge of techniques for platform abstraction, graceful restart, etc.; designing campus Layer 2 infrastructures and multicampus Layer 3 ones, including route summarization, VRFs, convergence, etc.; describing SD-Access Architecture as well as SD-Access fabric design for wireless and wired access.
• Enterprise Networks and WAN (20%).
This section addresses the following areas: comparison of WAN connectivity options (DWDM, Layer 2 VPN, 4G/5G, Metro Ethernet, etc.); designing site-to-site VPN, including dynamic multipoint VPN, Ipsec, GRE, and others; designing high availability for enterprise WAN (failover, backip connectivity, etc.); Cisco SD-WAN architecture (on-boarding, security, control plane, and more); Cisco SD-WAN design considerations (redundancy, security design, overlay design, and others).
• Automation (10%).
The Automation domain includes things like choosing the correct YANG data model taking current requirements into account; differentiating between IETF, Cisco native YANG models, and Openconfig as well as between RESTCONF and NETCONF; understanding the impact of model-drive telemetry, covering on-change and periodic publications; comparing dial-in and dial-out approaches to model-drive telemetry.
• Network Services (20%).
The last domain focuses on the ability to choose proper QoS strategies, designing network management techniques; designing end-to-end QoS policies covering shaping, queuing, marking, and more; describing multicast routing concepts, and creating multicast services, including MSDP, SSM, and PIM bidirectional.
• Advanced Address and Routing Solutions (25%).
This domain mainly focuses on creating structured addressing plans for IPv4 and IPv6; creating scalable, stable, and secure routing designs for IS-IS, EIGRP, OSPF, and BGP, including route filtering, load sharing, address families, path preference attributes, and route reflectors; determining IPv6 migration strategies, involving native, boundaries, and overlay.
