Cisco 300-420: Skills outline

Cisco 300-420 is a certification test that evaluates the individuals’ understanding of a wide range of knowledge areas. The skills measured in this exam are combined in various objectives, which are enumerated below:

  • WAN for Enterprise Networks (20%)

    This area evaluates one’s skills and knowledge of building frameworks, which make network communication resources and services available to end-users and systems. The questions under this objective also require that the students be able to compare WAN connectivity options, design site-to-site VPN, and design Cisco SD-WAN architecture. It is also important to know about failover, backup connectivity, multihomed, and single-homed.

  • Advanced Addressing and Routing Solutions (25%)

    Within this topic, the applicants are required to demonstrate their knowledge of advanced addressing & routing solutions. This means that they need to be well conversant with creating stable, scalable, and secure routing designs for different routing protocols, including EIGRP, IS-IS, OSPF, and BGP. They should also be conversant with IPv6 migration strategies that include Boundaries, Native, and Overlay.

  • Advanced Enterprise Campus Networks (25%)

    In the framework of this knowledge area, the learners are expected to show their competency in designing campus networks for high availability, designing campus Layer 2 and multicampus Layer 3 infrastructures. The potential candidates should also know about SD-Access architecture and SD-Access fabric design considerations for both wired and wireless access.

  • Network Services (20%)

    To answer the questions in this topic, the individuals should be able to demonstrate that they have the relevant knowledge and are capable of selecting and employing the most appropriate quality strategies, which will help meet the customer’s requirements. Other skills under this section include describing network management techniques, designing multicast services (MSDP, SSM, PIM bidirectional), and describing multicast routing concepts (RPF, source trees, shared trees, and rendezvous points).

  • Automation (10%)

    This domain is all about testing the applicants on their knowledge of various data model sets that enable service providers to effectively and actively manage the networks of their end-users. In the framework of this subject, they need to demonstrate their competency in comparing dial-in and dial-out approaches to model-driven telemetry, describing the effect of model-driven telemetry on the network, differentiating between RESTCONF and NETCONF, choosing the right YANG data model set according to the requirements and choosing the right QoS strategies to meet the requirements of a customer.

Further CCIE Certification Path

Acquiring the CCNP Enterprise certificate makes one eligible for the expert-level ones such as CCIE Enterprise Wireless and the CCIE Enterprise Infrastructure. The core test 350-401 is also one of the two requirements for these certifications, so the only step remaining is to pass one lab exam for any of the mentioned options. Both of those tests are 8 hours long and mostly assess one's practical competence.

The Cisco 300-420 exam evaluates the skills and knowledge of the candidates of enterprise design, including advanced addressing & routing solutions, WAN, advanced enterprise campus networks, SDA, as well as network & security services. This is a concentration test required for obtaining two certificates, and namely CCNP Enterprise and Cisco Certified Specialist – Enterprise Design. Please note that you also have to pass the core exam, which is Cisco 350-401. After that, you can add these certifications to your CV and demonstrate your expertise in the field of enterprise networking solutions.

The Cisco 300-420 exam is one of the requirements for the CCNP Enterprise certificate. Since candidates can choose their certification path according to their area of interest, those aiming to design Cisco enterprise networks should choose to take 300-420 test for sure. It validates one's ability to successfully handle different networks, perform advanced routing and addressing, work with WAN, ensure security, and many more.
