To prepare for the Cisco 300-420 exam, candidates should have a strong understanding of Cisco networking technologies, as well as experience working with enterprise networks. Cisco offers a variety of training courses and study materials to help candidates prepare for the exam, such as self-paced e-learning modules, instructor-led training courses, and practice exams. Passing the Cisco 300-420 exam is a valuable credential for IT professionals who are looking to advance their careers in network design and architecture.
Commonly, the vendor offers an official exam guide for this and its other tests. These exam guides are the ideal way to understand the exam objectives in a detailed manner. For 300-420, you have the CCNP Enterprise Design ENSLD 300-420 Official Cert Guide: Designing Cisco Enterprise Networks as an option. Written by Steve Jordan and Anthony Bruno, this study guide has been recently published and is filled with relevant information about ENSLD 300-420 exam topics. Here, each chapter is packed with practical examples and relevant contexts. Plus, the systematic and logical coverage of enterprise designing concepts is noteworthy.
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:
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.
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.
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).
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.
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.

NEW QUESTION # 149
A company uses cloud-based applications for voice and video calls, file sharing, content sharing, and messaging. During business hours, these applications randomly become slow and unresponsive. However, other applications work smoothly with the current applied QoS polices. Which solution must the company choose to resolve the issue?
Answer: B
Explanation:
Explanation
using NBAR to identify application and bandwidth usage, then adjust existing QoS polices would be a more simple option. Of course, B is still ok if the network admin know all traffic and bandwidth consumption by other tools, say netflow.https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/qos_nbar/configuration/15-mt/qos-nbar-15-mt-book/n
