How can I pass the 200-901 DEVASC test and become a Cisco Certified DevNet Associate?


Since you have chosen to become a Cisco Certified DevNet Associate, we are pleased to offer a thorough study guide for passing the 200-901 DEVASC exam. Let's start by providing some background information about Cisco certification. Cisco created a new automation certification pathway for developers and IT workers to enable task automation and improve network performance. DevNet is the name of this automation technique. Cisco is advancing networking in conjunction with this technical change by introducing new certifications for software development and expanding its well-established certification program.

The primary four DEVASC 200-901 course objectives

Reading and comprehending the course outline is the most crucial step in taking an exam like Cisco Certified DevNet Associate (200-901 DEVASC).


Cisco Platforms and Development Domain 1

  • creating a Python script that utilizes a Cisco SDK using the provided SDK docs
  • defining the capabilities of the platforms and APIs for Cisco network management (Meraki, Cisco DNA Center, ACI, Cisco SD-WAN, and NSO)
  • describing the possibilities of the Cisco platforms and APIs for computing management (UCS Manager, UCS Director, and Intersight)
  • describing the capabilities of the collaboration platforms and APIs from Cisco (Webex Teams, Webex devices, Cisco Unified Communication manager including AXL and UDS interfaces, and Finesse)
  • a description of Cisco security systems' and APIs' capabilities (Firepower, Umbrella, AMP, ISE, and ThreatGrid)
  • Understanding the dynamic interfaces and device-level APIs for IOS XE and NX-OS
  • Recognizing the appropriate DevNet assistance for a particular scenario (Sandbox, Code Exchange, support, forums, Learning Labs, and API documentation, model-driven programmability concepts (YANG, RESTCONF, and NETCONF) in a Cisco context
  • creating code to carry out a unique operation based on a set of regulations and given API reference materials like these:
  • Using Meraki, Cisco DNA Center, ACI, Cisco SD-WAN, or NSO to obtain a list of network devices
  • Hosting a list of clients and hosts observed on a network using Meraki or Cisco DNA Center and operating spaces, participants, and messages in W clients

Domain 2: Security and Application Deployment

  • defining edge computing's utility
  • Observing characteristics of various application deployment models (private cloud, public cloud, hybrid cloud, and edge)
  • Understanding the features of these forms of application deployment
  • Creating components for a CI/CD pipeline during application deployments is another thing to do.
  • construction of a Python unit test
  • interpreting a Dockerfile's contents
  • Using Docker images in a local developer environment follows.
  • observing issues with data management, storage, and transport encryption, as well as secret protection
  • illustrating the role of reverse proxies, DNS, load balancers, and firewalls in application deployment
  • highlighting the top OWASP threats (such as XSS, SQL injections, and CSRF)
  • making use of Bash commands (file management, directory navigation, and environmental variables)
  • recognizing the DevOps methods' guiding principles

Infrastructure and automation comprise Domain 3.

  • Differentiating between device-level and controller-level management
  • Utilizing and understanding the functions of network simulation analyst tools (such as VIRL and plats)
  • explaining the CI/CD pipeline's elements and advantages for infrastructure automation
  • describing infrastructure ideas as code
  • Give further details on the capabilities of technologies for automation like Ansible, Puppet, Chef, and Cisco NSO
  • identifying the process that a Python script using Cisco APIs, such as ACI, Meraki, Cisco DNA Center, or ESTCONF, is automating
  • describing the process that an Ansible playbook will automate (management packages, user management for services, basic service configuration, and start/stop)
  • observing the automation of the process using a bash script (such as file management, app install, user management, and directory navigation)
  • analyzing a RESTCONF or NETCONF query's output
  • Describe fundamental YANG models.
  • Using a unified diff to infer
  • defining the tenets and advantages of the code review process
  • interpreting the API call-filled sequence diagram

Domain 4: Basics of Networking

  • describing the use and application of MAC addresses as well as VLANs
  • defining the function and usage of the subnet mask/prefix, routes, and gateways
  • explaining the purpose of typical networking components (such as switches, routers, firewalls, and load balancers)
  • Understanding how to interpret a simple network architecture diagram that includes port values, switches, routers, firewalls, and load balancers
  • describing how a network device's administration, data, and control planes work
  • Give more details on how these IP Services work: DNS, NAT, SNMP, DHCP, and NTP
  • identifying typical protocol port values (such as SSH, Telnet, HTTP, Hythe TTPS, and NETCONF)
  • determining what is causing problems with application connectivity (NAT problem, Transport Port blocked, proxy, and VPN)
  • describing how network restrictions affect apps.

Conclusion

Candidates with the CCNA certification with a passing score on the Cisco 200-901 test are qualified for networking careers such as network administrators, entry-level network engineers, help desk representatives, and network support technicians. If you're starting in IT and want to increase your industry knowledge, the Cisco 200-901 is your best option.
