This is the sixth and final in a series of articles on the six sections of Cisco’s DevNet Associate Exam DEVASC 200-901, which leads to the Cisco Certified DevNet Associate certification. This section covers Network Fundamentals.
Welcome to the final of the series of six articles intended to break down the blueprint sections for the DEVASC 200-901 exam. There are six major topic areas in this 120 minute exam. This article provides insight into the points you just can’t miss. This is a refresher section on Network Fundamentals so essentially all you have to do is dust off your CCNA or Network+ study material and review the following basic. It’s that simple. This section is worth 15% of the overall exam.
6.1 Describe the purpose and usage of MAC addresses and VLANs
6.2 Describe the purpose and usage of IP addresses, routes, subnet mask / prefix, and gateways
6.3 Describe the function of common networking components (such as switches, routers, firewalls, and load balancers)
6.4 Interpret a basic network topology diagram with elements such as switches, routers, firewalls, load balancers, and port values
6.5 Describe the function of management, data, and control planes in a network device
6.6 Describe the functionality of these IP Services: DHCP, DNS, NAT, SNMP, NTP
6.7 Recognize common protocol port values (such as, SSH, Telnet, HTTP, HTTPS, and NETCONF)
6.8 Identify cause of application connectivity issues (NAT problem, Transport Port blocked, proxy, and VPN)
6.9 Explain the impacts of network constraints on applications
Thank you for reviewing all of the six sections. Remember that all these exam topics are also covered in the DEVASC Developing Applications and Automating Workflows Using Cisco Core Platforms class. I hope these articles have given you insight to better understand the exam’s landscape. Good luck on your continued preparation and successful completion of the DevNet Associate (DEVASC) 200-901 exam.
