WGU D415 OA Tips for Success in Software Defined Networkingđšđ»âđ«
Preparing for the Software Defined Networking D415 OA requires not just understanding the material but also strategizing how you approach the exam. Here’s some advice on how to maximize your chances of success, based on insights from students who have taken the exam and performed well.
Understand the Complexity of the PA and OA
The first thing you need to know is that the Pre-Assessment (PA) and the Objective Assessment (OA) are quite aligned in terms of complexity and the types of questions youâll encounter. This means that if you can do well on the PA, youâre likely in good shape for the OA. However, donât take this as a sign to relax. Use the PA as a diagnostic tool to identify any weak areas where you need further review. Focus on understanding the reasoning behind the “reasonable” answers in the PA. The OA will often present you with two reasonable and two unreasonable answers per question, so being able to distinguish between them is crucial.
Master the Terminology
In particular, terminology is a focus of this course. It is advisable that you familiarize yourself with many acronyms and technical terms you are likely to encounter, thus do not neglect this factor. Especially NFV (Network Function Virtualization), VNF (Virtualized Network Function), VNFM (Virtual Network Function Manager), VNFI (Virtual Network Function Infrastructure), and CVSS (Common Vulnerability Scoring System). These terms are not only incorporated in the questions but also offered in the general theme of the subjects tested in the exam.
If you are not therefore familiar with some of the basic network security principles such as, if you have not taken a CCNA or if you do not have much experience working with firewalls, then spend some time revisiting these areas. The OA prescribes the use of certain elements of networking; especially the OSI model layers 1 through three; so you need to have a good grasp of these before progressing.
Focus on Specific Topics
Certain topics are emphasized more heavily on the OA, so itâs important to know where to focus your efforts. Youâll likely encounter multiple questions on OpenStack, the differences between SDN vs. NFV, and the specifics of NIST 800-53 and NIST 800-125B. Understanding these frameworks and standards will give you an edge. Additionally, be sure to review the differences between Southbound vs. Northbound interfacesâa topic that can be confusing but is crucial for understanding SDN architecture.
Network security is another area where youâll want to be particularly sharp. Expect questions related to IDS/IPS (Intrusion Detection System/Intrusion Prevention System), firewalls, and other security-related topics. Even if these arenât your strongest areas, make sure you have a basic understanding, as these questions can be the difference between passing and failing.
Leverage External Resources
While the course materials are essential, donât forget to supplement your study with external resources. Watching videos on platforms like Pluralsight and Udemy can provide additional explanations and examples that may clarify difficult concepts. Focus especially on videos that cover the acronyms and security basics mentioned earlier. Additionally, reviewing what Open Platform and open source mean in the context of SDN will help you tackle related questions with confidence.
Lastly, donât underestimate the value of using Google to fill in gaps in your understanding. For example, the NIST standardsâNIST 800-125B and NIST 800-53âwerenât deeply covered in the course material, but a quick search can provide you with the insights you need to understand these standards more fully.
Final Thoughts
In summary, preparation for the OA in Software Defined Networking D415 involves a combination of mastering terminology, understanding key topics, and leveraging external resources to fill in any knowledge gaps. By focusing on the areas outlined here and making sure youâre comfortable with the reasonable answers in the PA, youâll be well-prepared to tackle the OA with confidence.
