Failing and Retaking the Exam
If you fail the exam, you can retake it whenever it is convenient for you. However, a fourteen (14)-day waiting period is required before retaking the exam. If you fail the second attempt as well, you may retake the exam after a waiting period of at least sixty (60) days. You will only be allowed three retakes, with the third one requiring a one-year wait.
Step 4 – Refer to the best Resources
Different resources have distinct knowledge and comprehension sets. In academic life, however, revision should be done on a case-by-case basis. As a result, it is critical to match the type of revision you do on your source material.
The official site visit
The exam’s official website contains information about the exam’s various technical aspects. The official website also mentions several resources, including the Professional Collaboration Engineer Practice Exam and the G Suite Administration Specialization. Google also provides a platform for hands-on exam practice. This exam is intended to assess technical skills relevant to the job role. In addition to being familiar with the day-to-day tasks performed by the G Suite administrator, use Qwiklabs’ hands-on labs to learn about G Suite integrations to advance your knowledge and skills.
The books club
You can use any book that you are familiar with and that is appropriate for your level of understanding. You can also refer to the Google Professional Cloud Network Engineer Books that Google has recommended.

Many trustworthy sources, such as online educational sites, provide high-quality content. Now you can take a free Google Professional Cloud Network Engineer Practice Exam!
Online trainings and instructor led courses
For preparation, you can choose between Google Professional Cloud Network Engineer Trainings and instructor-led courses. They are sufficiently interactive and provide a forum for proper discussion. They also provide relevant study material such as notes and recorded lectures to help make things clear.
Step 5 – Take the exam in accordance with the Expert’s Advice
A practice run or two, regardless of how you prepare for the Google Professional Cloud Network Engineer Exam, can help you in more ways than you might think. Taking a practice test is an excellent way to diversify your study strategy and ensure the best results possible for the real thing. GCP provides the Google Professional Cloud Network Engineer Practice Exam to candidates for them to gain an understanding of the pattern of questions asked. Analyzing your answers will help you identify areas where you need to focus more attention, as well as your alignment with the exam objectives.
When a larger number of people are involved, the chances of resolving an issue improve dramatically. Furthermore, multiple points of view make the material more dynamic. These discussions broaden the scope of the studies. Introverts, who might otherwise prefer to avoid discussions, are allowed to express themselves. Forums are excellent for fostering a sense of community, which is essential for understanding others.
