AZ-400 Exam Day Tips
Below are some of the Microsoft AZ-400 exam strategies and some recommendations that will help you.
- You can take the AZ-104 and AZ-900 examinations to accustom yourself to the Azure offerings’ services.
- Schedule the azure DevOps engineer certification exam at least 60-90 days in advance. If you have coupons from a learning partner, try to use them or keep an eye out for Microsoft’s open Cloud Skill Challenges.
- If you are giving a Virtual Exam for the first time, read the exam information provided by PearsonVUE to verify that your desk and workspace are clean before beginning the exam.
- The best time to schedule the AZ 400 certification exam is always a question. You can suit it according to you. If you’re an early bird, and your mind is free of the stresses of the day, give it in the morning. If you’re having trouble with wait times, you can make scheduling in the evenings or afternoons PST time zones.
- You will have access to a whiteboard where you can jot down exam-related ideas.
- Before the AZ 400 exam starts, you can adjust the brightness of your screen or go to Dark Mode according to your choice. Staring at a white screen can make it very challenging to focus. You can consider switching to dark mode from near the bottom left when you start.
- Use the AZ 400 certification Exam Outline to write down your target dates for each module and part to stay on track. For instance, you can choose a deadline and work backward to determine how much time you need to devote to each module and section.
AZ 400 Exam Retake Policy
The AZ-400 Exam Retake Policy is as follows:
- If a candidate fails on the first attempt, they must wait for 24 hours before retaking the exam.
- If a candidate again fails on the second attempt, then the candidate will have to wait for 14 days.
- A candidate will be given a maximum of five attempts to retake an exam in a year.
One of the new role-based Azure certifications, Azure DevOps Solutions, validates the competencies of Azure DevOps Professionals. AZ-400 exam can help you pave the way in your career and learn a new set of skills to hike your salary as well.
