Microsoft Azure IoT Developer (AZ-220) Preparation Guide

Build a Study Routine

First and foremost it is utmost important to build some structure when it comes to studying, as well as prioritize your study hours. If you don’t, it’ll be way too easy to procrastinate or ignore what you need to do.  You must schedule your learning as per figure out when you can learn and research with least distractions. A quiet environment will help you concentrate and prepare well for the AZ-220 exam. 

Review Exam Topics

Microsoft certification exams are highly detailed examinations. So much so that even deeply skilled professionals have failed. So, try not to take it lightly. Each and every question is designed to challenge the candidate’s knowledge. Therefore, it’s not advisable to just guess and hope for the best. 

While you can’t comprehend and understand everything. However, you can get a head start with studying if you know the objectives and sub-objectives of each exam. All these are covered in the AZ-220 Course Outline mentioned above. Microsoft advertises the exam descriptions for all exams and lists their objectives. Nonetheless, each sub-objective will also have a set of skills that one will be tested on. So review this Official page as much as possible until you’re satisfied.

Gather all Learning Resources

Always, always, always get study materials from legitimate sources that are sanctioned by Microsoft. Microsoft issues its companion content online, and the candidate can seek out online resources and forums from people who have previously taken the exam. 

Many certified training companies have access to official Microsoft courseware. Further, this is aligned directly with the objectives of the exams. Role-based certification training courses, such as Azure training, will definitely help you dive deeper into a specific role while preparing for your exam. 

Online study guides

There are various sources when it comes to the online Microsoft AZ-220 study guide. These are best suitable for certification exams. These are often one of the cheapest options for study. The product documentation also falls under this section. But, this is one of the least structured methods to follow when studying.

Online Reference Courses

There are many online, on-demand video services and AZ-220 courses that can be viewed. Obviously, the cost can vary depending on the source. These offer a great self-paced learning path to follow using audio and video rather instead of written books. These sources can be more natural to consume while multi-tasking.

There are free video sources available on the Internet. Believe us, the internet is cluttered.  Their subscription services may cost between USD10 to USD 50 USD per month. There are many individual courses sold by various vendors as well. These vary in price from around USD10 to USD 300 per course.

Books are your Best Friends

Books are always a good learning resource to gain knowledge. Moreover, Microsoft has its own press store. So, never try to limit your knowledge. Therefore, we suggest going through the following AZ-220 books-

  • Internet of Things for Architects: Architecting IoT solutions by implementing sensors, communication infrastructure, edge computing, analytics, and security by Perry Lea
  • AI, IoT & the Intelligent Edge: Building Your Enterprise Tech Strategy by Daniel Sexton

Instructor-led Training (in-person or virtual)

Obviously, the most expensive study pathway to take is to attend in-person, instructor-led training. This Microsoft AZ-220 training will provide the candidate with a classroom full of students to attend along-side and a dedicated trainer for the duration of the class. Certainly, this is the most powerful training method if you can dedicate the time, but it will cost the most amount of money.

Instructor-led training can cost anywhere from around USD 30,000 to USD 50,000. These are intended to train a group of approximately 20 students at a time with an on-site instructor. This allows students to interact directly in-person with the instructor.

These classes will pool many students from many different clients together so that individuals and/or small teams can afford instructor-led training.

On the other hand, virtual delivery of instructor-led classes. Most of which are conducted over the Internet offer big cost savings. These do not require the trainer to travel, and the class can accommodate more than 20 students. 

Take Notes While Studying

“If in doubt, write it out.” Write down all technical detail you notice while studying for any Microsoft Certification exam. Since Microsoft’s exams are notoriously detailed. Hence this method can turn out to be a lifesaver. While what you write down might not be on the exam, it’s better to be safe than sorry. 

Practice Using the Technology

Hands-on experience will be invaluable as you take the exam. Instead of attempting questions about a theoretical practice you’ve only read about. With this, you’ll have real-life knowledge of what a chore does. But not everyone has access to technology like a sandbox data centre to experiment with.

Taking a course from a Microsoft-certified training corporation allows the candidate to test your knowledge of the product in a lab environment. Moreover, you can sign up for a trial account to get familiar with most Microsoft products, including Azure. 

Join Online Forums/Study Groups

Online forums and study groups are a great way to prepare for the AZ-220 exam. Therefore, feel free to get in touch with other candidates through study forums or online groups to ask a question related to the topic you’re having difficulty with.

However, it’s not something you have to join. It’s just something very subjective. Not to mention, these online groups help you stay equated with the other people who are also walking through the same path as yours. Moreover, you can also ask a question related to the topic you’re having difficulty with.

Take Practice Exams

One of the most worthwhile things you can do to qualify for your certification exam is to take practice exams. Treat the Microsoft AZ-220 practice exam like real exams so that you understand what your strategy should be when the big day comes. Expect to fail your first practice exam. Afterward, go through each wrong answer to determine your areas of weakness. FOR MORE PRACTICE SETS, CLICK HERE!
