Hence the need for IoT engineer is rising. <\/p>\n\n\n\n<p>IoT works on a simple principle: multiple devices are linked to one another, forming a network of devices linked via RFID (Radio Frequency Identification) systems, routers, actuators, and sensors (motion sensors, temperature sensors, moisture sensors, light sensors, etc.). These devices share data among themselves in order to give consumers more control and convenience when operating them.<\/p>\n\n\n\n<p><strong><em>Let us know look at the steps to become an IoT engineer!<\/em><\/strong><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>About IoT engineer\/ Developer<\/strong><\/h3>\n\n\n\n<p>The Microsoft Azure IoT engineer\/ Developer, AZ-220 exam is responsible for the implementation and coding required to build and manage an IoT solution&#8217;s cloud and edge components.

\/><\/a><\/figure><\/div>\n\n\n\n<h5 class=\"wp-block-heading\"><strong>Step 2 \u2013 Know about the Exam Format<\/strong><\/h5>\n\n\n\n<p>The exam has 40-60 questions, just like any other Microsoft Certification exam. Furthermore, all of the Microsoft AZ-220 exam questions are multiple-choice. Unlike any other certification, this exam is only available in English. There is a registration fee of USD 165. The candidate can also register for their exam with Microsoft partner Pearson Vue. Finally, in order to pass the AZ-220 exam, one must obtain a score of 700 or higher.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\"><strong>Step 3 \u2013 Know about &#8211; What&#8217;s in the Future?<\/strong><\/h5>\n\n\n\n<p>According to Statista, nearly 22 billion IoT devices were expected to be operational globally by the end of 2018. The number of IoT and connected devices will reach 50 billion by 2030! The salary of an IoT Engineer\/ Developer in India is determined by several factors, including the company&#8217;s size and reputation, the job role, location, and the candidate&#8217;s educational qualification, skill set, and work experience. <\/p>\n\n\n\n<p>However, rest assured that IoT engineer\/ Developers earn more than a decent yearly salary. According to the IoT India Salary Study 2017, IoT professionals in India earn nearly 76 percent more than IT professionals. While IoT professionals earn a median salary of Rs. 15.2 LPA, IT professionals earn a median salary of around Rs. 8.65 LPA.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\"><strong>Step 4 \u2013 Refer to the best Resources<\/strong><\/h5>\n\n\n\n<p>The levels of knowledge and comprehension of various resources differ. However, in academic life, revision should be done on a case-by-case basis. As a result, matching the type of revision you do on your source material is critical. Here are some resources to help you with your planning:<\/p>\n\n\n\n<h6 class=\"wp-block-heading\"><strong>Online study guides<\/strong><\/h6>\n\n\n\n<p>When it comes to online study guides, there are numerous options. These are ideal for certification exams. These are frequently among the most affordable study options. This section also includes product documentation. However, using the Microsoft AZ-220 study guide is one of the least structured study methods.<\/p>\n\n\n\n<h6 class=\"wp-block-heading\"><strong>Online Reference Courses<\/strong><\/h6>\n\n\n\n<p>There are numerous online, on-demand video services and courses available. Obviously, the price will differ depending on the source. These provide an excellent self-paced learning path that relies on audio and video rather than written books. While multitasking, these sources may be more natural to consume.<\/p>\n\n\n\n<h6 class=\"wp-block-heading\"><strong>Instructor-led Training (in-person or virtual)<\/strong><\/h6>\n\n\n\n<p>Attending in-person, instructor-led training is obviously the most expensive study path to take. This Microsoft AZ-220 training will provide you with a classroom full of students to work with and a dedicated trainer for the duration of the class. Certainly, if you have the time, this is the most effective training method, but it is also the most expensive.<\/p>\n\n\n\n<h6 class=\"wp-block-heading\"><strong>Practice Exams<\/strong><\/h6>\n\n\n\n<p>Taking practise exams is one of the most beneficial things you can do to prepare for your certification exam. Treat the IoT engineer\/ Microsoft AZ-220 practise exams as if they were real exams so you know what your strategy should be when the big day arrives. You should expect to fail your first practise exam. After that, go over each incorrect answer to identify your areas of weakness.

Knowing that you&#8217;ve done your best to prepare. While each question must be taken seriously. Furthermore, going into the exam stressed and overwhelmed increases your chances of failing. The goal is not perfection, but rather completion. Allow yourself some leeway by accepting that it&#8217;s normal to miss a question, to guess occasionally, or to be perplexed by the wording of a question. If necessary, you can always retake the exam.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-full\"><a href=\"https:\/\/www.testpreptraining.ai\/microsoft-azure-iot-developer-az-220-free-practice\" target=\"_blank\" rel=\"noopener\"><img decoding=\"async\" width=\"961\" height=\"150\" src=\"https:\/\/www.testpreptraining.ai\/blog\/wp-content\/uploads\/2022\/02\/How-do-I-become-an-IoT-engineer-3-2.png\" alt=\"\" class=\"wp-image-24193\" srcset=\"https:\/\/www.testpreptraining.ai\/blog\/wp-content\/uploads\/2022\/02\/How-do-I-become-an-IoT-engineer-3-2.png 961w, https:\/\/www.testpreptraining.ai\/blog\/wp-content\/uploads\/2022\/02\/How-do-I-become-an-IoT-engineer-3-2-300x47.png 300w\" sizes=\"(max-width: 961px) 100vw, 961px\" \/><\/a><\/figure><\/div>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Today, the Internet of Things (IoT) has applications in a wide range of fields, including smart homes (home automation), medical &amp; healthcare, environmental monitoring, agriculture, manufacturing, energy management, and long-term care, among others.
