Azure IoT Specialty exam certification Tips + Study Guide

Hello cloud marathoners,

Two weeks ago, I was able to clear the Azure specialty exam – “Azure IoT Developer” and get certified. More importantly, this was a good opportunity to learn about IoT technologies and services in Azure platform.

What is IoT?

An “Internet of Things” (IoT) device is typically made up of a circuit board with sensors attached that use WiFi to connect to the internet. Here are some examples of IoT devices and use cases:

  • A pressure sensor on a remote oil pump.
  • Temperature and humidity sensors in an air-conditioning unit.
  • An accelerometer in an elevator.
  • Presence sensors in a room.

The Azure Internet of Things (IoT) is a collection of Microsoft-managed cloud services that connect, monitor, and control billions of IoT assets. In simpler terms, an IoT solution is made up of one or more IoT devices that communicate with one or more back-end services hosted in the cloud.

Check out the following short video, if you never hear about applications of Internet of Things (aka, IoT).

Is there a comprehesive study guide to follow?

The short answer is YES!

As always start with simple and straight forward Microsoft Learn modules on IoT learning path. But that is not the only resource that i have used.

I personally found it very useful to check the Microsoft Tech community blog posts. The IoT sub-section has many tricks and trips and recommendations. Thus, check the following post that has very good information on exam resources:

AZ-220 IoT Developer Certification Study Guide – is an awesome post from Microsoft employee Paul DeCarlo. By following this post I got many answers on the following questions:

  • How do I know which topics to focus on, what skills does the AZ-220 exam measure?
  • Where can I learn how to apply the concepts measured on the AZ-220 exam in a practical / hands-on manner?
  • I prefer to learn at my leisure with video content, are there any resources that cover the materials in the official docs and Microsoft Learn that I can watch?
  •  Any thoughts on paid courses / practice exams, are there any recommendations?

Where can I get Azure IoT Samples in C# ?

I have used the following GitHub repo in order to get hands-on expereince with Azure IoT. Azure IoT Samples for C# (.NET)

What is next?

Check this awesome IoT Event Learning Path.

It is designed for Solution Architects, Business Decision Makers, and Development teams that are interested in building IoT Solutions with Azure Services. The content is comprised of 5 video based modules that approach topics ranging from IoT device connectivity, IoT data communication strategies, use of artificial intelligence at the edge, data processing considerations for IoT data, and IoT solutioning based on the Azure IoT reference architecture.

Conclusion

Thank you for reading this post till this point.

Please, feel free to share your experience, as i am planning to keep this post up to date with your valuable contributions going forward. #keeplearning

Exam Guide Tips AND prep resources: 2-in-1 sweet combo

My little intro – well, skip this as it might be boring πŸ™

Let’s start with a little bit of background to my somewhat unorthodox journey into Azure Developer cert way back in 2018.

Three years ago, I got a beta exam invite for Azure Core Developer (AZ-200) certification. At the time, there were no readily availiable study materials to learn from and prepare. My focus was on the exam objectives document, with a special highlight on Azure services that I did not have a chance to work with.

Long story short, at the end of the exam I did not know if it was a PASS βœ… or not ❌, as it was a beta exam. However, good and somewhat unexpected “pass news” with a cert email came back in 2 months. I was over the moon 🌜 and delighted to be one of the few candidates to succeed. Later, this exam was retired, as most cert nowadays…

Back to the current time, Feb 2021

Today, I was feeling excited & pumped to go after Azure Developer cert (AZ-204) πŸƒβ€β™‚οΈπŸš΄β€β™‚οΈπŸŠβ€β™‚οΈπŸ’ͺ – and yes, I posted earlier that I will share the result – either pass or fail.

Well, the good news is – I did not have to wait 2 months to learn the result πŸ˜ƒ It was a pass – and not an easy one though, as there were 60% more materials and more detail oriented questions on different inner workings of Azure services.

Let’s give a round of applause πŸ‘πŸ‘πŸ‘ to Microsoft Learn modules and Learning path tracks – as they are getting better and better – and help me to cover this material in a somewhat fun way….

How was my actual exam experience?

The overall experience was exciting 😲 and scary 😱 at the same time. Mainly, because of the two case studies appearing at different sections of the exam. Well, at the end of the exam I shared this non pleasant experience by providing feedback ✍. I think every exam participant should be willing to share their experience, as it will be a good set of metrics for exam creators to assess and modify the exam experience to make it better overall.

Speaking about the exam, I got approximately 50 questions❔; where two case studies contained approx. 5-7 questions each. My surprise was to discover πŸ‘€, one case study right in the beginning, and another one right at the end of the exam. It threw my timing a little bit off.

So, be prepared to save enough time for exam case studies (yes, there might be more than one, and I had three in the Microsoft exams last year), no matter what, as they consume a considerable chunk of your time and could cause your brain to start steaming ♨ – due to time constraints.

If you are a Cloud Solutions Architect (aka, CSA) you may find certain questions too technical in nature, like knowing the exact sequence of operations to place each task correctly. Well, if you never played with that specific feature then don’t panic. Just focus on the question and use your #quizskills. As an example: I had several educated guesses ⁉ – on what might be the right order of operations without knowing 100%.

In the real world, you could easily find your way with a quick search on your favorite engine… but an exam is an exam… and you are not penalized for wrong answers.

Good news is: a certain number of questions are high level, and your current CSA experience will be very handy; like assessing/suggesting the workload for the most effective Azure service or solution based on customer requirements.

Exam duration is180 minutes⏰ or 220 min including the feedback time. Generally speaking, this should be enough with a small caveat: You have to plan your time carefully and watch for the exact # of potential questions and remaining case studies of the exam. That said, there were several questions with true/false options, many drag-and-drop scenarios, and multi-select choices that seemed easy and tricky at the same time.

Microsoft Certified: Azure Developer Associate

Where should I start my Azure Developer journey?

The official exam page AZ-204 is a really good place to start. Followed by the suggested learning track and modules in the bottom of the page.

Microsoft Azure Data Engineer Certification Tips + Study Guide

Hello my friends,

Last week, I was able to knockout the second “Azure Data Engineer” exam and get the certification. Most importantly, I got a chance to have a deep dive into Azure Data technologies from a holistic solutioning perspective. The main focus areas of this certification are neatly visualized below:

Those exam objectives, are high level focus areas that cover DP-200 and DP-201 exams. The first exam is more technical and has focus toward implementation while the second one is shifting gears toward design and solutioning options based on project requirements.

As dealing with data solutions was not my primary work responsibility, I was really impressed by depth of service options, capabilities and tools that could accelerate many data solutioning projects.

Starting an “Azure Data Engineering” learning journey will help any cloud professional to get deeper understanding on designing different data solutions based on project requirements. In fact, it helped me to get a well informed understanding technical limitations in each solution; like deciding between different data processing and/or storage options and their respective security configurations. Well, enough about intro, let’s look into what it means to be an “Azure Data Engineer” πŸ˜‘πŸ€”

Azure Data Engineer vs Database Administrator

A Database Administrator’s (aka, DBA) job is to ensure everything is working smoothly with things like performance tuning and monitoring, data migrations of third party systems, performing backups, checking performance, and load balancing, and everything to do with databases operations. On the other hand, DBA could also perform data engineering tasks in a small or mid-size organisations.🀠

Azure data engineers are responsible for data-related implementation tasks that include provisioning data storage services, ingesting streaming and batch data, transforming data, implementing security requirements, implementing data retention policies, identifying performance bottlenecks, and accessing external data sources. They are responsible for data-related design tasks that include designing Azure data storage solutions that use relational and non-relational data stores, batch and real-time data processing solutions, and data security and compliance solutions.πŸ‘©β€πŸš€πŸ‘¨β€πŸŽ“

Getting ready for each exam πŸ“†

There is no right or wrong starting point with this certification. I would start with the one that you find more familiar. Here is the exam flow diagram from the official Microsoft learn website:

Exam study resources for DP-200: Implementing an Azure Data Solution

This exam really tests your ability to demonstrate good understanding of setting-up a data processing pipeline and configurations of each component. A lot of questions were on optimizing, operating, loading and reading data from Azure SQL DB and Synapse Analytics (formerly SQL DW), I found them tricky and quite challenging.

The DP-200 exam has around 40-48 questions and is somewhat similar to other Azure Associate exams. The exam duration is fixed around 180 minutes with additional 30 minutes for reading instructions, signing the non-disclosure agreement, and giving feedback to each question at the end.

Expect different types of questions (single choice, multi-choice, binary choice and sorting order) and one or two case studies.

Exam study resources for DP-201: Designing an Azure Data Solution

My exam experience with DP-201 was much smoother, as mainly questions were focused on design related topics and solutioning options. As an Azure Architect – you may find them familiar and a bit easier than the previous exam.

This exam was 150 minutes long and had 42 questions, with much more case studies (i got three on my exam). There were few questions with set of drop-down choices that were easy and tricky at the same time.

That is it folk, i tried to share and illustrate my exam experiences in this post. I hope you will find it helpful and apply to your “Data Engineer-ing” journey.

Please, feel free to share your experience or thoughts, as i am planning to keep this post up to date with your valuable contributions going forward. #keeplearning

Journey 2 RE-certification: AZURE SOLUTIONS ARCHITECT EXPERT

Over the weekend, I had a scheduled proctored exam AZ-301 Microsoft Azure Architect Design. Passing it would re-certify my credentials in Microsoft Certified: Azure Solutions Architect Expert, but most importantly up-skill my knowledge in recent changes of Microsoft Azure.

Actually, the first pre-requisite Expert Architect Technologies exam which I had, earlier in May, was not easy at all. The content of exam is quite BIG, in comparison what it used to be 2 years ago. It turned out to be true underestimate from me, when i failed my first attempt. The good or bad thing about this failed exam was the score – 679. I missed it with just one correct answer. Ah…

Anyway, repetition is the mother of perfection. If there is true perfection, it’s about getting ready, and doing something over and over again. Well, on the second attempt I was able to pass AZ-300 Microsoft Azure Architect Technologies much easier… If you curious about the score, it was in upper 900’s (where max is 1000).

Overall, Microsoft Expert exams are much harder (probably 3x times) to get prepared than the Associate one. Thus, I was pretty excited and nervous while going for the next exam Architect Design πŸ™‚ It turned out well this time, as I used those skills in my day-2-day work, so no surprises there…

By the way, the Microsoft also announced new exams (AZ-303 and AZ-304) for the Azure Solutions Architect certification. They are all in beta for now and there are no online training material yet. You can check these exams here Microsoft official post.

Earning the Azure Solutions Architect Expert certification demonstrates skills and knowledge to advise stakeholders and translate business requirements into secure, scalable, and reliable solutions. Candidates have advanced experience and knowledge across various aspects of IT operations, including networking, virtualization, identity, security, business continuity, disaster recovery, data management, budgeting, and governance – managing how decisions in each area affects an overall solution.

Microsoft Learn

There is an informative blog post by Chris Pietschmann, about the state of the current Microsoft Expert exams and how they are structured, if you are new to the Microsoft role based certifications i would recommend to have a look.

There is an informative blog post by Chris Pietschmann, about the state of the current Microsoft Expert exams and how they are structured, if you are new to the Microsoft role based certifications i would recommend to have a look.

Turning attention back to current Azure Architect exams, with a small detour, there are multiple overlapping topics between those two Expert exams. Completing one of them greatly help with the second one, as they share certain exam objectives.

Now, the list my study guides consisted from the followings:

Congrats to everyone, who already got the Azure Solutions Architect Expert badge and certifications! This is a good thing to accomplish.

For those who are planning to go with Azure Architect pass, I wish good luck in preparing and getting it done. It is going to be an interesting journey, a lot to learn, much more to practice and up-skill yourself to be better prepared for your next challenge!

Hopefully, my journey will be a tiny encouragement wave to start your own.
