The practice test for the AWS Certified Solutions Architect Professional

Last weekend I was working on preparing a talk about AWS certifications (it looks like I will be presenting it at the upcoming [AWS Community Day Midwest](https://midwestcommunityday.com/)), and as part of that I was including sample questions for the different certifications.

AWS provides 10 sample questions for each certification, and the ones for the SA Professional certification can be found [on the certification page](https://aws.amazon.com/certification/certified-solutions-architect-professional/) alongside the exam guide.

As I hadn't actually gone through this version of the sample questions before, I decided to treat them like a mini test, and was fairly pleased to get 8 out of 10 right.

> In the past AWS did not provide the answers for these sample questions, so you could never be quite sure whether you had them right, but now all of them appear to have the answers and a short explanation (that's the really useful bit for questions you get wrong).

After that positive result, I decided to dive in and take the official practice test that you can register for at [http://aws.training](http://aws.training) and going into the certification sub-portal. The sample tests contain 20 questions and normally cost $20, but I had a coupon for a free practice test from a previous certification I'd taken.

The practice test gives you an hour to answer 20 questions, so 3 minutes for each. The full test lasts for 3 hours, and [apparently](https://help.acloud.guru/hc/en-us/articles/115001390094-AWS-Certification-Exam-FAQs) contains 75-80 questions, so you have less time per question. I've heard that a lot of people struggle with time on the test, so I tried to go through the questions quickly only pausing when I was unsure.

In the end I finished the 20 questions in about 35 minutes, and I felt pretty good about most of my answers and was surprised that some of the questions were relatively straightforward (of course what seems straightforward mostly had to do with which services I've been using for the last 5 years).

Unfortunately my confidence was somewhat misplaced as when I got the results I had only 65% correct (13/20). I had some doubts about a few questions (and I looked up a few things afterwards and knew where I'd gone wrong in those cases), but I think I was confident in answers to more than 13 of the questions.

Here's the breakdown that they sent me:

> Topic Level Scoring:
> 1.0  Design for Organizational Complexity: 50%
> 2.0  Design for New Solutions: 40%
> 3.0  Migration Planning: 75%
> 4.0  Cost Control: 50%
> 5.0  Continuous Improvement for Existing Solutions: 85%

Some of those (particularly Design for New Solutions) are a little painful.

Because it isn't obvious which questions I got wrong and why, that makes it harder to know where to focus my preparation. I think the reality is that I've got a lot of studying still to do if I want to go into the exam with a high chance of passing (as it currently stands I think I've got about 50/50 odds).

I will probably look into other sets of practice questions (even though I'm not convinced that all of them are very realistic) as it may be a good way to expose gaps in my knowledge for services that are likely to be on the test.

Hopefully the next post in the series will be to say how I passed the test. The testing centers are starting to re-open in Ohio, and while I'm in no rush to take the test, the virtual tests seem to have been a nightmare for some people (stories of people waiting hours for the proctor to start the test, and having to purge your room of extra monitors, paper etc.)
