Published: 2023-01-25 12:39:25

While I was preparing for the Elastic Certified Engineer exam, I googled about mock practice tests and chanced upon this [excellent blog series]( https://medium.com/kreuzwerker-gmbh/elastic-certified-engineer-exam-what-to-expect-and-how-to-rock-it-cf409ed48d7b) of 4 tests.(Scroll to the bottom of the blog for links).


![Links to my blog series of exercises:](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/74h39wsfzzk6rxe7kz4l.png)


Attempting the exercises in these links did wonders to my confidence as I found lapses in my preparation strategy, got a chance to correct them and also got exposure to the questions and how to answer them. 

As for the format, while it can be found from Rich Raposa’s [webinar](https://youtu.be/9UpB-s_ZfNE?t=1452), the webinar tells you what to expect but attempting the mock exercises actually gives you a **_feel_** of the exam which makes a difference. 

From the exercises, the [first part]( https://medium.com/kreuzwerker-gmbh/exercises-for-the-elastic-certified-engineer-exam-deploy-and-operate-a-cluster-b06741760d47) is about deploying and operating a cluster. The first exercise – configure the nodes to avoid split brain - is no longer on the agenda so that can be skipped. Same way exercise 2 can be skipped as well. Exercise 3 is about optimization and could help you with Cluster Management section e.g. diagnose shard issues and repair a cluster’s health. Exercise 4 is about snapshots, cross-cluster search which again comes under Cluster Management so both exercise 3 and 4 are helpful.

The [second part]( https://medium.com/kreuzwerker-gmbh/exercises-for-the-elastic-certified-engineer-exam-store-data-into-elasticsearch-cbce230bcc6) is pretty relevant as it covers the topics of data management – index, templates (index and dynamic) and also data processing – reindex, ingest pipeline, painless scripting. One thing to note is that the exam can combine multiple objectives into one question. E.g. a question on re-index could also include ingest pipelines. Do attempt all the exercises in this post.

The [third part]( https://medium.com/kreuzwerker-gmbh/exercises-for-the-elastic-certified-engineer-exam-model-data-into-elasticsearch-5eb69086cdaa) covers mapping and text analysis which would be under Data Processing Category. This is very important and would help to attempt all the exercises here. Note that this does _**NOT**_ have exercises for `Runtime` fields. 

The [final part]( https://medium.com/kreuzwerker-gmbh/exercises-for-the-elastic-certified-engineer-exam-search-and-aggregations-1eefcfb6e992) covers exercises for Search and Aggregations and forms a very important part of exam preparation. One thing to note is: Pipeline and Matrix aggregations don’t look to be in the exam agenda. Please skip whatever doesn’t conform to the agenda. In case of any doubts about whether a particular topic is on exam agenda or not, just drop an email to certification[at]elastic[dot]co. The Elastic Certification team is pretty responsive and helpful. 

Final Note: These exercises are excellent to boost your preparation strategy and level up your confidence but do _**NOT**_ cover all the topics so you'll likely need mock exercises from other sources for the missing topics.
