How to prepare AD0-E702 Adobe Certified Professional Exam

I will discuss how to start preparation for AD0-E702 Adobe Certified Professional exam (earlier Magento 2 associate developer exam) on right track. Though it's the first certification in the Adobe Magento world, it doesn't mean anyone can participate in the exam with unplanned preparation and pass it. Similarly, we can't predict a great experience developer can just seat in the exam and will be able to clear, without any preparation of the same. What's matters is the preparation of relevant topics and most importantly the latest topics.

Now the question is if the preparation is the key factor, then how to start the same? Well, here are the steps you just need to follow to prepare AD0-E702 Adobe Certified Professional exam:

Go through Magento2 latest devdocs:

You should start from Magento 2 devdocs to understand basic concept of development. Try best to understand topics like theme, layout XML, and templates first. Also, I would suggest going through "Theme development best practices" in there. Note that you don't need to go through all the topics there. Only cover the required topics that are under this certification exam. Once previous topics are covered, you should start on to the Module development basic concepts. For this i would suggest to go through this video tutporials in the magento2 website Magento2 fundamentals video courses
Except for frontend UI parts like CSS & Javascript, complete the rest of the video courses. Try to understand first the theoretical parts, and if possible note down the important/highlighted points. Might be you don't understand the things for now, but it will be helpful later when doing the practical and after installing the M2 software.

Install Magento2 software in your computer

Now it's time to start the actionable part. Download Magento2 the latest version and install it on your desktop/laptop. It is important to understand the generation of the files while installing them. Once the installation is done, go through some files which hold the database information under the app/etc/. You should also try to understand all the CLI commands which are used to deploy the application.

Understand Magento2 admin-panel configurations

Once the installation is successfully done, start exploring the admin-panel. Here is the thing which has more priority as per the certification exam:

Store > Configuration, Customer and its various attributes in the edit page, Store > All Store to create and manage various store views, Marketing tab pages, Content > Theme Configuration to apply themes, logo, haeder, footer etc..

Understand Magento2 code structure

The code structure is to basically understand the module and theme file structure. You should google to know how you can create a new module, what are the mandatory/required files and optional files, and how it is registered in the system, etc. Try to create a new page that touches modules basic components like a controller, layout, template, block, and ViewModel. note that db_schema is an important part when using the CRUD which involves the Model concept. Explore more on these related topics like Perform common database operations using deb_schema, data patches, schema patches, etc.

Magento2 admin configurations, examtask.com

We often want to know about the exam difficulty level, important topics, prerequisites, etc. Because knowing the syllabus enables you to focus on the precise topics. This exam is basically designed to validate the Magento core level concept which is required when you initiate your carrier as a Magento developer in the IT field.

Difficulty level:

The exam difficulty level is moderate. Can be measured 4 out of 10 in digits. When you start your career you might have observed it more difficult. Let me explain how you can prepare for your exam easily in such a case.

Suppose you are creating a new Magento theme to understand its flow. You will google and start copying the codes in your theme files, and ready the theme after some time. But note that it is not sufficient as far as the exam is concerned. You must understand the purpose. More specifically file structure, file names, how new themes get registered in the Magento system, and how templates and layouts are linked to view level. etc. The same to be considered when you developing a new module, like how to create table, create model, collection and controller

This should be sufficient to get the basics of Magento2 from an exam point of view.

Important topics:

Here are the topics which are covered in this exam. Each topics have its cut off marks.

Customizing Magento UI
Request Flow Processing
Developing with adminhtml
Working with databases in Magento
Customizing Magento Business logic
Magento Architecture & Customization Techniques

Customizing the Magento UI" (15%)

Demonstrate the ability to customize the Magento UI using themes

Demonstrate the ability to customize the Magento UI using themes. When would you create a new theme? How do you define theme hierarchy for a project?
Basically, the theme is needed/created when you are asked to provide a dedicated view of the Magento store. The main intention of creating a new theme is to have the template structure different. Magento core has 2 themes "blank" and "luma"(default one) for the frontend and 1 theme: backend for admin-panel. Now for the interest of a new look and feel, you need to create a new theme.
Demonstrate an ability to create UI customizations using a combination of a block and template

How do you assign a template to a block? How do you assign a different template to a native block?
Ans: phtml templete is assigned to block with help of layout xml. for different template to a native block, child bocks are used inside parent block. For example in the homepage, main template file in 1-column.phtml, but inside that lots of template are rendered like headers, logo, menu, minicart, content and footer.
Example:

Identify the uses of different types of blocks

When would you use non-template block types?

Ans: Usage of different type of block: Template blocks, Non-template blocks, reference blocks.
Non-template block is used when it can render html with arguments only. For example:

                    <block class="Magento\Framework\View\Element\Text" name="store.links" group="navigation-sections">
                    <arguments>
                    <argument name="title" translate="true" xsi:type="string">Account</argument>
                    <argument name="use_force" xsi:type="boolean">true</argument>
                    <argument name="text" xsi:type="string"><![CDATA[<!-- Account links -->]]></argument>
                    </arguments>
                    </block>

Refrence file: vendor\magento\module-theme\view\frontend\layout\default.xml

Describe the elements of the Magento layout XML schema, including the major XML directives

How do you use layout XML directives in your customizations? How do you register a new layout file?

Ans:

There are 4 layout xml directives to strucure the page:

move elements
referenceContainer - change attributes, add children
referenceBlock - change template, position before/after, add arguments, add children, set no display
add HEAD scripts/styles

To register a new layout files follow the steps:

                                Place layout in one of directories:

                                custom-module/view/base/layout/
                                custom-module/view/frontend/layout/
                                custom-theme/Magento_Checkout/layout/
                                Or the same with page_layout directory.

                                When extending page layout, don't copy-paste layout="..." attribute if not intended.

                                Use standard XML namespaces:

                                <layout xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                                xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/layout_generic.xsd">
                                <page
                                xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                                xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd"
                                >

Create and add code and markup to a given page

How do you add new content to existing pages using layout XML?
Ans:
There are 2 type of pages in the Magento. CMS Page and Module page. CMS page is created from admin panel. But module pages are created in a module with help of controller and layout xml. First take example of CMS pages and see how to add code and markup. For this we take example of home page . Suppose we want to show bestseller products in home page using code. Needed components: template, block and home page's layout xml. First create/edit cms_inde_index.xml file inside app/design/frontend/<?theme_vendor>/>?theme_name>?/Magento_Theme/layout/ and below code:
```
                                <?xml version="1.0"?>
                                <page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                                xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
                                <body>
                                <referenceContainer name="content">
                                <block class="Vendor\Module\Block\Bestseller" name="bestseller" template="Magento_Theme::bestseller.phtml"></block> 
                                </referenceContainer>
                                </body>
                                </page>
                                        
```
Next, create block class and template as per path used in above xml handler of homepage. Put you custom logic inside the template and block. After preceding steps are done, it will add the bestseller products in homepage content.

Take Practice Test

Practice means do something many times. It enhances your skill and makes you perfect for exam environments. Practice tests help ease anxiety and bridge the gaps in course content. Let's say you studied all the topics, gone through video sessions. But what is needed now for this Adobe exam is practice on scenario-based questions. This means, in the viewpoint of development how much you understand the real-world software development workflows. So before taking the actual Adobe exam, we do suggest a practice test exam.

Here are the important points why one should take practice test:

Stimulates your test day routine and testing environment when taking practice tests.
Highlights where you need improvement, including time.
Fills the study gaps of trainig, study guide or online learning documents.
Reminds the cuttoff marks, questions frequncey as per topics.
Increases the chance of success.
Increase ability to solve scenerio based and practicle questions.

We reccomend taking at least one online practice test exams. You can purchase Adobe Certified Professional (AD0-E702) Questions exam for best preparation. It covers 3 separated practice sets, scenario based questions, and latest exam topics.

Be Confident

You should focus on how to gain confidence, rather than become confident. Confidence is the tool anyone can use to pre-determine exam success. You must consider this point at the beginning to make sure preparation helping to gain confidence. So I would say about planning before preparation. If you gone through previous tabs, you would have understood the preparation roadmap of AD0-E702 Adobe Certified Professional exam. Like you should start from Magento devdocs, go through basic tutorials one by one there, create a theme, create a module, understand admin-panel configurations, cover exam topics, and take a good test exam. These all basically build your confidence and drive in the success path.

So lets point out the facts you should consider to gain confidence before exam:

Prepare Well.
Good preparation is very important to upskill and gain the confidence in the exam. If you have just started your carrer, you should focus more on the practical questions means scenerio based questions. Apart from study session you should focus on the development flow as well.
Take note of your learning.
It's good habit to notedown the study sessions. It increases the memory capability and important [part of reading or hearing the study sessions
Be relax and think positive
A positive attitude keeps you on the right track of thinking. It becomes easier to concentrate on focus on the study/exam.
Do not discuss more just before exam
Discussion should be done only on right time. Means, before 1 week when you study something you should discuss at that time to make it more perisistant and memorable. So always choose the right time for discussion.
Taking it further
Apart from learnings you should also be aware of exam environments in advance. Know the timframe, quetsions, cuttoff on the topics etc before 1 week of exam time.

Hope, this learning help you to prepare in the right track and pass the certification exam. Thankyou for your time.
All the best, ExamTask.
