Adobe AD0-E717 Adobe Commerce Developer Professional Exam Practice Test

Answer : B

The access.log file stores the information about the requests and responses that occur on the web server, such as the IP address, timestamp, request URI, response code, and referer URL1.By checking the access.log file, a developer can identify the requests that resulted in 503 errors and the possible causes of those errors, such as traffic spikes, insufficient server resources, or misconfiguration1.

To check the access.log file on an Adobe Commerce Cloud project, a developer can use the following command in the CLI:

grep -r '\' 50 [0-9]' /path/to/access.log

This command will search for any lines in the access.log file that contain a response code starting with 50, which indicates a server error1.The developer can then compare the timestamps of those lines with the exception.log and error.log files to find more details about the errors1.

Alternatively, if the error has occurred in the past and the access.log file has been rotated (compressed and archived), the developer can use the following command in the CLI (Pro architecture only):

zgrep '\' 50 [0-9]' /path/to/access.log.<rotation ID>.gz

This command will search for any lines in the compressed access.log file that contain a response code starting with 501. The rotation ID is a number that indicates how many times the log file has been rotated.For example, access.log.1.gz is the most recent rotated log file, and access.log.10.gz is the oldest rotated log file1.

Answer : B

The customer data JS library is used to store private customer data in local storage. This data can be used to improve the customer's experience on the store, such as by remembering their shipping address or their preferred payment method.

The customer data JS library in Adobe Commerce is used for managing customer data on the client side, such as the shopping cart, comparison list, and wishlist. It does not store sensitive information like credit card details or usernames and passwords. Instead, it utilizes local storage to keep a private data section where customer-specific data is stored securely and accessed via JavaScript, making option B correct.

Answer : A

The correct way to inject a CMS block into a layout in Adobe Commerce is by using the <block> element with the class Magento\Cms\Block\Block and specifying the block identifier through an element with the name 'block_id'. This is shown in option A. The <block> tag defines the block class and name, and the tag contains child tags for each argument, where the 'block_id' argument specifies the identifier of the CMS block to be injected.

Answer : B

The view/{area}/web/css/source/main.less file is the default less file that is included by default. This file contains the main styles for the module.

In a custom module in Adobe Commerce, the default location for including custom LESS styles is typically view/{area}/web/css/source/_module.less. However, the most commonly used file for adding global styles is view/{area}/web/css/source/_extend.less. The view/{area}/web/css/style.less file is not standard, and the main.less file is used as an entry point for compilation but typically does not contain custom styles directly.

Answer : A

The web directory contains the static files that can be loaded directly. This directory includes files such as CSS, JavaScript, and images.

In Adobe Commerce themes, the web directory is used to store static files such as CSS, JavaScript, images, and fonts. These files can be loaded directly by the browser. The preprocessed and assets directories do not exist as standard directories in the theme structure for containing directly loadable static files.

Answer : B

The data-mage-init HTML attribute is used to initialize the jQuery UI widget for a specific HTML tag. This attribute specifies the name of the widget and its configuration options as a JSON object.

The x-magento-init HTML attribute is used to initialize RequireJS modules for a specific HTML tag. The data-ui HTML attribute does not exist in Adobe Commerce.

Verified Reference: [Adobe Commerce Developer Guide - Initialize JavaScript components using the data-mage-init attribute]

To initialize the jQuery UI widget in Adobe Commerce, the data-mage-init attribute is used in the HTML tag. This attribute allows specifying the widget's component and its configuration in a JSON format. The x-magento-init is used for initializing JavaScript components in a similar manner but is typically used within <script> tags. There's no standard data-ui attribute used for this purpose in Magento 2.

Answer : B, C

To initialize a theme in Adobe Commerce, at least two files are required: registration.php and theme.xml. The registration.php file is used to register the theme within the system, and theme.xml defines the theme's name, parent (if any), and other metadata. The theme.less file is not required for theme initialization but may be used for custom styling. The correct option for theme.xml is represented as 'theme.xml' (D), not 'themexml' as mentioned in the options.
