What does a URL Rewrite do?

1. A. It updates the URL that is stored on the server.
2. B. It changes the way a URL appears in the browser
3. C. It updates the URL to a domain that is not being Indexed.

Correct Answer: B
A URL Rewrite in Magento changes the way a URL appears in the browser. This is particularly useful for improving the readability and SEO of a URL. For example, a URL rewrite can be used to transform a long and complex URL into a shorter and more user-friendly version. It's important to note that while a URL rewrite changes the URL's appearance in the browser, it doesn't change the actual location of the resource on the server. This distinction is crucial for understanding how Magento handles URL rewrites and redirects, facilitating a more intuitive navigation structure within the store without altering the underlying server resources.

An Adobe Commerce developer adds a new extension attribute to add an array of values to the invoices that are fetched through the APIs.
After a while, their technical manager reviews their work and notices something wrong with the extension_attributes. xml file that the developer created in their module:
What is the problem with this xml snippet?

1. A. The extension attribute references the wrong interface, it should have referenced the Magento\saies\Api\data\invoiceinterface.
2. B. The extension attribute references the repository instead of the interface it implements (Magento\saies\Api\invoiceRepositorymterface).
3. C. The type is wrong, string [] should be replaced with array.

Correct Answer: A
When adding extension attributes in Adobe Commerce, it's essential to reference the correct interface in the extension_attributes.xml file. Extension attributes in Magento are used to add custom data fields to existing entities, and these should extend the core entity interfaces, not their repositories.
In this case:
✑ The developer needs to reference Magento\Sales\Api\Data\InvoiceInterface, which represents the data structure of invoices, rather than any repository or incorrect
interfaces.
✑ The extension_attributes.xml should specify the data interface (e.g., Magento\Sales\Api\Data\InvoiceInterface) to ensure the extension attribute is correctly applied to the invoice entity and is accessible when fetching invoices through APIs.
Correct XML format:
<?xml version="1.0"?>

What is an advantage of the read-only core file system using Adobe Commerce Cloud?

1. A. Ensures that all changes to the production environment are tracked.
2. B. Improves website performance.
3. C. Reduces the number of attackable surfaces significantly

Correct Answer: A
The read-only core file system on Adobe Commerce Cloud ensures that all changes to the production environment are tracked. This is because any changes to the code must go through version control, and the deployment pipeline, which includes stages like build, staging, and production. This approach helps maintain consistency across environments, ensures deployment best practices, and reduces human error by preventing direct changes on production servers.

How are multiple EAV attributes belonging to the same entity grouped in the database?

1. A. Based on the sizes of values they contain
2. B. Based on all numeric values being stored in one table while text values are stored in the other
3. C. Based on the types of values they contain

Correct Answer: C
Multiple EAV attributes belonging to the same entity are grouped in the database based on their data types, such as datetime, decimal, int, text, or varchar. For example, all attributes with datetime values are stored in one table, while all attributes with text values are stored in another table.
The sizes or numeric/text values of attributes do not determine how they are grouped in the database.
Verified References: [Adobe Commerce Developer Guide - EAV data model]
Magento's EAV (Entity-Attribute-Value) model organizes attributes based on their data types to optimize storage and retrieval. Attributes are grouped into different tables based on whether they store values of types such as integer, varchar (text), decimal, datetime, etc. This organization allows Magento to efficiently manage the diverse data types associated with products, customers, and other entities, ensuring data integrity and optimizing database performance by using appropriate indexing and storage mechanisms for each data type.
