AD0-E718 Adobe Commerce Architect Master Questions and Answers

According to the Adobe Commerce Developer Guide2, a union type is a special kind of object that can be one of several types. It is useful for returning disjoint data types from a single field. In this case, the output of the mutation can be either Cart or ConfigurableProduct, depending on the number of variants of the given product. Therefore, a union type should be declared for the output of this mutation, as shown in option C. The other options are not valid syntax for union types.

C would involve creating a new custom condition for customer segments that allow for choosing if a user is part of a B2B company, and then use this segment to modify the output accordingly. E would involve creating a new HTTP Context variable to allow for separate public content to be cached for users in B2B companies, where the output can be modified accordingly.

To show the B2B account features in the header of the site on every page for the logged-in users who are part of a B2B company account, the Architect should recommend two solutions: C) Create a new custom condition for customer segments that allow for choosing whether a user is part of a B2B company and then use this segment to modify the output accordingly. This solution will allow the merchant to create a customer segment based on the custom condition and use it to display different content in the header for B2B users. E) Create a new HTTP Context variable to allow for separate public content to be cached for users in B2B companies where the output can be modified accordingly. This solution will ensure that the public content cache is varied based on the custom HTTP Context variable, which can be set based on whether the user is part of a B2B company or not. Option A is incorrect because switching the theme based on the user’s B2B status is not a scalable or maintainable solution, and it will also affect the entire site’s appearance, not just the header. Option B is incorrect because checking the user’s B2B status within a block class will not work with public content cache, as it will not vary the cache based on that condition. Option D is incorrect because setting the user’s B2B status in the customer session will not work with public content cache, as it will not vary the cache based on that data.

The ‘after’ plugin is not suitable for modifying the arguments or return value of the original method. The ‘around’ plugin allows the plugin method to wrap around the original method and modify its behavior and output.

By setting the same cookie domain for both websites, the customer base can be shared between both websites, as the customer will be authenticated by the same cookie across both sites. This will ensure that customers don't have to log in twice when switching between the two sites.

Setting Cookie Domain for both websites to “.example.com” will allow both websites to use the same customer base. This is because the cookie domain determines which websites can access the customer information stored in the cookie. By using a common domain, both websites can share the same customer cookie. See Multiple websites or stores in the Adobe Commerce Help Center1.
