QUESTION 46
A merchant sells shoes with multiple variations such as a color and size. A shoe is represented by a configurable product. There are seven different colors and four sizes.
What is the minimal amount of simple products that represent a combination of color and size needs to be created in order to make a shoe salable?

Each color and size must have at least one representation, so a minimum of seven products is needed

One simple product that represents a combination of color and size is enough

A product may be purchased even without any combination available. The color and size may be adjusted during order fulfillment

A simple product for every combination must be created

QUESTION 47

Where do you define your module’s frontName?

etc/frontend/routes.xml

QUESTION 48
You got a notification about error that occurred on a production environment. The merchant gave you the error identifier.
How do you find the error message based on the identifier?

An error is written to the var/log/exception.log file including the identifier

The error is sent to the pre-configured error email with the identifier in the subject

QUESTION 49
In a code review of a merchant’s site you have discovered that there are multiple observers for the checkout_submit_all_after event. After closer inspection, you notice one of these observers is relying on the others being executed before it is called.
What risk does this pose, and how can it be mitigated?

There is no risk posed as long as each event observer specifies a correct sortOrder. Nothing needs to be changed.

Event observers are fired in alphabetical order of the observer name. There is no risk here.

Magento only supports one observer per event. These observers will need to be combined into a single point of customization.

Order of listener execution cannot be guaranteed, resulting in a fragile implementation. This code should be re-worked using plugins

QUESTION 50
During a code review of a module MyCompany_PaymentCurrencies you see a configuration field declared in the file etc/adminhtml/system.xml:

The input field will not be visible if a store view scope is selected in the system configuration

The input field will only be visible if a website’s default store scope is selected in the system configuration

The input field will be disabled if a store view scope is selected in the system configuration
