You need to do an analysis of Admin actions on the website for a 24 hour period that happened 90 days ago using the Admin actions log. Assuming that the Log Entry Lifetime store configuration setting has not been changed from the default, where do you access the data?

• It is archived in the var\logging\archive folder on the server
• It is available by default for review in the actions log report grid
• It has been permanently deleted by the Magento log rotation cron
• It is archived in the magento_logging_event_archive table

A merchant is planning to create a single scheduled update for one million products. They are wondering about website performance. What two performance issues will the update cause?

• Magento will index all records in the cataiog_product_entity table regardless of the version so the index tables will be big
• When applying a scheduled update Magento will reindex all affected products
• The catalog_product_entity_* tables will contain all the staged values which slows down all queries related to them
• Magento runs a cron job every minute to generate and maintain preview data

Suppose there are 3 classes: Class A, B and C. Class C have dependecy of Class A You need to overrride/change an argument of class A, create an object of it and inject in Class B in such a way that it should not affect the class C. What should be the magento standard way to do this:In module’s etc/di.xml, define virtualType node to override argument and create a subclass of

• Then use type node to pass the subclass A object into class B.
• In module’s etc/config.xml, define virtualType node to override argument and create a subclass of
• Then use type node to pass the subclass A object into class B.
• In module’s etc/system.xml, define virtualType node to override argument and create a subclass of A. Then use type node to pass the subclass A object into class B.
• In module’s etc/menu.xml, define virtualType node to override argument and create a subclass of
• Then use type node to pass the subclass A object into class B.

When your class will be instantiated all the dependencies injected in your class constructor will also get instantiated, and it will trigger a chain reaction of object creation, this can really slow down the process. What could be the solution of above problem?

• Use Proxy classes with help of di.xml
• Use VitualType classes with help of di.xml
• Use Dependecy Injection with help of di.xml
• Use factory classes instead of Model.

You are debugging a problem with a shopping cart price rule which gives free shipping for the whole cart if the subtotal is greater than $100. You are seeing that when a custom shipping method is selected, the shipping price is still present even though the subtotal is greater than $100.How do you fix this problem?

• Create an option allow_freeshiping in the system configuration of the shipping method and set its value to 1
• Add the shipping method's code to the price rule action
• Modify the carrier class to process the free_shipping flag of the quote items
• Add the shipping method's code to the price rule condition

A client uses an external PIM for managing product information. They want to run a cron job everyminute to update and create products. The site is using the "Update by schedule" index mode and the full page cache is enabled.What is required to make these updates visible on the frontend?

• The indexer_update_all_views cron will reindex the products and clean only the necessary entries from cache
• The indxer_update_all_views cron will reindex the products, however the full page cache will need to be manually flushed
• The indexer_update_all_views cron will reindex the products and clean the entire full page cache
• The cron job will also need to run a reindex and flush full page cache on each run for updates to be reflected on the front end of the website

You are developing an in-house solution for catalog management which is implemented as a Magento module called MyCompany_MyModule. To streamline integration with the ERP system you decided to expose MyCompany_MyModule'S functionality via REST.What are the three minimum requirements to achieve this?

• Add webapi. xml declarations for all methods to be exposed
• Specify the parameter and return types in the PHP method signatures
• Represent all functionalities which need to be exposed as service contracts
• Specify the parameter and return types in the method annotations
• Add Cap: annotations to all methods which need to be exposed

You are integrating an external system from which products and categories will be synchronized with Magento.To keep the category tree synchronized, an identifier attribute needs to be added to the catalog_category entity. The identifier value is generated by the external system as an unsigned 3 byte integer and is global in scope. Your code will run many concurrent queries to select categories based on this ID in order to synchronize changes.Keeping performance in mind, what attribute backend type do you choose when creating the EAV attribute?

• int
• varchar
• static
• text

Suppose you are working with order collection where you need to get the Customer collection object in foreach loop to check wheather current order's customer accout is locked or not. For this you injected Magento\Customer\Model\Customer $customer in the constructor to use $customer collection object. But in loop when this object is used, you notice that it's returning the same customer even if you pass different customer id to filter the customer collection inside loop. What is the solution for this problem?

• Use proxy class for customer and use create() method to get a fresh customer object
• Use factory class for customer and use create() method to get a fresh customer object
• We can not filter a collection in foreach loop, need to use load() on customer model
• None of these

Suppose in a store there are 500 categories and it's increasing as per the need. Let's say your frontend developer asked you to modify the header and include CSS files on some specific categorypages based on the custom category attribute selection from backend. What should be the acceptable and easiest way to do this, so that no new file creation and code update will be required after implementation:

• create a new layout XML file for the category called catalog_category_view.xml and add the layout modification code
• create a new layout XML file for the category called catalog_category_view_selectable__CustomLayout.xmland assign it to the needed categories from backend, and add the layout modification code in it.
• create a custom layout handle for the category using observer layout_load_before and add the layout modification code
• create a custom layout handle for the category using observer layout_load_after and add the layout modification code
