Question 56

An Adobe Commerce developer has just finished creating a new custom entity, a block that extends
\Mangento\Framework\View|Element\abstractBlock that lists all of the existing entities and a controller with the appropriate handle to display the block.
The developer now wants to implement cache on the block so that when one of the custom entities is saved, the cache of the block is automatically invalidated.
According to best practices- what are the two steps to accomplish this? (Choose two.)

A.1. Override AbstractBlock: :getCecheKeyInfo and return an array containing the ids of all displayed entities.
2. Override AbstractBlock: :getCacheTags and return an array containing, for all displayed entities, the value returned by the getcachetag method of the model

B.1. Create an around plugin on the save( ) method of the model of the entity.
2. Use the cleanCacheByTags( ) method Of \MagentoVFramework\App\Cache\FlushCaehebyTae with a single argument containing the concatenation of a chosen key and the td of the entity.

C.1. Implement \Magento\framework\DataObject\identityInterface on the block that lists the entities.
2. Implement the getidentitiesO method on the block to return an array containing, for all displayed entities, the value returned by the getidentities() method ofthe model.
D)
1. Implement \magento\Frame\DataObject\identityInterface on the model of the entity.
2. Implement the getidentities() method to return the concatenation of a chosen key and the id of the entity.

Question 57

Which two techniques can be used to protecta storefront POST action againstCross Site Request Forgery (CSRF) attacks? (Choose two.)

A.The action needs to implement \Mgento\Framework\App\CSrfAwareActioninterface and include the validateForCsrf method implementing the actual protection logic.

B.The form sending data to that action needs to include a fornjtey parameter with a valid form key and the action must instantiate \Manento\Framwork\Data\ForumKey\Formkey\Validator validate it.

C.The form sending data to that action needs to include a form_key parameter with a valid form key which will automatically be used in a built-in CSRF validation.

D.The action needs to implement \Magento\Framework\App\ActionvHttpPosTActioninterface to trigger built-in CSRF validation.
