I want to say that i found the CRT-450 practice dumps not only accurate, i found that 100% accurate. I passed with flying colours.
No.# B correct answer
No.# @vero lara Oh I see it's 2 because only before update trigger increments count field, not before insert in this case. My bad!!
No.# I think is D.2. Because is a before update, not before insert. First, the workflow rule is executed, then the trigger because it was updated.
No.# @SF, @Pramod Jana if C is true then how can a class extend more than one base class?
No.# @test I think correct answers are definitely B and perhaps A. C is not correct because partial DML only helps in handling errors without rolling back the entire transaction, it doesn't directly address transaction control or governor limit avoidance.
No.# I think the answer should be B.3 because the workflow rule makes the before update trigger run once again. First the trigger increments count to 1, the the workflow rule is executed and the before update is triggered again, so count is doubly incremented to 3
I really needed some dumps like CRT-450 exam dumps to help me. I will recommend it to everyone. Good work freecram.
No.# Correct Answer:
B. An invocable method
Explanation:
Invocable Method: An invocable method is an Apex method that is annotated with @InvocableMethod and can be called directly from a Flow. It is designed to make Apex code accessible within declarative tools like Flow Builder. By using an invocable method, you can call out to the external system in real time, retrieve the necessary order details, and then display them in the Flow screen.
Why the Other Options Are Less Suitable:
A. An outbound message
Incorrect: An outbound message is used to send data from Salesforce to an external system and is generally used in workflows, not for retrieving data from external systems in real time.
C. An Apex REST class
Incorrect: An Apex REST class is used to expose Apex methods as RESTful web services, which would allow external systems to call Salesforce. However, in this scenario, you need to retrieve data from an external system, not expose Salesforce data.
D. An Apex Controller
Incorrect: An Apex Controller is used in Visualforce pages or Aura components and is not used directly in Flows. The scenario specifically requires a solution that works with Flow, making an invocable method the best choice....

No.# A is correct
A. Cascading delete operations
Correct: When a record is deleted and there are child records associated with it, the cascading delete will trigger delete triggers on the child records. This is a typical scenario that causes triggers to fire.
B. Updates to Feed Items
Incorrect: Feed items, such as Chatter posts and comments, do not cause standard triggers to fire on the related object. While they can trigger other actions (like processes or flows), they do not invoke triggers directly on the associated records.
No.# A & C are correct
A. To delete 15,000 inactive Accounts In a single transaction after a deployment
C. To run a batch Apex class to update all Contacts
No.# @MahmutS how would you access child records from a Formula field on the parent record? Not possible!
No.# The C is correct !
Because Standard controller is for a single record and Standard list controller is for more record (list of record)
with the help of your CRT-450 study materials, I passed my CRT-450 exam so smoothly. Thank you for so amazing masterpiece!
No.# D. The record will not be created and no error will be reported.
Explanation:
• Account a = new Account ();: This line creates a new instance of the Account object. However, no mandatory fields are set (such as Name), so this object is incomplete.
• Database.insert (a, false);: This line attempts to insert the new Account record into the database. The second parameter, false, means that the operation will allow partial success. If any error occurs, it will not throw an exception, but it will report the failure in the Database.SaveResult object.
Since no required fields are set for the Account object, the insertion will fail. However, because the allOrNone parameter is set to false, no exception will be thrown. Instead, the operation will fail silently, and the failure will be logged in the Database.SaveResult object, which is not captured in this code snippet.
No.# A
• <aura:application>: This tag is used to define an Aura application. When using a Lightning component within a Visualforce page, the Lightning component is typically wrapped in an Aura application.
• access="GLOBAL": This attribute makes the application globally accessible.
• extends="ltng:outApp": This attribute extends the ltng:outApp component, which is used to enable Lightning components to be used in Visualforce pages.
• <aura:dependency resource="c:accountList"/>: This tag declares a dependency on the c:accountList component, ensuring it is included and available.
No.# B. The parent component can invoke a method in the child component. This is possible by using @api decorator on the method in the child component, allowing the parent component to call this method directly.
D. The parent component can use a public property to pass the data to the child component. Public properties, decorated with @api, allow parent components to pass data to child components directly.
No.# C.
Explanation:
• The @AuraEnabled annotation is used to expose Apex methods to be callable from Lightning components. The cacheable=true attribute is used to cache the results on the client side to improve performance.
• The method should be public static to be accessible as a static method from the Lightning component.
• The return type should be List<Opportunity> to match the searchResults property that stores a list of Opportunity objects.
No.# C.
Explanation:
• In a custom SOAP Web Service in Salesforce, the class must be declared as global so that it can be accessed externally.
• The method that will be exposed as a web service method should be declared with the webservice keyword and it should be static.
• Helper methods that are not exposed to the web service can be declared as private.
