A newly hired developer discovers that there are multiple triggers on the case object.
What should the developer consider when working with triggers?

A developer needs to display all of the available fields for an object.
In which two ways can the developer retrieve the available fields if the variable myObject represents the name of the object? (Choose two.)
Use myObject.sObjectType.getDescribe().fieldSet() to return a set of fields. Use mySObject.myObject.fields.getMap() to return a map of fields. Use Schema.describeSObjects(new String[]{myObject})[0].fields.getMap() to return a map of fields. Use getGlobalDescribe().get(myObject).getDescribe().fields.getMap() to return a map of fields.
Using the Schema Builder, a developer tries to change the API name of a field that is referenced in an Apex test class.
What is the end result? The API name is not changed and there are no other impacts. The API name of the field and the reference in the test class is changed. The API name of the field is changed, and a warning is issued to update the class. The API name of the field and the reference in the test class is updated.
A developer wants to override a button using Visualforce on an object.

A method is passed a list of generic sObjects as a parameter.
What should the developer do to determine which object type (Account, Lead, or Contact, for example) to cast each sObject?
Use the first three characters of the sObject ID to determine the sObject type. Use the getSObjectType method on each generic sObject to retrieve the sObject token. Use the getSObjectName method on the sObject class to get the sObject name. Use a try-catch construct to cast the sObject into one of the three sObject types.
A developer has the controller class below.
Public with sharing class myFooController {

Which two strategies should a developer use to avoid hitting governor limits when developing in a multi-tenant environment? (Choose two.) Use collections to store all fields from a related object and not just minimally required fields. Use methods from the “Limits” class to monitor governor limits. Use SOQL for loops to iterate data retrieved from queries that return a high number of rows. Use variables within Apex classes to store large amounts of data.
While writing a test class that covers an OpportunityLineItem trigger, a Developer is unable to create a standard PriceBook since one already exists in the org.

Use Test.loadData() and a Static Resource to load a standard Pricebook. Use @TestVisible to allow the test method to see the standard PriceBook.

On a Visualforce page with a custom controller, how should a developer retrieve a record by using an ID that is passed on the URL? Use the constructor method for the controller.

List<Case> childCases = new List<Case>();for (Case parent : Trigger.new){Case child = new Case (ParentId = parent.Id, Subject = parent.Subject);childCases.add(child);}insert childCases; What happens after the code block executes?

The trigger fails if the Subject field on the parent is blank.
