質問 # 63
A developer has a requirement to query three fields (Id, Name, Type) from an Account; and first and last names for all Contacts associated with the Account.
Which option is the preferred, optimized method to achieve this for the Account named 'Ozone Electronics'?
A)
B)
C)
D)
正解：B
質問 # 64
A company has a custom object, Order__c, that has a custom picklist field, Status__c, with values of `"New', `"In Progress', or `"Fulfilled' and a lookup field, Contact__c, to Contact.
Which SOQL query will return a unique list of all the Contact records that have no `"Fulfilled' Orders?
正解：B
解説：
The correct SOQL query to return a unique list of Contact records that have no 'Fulfilled' Orders is one that selects Ids from the Contact object where the Contact Id is not in the set of Contact Ids related to 'Fulfilled' Orders. This is done by a subquery that selects the Contact__c field from the Order__c records where the Status__c is 'Fulfilled'.
質問 # 65
An org has a requirement that addresses on Contacts and Accounts should be normalized to a company standard by Apex code any time that they are saved.
What is the optimal way to implement this?
正解：C
解説：
Apex triggers on Contact and Account with a helper class is the best practice for code reuse and maintaining clean trigger logic.
質問 # 66
A developer is writing a Visualforce page that queries accounts in the system and presents a data table with the results. The users want to be able to filter the results based on up to five fields. However, the users want to pick the five fields to use as filter fields when they run the page.
Which Apex code feature is required to facilitate this solution?
正解：A
解説：
The requirement described in the question calls for a flexible way to query records based on user-selected fields. Dynamic SOQL is the perfect tool for this job as it allows the construction of a SOQL string at runtime, which can include any number of fields and filter conditions that are determined at the time the user interacts with the page. This enables the creation of a highly customizable query interface. A, B, and C are not suitable for this requirement as they serve different purposes: A (Streaming API) is for receiving real-time streams of data changes, B (Metadata API) is for managing the metadata of your Salesforce org, and C (variable binding) is used in Visualforce to bind data between the page and the controller but does not provide dynamic query capabilities.

質問 # 67
After a platform event is defined in a Salesforce org,events can be published via which mechanism?
正解：C
解説：
Platform events in Salesforce can be published using a variety of mechanisms, including from external applications through the Salesforce APIs.
Option A is correct because external applications can use Salesforce APIs such as the REST API or the SOAP API to publish events to a platform event in Salesforce.
Options B, C, and D describe mechanisms that are not used for publishing platform events. Entitlement processes are for setting up and tracking service contracts, the standard Streaming API is for subscribing to events not publishing them, and outbound messages are a workflow action used to send information to external services, not for publishing platform events.
