                                  Salesforce Platform Developer II Sample Questions (Q129-Q134):

                                  NEW QUESTION # 129
                                  A developer is writing code that requires making callouts to an external web service. Which scenario necessitates that the callout be made in an asynchronous method?

                                  Answer: D

                                  Explanation:
                                  In Salesforce, a critical restriction is that synchronous callouts cannot be made from within an Apex trigger.
                                  This architectural limitation is in place because triggers execute as part of a database transaction. Allowing a synchronous callout-which waits for a response from an external system-would keep the database connection and transaction locks open for an indeterminate amount of time. This could lead to severe performance bottlenecks and row-locking issues across the entire organization. Therefore, if a developer needs to initiate an external integration based on a record change (trigger), the logic must be handed off to an asynchronous process, such as a @future(callout=true) method, a Queueable class, or a Platform Event.
                                  Regarding the other options: A callout that takes longer than the maximum timeout (120 seconds) will fail regardless of whether it is synchronous or asynchronous, though async is often preferred for longer-running tasks to avoid blocking the user UI. Salesforce allows up to 100 callouts in a single transaction, so making more than 10 (Option C) does not inherently force an asynchronous approach unless the 100-callout limit is exceeded. Finally, the use of the REST API (Option D) is simply a protocol choice and does not dictate the execution context. Consequently, the presence of an Apex trigger is the only scenario listed that programmatically mandates the use of asynchronous execution to perform a callout.


                                  NEW QUESTION # 130
                                  Universal Containers is using a custom Salesforce application to manage customer support cases. The support team needs to collaborate with external partners to resolve certain cases. However, they want to control the visibility and access to the cases shared with the external partners. Which Salesforce feature can help achieve this requirement?

                                  Answer: A

                                  Explanation:
                                  Apex managed sharing is the correct feature to control the visibility and access to cases shared with external partners. It allows developers to programmatically create sharing records that grant access to users based on specific criteria, providing granular control over record sharing.

                                  NEW QUESTION # 131
                                  A developer notices the execution of all the test methods in a class takes a long time to run, due to the initial setup of ail the test data that is needed to perform the tests.
                                  What should the developer do to speed up test execution''

                                  Answer: A


                                  NEW QUESTION # 132
                                  Business rules require a Contact ta always be created when a new Account is created.
                                  What can be used when developing a custom screen to ensure an Account is not created if the creation of the Contact fails?

                                  Answer: C


                                  NEW QUESTION # 133
                                  A developer needs to implement a historical Task reporting feature that allows users, assigned to a custom profile named "Auditors", to perform searches against the Tasks related to the Account object.
                                  The developer must ensure the search is able to return Tasks that are between 12 and 24 months old. It should exclude any tasks which have been deleted, and include Tasks whether archived or not.
                                  Given the following code, which select statement should be inserted at the placeholder as a valid way to retrieve the Tasks ranging from L2 to 24 months old?

                                  Answer: A

                                  Explanation:
                                  To retrieve Tasks that are between 12 and 24 months old, we need to use a SOQL query that filters based on the CreatedDate. The query must exclude deleted records and include both active and archived tasks. Since Tasks can be archived after a certain period (typically 12 months), we must ensure the query includes these as well.
                                  * Option C is correct because it uses ALL ROWS in the SOQL query, which includes both active and archived (soft-deleted) records. The query also correctly uses a range for CreatedDate to ensure it selects Tasks created between 12 to 24 months ago.
                                  * Option A is incorrect because it does not include the ALL ROWS keyword, which is necessary to include archived Tasks in the results.
                                  * Option B is incorrect because it only retrieves Tasks created in the last 12 months, not between 12 to 24 months ago.
                                  * Option D is incorrect because it does not filter Tasks based on their creation date correctly to include only those that are between 12 and 24 months old.
