A developer would like to relate an external data object (Social Media Posts) to the contacts
object in Salesforce to track every post the contact has made in the external platform. How can
the developer achieve this?Choose 1 answer.

A. Create a lookup relationship and update the record ID through integration
B. Create an indirect lookup relationship using a custom field with External ID and Unique
attributes
C. Create an external lookup relationship using a custom field with External ID and Unique
attributes
D. Create a master-detail relationship and update the record ID through integration - ANS
B

An indirect lookup relationship links a child external object to a parent standard or custom
object. When you create an indirect lookup relationship field on an external object, you specify
the parent object field and the child object field to match and associate records in the
relationship. Specifically, you select a custom unique, external ID field on the parent object to
match against the child's indirect lookup relationship field, whose values come from an external
data source.

An external lookup relationship generally relates a Salesforce child record to an external parent
record.Lookup relationships and master-detail relationships do not relate to external records.

The Stage field on all related Opportunity records should be updated to 'Closed Lost' when the
value of the 'Status' field on an account record is changed to 'Inactive' by a sales user. What
could be used to meet this requirement?Choose 1 answer.

A. Workflow rule
B. Process Builder
C. Approval Process
D. Flow - ANS B

, Process Builder is capable of updating related records through the Update Records action type.

Although a flow is also capable of updating related records, the recommendation is to always go
with the solution that is easier to implement, which in this case is Process Builder. Workflow
rules cannot operate on child records of an object. Cross-object field updates are available for
an object's parent record only under certain conditions. An approval process cannot be used to
update child records.

The code snippet below throws an error during bulk data load. What is the root cause?Choose 1
answer.

for (Contact con : Trigger.new) {
if (con.PostalCode__c != null) {
List<State__c> states = [SELECT StateId__c, PostalCode__c From State__c WHERE
PostalCode__c = :con.PostalCode__c];
if (states.size() > 0) { con.StateId__c =states[0].StateId__c;
}
}
}

A. SOQL query is located inside the for loop code
B. No update DML over list of Contacts
C. Variable 'con' is not declared
D. Condition is invalid and will always be null - ANS A

There is a governor limit that enforces a maximum number of SOQL queries allowed in a single
transaction. To help avoid hitting the limit, queries inside for loops should be avoided. If a query
is needed, query once, retrieve all the necessary data in a single query, and then iterate over
the results. A SOQL for loop can also be used to automatically retrieve and return results in
batches of 200 records.

The variable 'con' is declared in the for-loop definition. The null check on the PostalCode field is
a valid condition. Absence of a DML operation does not throw an error. However, note that for
before triggers, a DML statement on the object that invoked the trigger will throw an
SObjectException. Also, a DML statement inside the for loop would potentially cause a DML
limit exception.

How can SOQL injection be prevented?Choose 1 answer.

A. Use the preventQuotes method
