Salesforce Marketing-Cloud-Developer Exam With Confidence Using Practice Dumps

To avoid data loss and ensure reliable data transfer to Marketing Cloud data extensions, follow these best practices:

• Handle 'Not Authorized' Errors: If a 'Not Authorized' error occurs, it is likely due to an expired or invalid access token. Request a new access token and retry the API call.
• Retry on Server Errors: If a server error occurs, it might be a temporary issue. Ensure the server is available and retry the call.
• Token Expiry Management: Store the expiry time of the access token and request a new one before the old token expires to prevent authorization issues.

A Query Activity in an Automation can fail for several reasons, including:

• The query takes more than 60 minutes to run (A)- Long-running queries are subject to timeouts, which can cause the query to fail.
• The query results in duplicate rows not allowed by the primary key (C)- If the query attempts to insert duplicate rows into a data extension that has a primary key constraint, it will fail.
• The query is inserting a value that is larger than the size of a field (E)- If the query attempts to insert data that exceeds the field size limits, it will result in an error.

When logging unsubscribe events from a CloudPage using the LogUnsubEvent Execute Call, it's crucial to capture and provide both the SubscriberKey and the JobID. The SubscriberKey uniquely identifies the subscriber, while the JobID identifies the specific email job from which the subscriber is unsubscribing.

• SubscriberKey: Identifies the subscriber in the Marketing Cloud.
• JobID: Identifies the email job that triggered the unsubscribe event.
