Explanation
The correct answer is C because indicators are artifact values that can appear in multiple containers.
Indicators are a special type of artifacts that are used to store information that is relevant for threat intelligence, such as IP addresses, URLs, file hashes, etc. Indicators can be created using the add indicator action in any playbook block and can be collected using the get indicators action in the filter block. Indicators can also be used to trigger active playbooks based on their label or type. See Splunk SOAR Documentation for more details.

In Splunk SOAR, an event is a security occurrence that may require a response. It is ingested from a third- party source and can be labeled to group related events together. The default label for containers is "Events," which signifies potential threats13. A case, on the other hand, is a container that holds several containers, consolidating multiple events into one logical management unit. Cases can include artifacts and external evidence such as screen captures, analyst notes, and event data from third-party products22. They are used to manage and analyze investigation data tied to specific security events and incidents, providing a structured approach to incident response34.

Explanation
The correct answer is C because the global block can be used to import packages that will be used within the playbook. This can be useful for importing external libraries or custom modules that provide additional functionality or logic for the playbook. The answer A is incorrect because the global block cannot be used to execute code at the beginning of each run of the playbook, as the global block is only executed once when the playbook is loaded. The answer B is incorrect because the global block cannot be used to declare outputs that will be selectable within playbook blocks, as the outputs are declared in the individual blocks that produce them. The answer D is incorrect because the global block cannot be used to execute custom code after each run of the playbook, as the global block is only executed once when the playbook is loaded.

Explanation
The correct answer is B because the steps required to complete a full backup of a Splunk Phantom deployment are to first run the --backup --backup-type full command and then run the --setup command.
The --backup command creates a backup file in the /opt/phantom/backup directory. The --backup-type full option specifies that the backup file includes all the data and configuration files of the Phantom server.
The --setup command creates a configuration file that contains the encryption key and other information needed to restore the backup file. See Splunk SOAR Certified Automation Developer Track for more details.

In Splunk SOAR, playbooks can execute actions either synchronously (waiting for one action to complete before starting the next) or asynchronously (allowing actions to run concurrently). If a playbook starts executing before the previous one has completed, it indicates that synchronous execution has not been properly configured between these playbooks. This is crucial when the output of one playbook is a dependency for the subsequent playbook. Options B, C, and D do not directly address the observed behavior of concurrent playbook execution, making option A the most accurate explanation for why the second playbook starts before the completion of the first.
synchronous execution is a feature of the SOAR automation engine that allows you to control the order of execution of playbook blocks. Synchronous execution ensures that a playbook block waits for the completion of the previous block before starting its execution. Synchronous execution can be enabled or disabled for each playbook block in the playbook editor, by toggling the Synchronous Execution switch in the block settings. Therefore, option A is the correct answer, as it states the cause of the behavior where the second playbook starts executing before the first one completes. Option B is incorrect, because the first playbook performing poorly is not the cause of the behavior, but rather a possible consequence of the behavior. Option C is incorrect, because the sleep option for the second playbook is not the cause of the behavior, but rather a workaround that can be used to delay the execution of the second playbook. Option D is incorrect, because the join configuration on the second playbook is not the cause of the behavior, but rather a way of merging multiple paths of execution into one.
