Explanation
To import the data, segment the data, and execute the daily sends as soon as the file is generated by the data lake instance, Northern Trail Outfitters should use a triggered automation that contains an import activity, a series of query activities, and a series of sends. A triggered automation can start when a file is dropped in a specified location, such as an FTP folder. An import activity can import the file into a data extension. A series of query activities can segment the data based on the criteria for different campaigns. A series of sends can send the emails to the segmented data extensions. References:

Explanation
Creating an installed package in Marketing Cloud with Read and Write permissions for data extensions should be used to facilitate the functionality of upserting rows into a data extension using a REST API endpoint. An installed package is a container for one or more API integrations that provides authentication credentials and permissions for accessing Marketing Cloud resources. Read and Write permissions for data extensions allow the API integration to retrieve and modify data in data extensions. References:

Explanation
Three questions that are relevant to determining a solution for automating a process of importing data from a data warehouse into Marketing Cloud are:
Is the data file a delta or a historical file? This question will help determine how to handle existing records and avoid duplication or overwrite. A delta file contains only new or updated records, while a historical file contains all records regardless of changes.
Will the data file be placed on the SFTP at the same time daily? This question will help determine how to schedule an automation or trigger an event based on file drop. If the data file is placed on the SFTP at different times, then a File Drop Automation may be more suitable than a Scheduled Automation.
Does someone need to be notified if an error happens on import? This question will help determine how to handle errors and exceptions during import. If someone needs to be notified, then an email notification activity or a verification activity may be added to the automation.
Whether the data extension has a data relationship or not is not relevant to determining a solution for importing data, as it is only used for creating relationships between data extensions in Email Studio. Whether the file has more than 5,000 rows or not is not relevant to determining a solution for importing data, as it does not affect how data is imported or processed. References:

Explanation
Three considerations that should be made before implementing MobileConnect are:
Long and Short Codes are not available for all countries. Long codes are local phone numbers that can be used for sending SMS messages in some countries, while short codes are special numbers that can be used for sending SMS messages in other countries. However, not all countries have long codes or short codes available or supported by MobileConnect.
Inbound messaging only works with local Long or Short Codes. Inbound messaging is the ability to receive SMS messages from subscribers in response to outbound messages or keywords. This feature only works with local long codes or short codes that match the country of the subscriber's mobile number.
Not all countries are supported by MobileConnect. MobileConnect relies on mobile operators and aggregators to deliver SMS messages to different countries, but not all countries have these services available or supported by MobileConnect.
NTO would not be charged by mobile operators directly for messages, as they would pay for message credits or bundles through Marketing Cloud billing. Opting in for messages can be done via inbound message or other methods, such as web forms or APIs. References:

Explanation
To send out a biweekly newsletter with personalized property listings for new contacts added to a newsletter campaign in Salesforce CRM, a real estate agency should use Automation Studio to prepare personalization data and initiate journey. Automation Studio can run a scheduled automation that imports new contacts from Salesforce CRM into a data extension, runs query activities to join and filter property data based on contact criteria, and injects contacts into a journey that sends the newsletter with personalized content.
