To allow for long-term self-sufficiency in segmentation, Northern Trail Outfitters should use data filters. Data filters are a user-friendly tool that allows marketers to segment their data based on criteria and conditions without coding. Data filters can also be refreshed and reused for different campaigns. Attribute groups are used to link data sources in Contact Builder, not for segmentation. Publication lists are used to manage opt-in preferences, not for segmentation. Query activities require SQL knowledge and coding skills, which the marketing team lacks.

# Comprehensive and Detailed Explanation: The Blockout Window in MobileConnect prevents SMS messages from being sent during specified hours, automatically holding messages for delivery until after the blockout period or discarding them based on configuration. It directly addresses the need to prevent delivery during nighttime hours.
# Why Other Options Are Incorrect:
* A and B: These are manual data management activities, not real-time or dynamic enough for Journey- based sends.
* C: Journey Goals relate to achieving a Journey outcome, not message send timing.

Comprehensive and Detailed Explanation:
The correct answers are B and D.
* B - The Mobile Number field must be Text type in MobileConnect and include country code (e.g., +1
555-555-5555).
* D - A Phone type field is necessary to validate and standardize mobile number formats inside MobileConnect.
Both fields are used for identifying recipients during MobileConnect sends.
# Why others are wrong:
* A and C: Locale fields are used for language/country preferences, not required for MobileConnect message sending.
