Explanation
A managed package is a type of app that can be installed from the AppExchange. Managed packages are typically created by ISV partners or developers who want to distribute and sell applications that are upgradeable and have intellectual property protection. Before installing a managed package, an administrator should consider the following:
A) Custom objects and custom fields used by the app count against the org's limits.
Managed packages may include custom objects and custom fields that are used by the app. These custom objects and custom fields count against the org's limits and may affect the performance or functionality of the org. Administrators should review the components and requirements of the app before installing it and make sure they have enough space and resources for the app. References:

Managed packages may require certain Salesforce editions or features to be enabled in order to work properly.
For example, some apps may require Lightning Experience, API access, custom permissions, or specific user licenses. Administrators should check the app's description and documentation before installing it and make sure they meet the prerequisites for the app. References:

Managed packages may require external, third-party web services to function properly. For example, some apps may integrate with other platforms or systems such as Google Maps, PayPal, or Twilio. Administrators should check the app's description and documentation before installing it and make sure they understand the implications and costs of using external web services. References:

Explanation
IP ranges are settings that restrict login access to Salesforce from specific IP addresses. Administrators can set IP ranges at the org level or at the profile level. If a user tries to log in from an IP address that is outside the allowed range for their profile or their org, they will not be able to access Salesforce. Therefore, if a user started to work remotely and is having an issue logging in, it could be because they are not in the IP range for their profile or their org. References:

Explanation
A primary account relationship is a feature that allows you to link a contact to a single account as its primary account. A primary account relationship is required on a contact regardless of the page layout settings or the contact to multiple accounts feature. This means that you cannot remove the primary account from a contact, but you can change it to another account. You can also add secondary accounts to a contact if you have enabled the contact to multiple accounts feature. References:

Explanation
An after-save autolaunched flow is a type of flow that runs in the background when a record is saved and performs actions based on the record data or changes. An after-save autolaunched flow does not require user input or interaction and can be triggered by a record-triggered flow element or by an Apex trigger. In this case, you can create an after-save autolaunched flow that runs when a Project record is created and creates a standard set of related Project Milestone records based on predefined values or variables.

Explanation
Data Import Wizard is a tool that allows administrators to import data for standard and custom objects in Salesforce using CSV files. Data Import Wizard can handle up to 50,000 records at a time and supports simple data transformations and validations. Data Import Wizard can be used to upload records for a custom object when the number of records is small and the import frequency is low.
