Comprehensive and Detailed Explanation From Exact Extract:

A CRM system facilitates collaboration among sales, marketing, and customer service teams by acting as a centralized platform where customer-related information is stored, updated, and shared. This centralized sharing platform allows all teams to:

Access the same up-to-date customer profiles, interaction history, and preferences

See previous communications, issues, and opportunities related to each customer

Coordinate activities (such as campaigns, sales follow-ups, and support cases) based on a unified view of the customer

Avoid duplicated efforts and conflicting messages

By providing this shared environment, CRM ensures that each team’s actions are informed by the same data, improving coordination and the overall customer experience.

Option A (Managing campaign workflow approvals) is a specific marketing process, not the broader cross-team collaboration capability.

Option B (Assigning shared customer tasks) can be a useful function, but it is one feature inside the broader concept of collaborating via a centralized platform.

Option C (Tracking internal communication metrics) focuses on measurement rather than enabling day-to-day collaboration around customer information.

Therefore, the way a CRM system most directly facilitates collaboration among sales, marketing, and customer service is by providing a centralized sharing platform for customer data and interactions.

An Extranet extends an organization’s internal network to provide controlled access to external users such as suppliers, vendors, and business partners. It uses security mechanisms like authentication and encryption to ensure that only authorized external parties can access the relevant internal resources.

Option A (Intranet): Internal-only network for employees; not accessible to outside users.

Option B (VPN): Provides secure remote connections for users but does not inherently grant controlled access to internal systems for external organizations.

Option C (LAN): A local network limited to internal devices in a small geographic area.

Thus, the correct type of network is an Extranet.

A primary key in a relational database table is used to uniquely identify each record in that table. It enforces entity integrity by ensuring that each row can be distinguished from every other row. A primary key must contain unique values and it cannot contain NULL values. This guarantees that every record is distinct and can be retrieved, updated, or related to other records efficiently.

The primary key serves as the central reference point when creating relationships between tables through the use of foreign keys, thus enabling referential integrity within the database. Without a primary key, it would not be possible to maintain consistent and reliable relationships across different tables.

Option A is incorrect because connecting tables to external systems is not the role of a primary key; this function is handled through integration tools or middleware.

Option B is incorrect because managing user access is controlled by database access control mechanisms, not primary keys.

Option D is incorrect because improving storage efficiency is related to data normalization, indexing, and storage optimization, not primary key assignment.

Therefore, the correct function of a primary key is to identify each record in a table uniquely, ensuring data integrity and reliable referencing across the database.
