ServiceNow Certified System Administration Practice

The Knowledge Base in ServiceNow is primarily populated through the creation of articles that are organized into topics and categories. This structure allows users to easily navigate and find relevant information. Topics represent broad areas of knowledge, while categories are sub-sections that define specific subjects within those topics. Articles are the primary content pieces that provide detailed information, solutions, or instructions related to the defined categories.

While the other options include terms related to the management or categorization of information, they do not accurately describe the direct methods for populating the Knowledge Base. For example, labels and tags are often used for additional organization and searchability of articles but are not initial means of populating the knowledge base. Users, roles, and permissions pertain to access controls and do not contribute to the actual content of the Knowledge Base. Lastly, services, assets, and incidents might be relevant within a broader IT service management context, but they do not specifically relate to the Knowledge Base construction in terms of articles and categorization. Thus, the focus on topics, categories, and articles reflects the correct and relevant ways the Knowledge Base can be populated.
