Which of the following is NOT displayed on the Dashboard?

The Dashboard in a Secure Email Gateway (SEG) is designed to provide an overview of key metrics and information related to email security and mail flow. It typically includes information that helps administrators monitor the system's performance and identify potential issues.

The option indicating that user account details are not displayed on the Dashboard is correct because the Dashboard focuses on metrics that relate to email security rather than individual account information. This includes data such as recently rejected types of emails, which provides insights into threats that the system has blocked, mail flow volume for tracking the load on the system, and the condition of various services like Directory, Journal, and Exchange, which ensures that the email processing infrastructure is functioning properly.

User account details are more likely found in specific account management sections of an SEG rather than on the Dashboard, which is meant for higher-level monitoring and reporting. Thus, it makes sense that an administrative tool like the Dashboard would not include granular data such as user account details.
