Which ports are used for FortiGuard Live Queries?

The correct choice for the ports used for FortiGuard Live Queries involves understanding the function and communication methods of these services. FortiGuard Live Queries are designed to collect and report real-time data to and from FortiGuard services, which predominantly rely on DNS lookups and secure data transmission.

The appropriate ports utilized in this process are UDP ports 53, which is the standard port for Domain Name System (DNS) queries. DNS is fundamental for looking up domain names and resolving them into IP addresses, which is vital for FortiGuard services as it identifies and verifies updates and queries to the services. The second port, 8888, is often assigned for various applications or services that could involve specific query protocols. In the context of FortiGuard Live Queries, it represents an additional communication path for secure queries outside traditional ports, suggesting a need for flexibility in how queries are sent and received.

While other ports listed in the choices appear to be used for other purposes (such as HTTP, HTTPS, or SSH), they do not specifically pertain to the Live Queries function, where rapid and efficient data retrieval is critical. Thus, UDP ports 53 and 8888 are correctly identified as the operational channels for FortiGuard Live Queries, allowing optimal
