Question

A FortiGate is configured to receive push updates from the FortiGuard Distribution Network, however, updates are not being received. Which are two reasons for this problem? (Choose two.)

Options

  • AThe FortiGate is connected to multiple ISPs.
  • BThere is a NAT device between the FortiGate and the FortiGuard Distribution Network.
  • CThe FortiGate is in Transparent mode.
  • DThe external facing interface of the FortiGate is configured to get the IP address from a DHCP

Explanation

The question asks for two reasons why a FortiGate configured for FortiGuard push updates might not receive them.

Common mistakes.

  • A. Being connected to multiple ISPs (e.g., in a redundant setup) does not inherently prevent FortiGuard push updates, provided the routing is configured correctly to reach the FDN and the IPsec tunnel can establish over an active path.
  • C. A FortiGate operating in Transparent mode can still receive FortiGuard updates, as its management functions, including FortiGuard communication, are handled by its management IP address and relevant routing.
