SPI firewalls can handle both ICMP and UDP.

Explanation:
Stateful inspection tracks the state of active conversations and uses that context to decide which packets to allow. Because of this, it can manage traffic for protocols that don’t establish a traditional connection, like ICMP, as well as protocols that run over UDP. For ICMP, the firewall records the request and its matching reply, ensuring the response belongs to a tracked interaction. For UDP, it creates a temporary state entry when an outbound UDP datagram is sent, and incoming replies are allowed only if they match that outbound transaction within a timeout. This ability to maintain state across packets lets SPI handle both ICMP and UDP, so the statement is true.
