What is the result of enabling ICMP on the SMA?

Enabling ICMP on the SonicWall Secure Mobile Access (SMA) allows the device to respond to ping requests, which are useful for basic network diagnostics. The correct answer illustrates that enabling ICMP permits the SMA to answer pings specifically from another computer on the same subnet. This capability is important for local network troubleshooting, as it allows administrators to verify connectivity and diagnose potential network issues effectively.

The other choices do not accurately describe the functionality enabled by ICMP on the SMA. For instance, the option suggesting that it allows for replies to broadcast pings misrepresents the nature of ICMP replies, as broadcast pings are not typical for device responses in most configurations. The choice claiming that it disables all ping responses outright contradicts the purpose of enabling ICMP, which is to facilitate those responses. Finally, the option indicating that all network devices can ping the SMA does not specify the constraints that are typically found in network environments, such as subnet considerations and security settings that might restrict ping responses to particular devices or ranges. Thus, understanding the specific behavior of ICMP enabled on the SMA clarifies why it only allows responses to pings from devices within the same subnet.
