Two pings were issued from a host on a local network. The first ping was issued to the IP address of the default gateway of the host and it failed. The second ping was issued to the IP address of a host outside the local network and it was successful. What is a possible cause for the failed ping?
- The default gateway is not operational.
- The default gateway device is configured with the wrong IP address.
- The TCP/IP stack on the default gateway is not working properly.
- Security rules are applied to the default gateway device, preventing it from processing ping requests.
|Explanation & Hint:
The scenario you’ve described is somewhat unusual because typically, if a ping to the default gateway fails, pings to external hosts should also fail, as the default gateway is the local network’s access point to outside networks. However, given the situation, one plausible explanation for the failed ping to the default gateway but successful ping to an external host could be:
The other possibilities you mentioned are less likely given that a ping to an external host was successful:
Therefore, the most likely scenario given your description is that the default gateway has security rules in place that specifically block ping requests from the local network.
