Connectivity Problem with Ethernet-Connected Sensor: Reasons and Solutions

Reasons for Connectivity Problem with Ethernet-Connected Sensor

Question

A network is being configured for an Ethernet-connected sensor.

The sensor fails to send data to the configured destination.

The IP address of the sensor can be pinged from a laptop on the same subnet.

When a different subnet is used, the sensor cannot be reached, but other clients on the same subnet are still accessible.

What are two reasons for the connectivity problem? (Choose two.)

The given scenario suggests that the sensor is not able to send data to the configured destination when a different subnet is used. However, the IP address of the sensor can be pinged from a laptop on the same subnet, indicating that the problem is related to the network configuration.

To resolve the connectivity problem, we need to identify the possible reasons for it. The options given in the question are:

A. Wrong DNS server on the sensor B. Wrong subnet mask on your laptop C. Wrong default gateway on the sensor D. Wrong default gateway on your laptop E. Wrong subnet mask on the sensor

Out of these options, the two possible reasons for the connectivity problem are:

C. Wrong default gateway on the sensor: The default gateway is a device that connects the local network to other networks or the internet. It acts as an intermediary between the local network and external networks. If the default gateway on the sensor is wrong, the sensor won't be able to send data to the configured destination when a different subnet is used. However, other clients on the same subnet will still be accessible. To fix this issue, the correct default gateway needs to be configured on the sensor.

E. Wrong subnet mask on the sensor: The subnet mask is used to identify the network portion and the host portion of an IP address. If the subnet mask on the sensor is wrong, it may not be able to communicate with devices on a different subnet. This could be the reason why the sensor cannot be reached when a different subnet is used. To resolve this issue, the correct subnet mask needs to be configured on the sensor.

The other options, i.e., wrong DNS server on the sensor, wrong subnet mask on your laptop, and wrong default gateway on your laptop, are not related to the given scenario and are therefore incorrect.

In conclusion, the two possible reasons for the connectivity problem are the wrong default gateway on the sensor and the wrong subnet mask on the sensor.
