100-150 Question 131
Select 4You are troubleshooting a network connectivity issue for a remote worker who uses various devices. The worker reports that they cannot access any websites. Which of the following steps should you take to verify network connectivity on their devices?
- A
Run the 'ping' command on their Windows device to check connectivity to an external server (e.g., 8.8.8.8).
- B
Use the 'Network Utility' tool on their Mac OS device to perform a traceroute to an external website.
- C
Check the 'Wi-Fi' section in the Settings app of their Apple iOS device to confirm if it shows 'Connected'.
- D
Open a terminal on their Linux device and use the 'nslookup' command to verify DNS resolution.
- E
On their Android device, go to Settings > Network & Internet > Airplane Mode and enable it to reset the network connection.
Show answer and explanation
Correct answers: A, B, C, D
Explanation
When troubleshooting network connectivity issues on multiple devices, it is important to use platform-specific tools and methods to verify connectivity. The 'ping' command, traceroute, checking Wi-Fi settings, and verifying DNS resolution are all standard practices for diagnosing network issues. Enabling Airplane Mode is not a direct method for verifying connectivity, but rather a way to reset the network state, making it less relevant in this scenario.
- A. Correct.
Running the 'ping' command on a Windows device is a common troubleshooting step to verify if the device can reach external servers. It helps identify basic connectivity issues.
- B. Correct.
Using the 'Network Utility' tool on Mac OS to perform a traceroute helps identify where the connection might be failing along the path to an external website.
- C. Correct.
Checking the 'Wi-Fi' section in the Settings app on Apple iOS devices is a valid step to confirm if the device is connected to a network. If not connected, this could explain the lack of internet access.
- D. Correct.
Using the 'nslookup' command on Linux devices verifies DNS resolution, which is crucial for internet connectivity. If DNS resolution fails, it could indicate a problem with the DNS configuration.
- E. Incorrect.
Enabling Airplane Mode on an Android device disconnects and reconnects all wireless connections. However, this is not a recommended step for verifying connectivity; it is more useful for resetting the network state.
