100-150 Question 223
Single answerYou are troubleshooting a connectivity issue on a network device. You run the command ping 192.168.1.1 and receive the following output:
PING 192.168.1.1 (192.168.1.1): 56 data bytes
--- 192.168.1.1 ping statistics ---
5 packets transmitted, 0 packets received, 100% packet loss
What is the most likely issue based on the command output?
- A
The target device is powered off or not reachable.
- B
The target device has an incorrect subnet mask.
- C
The default gateway on the source device is misconfigured.
- D
The DNS server is not responding.
Show answer and explanation
Correct answer: A
Explanation
The ping command tests basic connectivity between two devices. A 100% packet loss indicates that the target device is not responding to ICMP Echo Requests, which is often due to the device being powered off, disconnected, or otherwise unreachable. Other issues, such as subnet mask or gateway misconfigurations, are less likely based on the information provided.
- A. Correct.
A 100% packet loss in a ping test typically indicates that the target device is either powered off or not reachable due to a network issue like a disconnected cable or incorrect IP configuration.
- B. Incorrect.
Although an incorrect subnet mask could cause communication issues, the ping test would not directly indicate this as the reason for the packet loss.
- C. Incorrect.
A misconfigured default gateway would prevent the source device from reaching devices outside its local network. However, this scenario does not specify whether the target device is within the same subnet or not.
- D. Incorrect.
DNS is unrelated to this scenario since the ping command is using a direct IP address, bypassing any need for DNS resolution.
