A network technician is performing tests on a potentially faulty network card that is installed in a server. Which of the following addresses will MOST likely be used during traffic diagnostic tests?
In diagnostic tests for a network card, the address most likely used is 127.0.0.1. This is the loopback address, which refers to the local machine. When data is sent to this address, it is routed back to the same device, allowing the technician to test the software configuration of the network stack without requiring a physical network connection. This helps determine if the TCP/IP stack and associated drivers are functioning properly without relying on external network factors.
correct answer is B, this is the local host
B. 127.0.0.1 The address "127.0.0.1" is the loopback address, which is used to refer to the localhost or the current machine. This address is used for diagnostic tests on the network card or other network interfaces. Because it does not require any physical network connection, it is useful for testing the software configuration of the network stack, such as the IP stack and drivers, without the need for a connection to an external network.
Maybe I'm wrong, but I think you and the questions are all wrong. Pinging a loopback address, which is the entire range of 127.x.x.x, but in this case is specificed as 127.0.0.1 actually just pings the TCP/IP stack itself. You can ping your loopback with no NIC at all. Pinging your loopback does *not* hit your card. What does hit your NIC is pinging your own IP. This questions is absolutely WRONG.
You don't need to test the actual server traffic. The question states that they don't even know if the NIC is working. So to test the NIC you use the loopback address.
The address 127.0.0.1 is the IP address for the loopback address, also known as the "localhost." This address is used for testing network connections and communication within a single device, such as a server. When data is sent to the loopback address, it is routed back to the same device, allowing the network technician to test the network card and other network components without sending traffic over the network.
C. is bait. D is a subnet mask. A. is some random IP that with no given context we cannot know if pinging this would test NIC properly. B. is local host and if you ping local host you can test your NIC. "Pinging localhost, or 127.0.0.1, tests how well your system performs by showing how many data packets are sent, received, or lost, and how long data transmission takes. This can help you determine if your NIC is functioning and if your TCP/IP stack is not corrupt."
It cannot be C as there is no indication of the network using the 192.168.0.0 network. lets say that the company is using 172.20.89.0 instead.... the only address left to test on is the Local Host or the 172.0.0.1 address. Please stop over complicating this for individuals who just need the right answers. Answer is 100% B
127.0.0.1 would only detect traffic going to from the NIC to the loopback address, you can't access the server on a loopback, which is why it would be best to use a basic IPv4 address to troubleshoot the server.
When a network technician is performing traffic diagnostic tests on a network card, they are usually interested in generating traffic and checking the card's functionality. The most likely address to use for such tests is: B. 127.0.0.1 This address is the loopback address, and it is used to test network functionality on the local machine without actually sending traffic out onto the network. It allows you to check the network card's basic functionality without involving external devices or networks.
Localhost also know as 127.0.0.1
The address that will MOST likely be used during traffic diagnostic tests on a potentially faulty network card is 127.0.0.11. This is the loopback address, which is used to test the network interface of a device without sending any packets to the network2. By using the loopback address, a network technician can check if the network card is functioning properly and if the software configuration of the network stack, such as the IP stack and drivers, is correct. The loopback address can be used with various tools, such as ping, tracert, ipconfig, or netstat, to perform different tests on the network card.
Loopback allows you to test your network interface card
B. 127.0.0.1 or loopback is the clear answer for troubleshooting
A. 10.10.10.10 - Private address B. 127.0.0.1 - loopback address C. 192.168.0.1 - private address D. 255.255.255.0 - broadcast address that wouldn't be suitable for testing a single network card.
B doesn't hit the NIC
I dont believe pinging 127.0.0.1 hits the NIC. The ping is just handled within the operating system network stack. You can't test the NIC with localhost pinging.
Why can't it be A??? The sever is within a private network, so either the lopback 127.0.0.1 or the private 10.10.10.10. What do you guys think ?
