Network Commands Flashcards
What is the most basic command tool for testing connectivity to other hosts?
ping
What command tool sends an Internet Control Message Protocol (ICMP) echo request to a host and listens for a reply?
ping
With a ping command, if a reply is received from the ICMP echo request, what two things will be displayed?
Time it took and Time to Live (TTL) left
What network command has many options for seeing attributes of a request like the maximum TTL, IPv4/IPv6, and the numbers of requests to send that is useful in troubleshooting connectivity with other devices?
ping
With a ping command, if a reply is not received from the ICMP echo request, what will you receive?
a timeout message
A ping’s timeout message could indicate one or both of these issues?
Connectivity issues and/or firewall issues
Due to the time it takes to get a response from a ping request, the what between two devices can be measured that enables network engineers to troubleshoot performance problems?
latency
What network commands is used to trace the IP route an IP packet takes to a destination?
traceroute/tracecert
What network command displays each hop (next router) in a numerical list with the hop’s IP address and the time it takes to receive the packet?
traceroute/tracecert
With traceroute/tracecert, what command is used for Linux systems and what is used for Windows?
Linux - traceroute
Windows - tracecert
What network command can be useful when a ping fails, troubleshooting performance issues, and other aspects regarding connectivity?
traceroute/tracecert
What network commands is similar to traceroute or tracecert in that it displays the path taken by a packet from its source to its destination?
tracepath
What network command is useful because it can be used by any user instead of needing superuser privilege and primarily used in Linux?
tracepath
What network commands provides the user with the IP, subnet mask, and default gateway for each network adapter by default with the /all option information, such as MAC address, DHCP status, and lease information?
ipconfig (internet protocol configuration)
What network command can be used to release all connections and renew all adaptors that are primarily used in Windows?
ipconfig/release
What network command is used to the configure the kernel network interface, implemented at the time of booting to configure the necessary interfaces?
ifconfig
What linux network command occurs once the interfaces are configured, it is used for debugging or timing the system?
ifconfig
