Network Command Proficiency Quiz

When using the `ping` command to test reachability, what does the `-t` option do?

• Sends a specified number of echo requests

• Pings continuously until stopped with Ctrl-c

• Displays the time taken for each packet

• Resolves the IP address to a hostname

How does the `traceroute` command determine the route a packet takes to a destination?

• By sending packets with increasing TTL values and listening for ICMP Time Exceeded messages

• By sending a single packet and waiting for a response

• By querying DNS servers for routing information

• By capturing packets and analyzing their headers

What is a strategic approach to analyze packet loss using the `ping` command?

• Use `ping -n 1` to send a single packet and check for loss

• Use `ping -t` to continuously monitor packet loss over time

• Use `ping -n 100` to send multiple packets and calculate the percentage of lost packets

• Use `ping` without any options to get a quick overview

Which command would you use to capture packets in real-time for network troubleshooting?

• `netstat`

• `tcpdump`

• `traceroute`

• `nslookup`

What is the purpose of using the `ipconfig /flushdns` command in network troubleshooting?

• To release the current DHCP lease

• To renew the DHCP lease

• To clear the DNS resolver cache

• To display all IP configuration details

How can the `traceroute` command help in diagnosing network issues?

• By showing the path packets take and identifying where delays occur

• By displaying all active network connections

• By resolving IP addresses to hostnames

• By capturing and analyzing packet data

What strategic method can be used to interpret the output of a `traceroute` command?

• Look for the first hop to determine the source of the problem

• Identify the hop with the highest latency to find potential bottlenecks

• Focus on the last hop to determine the destination's response time

• Ignore hops that do not respond

Which command would you use to view the local ARP table for troubleshooting purposes?

• `ipconfig /all`

• `arp -a`

• `netstat -a`

• `ifconfig`

What is the strategic importance of using `netstat -b` in network troubleshooting?

• To show all active connections

• To display the binaries associated with each connection

• To prevent name resolution

• To capture packets in real-time

How can the `ipconfig /release` and `ipconfig /renew` commands be used strategically in network troubleshooting?

• To clear the DNS cache and resolve new addresses

• To reset the network adapter and obtain a new IP address from the DHCP server

• To display all current IP configuration details

• To capture and analyze network packets
