  Important AZ-104 exam distinctions

  Requirement	Command
  Check VM IP address	ipconfig /all
  Test basic connectivity	ping <IP-address>
  Check DNS resolution	nslookup <domain>
  Test a specific TCP port	Test-NetConnection <host> -Port 443
  Check listening ports and connection states	netstat -an
  Identify the process using a connection	netstat -ano
  Find the process name from a PID	tasklist /FI "PID eq 1234"
  Trace the route to a destination	tracert <hostname>
  Clear DNS cache	ipconfig /flushdns
  Inspect network routes	route print
  Check network adapter status	Get-NetAdapter
  Inspect DNS resolution details	Resolve-DnsName <domain>

  Remember: ping tests ICMP connectivity, while Test-NetConnection -Port tests TCP connectivity to a specific port. A failed ping does not necessarily mean the destination is unreachable because ICMP may be blocked by a firewall or network security rule.
