Zorluk: OrtaWindows Client Networking Configuration

A Windows 11 desktop computer is experiencing persistent connectivity issues following a router migration. A help desk technician needs to purge the local DNS resolver cache to remove stale IP address mappings and reset the IPv4 protocol stack to its default state to resolve protocol stack corruption. Which of the following commands should the technician execute on the client machine? (Select TWO.)

  1. ipconfig /flushdnsCevap
  2. netsh int ip resetCevap
  3. C
    ipconfig /resetip
  4. D
    netsh dns flush

Cevap

The technician must execute `ipconfig /flushdns` to purge stale host name records from the local resolver cache and `netsh int ip reset` to restore the TCP/IP protocol stack to its clean default configuration.
Executing `ipconfig /flushdns` flushes obsolete address entries stored in the local client cache. Executing `netsh int ip reset` resets the TCP/IP interface stack by overwriting registry keys controlling network protocols, resolving protocol layer corruption.

Adım Adım Çözüm

1
Identify the command required to clear cached local DNS resolver entries.
The `ipconfig /flushdns` command empties the local DNS cache so the client performs fresh DNS queries.
Outdated host-to-IP mappings cause routing failure to local or remote host names after router reconfigurations.
2
Identify the command required to reset the TCP/IP stack configuration.
Executing `netsh int ip reset` rewrites registry keys controlling TCP/IP settings to defaults.
Protocol stack corruption prevents stable socket operations, requiring a reset of the network stack.
