An administrator mistakenly shutdown production after a fallover because the service IP address Was shifted from the normal production node to the standby node. What can be done to avoid this type of mistake in the future？（） A、 Include the service IP address in the administrator’s PS1 promptB、 Alias the service IP address to the hostname in the /etc/host fileC、 Define a persistent IP address with HACMP and make it a practice to use the persistent address for administration workD、 Add a DNS entry to map the standby node name to the service IP address so telnet connections will be to the correct node
