Explanation
AutoSupport relies on external network infrastructure to deliver messages; changes to DNS, firewalls, or proxy servers outside the cluster can silently break delivery.
Common mistakes.
- C. Active Directory service accounts govern CIFS/SMB authentication, not AutoSupport message delivery, so changes there have no effect on AutoSupport.
- D. The NetApp support user ID is a web portal credential for human access and is not used by the cluster to authenticate or transmit AutoSupport messages.
Concept tested. AutoSupport external delivery dependencies
