Common mistakes.

  • B. Changing the organization name of the Cisco SD-WAN fabric is a fabric-wide identifier and does not directly configure the certificate authorization mode for controller trust.
  • C. Simply selecting a Cisco-recommended Controller Certificate Authorization mode does not, by itself, indicate or establish trust for a specific root certificate without the underlying certificate management actions.
  • E. Selecting a validity period is part of certificate generation, but it is not one of the two primary actions required to set the authorization mode to indicate the use of a root certificate.
