A GIS administrator is installing Portal for ArcGIS and ArcGIS Server on separate machines. They need services to run continuously and comply with…

For a multi-machine ArcGIS Enterprise deployment, a domain account is necessary for the software components to communicate and access shared network resources. A group-managed service account (gMSA) is the recommended type of domain account for this purpose. A gMSA is managed by the domain controller, which handles password management automatically. This ensures that services can run continuously without interruption from password expiration policies, directly fulfilling the requirements of the scenario. Using a gMSA is a security best practice for enterprise environments.

A. A GIS administrator account: Using a personal administrator account is not best practice. If the administrator's password expires or the account is disabled, the ArcGIS services will fail.

C. Create local accounts for every machine being used: Local accounts do not have permissions to access network shares on other machines, which is a requirement for a distributed ArcGIS Enterprise deployment.

D. Windows built-in account with local admin privileges: Built-in accounts, such as the Local System account, have extensive local privileges but limited network access capabilities, making them unsuitable for multi-machine deployments.
