IT Interview Questions:What FSMO placement considerations do you know of? FSMO availability and placement

Dcpromo.exe performs the initial placement of roles on domain controllers. This placement is often correct for directories with few domain controllers. In a directory with many domain controllers the default placement is unlikely to be the best match to your network. On a per-domain basis, select local primary and standby FSMO domain controllers in case a failure occurs on the primary FSMO owner. Additionally, you may want to select off-site standby owners in the event of a site-specific disaster scenario. Consider the following in your selection criteria:
If a domain has only one domain controller, that domain controller holds all the perdomain roles.
If a domain has more than one domain controller, use Active Directory Sites and Services Manager to select direct replication partners with persistent, "wellconnected" links.
The standby server may be in the same site as the primary FSMO server for faster replication convergence consistency over a large group of computers, or in a remote site in the event of a site-specific disaster at the primary location.
Where the standby domain controller is in a remote site, ensure that the connection is configured for continuous replication over a persistent link.
