The RID Master holds the global RID pool for the domain. The size is limited to 30-bits by default, so the maximum RID size is 2 to the power of 30, or about one billion. The RID Master assigns each Domain Controller a pool of RIDs to use for SID creation. By default, DCs are assigned 500 contiguous RIDs at a time and request a standby pool containing another 500 RIDs when they have used 50% of their original allocation. If a RID master is not online, the DC promotion cannot complete.

None, I would have said? The only answer that remotely makes sense is B, for the PDC emulator role...

I agree, I searched but didn't find anything saying you can't promote a new DC without the domain naming master being online.

Selected Answer: A RID Domain - Allocates active and standby RID pools to replica domain controllers in the same domain. - Must be online in the following situations: when newly promoted domain controllers must obtain a local RID pool that's required to advertise when existing domain controllers must update their current or standby RID pool allocation.

The correct answer is C: Only an active Domain Naming Master can add, remove, and update domains within AD. Ref: https://www.31west.net/blog/what-are-the-roles-of-active-directory/#:~:text=Another%20forest%2Dlevel%20role%20in,assigned%20to%20a%20single%20DC.

Schema master : responsible for the schema = NO Domain naming master : DCs contact the FSMO role holder when: Domains are added or removed in the forest. New instances of application directory partitions on DCs are added. For example, a DNS server has been enlisted for the default DNS application directory partitions. = YES RID master : Give SID and RID to other DC = NO PDC emulator : time master + The PDC emulator performs all of the functionality that a Windows NT 4.0 Server-based PDC or earlier PDC performs for Windows NT 4.0-based or earlier clients. = YES Infrastructure master : relation with external domains = NO DC2 holds both roles ==> B https://learn.microsoft.com/en-us/troubleshoot/windows-server/identity/fsmo-roles

right, RID Master should be online. here is link from Microsoft: https://learn.microsoft.com/en-us/troubleshoot/windows-server/active-directory/fsmo-placement-and-optimization-on-ad-dcs RID Domain - Allocates active and standby RID pools to replica domain controllers in the same domain. - Must be online in the following situations: when newly promoted domain controllers must obtain a local RID pool that's required to advertise; when existing domain controllers must update their current or standby RID pool allocation.

I'd say DC1 for the RID role: when newly promoted domain controllers must obtain a local RID pool that's required to advertise. We're only adding a DC, not creating a new domain in the forest so the Domain Naming Master can be offline.

Follow these general steps before you promote a server to a DC that runs a newer version of Windows Server: Verify the target server meets the system requirements. Verify application compatibility. Review recommendations for moving to a newer version of Windows Server. Verify security settings. Check connectivity to the target server from the computer where you plan to run the installation. Check for availability of the necessary Flexible Single Master Operation (FSMO) roles in Active Directory. This step is required for the following scenarios: To install the first DC that runs the latest Windows Server version in an existing domain and forest, the machine where you run the installation needs connectivity to: The schema master to run adprep /forestprep. The infrastructure master to run adprep /domainprep. https://learn.microsoft.com/en-us/windows-server/identity/ad-ds/deploy/upgrade-domain-controllers So answer A

Domain Naming Master (Forest Role) If the Domain Naming Master role holder is lost, domains won’t be able to be added or removed from the Active Directory forest. DCPROMO is also affected, meaning that servers can neither be promoted nor demoted.

OK - Never the obvios answer- the domain naming master names domains - not domain controllers- so - the only one that "may" be needed is the Rid MASTER - so a the 2012 server https://social.technet.microsoft.com/Forums/windows/en-US/55cdc487-c3c4-4090-9c41-38d768fb26e8/which-fsmo-role-is-responsible-for-adding-a-new-domain-controller-in-the-existing-root-domain-or#:~:text=There%20are%20no%20FSMO%20roles%20needed%20or%20required,is%20asking%20about%20adding%20domain%20controllers%2C%20not%20domains.

Entry number 23 under ,,Promotion and demotion failure codes'' in your source: https://learn.microsoft.com/en-us/windows-server/identity/ad-ds/deploy/troubleshooting-domain-controller-deployment Implies that the server carrying out the DNS role must be online, but we cannot really infer from this assignment that DC3 is hosting that role, just the DNS FSMO

Nothing super concrete I could find, but similar to Sizz's sources, it does seem RID is a necessary part to DC promotion. This link described it well: https://adamtheautomator.com/fsmo-roles/#DC_PromotionDemotion

Well, one of the answer will be counted as correct obviously, so thanks for providing a clue here. (The link for this, by the way, is this: https://convergenttechonline.com/news/effects-of-losing-an-operations-master-fsmo-role-holder-in-relation-to-an-active-directory-forest-andor-domain/) I do still doubt that this is correct, as Microsoft themselves don't mention anything about this in their outline of the domain naming master role: https://learn.microsoft.com/en-us/troubleshoot/windows-server/identity/fsmo-roles. I mean, this would be a major constraint, why not name it explicitly? But well, better a some indication than no idea at all, I guess. Thanks again!

It's not a new child domain being added, just a DC to an existing domain. All being said, troubleshooting error codes for promotion show two possible errors: 89 (RID master for the specified domain is offline) and 90 (Domain naming master is offline). https://learn.microsoft.com/en-us/windows-server/identity/ad-ds/deploy/troubleshooting-domain-controller-deployment I'd agree with other comments though - technically any role holder should be online for this kind of event, and whichever source DC is being used to replicate if the new DC is being dropped into another site.
