Nutanix Certified Services – Core v6.8 (NCS-Core) — Question 8

A consultant is setting up a new install of Nutanix Files for a customer, but receives this error when attempting to join the customer’s Active Directory domain:
File Server <FileServerName> could not join the Domain because User credentials failed with error - Unable to connect to WORKGROUP ads_connect: No logon servers
The consultant has already verified the domain credentials provided by the customer are valid and have the correct permissions.
What is the most likely cause in this scenario for a domain-join failure when setting up Nutanix Files?

Answer options

• A. The FSVMs storage network must be in the same network as the logon servers.
• B. The client network is failing to communicate with the customer’s domain controllers due to a missing network firewall port requirement.
• C. The FSVMs must first be manually added to a site mapping in Active Directory before they can be authorized to communicate with the logon servers.
• D. The client network is failing to communicate with the customer’s domain controllers due to mismatched MTU sizes.

Correct answer: B

Explanation

The correct answer is B because if the client network cannot communicate with the customer’s domain controllers, it will lead to domain-join failures. Options A and C are incorrect because the FSVMs do not need to be on the same network as the logon servers or manually added to a site mapping to communicate, and option D is incorrect since MTU size issues would typically cause different types of connectivity problems.
