I think, correct answer should be A. According to https://docs.microsoft.com/en-us/azure/dns/dns-delegate-domain-azure-dns Delegate the domain Now that the DNS zone is created and you have the name servers, you need to update the parent domain with the Azure DNS name servers. Each registrar has its own DNS management tools to change the name server records for a domain. 1. In the registrar's DNS management page, edit the NS records and replace the NS records with the Azure DNS name servers. 2. When you delegate a domain to Azure DNS, you must use the name servers that Azure DNS provides...

There are four patterns with this question, please find the answers which is No and the one which is Yes. Solution: You create a PTR record for www in the contoso.com zone. Does this meet the goal? No Solution: You modify the SOA record in the contoso.com zone. Does this meet the goal? No Solution: You add an NS record to the contoso.com Azure DNS zone. Does this meet the goal? No Solution: You modify the name servers at the domain registrar. Does this meet the goal? Yes

You create an Azure DNS zone named contoso.com!!! It should be a custom DNS zone. The problem was not with the registrar, you misconfigure the DNS on azure itself.

wil go for yes Before you can delegate your DNS zone to Azure DNS, you need to know the name servers for your zone. The NS record set contains the names of the Azure DNS name servers assigned to the zone.

I think the goal means name record and not name servers. CNAME (Name record) is using in subdomains.

This is what you need to do: In the registrar's DNS management page, edit the NS records and replace the NS records with the Azure DNS name servers. https://docs.microsoft.com/en-us/azure/dns/dns-delegate-domain-azure-dns#delegate-the-domain

This is another sneaky question if you don't interpret it correctly. Modifying a name server is different than modifying a name server (NS) RECORD. Modifying the NS record at your registrar is what will point it to Azure DNS. The answer is right (B). https://docs.microsoft.com/en-us/azure/dns/dns-delegate-domain-azure-dns

Option A is Correct. If you use Domain Registrars like GoDaddy you have a Separate section for "Nameservers" in Manage DNS option in addition to "Records" section. Here once you modify default servers to Azure Name Server you can see the NS record automatically added to Records section.

I cannot confirm or deny your settings with GoDaddy. With my domain registrar, I have name server records that I can add/modify. I've tested and works for me. However, this is a Microsoft exam and their answers probably prevail. Their answer is confirmed in their own documentation - https://docs.microsoft.com/en-us/azure/dns/dns-delegate-domain-azure-dns I can see where some folks have different registrars and their admin panels can be name differently and hence conflicting answers here.

if by modify means replace with the azure NS servers than the answer is A. if not than its wrong and B is the right answer. not sure what they are trying to convey. just beign overly vague. i am going with A based on what the word " modify" means. make partial or minor changes.

The wording is appropriate and exact here. You modify the NAME SERVERS are your domain registrar basically to point to the Azure DNS Servers. I've validated on my domain registrar and the wording is exactly the same "Modify Name Server for xxxxx.ae" On the next page Q12. Its Add NS Server on Azure DNS which is completely wrong

the wording is tricky, Name servers and Ns records are the same. https://docs.microsoft.com/en-us/microsoft-365/admin/get-help-with-domains/change-nameservers-at-any-domain-registrar?view=o365-worldwide#change-your-domains-nameserver-ns-records

But adding an NS record in Azure DNS will make no difference if the domain registrar is still pointing at the old (or default) NS servers, therefore the NS records need to be updated at the Domain Registrar: https://docs.microsoft.com/en-us/azure/dns/dns-delegate-domain-azure-dns#delegate-the-domain "In the registrar's DNS management page, edit the NS records and replace the NS records with the Azure DNS name servers."

This is different right, it talks about creating aTXT record at domain registrar after you add a custom domain..in this question we are talking about adding entry into Azure DNS & that is not propagating well...hence clients cant connect

It's a trick question. All these questions have funny wording. You don't modify the Name servers at the registrar, you modify the RECORDS.

ns servers also represent NS records. https://docs.microsoft.com/en-us/microsoft-365/admin/get-help-with-domains/change-nameservers-at-any-domain-registrar?view=o365-worldwide#change-your-domains-nameserver-ns-records

The registrar will already have NS records there if you haven't moved them to another DNS provider. So you can modify the records there to point to Azure DNS. I suppose you could delete all of them and add new ones, but in my book, that is modifying. My opinion A is correct here. And since I recently created a personal domain and moved it successfully to Azure DNS doing these steps, then added an A record in Azure DNS to point to a private web server, I'd say I even proved it in a lab.
