Answer B is correct because only domain joined computers are facing autodiscover problem. On internal network, only autodiscover SCP object created in AD is responsible to resolve autodiscover query. Although SCP object in AD should have gone after decommission of on-prem exchange server but if it not removed for some reason then autodiscover problem will occur domain joined users.

Correction - since we have to select two options then I will go with B and C Answer B and C are correct because only domain joined computers are facing autodiscover problem. On internal network, only autodiscover SCP object created in AD is responsible to resolve autodiscover query. Although SCP object in AD should have gone after decommission of on-prem exchange server but if it is not removed for some reason then autodiscover problem will occur for domain joined users.

If Server 1 was decomissioned you don't have any supported option to change the autodiscover SCP. Supposing that as part of the decomissioning the SCP was removed, i'll go with B and E

Correction. There's no reason for an autodiscover A record in corp.contoso.com. The only answers (but not completely correct) can be B and C.

Correct. The corp.contoso.com won't be hosting the autodiscover record. It just forwards the DNS queries to parent domain contoso.com which is a public domain. Although SCP should have got removed during decommission, there are no other best answers I could see...

Most companies have split DNS. There are several factors left out of the question that completely drives how this questions should be answered in the real world.

I would have thought BC. With primary email domain being contoso.com, it would look for SCP then Autodiscover name resolution in Contoso domain. It would also make sense to have an internal dns zone for contoso.com pointing to internal autodiscover?
