Your network contains an Active Directory forest named contoso.com. The forest contains
two domains named contoso.com and child.contoso.com. The forest contains two domain
controllers. The domain controllers are configured as shown in the following table.
You need to ensure that DC2 can provide authoritative responses for queries to the
contoso.com namespace.
What should you do?
A.
On DC2, create a forwarder.
B.
On DC1, create a delegation.
C.
On DC1, change the replication scope of the contoso.com zone.
D.
On DC2, modify the Zone Transfers settings.
Is the answer is C ?
I believe the answer is corret -DC1 Create delectation

Correct answer here is C
For DC1 to be able to provide authoritative responses to DNS queries the replication scope should be changed accordingly so that it has the zone data for the contoso.com domain.
Answer should be C
Forwarder is incorrect > not authorative
Delegation is incorrect > DC1 already hosts this and can only delegate “subdomains”.
Change replication scope > would be correct if DC2 had the dns role installed.
zone transfer settings > the zone doesn’t exist on dc2 (actually i think it could exist in AD if the zone was marked to replicate to all DC’s in the forest, but since you dont have a DNS server role installed, it doesnt load).
So C bc it’s the least bad.
the dns role is installed by default as dc2 is a domain controller
from MS:
Delegating zones
DNS provides the option of dividing up the namespace into one or more zones, which can then be stored, distributed, and replicated to other DNS servers. When deciding whether to divide your DNS namespace to make additional zones, consider the following reasons to use additional zones:
A need to delegate management of part of your DNS namespace to another location or department within your organization.
A need to divide one large zone into smaller zones for distributing traffic loads among multiple servers, improve DNS name resolution performance, or create a more fault-tolerant DNS environment.
A need to extend the namespace by adding numerous subdomains at once, such as to accommodate the opening of a new branch or site.

Hey Kingces
what you quoted is correct but does not apply to this question as answer A. says On DC1, create a delegation.
DC1 is already authoritative for the domain so a delegation isn’t required
DC2 has to be able to resolve names in Contoso.com domain
for me the answer is C. as we need to replicate the zone information from DC1 to DC2
what do you think if b means to create a delegation on dc1 for dc2 it means dc1 delegate it’s namespace to dc2!
