  1. Singh says:

    The correct answer should be (B), Conditional Forwarder.
    It can’t be (D), Zone Delegation. The question failed to mention any of the points below.

    When you are deciding whether to divide your DNS namespace to make additional zones, consider the following reasons to use additional zones:
    You want to delegate management of part of your DNS namespace to another location or department in your organization.

    You want to divide one large zone into smaller zones to distribute traffic loads among multiple servers, improve DNS name resolution performance, or create a more-fault-tolerant DNS environment.

    You want to extend the namespace by adding numerous subdomains at once, for example, to accommodate the opening of a new branch or site.

    Actually D is correct.

    Because contoso.com already exists on server 1, a conditional forwarder will not work as server 1 has the ability to provide an authorative answer to things in the contoso.com domain. Forwarders only come into play when the zone is not hosted locally. In this case, delegation is neccessary to tell server 1 to ignore the requests for ad.contoso.com and pass them on to server 2.
