You need to design a DNS implementation strategy for Mondo Transport, Ltd. You
need to ensure that your solution meets the business and technical requirements of
the company.

What should you do?

A. Configure a secondary zone of the bilco.com domain on a domain controller in each
office.
B. Configure the DNS Server service on a domain controller in each office and configure
an Active Directory-integrated zone to replicate to all DNS servers in the domain.
C. Configure an Active Directory-integrated zone on a domain controller in the Moscow
office and configure this zone to replicate to the domain controllers in the branch offices.
D. Configure a primary zone for mondo.com on a domain controller in the Moscow
office. Configure a secondary zone on separate DNS server in the Moscow office.

Explanation: When you are running the DNS server service on a computer that is
an Active Directory domain controller and you select the Store The Zone In Active
Directory (Available Only If DNS Server Is A Domain Controller) check box while
creating a zone in the New Zone Wizard, the server does not create a zone database
file.
350-001 Instead, the server stores the DNS resource records for the zone in the Active
Directory database.640-802 Storing the DNS database in Active Directory provides a
number of advantages, including ease of administration, conservation of network
bandwidth, and increased security.VCP-310 In Active Directory-integrated zones, the zone
database is replicated automatically, along with all other Active Directory data.
Active Directory uses a multiple master replication system so that copies of the
database are updated on all domain controllers in the domain. You don't have to
create secondary zones or manually configure zone transfers, because Active
Directory performs the database replication automatically.

This solution satisfies the requirements of the case study, which states: "Our DNS
information must remain secure." As well as "Faster name resolution is required when
connecting to internal servers and external Web sites".

Furthermore, it also states: "Redundancy for any service must be provided if a single
service fails."

Providing redundancy:-For a network that relies heavily on DNS name resolution,
having a single DNS server means having a single point of failure. You should deploy a
sufficient number of DNS servers so that at least two copies of every zone are always
online.
