Sites overview
Sites in AD DS represent the physical structure, ortopology, of your network. AD DS uses network topology
information, which is stored in the directory as site, subnet, and site link objects, to build the most efficient
replication topology. The replication topology itself consists of the set of connection objects that enable inbound
replication from a source domain controller to the destination domain controller that stores the connection
object. The Knowledge Consistency Checker (KCC) creates these connection objects automatically on each
domain controller. http://technet.microsoft.com/en-us/library/cc754697.aspx
******************************************************************************************
You need to recommend changes to the Active Directory site topology to support on the company’s planned
changes.
Planned Changes
The company plans to implement the following changes:
· Create a child domain named sales.contoso.com. Only the domain controllers in sales.contoso.com willhost a
zone for the sales.contoso.com domain. The domain controllers in sales.contoso.com will run Windows Server
2012. The client computers in sales.contoso.com will use the sales.contoso.com domain controllers as their
DNS servers.
· Implement two servers in the Amsterdam office andtwo servers in the Paris office to replace PA1 andAMI.
These new servers will run Windows Server 2012 and will not have shared storage.
· Decommission the research.contoso.com domain. Allof the users and the Group Policy objects (GPOs) in
research.contoso.com will be migrated to contoso.com.
· Migrate the existing print queues to virtualized instances of Windows Server 2012.
· Migrate the file servers to new servers that run Windows Server 2012.
· Implement RADIUS authentication for VPN connections.
· Deploy Windows Server 2012 to all new servers.
What should you include in the recommendation?
A.
A new site link bridge
B.
A new subnet
C.
A new site link
D.
A new site
You don’t need another subnet. You can use the existing one for migration to IPv6.
On dual-stack systems (ones with both IPv4 and IPv6 stacks active), you can represent IPv4 using IPv6 mechanics. They call it “IPv4-mapped IPv6 addresses”. The pattern is all-zeroes, followed by FFFF, followed by the 32-bit IPv4 address.
So, 192.168.100.21 becomes ::FFFF:C0A8:6415 — or more simply: ::FFFF:192.168.100.21. Since that right-hand bit represents an IPv4 address, it’s traditionally written out using dotted-decimal form.
As this is an actual IPv4 address, it still uses IPv4 headers etc., which means that an IPv4 stack must be present, IPv4 routes must be set, and all that. The advantage is that you can represent both IPv4 and IPv6 addresses using a single address structure.
So D (A new site) is the correct answer.
I would also choose D: New Site.
It says in the Existing AD Environment that each office has its own site.
So the new Sales (office) should be put in a new site also.
If anyone has a differt explanation….
