Your company has a main office and two branch offices. The main office is located in
Seattle. The two branch offices are located in Montreal and Miami. Each office is configured
as an Active Directory site.
The network contains an Active Directory domain named contoso.com. Network traffic is not
routed between the Montreal office and the Miami office.
You implement a Distributed File System (DFS) namespace named \\contoso.com\public.
The namespace contains a folder named Folder1. Folder1 has a folder target in each office.
You need to configure DFS to ensure that users in the branch offices only receive referrals
to the target in their respective office or to the target in the main office.
Which two actions should you perform? (Each correct answer presents part of the solution.
Choose two.)
A.
Set the Ordering method of \\contoso.com\public to Random order.
B.
Set the Advanced properties of the folder target in the Seattle office to Last among all
targets.
C.
Set the Advanced properties of the folder target in the Seattle office to First among
targets of equal cost.
D.
Set the Ordering method of \\contoso.com\public to Exclude targets outside of the client’s
site.
E.
Set the Advanced properties of the folder target in the Seattle office to Last among targets
of equal cost.
F.
Set the Ordering method of \\contoso.com\public to Lowest cost.
Explanation:
Exclude targets outside of the client’s site
In this method, the referral contains only the targets that are in the same site as the client.
These same-site targets are listed in random order. If no same-site targets exist, the client
does not receive a referral and cannot access that portion of the namespace.
Note: Targets that have target priority set to “First among all targets” or “Last among all
targets” are still listed in the referral, even if the ordering method is set to Exclude targets
outside of the client’s site .
Note 2: Set the Ordering Method for Targets in Referrals
A referral is an ordered list of targets that a client computer receives from a domain
controller or namespace server when the user accesses a namespace root or folder with
targets. After the client receives the referral, the client attempts to access the first target in
the list. If the target is not available, the client attempts to access the next target.

This documentation says “Targets that have target priority set to “First among all targets” or “Last among all targets” are still listed in the referral, even if the ordering method is set to Exclude targets outside of the client’s site.”
This would lead you to believe that while D is necessary to prevent it going out of site, both B and C would accomplish the task of including the main site in the list of referrals.
Since it looks in-site first, it wont matter what order is the out of site referrals since there will only be the main site.
So shouldn’t the answers be B and D? D excludes all non-site targets and B lists the Seattle target even though it is a non-site target?
Per the link, only targets set to ‘first among all targets’ or ‘last among all targets’ are listed, not ‘first among targets of equal cost’.
D) set the global Setting that clients just get referrals in their site
B) make an exclusion to the global Setting. Site First, Main Office last

Agree it is definitely B, D.
It is b and d
https://technet.microsoft.com/en-us/library/cc772778%28v=ws.10%29.aspx
It should be C + D, Because you want the branches always to fail over to the main office if the local site is not available.
https://technet.microsoft.com/en-us/library/cc772778%28v=ws.10%29.aspx
1 The client in the branch site attempts to access a folder target on the local server, but the server is unavailable.
2. The client attempts to fail over to one of the two servers in the hub site. If you want clients to always fail over to a particular server in the hub site, you can configure that hub server’s target priority as first among targets of equal cost. The client attempts to fail over to this preferred hub server first.
in the link you post is the exact scenario as this question:
If you want to prevent branch clients from failing over to a branch server at a different branch site, select the Exclude targets outside of the client site ordering method for each folder with targets, and then set target priority on each hub server’s folder target by selecting the Last among all targets target priority. The result of selecting these two options is as follows:
• The Exclude targets outside of the client site setting ensures that only targets within the client’s site will be included in referrals.
• The Last among all targets setting overrides the referral ordering method by including the hub server in the referral, even if the hub server is not in the client’s site. (If multiple hub servers are used as folder targets for a given folder, those hub servers will appear last in the referral and be sorted in order of lowest cost after the other targets.)
So definitely B and D.

c and D
according to your link it should be:
B and D
“Targets that have target priority set to “First among all targets” or “Last among all targets” are still listed in the referral, even if the ordering method is set to Exclude targets outside of the client’s site.”
=> using “last among all targets” combined with “excelude…” should do it for the failover feature
This is a BS question because of the vagueness: “ensure that users in the branch offices only receive referrals to the target in their respective office OR to the target in the main office.”
Answer D is a given because all links provided here reference this fact:
“Targets that have target priority set to “First among all targets” or “Last among all targets” are still listed in the referral, even if the ordering method is set to Exclude targets outside of the client’s site.”
BUT because there is no indication on what the priority should be to the main office; B, C, & E are all technically valid.
Agreed
I’m mistaken, this one is B & D. I missed that it it has to be “First among ALL targets” or “Last among ALL targets”. Sorry to add to the confusion.
It’s B and D
Reference:
“If you want to prevent branch clients from failing over to a branch server at a different branch site, select the Exclude targets outside of the client site ordering method for each folder with targets, and then set target priority on each hub server’s folder target by selecting the Last among all targets target priority. The result of selecting these two options is as follows:
The Exclude targets outside of the client site setting ensures that only targets within the client’s site will be included in referrals.
The Last among all targets setting overrides the referral ordering method by including the hub server in the referral, even if the hub server is not in the client’s site. (If multiple hub servers are used as folder targets for a given folder, those hub servers will appear last in the referral and be sorted in order of lowest cost after the other targets.)”

Answer is definitely C, F
F. Lowest cost ensures that the it uses the server in the same site since it has a lower cost then the main office and definitely lower then the other branch office.
and c sets the main office as first option among sites of equal cost.

Problem is the question doesn’t say whether you want to use the branch office or the main office first.
The correct answers are C & D.
The ordering method is first set to ‘Exclude targets outside of the client’s site’, also known as the INSITE ordering method. As Technet states: ‘Targets that have target priority set to “First among all targets” or “Last among all targets” are still listed in the referral, even if the ordering method is set to Exclude targets outside of the client’s site.’
We can then assume that the Montreal and Miami branch offices have an equal cost to that of the Seattle main office. This means that in the referral for a client at each site they will be pointed to the Seattle site first and THEN to their own site. The INSITE ordering method will exclude any sites outside of the client site UNLESS they are explicitly set to be first or last among all targets.
Although, this article – https://blogs.technet.microsoft.com/askds/2011/10/27/dfs-override-referral-ordering-messing-with-the-natural-order/ – states:
‘Lastly, First/Last Among Targets of Equal Cost have no effect when INSITE is set.’
Has anyone tested this?
Correction, the answer is B & D. Override Referral Ordering of’First/Last Among Targets of Equal Cost’ doesn’t work with the ‘INSITE’ ordering method set. I’ve tested this multiple times in a test environment – only ‘First/Last Among All Targets’ places an entry in the clients DFS cache.
