Microsoft 70-411 Exam – Q76

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.

Correct Answer: C, D

Explanation:

Target priority
You can assign a priority to individual targets for a given namespace root or folder. This priority determines how the target is ordered in a referral. The options are:
– First among all targets
– Last among all targets
– First among targets of equal cost
– Last among targets of equal cost

It is important to note that setting target priority on a target will result in that target always being present in a referral, even in cases where you set the Exclude targets outside of the client’s site option on the folder associated with the target.

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.

Referral ordering

A referral is an ordered list of targets, transparent to the user, that a client receives from a domain controller or namespace server when the user accesses the namespace root or a folder with targets in the namespace. The client caches the referral for a configurable period of time.

Targets in the client’s Active Directory site are listed first in a referral. (Targets given the target priority “first among all targets” will be listed before targets in the client’s site.) The order in which targets outside of the client’s site appear in a referral is determined by one of the following referral ordering methods:
– Lowest cost
– Random order

Exclude targets outside of the client’s site
You can set referral ordering on the namespace root, and the ordering method applies to all folders with targets in the namespace. You can also override the namespace root’s ordering method for individual folders with targets.

If you do not want clients to access folder targets outside of their site, you can override the ordering method for individual folders. To do this, right-click a folder with targets in the console tree, click Properties, click the Referrals tab, and then click Exclude targets outside of the client’s site. Note that if no same-site targets are available, the client fails to access the folder because no folder targets are returned in the referral.
