MCTS 70-640 Research & Evidence-Based Practice 4

Question 1

Based on Microsoft best practice research, what is the recommended AD DS forest design when an organization requires complete administrative isolation between two business units?

Accepted Answer

Separate forests for each business unit

Answer

Complete administrative isolation requires separate forests because forest-level boundaries are the only true security boundary in AD DS.

Question 2

Microsoft's recommended evidence-based practice for placing domain controllers in a branch office with fewer than 25 users and limited WAN bandwidth involves which role?

Accepted Answer

Read-Only Domain Controller (RODC)

Answer

RODCs host a read-only copy of AD, preventing credential theft risks at insecure branch locations while still providing local authentication.

Question 3

When researching the impact of enabling the Active Directory Recycle Bin in Windows Server 2008 R2, which prerequisite functional level must be met?

Accepted Answer

Windows Server 2008 R2 Forest Functional Level

Answer

The AD Recycle Bin requires Windows Server 2008 R2 Forest Functional Level, which means all DCs in all domains must run Windows Server 2008 R2 or later.

Question 4

Research shows that bridgehead server failures cause entire site replication to stall. What is the evidence-based best practice to prevent a single point of failure?

Accepted Answer

Allow AD to use automatic bridgehead server selection rather than manually designating preferred bridgehead servers

Answer

Manual preferred bridgehead designation creates a single point of failure; automatic selection lets the ISTG elect multiple candidates and failover automatically.

Question 5

Evidence from Microsoft guidance indicates that placing all five FSMO roles on a single domain controller is acceptable only under which condition?

Accepted Answer

In a single-domain forest with only one domain controller

Answer

In a single-DC environment all five FSMO roles must reside on that one DC; in multi-DC environments roles should be distributed according to best practice.
