1. What are DFS Namespace shared folders referred to in relation to the virtual folders?
ANS: targets
2. What term is defined as "an ordered list of servers or targets that a client computer receives from a domain controller or namespace server when the user accesses a namespace root or a DFS folder with targets"?
	ANS: referral
3. Which of the following tasks does the Event Viewer MMC snap-in allow you to perform?
ANS: Save useful event filters as custom views that can be reused.
4. The Reliability Monitor provides a range of numbers to help you evaluate the reliability of a computer. What is the name of this range of numbers?
	ANS: Stability Index
5. Which command clears the audit policy on a computer?
	ANS: auditpol /clear
6. Placing a quota limit on a folder applies that limit to what part of the folder?
	ANS: the entire folder and its subtree
7. When you create quotas, you are recommended to use what built-in feature to assist you?
	ANS: quota template
8. What technology did Microsoft develop to combat the storage of storage-using and potentially illegal files on corporate servers?
	ANS: File Screening
9.Which screening technique prevents a user from saving defined unauthorized files?
	ANS: Active
10.When storage space is at a premium, what should you do to ensure that everyone has enough space?
	ANS: Set up hard quota limits with e-mail notification.
11. Which Windows technology is used to encrypt a USB disk device?
ANS: BitLocker To Go
12. What FSRM feature can you use to show the state of file server volumes, quotas, and
disallowed rules?
	ANS: Storage Reports
13. If you want to use VPN reconnect, which VPN protocol should you use?
ANS: Internet Key Exchange Version 2 (IKEv2)
14. You have a single DHCP server that services the corporate offic and 25 remote sites. How do you install a DHCP relay agent on a remote site so that you can forward DHCP requests to the DHCP server?
ANS: Install RRAS and enable routing
15. In which audit group do you find the Audit Filtering Platform Connection and Audit Filtering Platform Packet Drop?
ANS: Object access auditing
16. By default, replication groups use what type of topology to replicate to all members of the group?
ANS: full mesh
17. What type of resolution model does DFS Replication use to resolve simultaneous-write conflicts?
ANS: last-writer wins
18. Discuss the function of the reliablity monitor and resource monitor.
ANS:
The Reliability Monitor provides a stability index that ranges from 1 (the least stable) to 10 (the most stable).
Resource Monitor can help you analyze unresponsive processes, identify which applications are using ﬁles, and control processes and services.
19. what types of event contain in security log in event viewer
	ANS:
Account logon
Account management
Directory service access
lognon
object access
20. Discuss and explain two basic encryption algorithms.
ANS: Encryption algorithms can be divided into three classes:
 • Symmetric 
• Asymmetric 
• Hash function 
Symmetric encryption uses a single key to encrypt and decrypt data. Therefore, it is also referred to as secret-key, single-key, shared-key, and private-key encryption. 
Asymmetric key, also known as public-key cryptography, uses two mathematically related keys. One key is used to encrypt the data and the second key is used to decrypt the data. 
21. Purpose of data collector Sets:
ANS: Data Collector Sets (DCS) that allow you to organize a set of performance counts, event traces, and system conﬁ guration data into a single object that can be reused as needed.
22. Explain how differential compression (RDC) works?
ANS: DFS Replication uses a compression algorithm known as remote differential compression (RDC), which detects changes to the data in a ﬁle and replicates only those ﬁ le blocks that changed instead of the entire ﬁ le. As a result, not as much data needs to be transferred. If you disable RDC, you can conserve processor and disk input/output (I/O). Of course, you will consume much more bandwidth.
23. How staging folder work in DFS?
ANS: To figure what needs to be replicated, DFS uses staging folders. The staging folder acts as a cache for new and changed files that need to be replicated. It also is used to compress files that need to be sent. When received on the other end, it is used to decompress the file and install the file into the replicated folder.

24. explain the relationship between DFS replication and DFS namespace.
ANS:DFS Namespaces and DFS Replication role services, which together comprise Distributed File System (DFS) in Windows Server 2012 R2.
DFS can provide redundancy to improve data availability while minimizing the amount of traffic passing over the WAN links. Two technologies in DFS are DFS namespace and DFS replication.
25. Last among targets of equal cost: 
ANS: Speciﬁes that users should never be referred to this target if there are other targets of equal cost available (which usually means other targets in the same site).
26. what happens if you have an EFS encrypted file and you copy the file to a folder that is not encrypted  and on an NTFS volume.
ANS: If you encrypt a file, it is automatically decrypted if you copy or move the file to a volume that is not an NTFS volume. 
27. Why is BitLocker To Go an important technology to use as a standard practice? 
ANS: Because it’s for removable devices, which should always be encrypted because of how easily they’re lost or stolen. 
A new feature in Windows 7 and Windows Server 2008 R2, BitLocker To Go enables users to encrypt removable USB devices, such as flash drives and external hard disks.
