A company has 10 portable client computers that run windows 8.1.
The portable client computers have the network connections described in the following table+
None of the computers can discover other computers or devices, regardless of which connection they use.
You need to configure the connections so that the computers can discover other computers or devices only while connected to the CorpWired or CorpWifi connections.
What should you do on the client computers?
A. For the CorpWired connection, select Yes, turn on sharing and connect to devices.
B. Change the CorpWired connection to public. Turn on network discovery for the Public profile.
For the Hotsport connection, select No, don’t turn on sharing or connect to devices.
C. For the CorpWifi connection, select Yes, turn on sharing and connect to devices.
D. Turn on network discovery for the Private profile
E. Turn on network discovery for the Public profile
By design Public profile as Sharing set to no and Private profile set to Yes
But it Says "None of the computers can discover other computers or devices, regardless of which
connection they use" so you need to review the full config.

A company has 10 client computers that run Windows 8.1.
Employees log on to resources by using multiple accounts.
You need to back up the user name and password for each logon account.
What should you do on each client computer?
A. Back up each user’s Personal Information Exchange PKCS #12 (.pfx) certificate.
B. Use Credential Manager to save the information to a USB flash drive.
C. Use File History to back up the ntuser.dat file.
D. Run the Export-Certificate Windows PowerShell cmdlet.
Credential Manager – Where Windows Stores Passwords & Login Details
What is the Credential Manager?
Credential Manager is the "digital locker" where Windows stores log-in credentials (username, password, etc.) for other computers on your network, servers or Internet locations such as websites.
Windows 8 adds one more type of credentials called Web Credentials. As the name implies, such credentials are used by Internet Explorer to automatically log you into certain websites.
How to Backup and Restore Windows Vault Passwords
One way to use the Credential Manager is to export your Windows credentials to another Windows computer, or to back them up and import them after you reinstall Windows, so that you don’t have to manually type them again.
Backup Your Windows User Names and Passwords
Open the Credential Manager. Under the Windows Vault look for the "Back up vault" link and click on it.
This starts the Stored User Names and Passwords wizard.
You are asked to select where you want to backup the Windows credentials stored on your computer. Click on Browse, select the folder and type the name of the file where the data will be stored. Then, click Next.
This procedure has been tested both on Windows 7 and Windows 8. In Windows 8, there are some minor differences but it all works the same.

Getting Started with DaRT 8.0
How to Get DaRT 8.0
DaRT 8.0 is a part of the Microsoft Desktop Optimization Pack (MDOP).
MDOP is part of Microsoft Software Assurance.
Overview of the Tools in DaRT 8.0
From the Diagnostics and Recovery Toolset window in Microsoft Diagnostics and Recovery Toolset (DaRT) 8.0, you can start any of the individual tools that you include when you create the DaRT 8.0 recovery image.
Exploring the DaRT tools
The Hotfix Uninstall Wizard lets you remove hotfixes or service packs from the Windows operating system on the computer that you are repairing. Use this tool when a hotfix or service pack is suspected in preventing the operating system from starting.
Use the Crash Analyzer Wizard to quickly determine the cause of a computer failure by analyzing the memory dump file on the Windows operating system that you are repairing. Crash Analyzer examines the memory dump file for the driver that caused a computer to fail. You can then disable the problem device driver by using the Services and Drivers node in the Computer Management tool.
A client computer that runs Windows 8.1 has two hard disk drives: a system drive and a data drive.

A company has client computers that run Windows 8.1.
The client computer systems frequently use IPSec tunnels to securely transmit data.
You need to configure the IPSec tunnels to use 256-bit encryption keys.
Which encryption type should you use?
Descriptions of the IPsec Algorithms and Methods
Data encryption algorithms are used to provide confidentiality to the data payload of an IPsec-protected network packet. Encryption algorithms can be very computationally intensive and can significantly impact computer performance. We recommend that you only encrypt network traffic that requires encryption. If you find that encryption impacts performance more than expected, consider using a network adapter that supports IPsec task offload.
DES is a block cipher encryption protocol that uses a 56-bit key and is documented in Federal Information Processing Standards Publication 46-3 (http://go.microsoft.com/fwlink/?linkid=128014). A block cipher is an encryption algorithm that operates on a fixed size block of data. DES encrypts data in 64-bit blocks using a 64- bit key.
The key appears to be a 64-bit key, but one bit in each of the 8 bytes is used for error checking, resulting in 56 bits of usable key.
Triple-DES or 3DES is an encryption protocol that provides stronger encryption than DES.
It is documented in Federal Information Processing Standards Publication 46-3 (http://go.microsoft.com/fwlink/?linkid=128014). 3DES is a block cipher that uses a three- step encryption process that is more secure than DES. A block cipher is an encryption algorithm that operates on a fixed size block of data.
AES-CBC 128, 192, and 256
The AES in Cipher Block Chaining mode (AES-CBC) encryption algorithms are part of the NSA "Suite B" and are documented in RFC 3602
(http://go.microsoft.com/fwlink/?linkid=127990). AES is documented in Federal Information Processing Standards Publication 197 (http://go.microsoft.com/fwlink/?linkid=127986). The AES algorithm is a symmetric block cipher that can encrypt and decrypt information in data blocks of 128 bits, using cipher keys with lengths of 128, 192, and 256 bits. Longer key lengths provide better security at the cost of CPU performance due to the more intensive computational requirements. Cipher block chaining (CBC) is used to hide patterns of identical blocks of data within a packet. An initialization vector (an initial random number) is used as the first random block to encrypt and decrypt a block of data. Different random blocks are used in conjunction with the secret key to encrypt each successive block. This ensures that identical sets of unsecured data (plaintext) result in unique, encrypted data blocks.
AES-GCM 128, 192, and 256
AES-GCM is both an integrity and encryption algorithm and is described in the Integrity algorithms section.
You are configuring a computer that will be used in a kiosk in a public area. You install a new internal hard drive. You need to protect the computer from starting an unauthorized operating

A desktop computer that runs Windows 8.1 downloads updates but does not install them.
The computer is connected to the corporate network by using a wired network connection.
You need to ensure that the computer automatically installs updates.
What should you do?
A. Set the wired network connection to non-metered.
B. Configure the Automatic Maintenance setting.
C. Enable the Reschedule Automatic Updates scheduled installations Group Policy setting.
D. Set the wired network connection to metered.
Windows depends on execution of inbox and third party maintenance activity for much of its value-add, including Windows Update, and automatic disk defragmentation, as well as antivirus updates and scans.
The goal of Automatic Maintenance is to combine all background maintenance activity in Windows and help third-party developers add their maintenance activity to Windows without negatively impacting performance and energy efficiency. Additionally, Automatic Maintenance enables users as well as enterprises to be in control of maintenance activity scheduling and configuration.
One of the most important maintenance-related improvements in Windows 8 is Automatic Maintenance. This is a new system maintenance service that can be used by Windows components and apps to schedule maintenance activities on the PC in one scheduled window per day.

C: System protection is a feature that regularly creates and saves information about your computer’s system files and settings. System protection also saves previous versions of files that you’ve modified. It saves these files in restore points, which are created just before significant system events, such as the installation of a program or device driver. They’re also created automatically once every seven days if no other restore points were created in the previous seven days, but you can create restore points manually at any time.

Remote Server Administration Tools for Windows 8
Remote Server Administration Tools for Windows 8 enables IT administrators to manage roles and features that are installed on computers that are running Windows Server 2012 from a remote computer that is running Windows 8.
http://searchnetworking.techtarget.com/tip/Perimeter-networks Perimeter networks
A perimeter network is the network closest to a router that is not under your control. Usually a perimeter network is the final step a packet takes traversing one of your networks on its way to the internet; and conversely the first network encountered by incoming traffic from the Internet. Most administrators create perimeter networks in order to place their firewall in between them and the outside world so that they can filter packet traffic. Most perimeter networks are part of the DMZ (Demilitarized Zone) if they exist at all. However, perimeter networks have some additional utilities that you might want to consider when deciding where to place systems and services.
The Enable-PSRemoting cmdlet configures the computer to receive Windows PowerShell remote commands that are sent by using the WS-Management technology.
On Windows Server® 2012, Windows PowerShell remoting is enabled by default. You can use Enable-PSRemoting to enable Windows PowerShell remoting on other supported versions of Windows and to re-enable remoting on Windows Server 2012 if it becomes disabled.
You need to run this command only once on each computer that will receive commands. You do not need to run it on computers that only send commands. Because the configuration activates listeners, it is prudent to run it only where it is needed.
Enable and Use Remote Commands in Windows PowerShell
The Windows PowerShell remoting features are supported by the WS-Management protocol and the Windows Remote Management (WinRM) service that implements WS- Management in Windows.
In many cases, you will be able to work with remote computers in other domains. However, if the remote computer is not in a trusted domain, the remote computer might not be able to authenticate your credentials. To enable authentication, you need to add the remote computer to the list of trusted hosts for the local computer in WinRM.
