Set-NetIPv6Protocol [-DhcpMediaSense<DhcpMediaSense>]
Modifies the DHCPMediaSense property. This parameter value provides a mechanism for the network adapter to notify the protocol stack of media connect and disconnect events.
These events trigger the DHCP client to take some action, such as attempting to renew a DHCP lease or removing routes related to a disconnected network.
One application of Media Sense enables the network parameters on the notebook computer of a roaming user to automatically and transparently update without rebooting when the user moves from one location to another.
The acceptable values for this parameter are:
- Enabled: DhcpMediaSense set to Enabled.
- Disabled: DhcpMediaSense is set to Disabled.
The default value is Enabled.

QUESTION 48
A company has client computers that run Windows 8.
The company implements the following security requirements:
- All client computers must use two-factor authentication.
- At least one authentication method must include exactly four characters or gestures.
You need to choose authentication methods that comply with the security requirements.
Which two authentication methods should you choose? (Each correct answer presents part of the solution. Choose two.)

A.    PIN
B.    Biometric authentication
C.    Picture password
D.    Microsoft account

Answer: AB
Explanation:
Something the user knows: PIN (4 digits)
One might be tempted to think the photo for the picture password is something the User has.
But it is something the User knows, too:
He knows how to draw the gestures (maximum 3 gestures supported with picture password),
and it is no physical object (like a token, smart card ...)
The MS Account is too something the user knows.
So the answer must be Biometric authentication.
Two-factor authentication requires the use of two of the three authentication factors:
Something the user knows (e.g., password, PIN);
Something the user has (physical Object) (e.g., ATM card, smart card);
and Something the user is (e.g., biometric characteristic, such as a fingerprint).
The factors are identified in the standards and regulations for access to U.S. Federal Government systems.

QUESTION 49
A company has client computers that run Windows 8.
The company implements the following security requirements:
- All client computers must use two-factor authentication.
- At least one authentication method must include more than four characters or gestures.
You need to choose authentication methods that comply with the security requirements.
Which two authentication methods should you choose? (Each correct answer presents part of the solution. Choose two.)

A.    PIN
B.    Biometric authentication
C.    Picture Password
D.    Microsoft Account

Answer: BD
Explanation:
More than 4 characters are of course supported with the Microsoft Account.
It is something the user knows. The picture password would be another thing the user knows (gestures). So there's only MS Account and Biometric authentication left.
Two-factor authentication requires the use of two of the three authentication factors:
Something the user knows (e.g., password, PIN);
Something the user has (physical Object) (e.g., ATM card, smart card);
and Something the user is (e.g., biometric characteristic, such as a fingerprint).
The factors are identified in the standards and regulations for access to U.S. Federal Government systems.
