A.
Set-ADFSProperties -ProxyTrustTokenLifetime 1:00:00

B.
Set-ADFSProperties -AddProxyAuthenticationRules None

C.
Set-ADFSProperties -SSOLifetime 1:00:00

D.
Set-ADFSProperties -ExtendedProtectionTokenCheck None

Explanation:
A) Sets the valid token lifetime for proxy trust tokens (in minutes). This value is used by the
federation server proxy to authenticate with its associated federation server.
B) Specifies a policy rule set that can be used to establish authorization permissions for
setting up trust proxies. The default value allows the AD FS 2.0 service user account or any
member of BUILTIN\Administrators to register a federation server proxy with the Federation
Service.
C) Specifies the duration of the single sign-on (SSO) experience for Web browser clients (in
minutes).
D) pecifies the level of extended protection for authentication supported by the federation
server. Extended Protection for Authentication helps protect against man-in-the-middle
(MITM) attacks, in which an attacker intercepts a client’s credentials and forwards them to a server.

    it’s D

    http://technet.microsoft.com/en-us/library/hh237448(v=ws.10).aspx

    Disable the Extended Protection for Authentication feature in AD FS 2.0

    Certain client browser software, such as Firefox, Chrome, and Safari, do not support the Extended Protection for Authentication capabilities that can be used across the Windows platform to protect against man-in-the-middle attacks. To prevent this type of attack from occurring over secure AD FS communications, AD FS 2.0 enforces (by default) that all communications use a channel binding token (CBT) to mitigate against this threat.
    However, if it is important that browser clients that do not support Extended Protection for Authentication must be used in your organization, you will have to adjust a feature setting in AD FS 2.0 that will disable the CBT from being used over communications, which, in turn, may leave client credentials vulnerable to man-in-the-middle attacks.

    Guys, the premium dumps are honestly a scam and are CERTAINLY not always correct. They really aren’t any different than all the other dumps out there. You still need to verify the answers are correct.

    D was my initial thought. Always double-check the answers. Aside from some answers being false, you also actually learn something that you’re supposed to know after taking the exams.
