Your network contains an Active Directory domain named contoso.com. The domain contains a
server named Server1 that runs Windows Server 2012 R2 and has the Remote Access server role
installed.
A user named User1 must connect to the network remotely. The client computer of User1 requires
Challenge Handshake Authentication Protocol (CHAP) for remote connections. CHAP is enabled on
Server1.
You need to ensure that User1 can connect to Server1 and authenticate to the domain.
What should you do from Active Directory Users and Computers?
A.
From the properties of User1, select Store password using reversible encryption.
B.
From the properties of Server1, assign the Allowed to Authenticate permission to User1.
C.
From the properties of User1, select Use Kerberos DES encryption types for this account.
D.
From the properties of Server1, select Trust this computer for delegation to any service (Kerberos
only).
Explanation:
The Store password using reversible encryption policy setting provides support for Applications that
use protocols that require the user’s password for authentication. Storing encrypted passwords in a
way that irreversible means that the encrypted passwords can be decrypted. A knowledgeable
attacker who is able to break this encryption can then log on to network resources by using the
compromised account. For this reason, never enable Store password using reversible encryption for
all users in the domain unless Application requirements outweigh the need to protect password
information. If you use the Challenge Handshake Authentication Protocol (CHAP) through remote
access or Internet Authentication Services (IAS), you must enable this policy setting. CHAP is an
authentication protocol that is used by remote access and network connections.
Digest Authentication in Internet Information Services (IIS) also requires that you enable this policy
setting. If your organization uses CHAP through remote access or IAS, or Digest Authentication in IIS,
you must configure this policy setting to Enabled. This presents a security risk when you App1y the
setting through Group Policy on a user-by-user basis because it requires the appropriate user
account object to be opened in Active Directory Users and Computers.
