These are examples of which of the following?
A. Multifactor authentication
B. Single factor authentication
C. Separation of duties

A. Trusted OS
B. Mandatory access control
C. Separation of duties
D. Single sign-on
Answer: D

A. Multi-factor authentication
B. Smart card access

D. Single Sign-On
Answer: D
Explanation:
Single sign-on means that once a user (or other subject) is authenticated into a realm, re- authentication is not required for access to resources on any realm entity. Single sign-on is able to internally translate and store credentials for the various mechanisms, from the credential used for original authentication.
QUESTION 637

A. Dual-factor authentication
B. Multifactor authentication
C. Single factor authentication
D. Biometric authentication
Answer: C
Explanation:
Multi-factor authentication (MFA) is a method of computer access control which a user can pass by successfully presenting authentication factors from at least two of the three categories:
knowledge factors (“things only the user knows”), such as passwords possession factors (“things only the user has”), such as ATM cards inherence factors (“things only the user is”), such as biometrics
In this question a username, password, and a four-digit security pin knowledge are all knowledge factors (something the user knows). Therefore, this is single-factor authentication.
QUESTION 638

A. Attributes based
B. Implicit deny
C. Role based

A. A security group
B. A group policy
C. Key escrow

QUESTION 647
A network inventory discovery application requires non-privileged access to all hosts on a network for inventory of installed applications. A service account is created by the network inventory discovery application for accessing all hosts. Which of the following is the MOST efficient method for granting the account non-privileged access to the hosts?
A. Implement Group Policy to add the account to the users group on the hosts
B. Add the account to the Domain Administrator group
C. Add the account to the Users group on the hosts
D. Implement Group Policy to add the account to the Power Users group on the hosts.
Answer: A
Explanation:
Group Policy is an infrastructure that allows you to implement specific configurations for users and computers. Group Policy settings are contained in Group Policy objects (GPOs), which are linked to the following Active Directory directory service containers: sites, domains, or organizational units (OUs). This means that if the GPO is linked to the domain, all Users groups in the domain will include the service account.
QUESTION 648
A group policy requires users in an organization to use strong passwords that must be changed every 15 days. Joe and Ann were hired 16 days ago. When Joe logs into the network, he is prompted to change his password; when Ann logs into the network, she is not prompted to change her password. Which of the following BEST explains why Ann is not required to change her password?
A. Ann’s user account has administrator privileges.
B. Joe’s user account was not added to the group policy.
C. Ann’s user account was not added to the group policy.
D. Joe’s user account was inadvertently disabled and must be re-created.
Answer: C
Explanation:
Group policy is used to manage Windows systems in a Windows network domain environment by means of a Group Policy Object (GPO). GPO’s include a number of settings related to credentials, which includes password expiration. Because Anne was not prompted to change her password, it could only mean that her user account was not added to the group policy.
QUESTION 649
An auditing team has found that passwords do not meet best business practices.
Which of the following will MOST increase the security of the passwords? (Select TWO).

Passwords should have the strength to avoid discovery through attack, but it should also be easy enough for the user to remember. The length and complexity of a password combined are vital factors in defining a password’s strength.
QUESTION 650
Which of the following passwords is the LEAST complex?
A. MyTrain!45
B. [email protected]!!
C. [email protected]
D. [email protected]#8
Answer: B

Password policies often enforce a minimum of three out of four standard character types, which includes uppercase and lowercase letters, numbers, and symbols. Although this option includes three of the four character types, it does not include numbers, which makes it less complex than the other options.
