Check for Domain Computer Authentication in Cisco Identity Services Engine

C.

Option B, Active Directory Attributes, is the correct answer to the question. Cisco Identity Services Engine (ISE) is a policy server that provides secure access to network resources. ISE integrates with Active Directory (AD) to authenticate users and machines. AD is a directory service provided by Microsoft that stores information about network resources such as users, computers, and groups.

Active Directory attributes are used to check if the user authentication comes from a domain computer. ISE can query AD for attributes such as the computer name, domain, and operating system. The computer name and domain are compared to the expected values to determine if the authentication request is coming from a domain computer.

Option A, an identity source sequence, is used to specify the order in which ISE should query identity sources for user authentication. It is not directly related to validating the computer domain membership.

Option C, Machine Access Restriction, is used to restrict access to the network based on machine attributes such as MAC address or hostname. It is not directly related to validating the computer domain membership.

Option D, Group Policy Objects, are used to manage user and computer settings in an Active Directory environment. Group Policy Objects can be used to enforce security policies on domain-joined computers, but they are not used to validate computer domain membership in ISE.

Option E, It is not possible to validate the computer domain membership through IS, is not correct. ISE can validate computer domain membership through Active Directory attributes.
