Which of the following can be used to define a subnet that will be permanently associated with a security group?

The correct choice involves using IP-SGT static mappings to define a subnet that is permanently associated with a security group. In Cisco Identity Services Engine (ISE), IP-SGT static mappings allow administrators to manually associate specific IP addresses or subnets with Security Group Tags (SGTs). This association is critical for implementing access control policies based on the SGTs that represent various security levels or group identities within the network.

By utilizing IP-SGT static mappings, a network administrator can ensure that any device within the specified subnet inherits the same security policies associated with the corresponding SGT. This approach is particularly useful for ensuring consistent policy application and simplifies management, as the association remains in place irrespective of dynamic changes in device endpoints or network conditions.

In contrast, dynamic classification refers to methods where devices are classified based on their behaviors or attributes during their connection to the network, rather than being statically mapped to a subnet. As for SGT Transport, it pertains to the methods of carrying SGT information within various types of network traffic but does not define permanent subnet associations. SGACLs, or Security Group Access Control Lists, are involved in defining policies applied to security groups but do not establish the associations between subnets and security groups directly.

Therefore, IP-SGT
