Configuring a Distributed Firewall Rule for Domain Name-based Application Filtering

B.

On the Profile page, choose which profiles to apply the rule to.

For most servers, you should apply the rule to all three profiles, because servers are usually continually connected to a single network.

For mobile computers in domain environments, you typically need to apply firewall rules only to the Domain profile.

In VMware NSX-T Data Center, the distributed firewall provides a way to create and enforce granular firewall policies within individual virtual machines and between virtual machines. A distributed firewall rule consists of five fields: Name, Applied To, Policy, Service, and Source/Destination.

To configure a firewall rule based on the domain name of a specific application, the security administrator would need to configure the "Service" field in the distributed firewall rule.

The "Service" field refers to the network service or protocol being used by the application. When creating a firewall rule based on the domain name of an application, the administrator must identify the network service or protocol that the application is using and configure the appropriate service in the "Service" field.

For example, if the application is using HTTP or HTTPS to communicate with other systems, the security administrator would configure the appropriate service (i.e., HTTP or HTTPS) in the "Service" field of the distributed firewall rule. If the application is using a custom protocol or service, the administrator would need to identify and configure that specific service in the rule.

Therefore, the correct answer to the question is C. Service.
