To activate Malware Prevention on the NSX Application Platform, the steps are:
In the NSX Manager UI, select System and in the Configuration section, select NSX Application Platform.
Navigate to the Features section, locate the NSX Malware Prevention feature card, and click Activate or anywhere in the card.
In the NSX Malware Prevention activation window, select one of the available cloud regions from which you can access the NSX Advanced Threat Prevention cloud service.
Click Run Prechecks. This precheck process can take some time as the system validates that the minimum license requirement is met and that it is eligible for use with the NSX Advanced Threat Prevention cloud service. The system also validates that the selected cloud region is reachable.
Click Activate. This step can take some time1. Therefore, the correct answer is D: The other options are incorrect because they involve activating or deploying NSX Network Detection and Response, which is a different feature from Malware Prevention.

An IDS signature contains data used to identify an attacker's attempt to exploit a known vulnerability in both the operating system and applications.
IDS/IPS Profiles are used to group signatures, which can then be applied to select applications and traffic.

NSX supports two types of authentication, authorization, and accounting (AAA) systems when integrating with VMware Identity Manager: RSA SecurID and LDAP and OpenLDAP based on Active Directory (AD). RSA SecurID is a two-factor authentication system that uses a token-based approach to verify the identity of users. LDAP and OpenLDAP based on AD are directory services that store and manage user information and credentials. Both systems can be used to provide centralized authentication for users who want to access applications in an NSX environment.
https://blogs.vmware.com/networkvirtualization/2017/11/remote-user-authentication-and-rbac-with-nsx- t.html The integration of VMware Identity Manager with NSX provides the following benefits related to user authentication:
* Support for extensive authentication, authorization, and accounting (AAA) systems, including:
- RADIUS
- Smart cards and common access cards
- RSA SecureID
- LDAP and OpenLDAP based on Active Directory (AD)
* Enterprise SSO:
- Common authentication platform across multiple VMware solutions
- Seamless SSO experience
NSX has its own native LDAP and Active Directory integration, but VMware Identity Manager also offers this capability

It supports a 4-byte autonomous system number: BGP on a Tier-0 Gateway supports 4-byte AS (Autonomous System) numbers, which are necessary for larger routing domains.
Can be used as an Exterior Gateway Protocol: BGP is commonly used as an Exterior Gateway Protocol to establish routing between different autonomous systems (AS).
BGP is enabled by default: On a Tier-0 Gateway, BGP is typically enabled by default, allowing administrators to configure it for external routing.
