Explanation
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. References: Activate NSX Malware Prevention
