5V0-41.21 VMware NSX-T Data Center 3.1 Security Questions and Answers

The NSX administrator has enabled logging for the distributed firewall rule, and the logs are stored in the /var/log/dfwpktlogs.log file on the ESXi host. This log file stores the packet logs for the distributed firewall rules, and the logs can be used for auditing and troubleshooting the distributed firewall.

NSX-T Endpoint Protection provides agentless antivirus protection for virtual machines running on VMware ESXi hosts. It uses the VMware vShield Endpoint API to scan the virtual machines without requiring the installation of antivirus agents. The service is integrated with third-party antivirus solutions, such as McAfee and Symantec, to provide real-time protection against malware and other threats.

For more information on NSX-T Endpoint Protection, please refer to the NSX-T Data Center documentation: https://docs.vmware.com/en/VMware-NSX-T-Data-Center/3.0/nsx-t-3.0-endpoint-protection/GUID-25C22F02-4B30-47D4-8F0C-3BC9F9C3AFD3.html

The component in a transport node that receives the firewall configuration from the central control plane is the NSX-MPA (Management Plane Agent). The NSX-MPA runs on each transport node and is responsible for connecting to the NSX-T central control plane and receiving the configuration for the transport node. It is also responsible for pushing the configuration down to the other components on the transport node, such as the NSX-Proxy, NSX-Appl-Proxy, and NSX-CCP.

NSX Gateway Firewall is a distributed firewall that provides security for east-west traffic within a virtual environment.

B. Firewall rules in Pre Rule category are applied to all gateways. This category contains system-defined rules that are always applied first to all gateways and cannot be modified. These rules include the default deny all rule and others that control basic connectivity.

D. Security Groups can be used in Applied-To column. Security groups allow you to group together VMs that have similar security requirements and then apply firewall policies to those groups. This way you can apply the same security rules to multiple VMs at once, instead of configuring the rules on each individual VM.
