VMware 5V0-41.21 - VMware NSX-T Data Center 3.1 Security

For further reading, see the VMware NSX-T Data Center Administration Guide (https://pubs.vmware.com/NSX-T-Data-Center/index.html#com.vmware.nsxt.admin.doc/GUID-BEDA8D9F-ACBC-42B1-B7F5-FEEF0E0D899C.html)  for more information on configuring dynamic groups.

The two statements that are true about NSX Intelligence are that it assists to build service insertion with Partner SVM and that it supports planning of NSX-T Edge Firewall rules and policy. NSX Intelligence can be used in conjunction with vRealize Network Insight to provide visibility and insights into the network, but it cannot be used to visualize the physical infrastructure. Additionally, while it can help to plan firewall rules and policy, it does not support planning of distributed firewall rules and policy.

When deploying an NSX Edge Virtual Machine through an ISO image, the virtual network interface card (vNIC) type that must be selected is VMXNET3 in order to allow participation in overlay and VLAN transport zones. VMXNET3 is a high-performance and feature-rich paravirtualized NIC that provides a significant performance boost over other vNIC types, as well as support for both overlay and VLAN transport zones.

For more information on deploying an NSX Edge Virtual Machine through an ISO image, 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-deploy-config/GUID-A782558B-A72B-4848-B6DB-7A8A9E71FFD6.html

Zero-Trust Networks is a security concept that assumes that all devices, users, and networks are untrusted until they can be verified. This means that all network-connected devices must be verified for their identity and integrity before they are granted access to resources. This is done continually, meaning that devices are verified every time they try to access a resource, rather than being trusted permanently.

C. Network connected devices should only be trusted if their identity and integrity can be verified continually. This is the main concept of Zero-Trust Networks, every device that wants to access the network should be authenticated and verified its identity and integrity.

 In order to block the gambling websites, the security administrator needs to update the URL Analysis Attributes in NSX-T. URL Analysis Attributes are used to control access to web content, and can be configured to deny access to certain web destinations based on domain names or categories.

For more information on URL Analysis Attributes and how to configure them, please refer to the NSX-T Data Center documentation [1]: https://docs.vmware.com/en/VMware-NSX-T-Data-Center/3.0/nsx-t-3.0-url-profile/GUID-F8BA3F3F-4A27-4B4F-8D2A-A013F68E1619.html

This command allows you to display the current firewall ruleset configuration on an ESXi host. It will show the ruleset names, whether they are enabled or disabled, and the services and ports that the ruleset applies to.

For example, you can use the command "esxcli network firewall ruleset list" to list all the firewall rulesets on the host.

You can also use the command "esxcli network firewall ruleset rule list -r " to display detailed information of the specific ruleset, where is the name of the ruleset you want to display.

It's important to note that you need to have access to the ESXi host's command-line interface (CLI) and have appropriate permissions to run this command.
