NAT64 is supported on both Tier-0 and Tier-1 gateways, allowing for IPv6-to-IPv4 address translation at different gateway levels within NSX.

NAT64 requires the Tier-1 gateway to be configured in active-standby mode, as this configuration ensures stateful translation and consistency for IPv6-to-IPv4 traffic handling.

Traceflow: This tool helps in troubleshooting network issues by injecting synthetic packets into the network and observing their path. It allows administrators to trace the packet flow across various network segments, making it easier to identify points of packet loss.

Packet Capture: This tool enables detailed inspection of traffic by capturing packets at specific points in the network. It allows administrators to analyze packet headers and payloads to determine if packet loss is occurring and to identify possible causes.

The ifconfig command is used to display the network configuration of interfaces, including the Tunnel Endpoint (TEP) IP on a bare metal transport node. This command provides details about IP addresses, subnet masks, and other network settings for each interface on the node.

Area ID: Both routers must belong to the same OSPF area for a neighbor relationship to form.

MTU of the Uplink: Mismatched MTU settings can prevent the OSPF adjacency from forming, as OSPF packets may be dropped if they exceed the MTU size.

Subnet mask: Both routers must have the same subnet mask on the interface where OSPF is configured to establish a neighbor relationship.

The answer is C. Group all by means of tags membership.

Tags are metadata that can be applied to physical servers, virtual machines, logical ports, and logical segments in NSX. Tags can be used for dynamic security group membership, which allows for granular and flexible enforcement of security policies based on various criteria1

In the scenario, the company is deploying NSX micro-segmentation to secure a simple application composed of web, app, and database tiers. The naming convention will be:

WKS-WEB-SRV-XXX

WKY-APP-SRR-XXX

WKI-DB-SRR-XXX

The optimal way to group them to enforce security policies from NSX is to use tags membership. For example, the company can create three tags: Web, App, and DB, and assign them to the corresponding VMs based on their names. Then, the company can create three security groups: Web-SG, App-SG, and DB-SG, and use the tags as the membership criteria. Finally, the company can create and apply security policies to the security groups based on the desired rules and actions2

Using tags membership has several advantages over the other options:

It is more scalable and dynamic than using Edge as a firewall between tiers. Edge firewall is a centralized solution that can create bottlenecks and performance issues when handling large amounts of traffic3

It is more simple and efficient than doing a service insertion to accomplish the task. Service insertion is a feature that allows for integrating third-party services with NSX, such as antivirus or intrusion prevention systems. Service insertion is not necessary for basic micro-segmentation and can introduce additional complexity and overhead.

It is more flexible and granular than creating an Ethernet based security policy. Ethernet based security policy is a type of policy that uses MAC addresses as the source or destination criteria. Ethernet based security policy is limited by the scope of layer 2 domains and does not support logical constructs such as segments or groups.

To learn more about tags membership and how to use it for micro-segmentation in NSX, you can refer to the following resources:

NSX Intelligence is a distributed analytics solution within the VMware NSX Portfolio that provides visibility and dynamic security policy enforcement in NSX environments. It enables detailed traffic analysis, identifies security threats, and helps in the automated creation and enforcement of security policies based on observed network traffic patterns and behaviors.

For a VMware Kubernetes deployment in an NSX environment, the minimum recommended MTU size for the UPLINK profile is 1700. This allows sufficient space for the additional overhead introduced by encapsulation protocols, such as Geneve, used in NSX-T Data Center, ensuring optimal performance and avoiding fragmentation.

Auditor: Allows users to view settings and logs without making changes.

Full access: Provides complete control over all NSX settings and configurations.

None: No permissions are granted, restricting access completely.

Read: Allows users to view configurations and settings without editing capabilities.

A group is a logical construct that represents a collection of objects in NSX, such as segments, segment ports, virtual machines, IP addresses, MAC addresses, tags, or security policies. A group can be used to define dynamic membership criteria based on various attributes or filters. A group can also be used as the scope of a distributed firewall rule, which means that the rule will apply to all the traffic that matches the group membership criteria32
