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.

If Distributed Firewall Rule hit counts are not being logged, it is likely because Distributed Firewall Rule logging is not enabled. For hit counts to appear in the logs, logging must be explicitly enabled on each firewall rule where tracking is required. Without enabling logging at the rule level, no hit count information will be recorded in syslog.

Syslog Server: NSX supports forwarding logs to a centralized syslog server, which is a standard tool for centralized logging in network environments.

VMware Aria Operations for Logs (formerly known as vRealize Log Insight): This tool provides centralized log management and analytics, specifically designed to integrate with VMware environments, including NSX, for enhanced log collection, analysis, and troubleshooting.

master: The master role in NSX Manager is responsible for managing and coordinating the other NSX Manager nodes in the cluster.

policy: The policy role handles the policy-driven API and configuration, allowing administrators to define and manage network and security policies.

controller: The controller role in NSX Manager manages control plane functions and handles routing, switching, and other network state information required for NSX operations.

TIER0_DISTRIBUTED_ROUTER: The Tier-0 Distributed Router spans all transport nodes, providing distributed routing capabilities across the NSX environment at the Tier-0 level.

DISTRIBUTED_ROUTER_TIER1: Similarly, the Tier-1 Distributed Router spans all transport nodes, enabling distributed routing at the Tier-1 level, which allows routing functions to occur closer to the workload VMs across the transport nodes.
