The correct order of the rule processing steps of the Distributed Firewall is as follows: Packet arrives at vfilter connection table. If matching entry in the table, process the packet. If connection table has no match, compare the packet to the rule table. If the packet matches source, destination, service, profile and applied to fields, apply the action defined. If the rule table action is allow, create an entry in the connection table and forward the packet. If the rule table action is reject or deny, take that action. This order is based on the description of how the Distributed Firewall works in the web search results1. The first step is to check if there is an existing connection entry for the packet in the vfilter connection table, which is a cache of flow entries for rules with an allow action. If there is a match, the packet is processed according to the connection entry. If there is no match, the packet is compared to the rule table, which contains all the security policy rules. The rules are evaluated from top to bottom until a match is found. The match criteria include source, destination, service, profile and applied to fields. The action defined by the matching rule is applied to the packet. The action can be allow, reject or deny. If the action is allow, a new connection entry is created for the packet and the packet is forwarded to its destination. If the action is reject or deny, the packet is dropped and an ICMP message or a TCP reset message is sent back to the source.

The correct answer is to enable the OSPF toggle and to add an Area Definition for the Tier-0 gateway

in the image. These two items are required to configure OSPF on the Tier-0 gateway, as explained in

the web search results123.

To mark your answers by clicking twice on the image, you can double-click on the toggle switch next

to OSPF to turn it on. The switch should change from gray to blue, indicating that the option is

enabled. Then, you can double-click on the Set button next to Area Definition to add an area

definition. A pop-up window should appear where you can specify the area ID and type.

1. Click the OSPF toggle to enable OSPF 2. In the Area Definition field, click Set to add an area

Load Balancing Algorithm

You specify the following parameters during the creation of a server pool:

• Name: A unique name for the server pool.

• Cloud: The cloud connector details for the NSX environment.

• VRF Context: Virtual Routing Framework (VRF) is a method to isolate traffic in a system. VRF is also

called a route domain in the load balancer community. A global VRF context is created by default.

Network administrators might create custom VRF contexts to isolate traffic between different

tenants or subsets.

• Default Server Port: New connections to servers will use this destination service port. The default

port is 80.

• Load-balancing algorithm: The selected load-balancing algorithm controls how the incoming

connections are distributed among the servers in the pool.

• Tier-1 gateway (logical router): Specify the Tier-1 gateway that you want to attach the server pool

to. This value matches the Tier-1 gateway specified for the virtual service and VIP.

The correct answer is to enable the option All LB VIP Routes on the Tier-1 gateway route

advertisement settings. This option allows the Tier-1 gateway to advertise the NSX Advanced Load

Balancer LB VIP routes to the Tier-0 gateway and other peer routers, so that the end users can reach

the production website by using the VIP address1. The other options are not relevant for this

scenario.

To mark the correct answer by clicking on the image, you can click on the toggle switch next to All LB

VIP Routes to turn it on. The switch should change from gray to blue, indicating that the option is

enabled. See the image below for reference:

The RouterLink port between a Tier-1 Gateway and a Tier-0 Gateway is automatically created when

the Tier-1 Gateway is connected to the Tier-0 Gateway through the NSX UI. This link enables routing

between the Tier-1 and Tier-0 gateways without the need for manual configuration of segments or

logical switches.

NSX Intelligence provides a visual overview of network connections within the NSX domain, allowing

administrators to see the traffic flows between different VMs and networks. It offers detailed

visibility into network traffic patterns, application dependencies, and security posture, making it a

valuable tool for monitoring and troubleshooting within NSX environments.

Tier-1 gateway: Network introspection services can be configured at the Tier-1 gateway level to

inspect and control East-West traffic between workloads.

Partner SVM (Service Virtual Machine): Network introspection is often implemented through

integration with a Partner SVM, which is a virtual machine provided by a third-party security partner

to perform deep packet inspection and other security functions.

To support Equal-Cost Multi-Path (ECMP) routing in an NSX environment, Bidirectional Forwarding

Detection (BFD) must be used for failover detection. BFD is a rapid failure detection protocol that

works with ECMP to provide fast failure detection between routers. It helps in detecting link failures

more quickly than traditional protocols, ensuring that traffic is routed through available paths as

quickly as possible.

VMware Aria Operations Networks (formerly known as vRealize Network Insight) is a tool specifically

designed for network visibility and troubleshooting. It provides insights into both virtual and physical

network infrastructures, making it ideal for identifying problems in a physical network.

The netcpa process is responsible for Local Control Plane (LCP) connectivity with the Central Control

Plane (CCP) in NSX. Using the command esxcli network ip connection list | grep netcpa,

administrators can verify the connectivity status between the LCP on the ESXi host and the CCP,

ensuring proper communication for NSX operations.
