2V0-41.24 VMware NSX 4.X Professional V2 Free Practice Exam Questions (2025 Updated)

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.

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.

In NSX and VMware environments, an alarm in a suppressed state can typically be set to remain suppressed for a specific duration measured in hours. This allows administrators to temporarily ignore the alarm for a set period while working on a resolution without continuous alerts.

Distributed Firewall on VDS is a feature of NSX-T Data Center that allows users to install Distributed Security for vSphere Distributed Switch (VDS) without the need to deploy an NSX Virtual Distributed Switch (N-VDS). This feature provides NSX security capabilities such as Distributed Firewall (DFW), Distributed IDS/IPS, Identity Firewall, L7 App ID, FQDN Filtering, NSX Intelligence, and NSX Malware Prevention. To enable this feature, the following requirements must be met in the environment:

The NSX version must be 3.2 and later1. This is the minimum version that supports Distributed Security for VDS.

The VDS version must be 6.6.0 and later1. This is the minimum version that supports the NSX host preparation operation that activates the DFW with the default rule set to allow.

Using a Transport Node Profile allows the administrator to apply configuration changes, such as specifying an NTP server, across multiple Edge Transport Nodes efficiently. This method is scalable and avoids the need for manual configuration on each individual node. Once the Transport Node Profile is updated, the configuration can be pushed to all associated nodes.

AS-Path Prepend: This attribute allows you to prepend one or more AS numbers to the AS path of a route, making it appear longer and less preferable to other BGP routers. You can use this attribute to manipulate the inbound traffic from your BGP peers by advertising a longer AS path for some routes and a shorter AS path for others.

MED: This attribute stands for Multi-Exit Discriminator and allows you to specify a preference value for a route among multiple exit points from an AS. You can use this attribute to manipulate the outbound traffic to your BGP peers by advertising a lower MED value for some routes and a higher MED value for others.

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.

Display how the different NSX components are interconnected.

Network Topology in NSX provides a visual representation of how different NSX components (like Edge nodes, Logical Routers, and other NSX components) are interconnected.

Display the VMs connected to Segments.

It also allows you to see which VMs are connected to specific segments (logical switches).

Display how the Physical components are interconnected.

The Network Topology view includes information about how physical network components are connected, providing a comprehensive overview of both the virtual and physical networking infrastructure.

BGP Neighbors: This parameter is essential for establishing BGP sessions with other routers. Configuring BGP neighbors allows VRF Lite gateways to exchange routing information with adjacent BGP-enabled devices.

Local AS: The Local Autonomous System (AS) number can be set for the VRF Lite gateway, which is necessary for BGP operations within a specific routing domain.

The NSX Edge supports L2 VPN (Layer 2 VPN) functionality, which allows it to connect different Layer 2 networks over an IP transport.

Third-party hardware VPN devices can also be used as L2 VPN clients, providing connectivity between different Layer 2 networks through an external device.

The Tier-0 gateway is the valid insertion point for North-South network introspection in an NSX environment. North-South traffic refers to traffic entering or leaving the data center, and the Tier-0 gateway is responsible for routing this traffic between the NSX environment and external networks. Placing network introspection at the Tier-0 gateway allows for inspection and security policies to be applied to traffic as it moves in and out of the data center.

Core Files should be excluded when collecting support bundles through NSX Manager because they may contain sensitive information, such as memory dumps that could reveal sensitive data from processes at the time of an issue. Excluding core files helps ensure that potentially sensitive data is not unintentionally shared.

VMware recommends deploying a virtual NSX Edge Node using an ISO in either automated or interactive mode. This method provides flexibility and ensures that the NSX Edge node is deployed properly with all the necessary configurations. Using an ISO allows for a more streamlined and controlled deployment process, especially in larger environments.

Gateway DHCP: NSX supports DHCP services configured on the gateway, allowing it to provide IP addresses to clients within the network.

Segment DHCP: NSX can provide DHCP services at the segment level, where DHCP is configured directly on a network segment to assign IP addresses to connected clients.

DHCP Relay: NSX supports DHCP Relay, which allows forwarding of DHCP requests to an external DHCP server for IP address assignment.

In NSX, BGP is the only supported dynamic routing protocol on a Tier-1 Gateway. OSPF is not supported at the Tier-1 level; it is only available on Tier-0 Gateways. This limitation means that for dynamic routing on a Tier-1 Gateway, administrators can configure BGP to exchange routing information with connected Tier-0 Gateways.

Both TCP and UDP are commonly used protocols for transferring log messages in syslog configurations. TCP is preferred when reliability is needed, while UDP is used for faster, connectionless transmission.

TLS can be used to secure the log messages being sent over TCP, ensuring encrypted transmission to the remote log server.

Virtual Tunnel Interfaces (VTI) are used in route-based VPNs. In this type of VPN, the tunnel is treated like a regular interface on the router. This allows for the configuration of routing protocols and the application of routing decisions to the traffic flowing through the VPN tunnel. VTIs simplify the management of routing and make it more flexible in VPN scenarios.

NSX Federation allows consistent policy configuration and enforcement across multiple NSX instances or environments. It provides a unified framework to manage security and networking policies across different NSX deployments, enabling centralized control and consistent application of policies across multiple sites or data centers.
