2V0-41.23 VMware NSX 4.x Professional Free Practice Exam Questions (2025 Updated)

To configure a firewall rule based on the domain name of a specific application, the administrator needs to use the Profile field in a distributed firewall rule. The Profile field allows the administrator to select a context profile that contains one or more attributes for filtering traffic. One of the attributes that can be used is Domain (FQDN) Name, which specifies the fully qualified domain name of the application. For example, if the administrator wants to filter traffic to *.office365.com, they can create a context profile with the Domain (FQDN) Name attribute set to *.office365.com and use it in the Profile field of the firewall rule.

The sequence of commands that could be used to check the BGP connection status between the Tier-O Gateway and the upstream physical router on NSX Edge node is get gateways, vrf , get bgp neighbor. These commands can be executed on the NSX Edge node CLI after logging in as admin6. The first command, get gateways, displays the list of logical routers (gateways) configured on the Edge node, along with their IDs and VRF numbers7. The second command, vrf , switches to the VRF context of the desired Tier-O Gateway, where is the VRF number obtained from the previous command7. The third command, get bgp neighbor, displays the BGP neighbor summary for the selected VRF, including the neighbor IP address, AS number, state, uptime, and prefixes received8. The other options are incorrect because they either use invalid or incomplete commands or do not switch to the correct VRF context. References: NSX-T Command-Line Interface Reference, NSX Edge Node CLI Commands, Troubleshooting BGP on NSX-T Edge Nodes

According to the VMware NSX Documentation1, NSX-T Data Center supports the following types of DHCP configuration on a segment:

Local DHCP server: This option creates a local DHCP server that has an IP address on the segment and provides dynamic IP assignment service only to the VMs that are attached to the segment.

Gateway DHCP server: This option is attached to a tier-0 or tier-1 gateway and provides DHCP service to the networks (overlay segments) that are directly connected to the gateway and configured to use a gateway DHCP server.

DHCP Relay: This option relays the DHCP client requests to the external DHCP servers that can be in any subnet, outside the SDDC, or in the physical network.

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 .

According to the web search results, the command that is used to verify the Local Control Plane (LCP) connectivity with Central Control Plane (CCP) on ESXi is get control-cluster status. This command displays the status of the LCP and CCP components on the ESXi host, such as the LCP agent, CCP client, CCP server, and CCP connection. It also shows the IP address and port number of the CCP server that the LCP agent is connected to. If the LCP agent or CCP client are not running or not connected, it means that there is a problem with the LCP connectivity .

When deploying an NSX Edge Transport Node, two valid IP address assignment options that should be specified for the TEP IP addresses are Use an IP Pool and Use a Static IP List. These options allow the user to assign TEP IP addresses from a predefined range of IP addresses or a manually entered list of IP addresses, respectively345. The other options are incorrect because they are not supported methods for assigning TEP IP addresses. There is no option to use a DHCP server, RADIUS, or BootP for TEP IP address assignment in NSX-T345. References: NSX-T Edge TEP networking options, Multi-TEP High Availability, Create an IP Pool for Host Tunnel Endpoint IP Addresses

To generate the support bundle logs on the NSX Manager via API, the NSX administrator needs to use the POST method with the URL https://nsxmgr_ip/api/1.0/appliance-management/techsupportlogs/NSX, where nsxmgr_ip is the IP address of the NSX Manager 1. This will create a tech support bundle file with a name like vcpnv.tgz. To download the generated tech support bundle file via CLI, the NSX administrator needs to use the get support-bundle file vcpnv.tgz command on the NSX Manager1. The other commands are incorrect because they either do not generate or download the support bundle logs, or they are not related to the NSX Manager.

According to the VMware NSX Documentation1, a segment is mapped to a unique Geneve segment that is distributed across the ESXi hosts in a transport zone. The Geneve segment uses a virtual network identifier (VNI) as an overlay network identifier. The VNI ID can be used to identify overlay segments in an NSX environment if troubleshooting is required.

To activate Malware Prevention on the NSX Application Platform, the steps are:

In the NSX Manager UI, select System and in the Configuration section, select NSX Application Platform.

Navigate to the Features section, locate the NSX Malware Prevention feature card, and click Activate or anywhere in the card.

In the NSX Malware Prevention activation window, select one of the available cloud regions from which you can access the NSX Advanced Threat Prevention cloud service.

Click Run Prechecks. This precheck process can take some time as the system validates that the minimum license requirement is met and that it is eligible for use with the NSX Advanced Threat Prevention cloud service. The system also validates that the selected cloud region is reachable.

Click Activate. This step can take some time1. Therefore, the correct answer is D. The other options are incorrect because they involve activating or deploying NSX Network Detection and Response, which is a different feature from Malware Prevention. References: Activate NSX Malware Prevention

Route Aggregation and and D) BGP neighbours are available when configuring BGP in a VRF. "Route distribution" does not exist, what you can do is a "Route Re-Distribution" via BGP. https://docs.vmware.com/en/VMware-NSX/4.1/administration/GUID-4CB5796A-1CED-4F0E-ADE0-72BF7B3F762C.html

The correct answers are A. Files and anti-malware (file) events from the NSX Edge nodes and the Security Analyzer, D. IDS/IPS events from the ESXi hosts and NSX Edge nodes, and E. Suspicious Traffic Detection events from NSX Intelligence. According to the VMware NSX Documentation3, these are the three data collection sources that are used by NSX Network Detection and Response to create correlations/intrusion campaigns.

The other options are incorrect or not supported by NSX Network Detection and Response. East-West anti-malware events from the ESXi hosts are not collected by NSX Network Detection and Response3. Distributed Firewall flow data from the ESXi hosts are not used for correlation/intrusion campaigns by NSX Network Detection and Response3.

According to the VMware NSX Documentation, this is the NSX feature that can be leveraged to achieve consistent policy configuration and simplicity across sites:

NSX Federation: This feature allows you to create and manage a global network infrastructure that spans across multiple sites using a single pane of glass. You can use this feature to synchronize policies, segments, gateways, firewalls, VPNs, load balancers, and other network services across sites.

The log for a firewall rule on an ESXi transport node is stored in the /var/log/dfwpktlogs.log file. This file contains information about the packets that match or do not match the firewall rules, such as the source and destination IP addresses, ports, protocols, actions, and rule IDs. The log file can be viewed using the esxcli network firewall get command or the vSphere Client.

According to the web search results, network segmentation is a feature of NSX that improves the security of today’s modern workloads by preventing lateral movement. Lateral movement is a technique used by attackers to move from one compromised system to another within a network, exploiting vulnerabilities or credentials . Network segmentation prevents lateral movement by dividing a network into smaller segments or zones, each with its own security policies and controls. This way, if one segment is compromised, the attacker cannot access other segments or resources . NSX enables network segmentation by using micro-segmentation, which applies granular firewall rules at the virtual machine level, regardless of the physical network topology .

According to the VMware NSX Documentation, these are two NAT rule types that are supported for a tier-0 gateway configured in active-standby high availability mode. NAT stands for Network Address Translation and is a feature that allows you to modify the source or destination IP address of a packet as it passes through a gateway.

Destination NAT: This rule type allows you to change the destination IP address of a packet from an external IP address to an internal IP address. You can use this rule type to provide access to your internal servers from external networks using public IP addresses.

Source NAT: This rule type allows you to change the source IP address of a packet from an internal IP address to an external IP address. You can use this rule type to provide access to external networks from your internal servers using public IP addresses.
