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

In Non-Preemptive failover policy, once a failover occurs and a new Active node is designated, the original failed node will not automatically become the Active node upon recovery. This setting ensures that the failover does not revert to the original node after it comes back online, maintaining the stability of the network by keeping the current Active node as is.

For a 3-node NSX Manager cluster, all nodes must be within the same subnet to ensure proper communication and functionality between them.

A compute manager must be configured before adding nodes to the cluster, as it provides the necessary integration between the NSX Manager and the underlying virtualization infrastructure (such as vSphere or vCenter).

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.

When logging is enabled for a firewall rule in NSX, the logs are stored on the ESXi transport node in the /var/log/vmware/nsx/firewall.log file. This file contains information about firewall rule hits and is useful for monitoring and troubleshooting firewall activity on the transport node.

The show log manager follow command is used on the NSX Manager to view the syslog in real-time. This command displays ongoing log entries, allowing administrators to monitor syslog messages as they are generated, which is helpful for troubleshooting and real-time analysis.

The field in a Tier-1 Gateway Firewall that would be used to allow access for a collection of trustworthy web sites is Profiles -> L7 Access Profile. This field allows the user to create a Layer 7 access profile that defines a list of allowed or blocked URLs based on categories, reputation, or custom entries1. The user can then apply the L7 access profile to a firewall rule to control the traffic based on the URL filtering criteria1. The other options are incorrect because they are not related to URL filtering. The Source field specifies the source IP address or group of the firewall rule1. The Destination field specifies the destination IP address or group of the firewall rule1. The Profiles -> Context Profiles field allows the user to create a context profile that defines a list of application signatures or attributes that can be used to identify and classify network traffic1. References: Gateway Firewall

According to the VMware NSX Documentation, these are two of the use cases for Distributed Intrusion Detection, which is a feature of NSX Network Detection and Response:

Quarantine workloads based on vulnerabilities: You can use Distributed Intrusion Detection to detect vulnerabilities in your workloads and apply quarantine actions to isolate them from the network until they are remediated.

Identify security vulnerabilities in the workloads: You can use Distributed Intrusion Detection to scan your workloads for known vulnerabilities and generate reports that show the severity, impact, and remediation steps for each vulnerability.

When a stateful service (such as NAT or firewall) is enabled for the first time on a Tier-0 Gateway, the Service Router (SR) is instantiated on the NSX Edge node and automatically connected with the Distributed Router (DR). This connection enables the Tier-0 Gateway to handle stateful services by routing traffic through the SR, which manages stateful packet processing, while the DR provides distributed routing functionality.

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.

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.

The set ntp-server command is used on NSX Manager and NSX Edge to configure the NTP (Network Time Protocol) settings. This command allows administrators to specify the NTP server, ensuring that the NSX components synchronize their time accurately with the designated time server.
