VMware NSX 4.x Professional 2V0-41.23 Exam Questions

Answer : D

The field in a Tier-1 Gateway Firewall that would be used to allow access for a collection of trustworthy web sites isProfiles -> 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.Reference:Gateway Firewall

Answer : D

An alarm can be suppressed for a specific duration in hours.

According to the VMware NSX documentation, an alarm can be in one of the following states: Open, Acknowledged, Suppressed, or Resolved12

An alarm in a Suppressed state means that the status reporting for this alarm has been disabled by the user for a user-specified duration12

When a user moves an alarm into a Suppressed state, they are prompted to specify the duration in hours. After the specified duration passes, the alarm state reverts to Open. However, if the system determines the condition has been corrected, the alarm state changes to Resolved13

To learn more about how to manage alarm states in NSX, you can refer to the following resources:

Answer : D

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.Reference:Activate NSX Malware Prevention

Answer : C

To enable stateful active-active SNAT on a Tier-0 or Tier-1 gateway, you must configure an Interface Group for the NSX Edge uplinks. An Interface Group is a logical grouping of NSX Edge interfaces that belong to the same failure domain. A failure domain is a set of NSX Edge nodes that share the same physical network infrastructure and are subject to the same network failures.By configuring an Interface Group, you can ensure that the stateful services are distributed across different failure domains and can recover from network failures1

Answer : B

Route-based VPN is a VPN type that uses Virtual Tunnel interfaces (VTI) to establish IPSec tunnels between an NSX Edge node and remote sites2. A VTI is a logical interface that is assigned an IP address and is associated with a physical or virtual interface.The VTI acts as an end point of the IPSec tunnel and routes traffic between the NSX Edge node and the remote site2. Route & SSL based VPNs, Policy & Route based VPNs, and SSL-based VPN are not VPN types that use VTI.Reference:Virtual Private Network (VPN)

Answer : B

According to the VMware Knowledge Base article1, the CLI command to set the log level of the NSX Manager to debug mode is set service manager logging-level debug.This command can be used when the NSX UI is inaccessible or when troubleshooting issues with the NSX Manager1. The other commands are incorrect because they either use a wrong syntax or a wrong service name.The NSX Manager service name is manager, not nsx-manager2.The log level parameter is logging-level, not log-level3.
