Free Practice Questions for VMware 2V0-41.23 Exam

According to the VMware NSX CLI Reference Guide, this CLI command shows the syslog messages on the NSX Manager node. You can use this command to view the system logs for troubleshooting or monitoring purposes.

The other options are either incorrect or not available for this task. get log-file auth.log is a CLI command that shows the authentication logs on the NSX Manager node, not the syslog messages. /var/log/syslog/syslog.log is not a CLI command, but a file path that may contain syslog messages on some Linux systems, but not on the NSX Manager node. show log manager follow is not a valid CLI command, as there is no show log command or manager option in the NSX CLI.

## NSX Cli command

get log-file

get log-file follow

# Below are commonly used log files, there are many more log files

get log-file [follow]

# use [follow] to continuing monitor

Example: get log-file syslog follow

get log-file syslog

A node profile is a configuration template that can be applied to multiple NSX Edge nodes or transport nodes at once. A node profile can include settings such as NTP server, DNS server, syslog server, and so on1. By using a node profile, an administrator can efficiently configure or update the network settings of multiple NSX Edge nodes or transport nodes in a single operation2. The other options are incorrect because they are either not efficient or not supported. Using the CLI on each Edge node would require manual and repetitive commands for each node, which is not efficient. Using a Transport Node Profile would not work, because a Transport Node Profile is used to configure the NSX-T Data Center components on a transport node, such as the transport zone, the N-VDS, and the uplink profiles3. Using a PowerCLI script might work, but it would require writing and testing a custom script, which is not as efficient as using a built-in feature like a node profile.

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.

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:

VMware NSX Documentation: Managing Alarm States 1

VMware NSX Documentation: View Alarm Information 2

VMware NSX Intelligence Documentation: Manage NSX Intelligence Alarm States 3

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.

According to the web search results, error code 1001 is related to a time synchronization issue between the ESXi host and the NSX Manager. This can cause problems when configuring a time-based firewall rule, which requires the ESXi host and the NSX Manager to have the same time zone and NTP server settings . To resolve this error, you need to restart the NTP service on the ESXi host to synchronize the time with the NSX Manager. You can use the following command to restart the NTP service on the ESXi host:

/etc/init.d/ntpd restart

The other options are not valid solutions for this error. Reinstalling the NSX VIBs on the ESXi host will not fix the time synchronization issue. Changing the time zone on the ESXi host may cause more discrepancies with the NSX Manager. Reconfiguring the ESXi host with a local NTP server may not be compatible with the NSX Manager’s NTP server.

The four types of role-based access control (RBAC) permissions are Read, None, Full access, and Execute1. Read permission allows the user to view the configuration and status of the system. None permission denies any access to the system. Full access permission grants all permissions including Create, Read, Update, and Delete (CRUD). Execute permission includes Read and Update permissions1. Auditor, Enterprise Admin, and Network Admin are not types of permissions, but types of roles that have different sets of permissions. References: NSX Features

There are four types of permissions. Included in the list are the abbreviations for the permissions that are used in the Roles and Permissions and Roles and Permissions for Manager Mode tables.

Full access (FA) - All permissions including Create, Read, Update, and Delete

Execute (E) - Includes Read and Update

Read (R)

None

NSX-T Data Center has the following built-in roles. Role names in the UI can be different in the API. In NSX-T Data Center, if you have permission, you can clone an existing role, add a new role, edit newly created roles, or delete newly created roles.
