To configure NSX Manager for two-factor authentication (2FA), an NSX administrator must have VMware Identity Manager (vIDM) with an OAuth Client added. vIDM provides identity management services and supports various 2FA methods, such as VMware Verify, RSA SecurID, and RADIUS. An OAuth Client is a configuration entity in vIDM that represents an application that can use vIDM for authentication and authorization. NSX Manager must be registered as an OAuth Client in vIDM before it can use 2FA. References: : VMware NSX-T Data Center Installation Guide, page 19. : VMware NSX-T Data Center Administration Guide, page 102. : VMware Blogs: Two-Factor Authentication with VMware NSX-T

The CLI command on NSX Manager and NSX Edge that is used to change NTP settings is set ntp-server. This command allows the user to configure one or more NTP servers for time synchronization12. The other options are incorrect because they are not valid CLI commands for changing NTP settings. The get timezone and set timezone commands are used to display and configure the timezone of the system1. The get time-server command is used to display the current time server configuration1. There are no CLI commands for using RADIUS or BootP for NTP settings. References: NSX-T Command-Line Interface Reference, vSphere ESXi 7.0 U3 and later versions NTP configuration steps

Network Introspection is a service insertion feature that allows third-party network security services to monitor and analyze the traffic between virtual machines. Network Introspection can be configured on the host pNIC or on the partner SVM, depending on the type of service and the deployment model. The host pNIC configuration is used for services that require traffic redirection from the physical network to the service virtual machine. The partner SVM configuration is used for services that require traffic redirection from the virtual network to the service virtual machine. Network Introspection cannot be configured on the Tier-0 or Tier-1 gateways, as they are not part of the data plane where the service insertion occurs. Network Introspection also cannot be configured on the edge node, as it is a logical construct that hosts the Tier-0 and Tier-1 gateways. References: Distributed Service Insertion, NSX Securing “Anywhere” Part IV

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

According to the VMware NSX 4.x Professional documents and tutorials, a RouterLink port is a logical port that connects a Tier-1 gateway to a Tier-0 gateway. This port is automatically created when a Tier-1 gateway is associated with a Tier-0 gateway from the NSX UI or API. The RouterLink port enables routing between the two gateways and carries all the routing protocols and traffic. There is no need to manually create a logical switch or segment for this purpose1.

esxcfg-nics -l and esxcli network nic list are two CLI commands that can be used to see the vmnic link status on an ESXi host. Both commands display information such as the vmnic name, driver, link state, speed, and duplex mode. The link state can be either Up or Down, indicating whether the vmnic is connected or not. For example, the output of esxcfg-nics -l can look like this:

Name PCI Driver Link Speed Duplex MAC Address MTU Description

vmnic0 0000:02:00.0 igbn Up 1000Mbps Full 00:50:56:01:2a:3b 1500 Intel Corporation I350 Gigabit Network Connection

vmnic1 0000:02:00.1 igbn Down 0Mbps Half 00:50:56:01:2a:3c 1500 Intel Corporation I350 Gigabit Network Connection

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.
