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 VMware NSX Documentation, these are two of the ways that you can use to configure Distributed Firewall on VDS:

NSX API: This is a RESTful API that allows you to programmatically configure and manage Distributed Firewall on VDS using HTTP methods and JSON payloads. You can use tools such as Postman or curl to send API requests to the NSX Manager node.

NSX UI: This is a graphical user interface that allows you to configure and manage Distributed Firewall on VDS using menus, tabs, buttons, and forms. You can access the NSX UI by logging in to the NSX Manager node using a web browser.

According to the VMware NSX Documentation, Switch Visualization is a feature in the NSX UI that shows the mapping between the virtual NIC and the host's physical adapter for virtual machines running on an ESXi transport node. You can use Switch Visualization to view details such as port ID, MAC address, VLAN ID, IP address, MTU, port state, port speed, port type, and port group for each virtual NIC and physical adapter.

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.

NSX supports two types of authentication, authorization, and accounting (AAA) systems when integrating with VMware Identity Manager: RSA SecurID and LDAP and OpenLDAP based on Active Directory (AD). RSA SecurID is a two-factor authentication system that uses a token-based approach to verify the identity of users. LDAP and OpenLDAP based on AD are directory services that store and manage user information and credentials. Both systems can be used to provide centralized authentication for users who want to access applications in an NSX environment .

The integration of VMware Identity Manager with NSX provides the following benefits related to user authentication:

* Support for extensive authentication, authorization, and accounting (AAA) systems, including:

--- RADIUS

--- Smart cards and common access cards

--- RSA SecureID

--- LDAP and OpenLDAP based on Active Directory (AD)

* Enterprise SSO:

--- Common authentication platform across multiple VMware solutions

--- Seamless SSO experience

NSX has its own native LDAP and Active Directory integration, but VMware Identity Manager also offers this capability

L2 VPN is a feature of NSX that allows extending Layer 2 networks across different sites or clouds over an IPsec tunnel. L2 VPN has an advantage of enabling VM mobility with re-IP, which means that VMs can be moved from one site to another without changing their IP addresses or network configurations. This is possible because L2 VPN allows both sites to use the same broadcast domain, which means that they share the same subnet and VLAN .

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 <fiilename>

get log-file <filename> 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
