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

The RouterLink port is automatically created when a Tier-1 Gateway is connected with a Tier-0 Gateway from the NSX UI1. The RouterLink port is a logical interface that is assigned an IP address and is associated with a physical or virtual interface.The RouterLink port acts as an end point of the IPSec tunnel and routes traffic between the Tier-1 Gateway and the Tier-0 Gateway2. The other options are incorrect because they involve manual creation of logical switches or segments, which are not required for RouterLink port creation.Reference:Configure NSX for Virtual Networking from vSphere Client,Virtual Private Network (VPN)

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.

The answer is A. SR is instantiated and automatically connected with DR.

SR stands for Service Router and DR stands for Distributed Router. They are components of the NSX Edge node that provide different functions1

The SR is responsible for providing stateful services such as NAT, firewall, load balancing, VPN, and DHCP. The DR is responsible for providing distributed routing and switching between logical segments and the physical network1

When a stateful service is enabled for the first time on a Tier-0 Gateway, the NSX Edge node automatically creates an SR instance and connects it with the existing DR instance. This allows the stateful service to be applied to the traffic that passes through the SR before reaching the DR2

According to the VMware NSX 4.x Professional Exam Guide, understanding the SR and DR components and their functions is one of the exam objectives3

To learn more about the SR and DR components and how they work on the NSX Edge node, you can refer to the following resources:

According to the VMware NSX Documentation, these are three of the capabilities of Network Topology, which is a graphical representation of your network infrastructure in NSX:

Display how the different NSX components are interconnected: You can use Network Topology to view how your segments, gateways, routers, firewalls, load balancers, VPNs, and other NSX components are connected and configured in your network.

Display the uplink configured on the Tier-0 Gateways: You can use Network Topology to view the uplink interface and segment that connect your tier-0 gateways to your physical network. You can also view the VLAN ID and IP address of the uplink interface.

Display the VMs connected to Segments: You can use Network Topology to view the VMs that are attached to your segments. You can also view the IP address and MAC address of each VM.
