Tier-1 gateway: Network introspection services can be configured at the Tier-1 gateway level to inspect and control East-West traffic between workloads.

Partner SVM (Service Virtual Machine): Network introspection is often implemented through integration with a Partner SVM, which is a virtual machine provided by a third-party security partner to perform deep packet inspection and other security functions.

The ifconfig command is used to display the network configuration of interfaces, including the Tunnel Endpoint (TEP) IP on a bare metal transport node. This command provides details about IP addresses, subnet masks, and other network settings for each interface on the node.

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 web search results, network segmentation is a feature of NSX that improves the security of today’s modern workloads by preventing lateral movement. Lateral movement is a technique used by attackers to move from one compromised system to another within a network, exploiting vulnerabilities or credentials . Network segmentation prevents lateral movement by dividing a network into smaller segments or zones, each with its own security policies and controls. This way, if one segment is compromised, the attacker cannot access other segments or resources . NSX enables network segmentation by using micro-segmentation, which applies granular firewall rules at the virtual machine level, regardless of the physical network topology .

IPSec VPN services can be configured at Tier-0 and Tier-1 gateways: In NSX, IPSec VPN services can be applied to both Tier-0 and Tier-1 gateways, allowing secure site-to-site connections from these gateway levels.

IPSec VPNs use the DPDK accelerated performance library: NSX leverages the Data Plane Development Kit (DPDK) for optimized performance, which accelerates packet processing for IPSec VPNs and improves throughput.

According to the VMware documentation1, the clock icon appears on the firewall policy section that you want to have a time window. By clicking the clock icon, you can create or select a time window that applies to all the rules in that policy section. The other options are incorrect because they either do not exist or are not related to the time-based rule feature. There is no option to set a time-based rule in the rule itself, as it is a policy-level setting. There is also an option to set a time-based rule in the NSX UI, so it does not require using the command line interface.

To validate the BGP connection status between the Tier-0 Gateway and the upstream physical router on an NSX Edge node, the correct sequence involves enabling the specific logical router (Tier-0 Gateway), checking the VRF (Virtual Routing and Forwarding) context, and then using the show bgp neighbor command to view the BGP session status.

enable : This command enables the logical router interface (Tier-0 Gateway) to access its configuration.

get vrf : This command checks the specific VRF (used for routing separation) to see the associated routing table.

show bgp neighbor: This command displays the status of the BGP connection, including details about the neighbor relationships and their state.
