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.

A) Can be used as an Exterior Gateway Protocol. This is correct. BGP is a protocol that can be used to exchange routing information between different autonomous systems (AS). An AS is a network or a group of networks under a single administrative control. BGP can be used as an Exterior Gateway Protocol (EGP) to connect an AS to other ASes on the internet or other external networks1 B) It supports a 4-byte autonomous system number. This is correct. BGP supports both 2-byte and 4- byte AS numbers. A 2-byte AS number can range from 1 to 65535, while a 4-byte AS number can range from 65536 to 4294967295. NSX supports both 2-byte and 4-byte AS numbers for BGP configuration on a Tier-0 Gateway2 C) The network is divided into areas that are logical groups. This is incorrect. This statement describes OSPF, not BGP. OSPF is another routing protocol that operates within a single AS and divides the network into areas to reduce routing overhead and improve scalability. BGP does not use the concept of areas, but rather uses attributes, policies, and filters to control the routing decisions and traffic flow3 D) FIGRP Is disabled by default. This is correct. FIGRP stands for Fast Interior Gateway Routing Protocol, which is an enhanced version of IGRP, an obsolete routing protocol developed by Cisco.
FIGRP is not supported by NSX and is disabled by default on a Tier-0 Gateway.
E) BGP is enabled by default. This is incorrect. BGP is not enabled by default on a Tier-0 Gateway. To enable BGP, you need to configure the local AS number and the BGP neighbors on the Tier-0 Gateway using the NSX Manager UI or API.
To learn more about BGP configuration on a Tier-0 Gateway in NSX, you can refer to the following resources:

According to the web search results, VMware Aria Operations Networks (formerly vRealize Network Insight) is a network monitoring tool that can help monitor, discover and analyze networks and applications across clouds1. It can also provide enhanced troubleshooting and visibility for physical and virtual networks2.
The other options are either incorrect or not relevant for identifying problems in a physical network.
VMware Aria Automation is a cloud automation platform that can help automate the delivery of IT services. VMware Aria Orchestrator is a cloud orchestration tool that can help automate workflows and integrate with other systems. VMware Site Recovery Manager is a disaster recovery solution that can help protect and recover virtual machines from site failures.

An overlay segment is a layer 2 broadcast domain that is implemented as a logical construct in the NSX- T Data Center software. Overlay segments do not require any configuration on the physical switches, and they allow for optimal east/west communication between workloads on different ESXi hosts. Overlay segments use the Geneve protocol to encapsulate and decapsulate traffic between the hosts. Overlay segments are created and managed by the NSX Manager.

BGP Neighbors: This parameter is essential for establishing BGP sessions with other routers. Configuring BGP neighbors allows VRF Lite gateways to exchange routing information with adjacent BGP-enabled devices.
Local AS: The Local Autonomous System (AS) number can be set for the VRF Lite gateway, which is necessary for BGP operations within a specific routing domain.
