To enable east/west firewall in VMware Cloud Director Tenant Portal, you need to perform the following steps:

• Login to Customer Organization and go to Networking Section of Tenant Portal. This is where you can access the networking capabilities provided by NSX Data Center for vSphere in your VMware Cloud Director organization virtual data center.
• Go to Edge Gateways and enable firewall on one of the Edge Gateways. This will allow you to configure the edge gateway firewall rules for north/south traffic enforcement and perimeter security functionality. You can also enable other services such as NAT, VPN, load balancing, etc. on the edge gateway.
• Go to Networking and enable Distributed Firewall for one of the Network inside the Network section. This will allow you to configure the distributed firewall rules for east/west traffic isolation and access control. You can also apply security policies and groups to the network and the virtual machines within it.

 The frequency at which new services are discovered when using Service Discovery in vRealize Operations is every 5 minutes. Service Discovery is a feature of vRealize Operations that allows the administrator to discover and monitor the applications and services running on the virtual machines in the environment1. Service Discovery can be performed using two methods: credential-less and credential-based. Credential-less Service Discovery uses VMware Tools to query the guest operating system for the list of running processes, and then matches them with a predefined set of signatures to identify the applications andservices2. Credential-based Service Discovery uses the credentials provided by the administrator to log in to the guest operating system and run commands or scripts to discover the applications and services3. Credential-less Service Discovery collects the information about the services running inside the guest every five minutes4. Credential-based Service Discovery collects the information about the services running inside the guest every 24 hours5. Therefore, the frequency at which new services are discovered when using Service Discovery in vRealize Operations depends on the method used, but the most frequent one is every 5 minutes for credential-less Service Discovery. References:

 According to the VMware vRealize Operations Reference Materials, the cloud provider that needs to be added as a custom cloud provider when running a What-If Analysis is Oracle Cloud. The What-If Analysis feature allows the administrator to compare the cost and performance of running workloads in different public cloud providers, such as AWS, IBM Cloud, Microsoft Azure, Google Cloud, and Alibaba Cloud. These public cloud providers are supported out-of-the-box in vRealize Operations, and the administrator can select them from the predefined list when creating a migration scenario. However, if the administrator wants to compare the cost and performance of running workloads in Oracle Cloud, they need to add it as a custom cloud provider, and upload a rate card that contains the pricing information for Oracle Cloud services. The other options are incorrect because they are supported out-of-the-box in vRealize Operations, and they do not need to be added as a custom cloud provider when running a What-If Analysis. References: What-If-Analysis - Migration Planning: Public Cloud; VMware vRealize Operations What-If Analysis; VMware vRealize Operations for Public Cloud
