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.

 According to the vRealize Operations User Guide1, one of the best ways to quickly identify the underlying problem of slow application VMs is to use the out-of-the-box Performance dashboards that display contention on both VMs and ESXi hosts. These dashboards show the key performance indicators (KPIs) of CPU, memory, disk, and network for the selected objects, and highlight any contention or saturation issues that may affect the performance. The administrator can use these dashboards to drill down into the details of the metrics, alerts, events, and properties of the objects, and isolate the root cause of the problem. The other options are not correct because:

• Under Inventory, selecting Manage Agent, then selecting the VMs, and running Remote Checks on ICMP, HTTP checks is not a helpful action, as it only verifies the connectivity and availability of the VMs, but does not provide any information about the performance or contention of the VMs or the ESXi hosts2.
• Under Report, using Configuration Report - Virtual Machines to list down possible changes that have occurred is not a helpful action, as it only shows the configuration details of the VMs, such as name, UUID, power state, guest OS, CPU, memory, disk, and network, but does not show any performance or contention metrics or alerts of the VMs or the ESXi hosts3.
• Under Administration, choosing Configuration, selecting Object Relationships, and then identifying the VMs and ESXi hosts relationship to generate a correlation of the metric, and finally, isolate the issue is not a helpful action, as it only shows the hierarchical and logical relationships between the objects, such as parent, child, sibling, and peer, but does not show any performance or contention metrics or alerts of the objects4. References: 1: vRealize Operations User Guide, pages 57-59, 62-632: vRealize Operations User Guide, pages 69-703: vRealize Operations User Guide, pages 81-824: vRealize Operations User Guide, pages 84-85.

According to the VMware vRealize Operations Reference Materials, the Wait Cycle and the Cancel Cycle are the settings that determine how long a symptom condition must be true or false before the symptom is triggered or cancelled. The default cycle for both settings is 5 minutes, which means that each cycle corresponds to one collection interval of 5 minutes. Therefore, if a symptom has a Wait Cycle of 3 and a Cancel Cycle of 2, it will take 15 minutes (3 cycles x 5 minutes) for the symptom to be triggered after the condition becomes true, and 10 minutes (2 cycles x 5 minutes) for the symptom to be cancelled after the condition becomes false. The other options are incorrect because they do not match the calculation based on the given settings and the default cycle. References: Symptom Definition Settings; Alert Definition Best Practices
