A Cloud Admin is reviewing the inventory of a newly deployed VMware Cloud Foundation instance to verify the correct placement of appliances.
# VCF Inventory - Appliance List
vm-01: sddc-manager-01 (Power State: On)
vm-02: vcenter-mgmt-01 (Power State: On)
vm-03: nsx-manager-01 (Power State: On)
vm-04: nsx-edge-01 (Power State: On)
vm-05: vcenter-wld-01 (Power State: On)
vm-06: aria-ops-01 (Power State: On)
Which of the listed appliances primarily reside within the Management Domain's vSphere cluster?

An operator receives a ticket stating that "App-Server-A" cannot reach "DB-Server-B" over port 3306.
The operator suspects a firewall misconfiguration but is unsure if the block is happening at the Distributed Firewall (DFW), the Edge Gateway, or the Physical Firewall.
Which specific feature of VCF Operations for Networks should the operator use to diagnose this connectivity issue?

A deployment of VCF Operations for Networks is using "Pinning" to associate specific data sources with specific collectors.
# Scenario
Collector-A: Pinned to vCenter-Prod (High Load)
Collector-B: Pinned to vCenter-Test (Low Load)
# Alert
Collector-A is dropping flows due to overload (CPU 100%).
Collector-B is idle (CPU 10%).
What is the immediate remediation to balance the load without deploying new hardware?

In a distributed VCF Automation architecture, an administrator needs to manage a remote data center that is separated from the main management instance by a firewall with strict inbound blocking rules.
Which architectural component enables secure communication to the remote endpoint without opening inbound ports on the remote side?

An architect is deploying a Continuous Availability cluster. Where must the Witness Node be deployed to ensure proper split-brain protection?
