Which VCF Automation component serves as the underlying workflow engine, allowing administrators to run custom JavaScript or Python scripts to extend the platform's capabilities (e.g., updating a CMDB or IPAM system during a deployment)?

A Solution Architect is designing the integration strategy for a VCF environment that includes a
"Stretched Cluster" Management Domain across two sites. The requirement is to ensure continuous monitoring of the Management vCenter even if Site 1 goes dark.
# Architecture
Site 1: Primary vCenter Node (Active)
Site 2: vCenter HA Node (Passive)
VCF Operations: Deployed in Site 1 (Standard Cluster)
# Issue
If Site 1 fails completely, VCF Operations (in Site 1) will also go down, failing to monitor the failover of vCenter to Site 2.
To enable true continuous monitoring survivability for the vCenter integration during a Site 1 failure, what architectural change is required?

A solution architect is designing a Collector Group for a high-traffic environment.
# Requirements
- 50,000 Metrics per second.
- 2 Cloud Proxies in the Group.
# Policy
"If one Cloud Proxy fails, the other must handle the full load without dropping data." What sizing principle must be applied to the individual Cloud Proxies in this group?

A VCF Operator needs to find all logs containing the word "Error" but explicitly wants to exclude any logs containing the word "Maintenance" to reduce noise during a scheduled window.
How is this negative query constructed in the Interactive Analytics search bar?

An integration status shows "Data Receiving" (Green/Blue), yet the dashboards show "No Data" or flat-lined metrics for the last 2 hours.
# Investigation
- Collector is online.
- Target is online.
- No connectivity errors in logs.
What is a subtle but common infrastructure cause for this behavior?
