Which VCF Operations feature allows an administrator to retain statistical summaries (e.g., Monthly Maximum, Monthly Average) of metrics for 5 years, while deleting the raw 5-minute data points after 6 months to save space?

A team uses Ansible (Open Source) heavily for application configuration. They want to drag-and- drop their existing Ansible Playbooks onto the VCF Automation design canvas to run post-provisioning tasks on new VMs.
Which prerequisite must be met to enable this capability?

A Cloud Admin is preparing to migrate a complex multi-tier application ("Legacy-App-01") to a new Workload Domain. The application documentation is outdated, and the admin needs to identify exactly which VMs communicate with each other and on which ports, to define the correct firewall rules.
# Requirement
- Map all dependencies (Web -> App -> DB).
- Identify used ports/protocols.
- Export recommended firewall rules.
Which tool is designed to perform this "Application Discovery and Dependency Mapping"?

A customer has configured IPFIX on their Distributed Switch to send flows to the VCF Operations for Networks Collector. However, the "Flow Traffic" dashboard shows 0 flows received.
# Troubleshooting Steps
- Port 2055 is open on the firewall.
- Collector services are running.
- IPFIX target IP is correct.
What VDS configuration mismatch often causes this issue?

An operator is troubleshooting a failed Workload Domain creation workflow. The "Validation" stage failed with an error regarding insufficient resources. The operator reviews the available hosts in the VCF Inventory.
