An operator needs to take the "Master Node" of a VCF Operations HA cluster offline for hardware maintenance (RAM upgrade). The cluster is currently healthy.
What is the correct procedure to ensure zero downtime for the cluster during this maintenance?

A deployment plan calls for VCF Operations to be integrated with "Azure Active Directory" (Entra ID) via SAML 2.0, rather than legacy LDAP.
Which VCF component is required to act as the Service Provider (SP) intermediary to facilitate this modern authentication flow?

An operator clicks the "Optimize Now" button to manually trigger a workload rebalance. The task fails immediately with an error indicating "Action Execution is disabled".
Where must the operator go to fix this permission issue?

A Cloud Admin configures a "Kubernetes" integration to monitor a TKG cluster. The connection test succeeds, but no metrics appear. The "Collection State" shows "Warning".
# Warning Message
"Collection is running, but 0 Pods found. Verify permissions."
# Credential Used
Service Account: 'vrops-monitor'
Role Binding: 'view' (Namespace specific)
What is the likely cause?

An architect is designing a Disaster Recovery (DR) strategy for a "Standard Availability" (non- stretched) VCF Operations cluster located in the primary data center (Site A). The requirement is to recover the monitoring capability in the secondary data center (Site B) with a Recovery Point Objective (RPO) of 15 minutes.
# Constraints
- Site A and Site B are connected via high latency link (100ms).
- Continuous Availability (CA) is NOT an option due to latency.
- Site Recovery Manager (SRM) is available.
Which DR method meets the requirements?
