The VCF Operations for Networks (formerly vRNI) enables Application Discovery and Network Visibility . According to VCF 9.0: “ Operations for Networks provides flow-based application discovery, dependency mapping, and security planning. This allows administrators to visualize application topology and relationships across the VCF fleet. ” By contrast, VCF Operations for Logs provides log aggregation, while the Collector provides integration for metrics, not discovery. The vSphere Supervisor enables Kubernetes workloads, not application discovery. Therefore, to achieve Service and Application Discovery , administrators must deploy VCF Operations for Networks .

The documentation clarifies the scenario when a password is changed outside of VCF Operations: “ When an error occurs, for example after a password expires, you must manually reset the password in the component product. After you reset the password in a component, you must remediate the password in VCF Operations. ” “Password Rotation” is different—it “ allows you to orchestrate the rotation ” of stored credentials (a planned, VCF-driven change), not reconcile an externally altered password. Therefore, after the direct password change in vCenter, the correct recovery step in VCF Operations is to use Remediate password to synchronize credentials and restore management from VCF Operations.

Memory tiering in modern vSphere environments allows hosts to utilize different memory technologies (e.g., DRAM and persistent memory tiers) to optimize cost and performance.

The vSphere documentation explains:

“Memory tiering enables efficient placement of memory pages across different memory types, optimizing performance and capacity for memory-intensive workloads.”

The primary use case is for:

Large in-memory databases

Analytics workloads

Memory-intensive applications

Incorrect options:

It does not primarily reduce swap for small VMs (A).

It does not directly boost CPU throughput (B).

It does not address host availability during hardware failure (C).

Thus, memory tiering is best suited for optimizing memory usage for large, memory-intensive workloads .
