VCP Technology & Digital Tools 5 — Questions and Answers
Question 1: Which VMware tool provides proactive support by collecting telemetry from vSphere environments and identifying potential issues before they cause outages?
- VMware Skyline (Correct answer)
- vRealize Log Insight
- vSphere Health
- VMware Aria Operations
Correct answer: VMware Skyline
VMware Skyline is a proactive support technology that continuously analyzes telemetry data from customer environments to identify known issues and provide remediation guidance before problems occur.
Question 2: What is the maximum number of vCPUs that vSphere Fault Tolerance (FT) supports per protected VM in vSphere 7.0 and later?
- 8 vCPUs (Correct answer)
- 4 vCPUs
- 16 vCPUs
- 32 vCPUs
Correct answer: 8 vCPUs
vSphere 7.0 supports up to 8 vCPUs per Fault Tolerant VM, an increase from the 4 vCPU limit in earlier versions.
Question 3: Which network I/O feature on a vSphere Distributed Switch allows administrators to prioritize traffic types by assigning shares, limits, and reservations?
- Network I/O Control (NIOC) (Correct answer)
- Traffic Shaping Policy
- Link Aggregation Control Protocol (LACP)
- Port Mirroring
Correct answer: Network I/O Control (NIOC)
Network I/O Control (NIOC) enforces quality-of-service policies on distributed switch uplinks by categorizing traffic into system-defined traffic types and applying bandwidth allocation settings.
Question 4: A company needs to run containers alongside VMs on the same vSphere infrastructure. Which VMware technology enables native Kubernetes integration with vSphere?
- vSphere with Tanzu (formerly Project Pacific) (Correct answer)
- VMware NSX-T Container Plugin
- vSphere Integrated Containers (VIC)
- VMware PKS (Pivotal Container Service)
Correct answer: vSphere with Tanzu (formerly Project Pacific)
vSphere with Tanzu embeds Kubernetes directly into the vSphere hypervisor, enabling administrators to run containers and VMs on the same platform managed through vCenter.
Question 5: Which vSphere security feature uses a hardware-based Trusted Platform Module (TPM) to verify ESXi host boot integrity?
- Secure Boot with TPM attestation
- vSphere Trust Authority (vTA) (Correct answer)
- VM Encryption
- vSphere Trusted Hosts
Correct answer: vSphere Trust Authority (vTA)
vSphere Trust Authority (vTA) uses TPM 2.0 chips to cryptographically attest the integrity of ESXi host boot configurations, ensuring hosts have not been tampered with before they receive encryption keys.
Question 6: What is the purpose of VMware vSphere's Storage I/O Control (SIOC)?
- Prioritizes VM storage access during periods of I/O contention on shared datastores (Correct answer)
- Automatically provisions new LUNs when storage thresholds are reached
- Encrypts VM disk I/O at the hypervisor layer
- Replicates storage blocks to a secondary array
Correct answer: Prioritizes VM storage access during periods of I/O contention on shared datastores
SIOC monitors datastore latency and, when congestion thresholds are exceeded, enforces per-VM shares to ensure higher-priority VMs receive proportional access to storage I/O.
Question 7: Which VMware vSphere REST API endpoint is used by modern tooling like PowerCLI 12+ and Terraform to manage vCenter programmatically?
- vSphere Automation API (formerly vSphere REST API) (Correct answer)
- vSphere Web Services SDK (SOAP)
- vSphere Management SDK (MOB)
- vCloud API
Correct answer: vSphere Automation API (formerly vSphere REST API)
The vSphere Automation API provides a modern REST-based interface for managing vCenter resources, replacing legacy SOAP-based calls with JSON-over-HTTPS endpoints.
