2V0-18.25 시험 - VMware실제시험문제와 답 - 100문항

Question No : 1

True or False: When importing an existing vSphere cluster into VVF 9.0, the cluster must use a vSphere Distributed Switch (VDS) for its networking; vSphere Standard Switches (VSS) are not supported for the final VVF cluster state.

A.True
B.False

정답:
Explanation:
VVF requires vSphere Distributed Switches (VDS) for managing network traffic consistently across the cluster. If the existing environment uses VSS, it must be migrated to VDS as part of the integration and import process.

Question No : 2

You are troubleshooting the upgrade of a VVF environment. The SDDC Manager pre-check fails for a specific workload domain.
What common issues could cause this pre-check failure? (Choose two.)

A.One or more ESXi hosts in the cluster are in Maintenance Mode.
B.There is insufficient free space on the vCenter Server appliance root partition.
C.The VMs in the cluster are running outdated VMware Tools.
D.The vSAN health checks are showing a completely green/healthy status.

정답:
Explanation:
Pre-checks validate the readiness of the environment for an upgrade. Hosts left in Maintenance Mode or lacking disk space on critical appliances like vCenter or NSX Manager are common reasons for pre-check failures.

Question No : 3

During the VVF 9.0 bring-up process, the validation phase fails because the NTP servers are unreachable.
How should this be addressed?

A.Skip the validation phase using the Cloud Builder AP
B.Configure the ESXi hosts to use their local BIOS clocks instead of NT
C.Verify the physical network routing and firewall rules between the ESXi management network and the NTP servers.
D.Deploy a temporary NTP server on the Cloud Builder appliance.

정답:
Explanation:
Time synchronization is critical for VCF/VVF components to function properly. If NTP validation fails, it is usually a network connectivity issue (routing, firewalls) that must be resolved on the physical network before proceeding with the deployment.

Question No : 4

When reviewing a failed workflow run in VCF Operations Orchestrator, you notice the execution state is "Canceled."
What does this indicate?

A.The workflow encountered an unhandled exception.
B.An administrator or another process manually stopped the workflow before it could complete.
C.The workflow timed out while waiting for a user interaction.
D.The Orchestrator server crashed during execution.

정답:
Explanation:
A "Canceled" state specifically means that the workflow execution was intentionally stopped by a user or an API call. Unhandled exceptions or script errors result in a "Failed" state.

Question No : 5

A custom workflow in VCF Operations Orchestrator interacts with a third-party REST API but keeps failing with authentication errors.
What are the best ways to troubleshoot this? (Choose two.)

A.Verify the credentials configured in the HTTP-REST plug-in endpoint.
B.Increase the CPU allocation for the Orchestrator appliance.
C.Use a REST API client (like Postman) with the same credentials to isolate the issue from Orchestrator.
D.Reinstall the Orchestrator appliance.

정답:
Explanation:
Authentication failures with REST APIs should be troubleshot by verifying the endpoint configuration within Orchestrator and testing the credentials externally using an API client to ensure the third-party system is accessible and accepting the credentials.

Question No : 6

You are asked to create a report in VCF Operations that details the capacity utilization of all VVF workload clusters.
Which component do you need to configure first before generating the report?

A.A custom Dashboard
B.A View
C.A Super Metric
D.An Alert

정답:
Explanation:
In VCF Operations, Reports are built based on "Views". You must first create or select a View (like a list or trend view of capacity metrics) and then include that View in the Report template to generate the PDF/CSV.

Question No : 7

True or False: VCF Operations Observability Workbench can automatically detect anomalous behavior in your VVF environment by establishing dynamic baselines for metrics.

A.True
B.False

정답:
Explanation:
VCF Operations uses machine learning to establish dynamic baselines (normal operating ranges) for metrics. The Observability Workbench uses these baselines to automatically highlight anomalous behavior and spikes during troubleshooting.

Question No : 8

A VVF engineer needs to troubleshoot an issue using VCF Operations for logs. The engineer wants to extract a specific error code from unstructured log messages to create a new dashboard widget.
Which feature should they use?

A.Log Forwarding
B.Extracted Fields
C.Content Packs
D.Interactive Analytics

정답:
Explanation:
Extracted Fields allow administrators to parse unstructured log data using regular expressions to extract specific values (like error codes) so they can be filtered, aggregated, and visualized in custom dashboards.

Question No : 9

While investigating network dropouts in a VVF environment, you decide to check the health of the VDS.
Which features of vSphere Network Health Check can assist you? (Choose two.)

A.VLAN and MTU check
B.Teaming and Failover check
C.BGP neighbor adjacency check
D.OSPF routing table check

정답:
Explanation:
vSphere Network Health Check for VDS can verify that the physical switch ports match the VDS settings for VLAN, MTU, and Teaming/Failover configurations. It does not check dynamic routing protocols like BGP or OSPF.

Question No : 10

You are troubleshooting a vSphere Distributed Switch (VDS) issue in VVF where virtual machines on different hosts cannot communicate with each other, but VMs on the same host can.
What is the most likely cause?

A.The VDS port group is configured with an incorrect VLAN ID, or the physical switch lacks the VLAN trunking configuration.
B.The virtual machines have VMware Tools uninstalled.
C.The ESXi hosts have different MTU settings on their vmk0 interfaces.
D.The VDS has run out of available logical ports.

정답:
Explanation:
If intra-host communication works but inter-host communication fails, the issue is almost always at the physical network layer or the uplink configuration, such as a missing VLAN on the physical switch trunk or a misconfigured VLAN ID on the port group.

Question No : 11

True or False: In a VVF environment using Fibre Channel (FC) storage, if an ESXi host loses connectivity to one of its two FC HBAs, the virtual machines on that host will immediately lose access to the datastore.

A.True
B.False

정답:
Explanation:
ESXi uses multipathing (such as Native Multipathing Plugin - NMP) to handle storage paths. If one HBA fails, the storage traffic will seamlessly failover to the surviving HBA without disrupting the VM's access to the datastore.

Question No : 12

A VVF administrator is troubleshooting high latency on a vSAN datastore.
Which of the following VCF Operations metrics would be most useful to investigate the vSAN performance? (Choose two.)

A.Read/Write Latency
B.Outstanding IOPS
C.CPU Ready Time
D.Network Dropped Packets

정답:
Explanation:
Read/Write Latency and Outstanding IOPS are direct storage performance metrics that help determine if the vSAN backend is struggling to keep up with the storage I/O demand from the virtual machines.

Question No : 13

You are troubleshooting a VVF cluster configuration issue where DRS is failing to migrate virtual machines to balance the load.
What is a common cause for this?

A.vSphere HA is disabled on the cluster.
B.The virtual machines have incompatible CPU features, and EVC is not enabled.
C.The ESXi hosts are using different vSAN datastores.
D.vMotion traffic is routed over the management network.

정답:
Explanation:
If Enhanced vMotion Compatibility (EVC) is not enabled and hosts have different CPU generations or features, DRS cannot perform live migrations (vMotion) because the VMs may rely on CPU instructions not present on the destination host.

Question No : 14

An ESXi host in a VVF cluster becomes unresponsive, and virtual machines are not automatically restarting on other hosts. You suspect an issue with vSphere HA.
Which log file on the primary HA host should you review?
A. fdm.log
B. vpxa.log
C. hostd.log
D. clomd.log

정답: A
Explanation:
The Fault Domain Manager (FDM) is the agent responsible for vSphere HA. The fdm.log file contains information about HA elections, host states, and VM restart attempts.

Question No : 15

A customer reports that a specific feature within VCF Operations is disabled. Upon investigation, you suspect a licensing issue.
Which components' licenses should be verified? (Choose two.)

A.The VVF core license applied in SDDC Manager.
B.The vSAN add-on license.
C.The individual VCF Operations license key.
D.The NSX Edge license key.

정답:
Explanation:
To use advanced features in VCF Operations, both the core VVF license (which grants base entitlements) and any specific VCF Operations advanced/enterprise license keys must be valid and correctly applied.
