VMware VCAP Infrastructure Troubleshooting

1. When troubleshooting storage performance, which metric indicates disk queue length?

DAVG

GAVG

KAVG

SAVG

2. When troubleshooting CPU contention on an ESXi host, which metric should you monitor?

Ready time percentage

User time percentage

System time percentage

Idle time percentage

3. What is the minimum number of hosts required for vSAN cluster functionality?

1

2

3

4

4. In vSphere, what is the role of the vMotion network?

Transfers VM memory and state during migration

Handles VM production traffic

Manages vCenter Server communication

Routes management commands to ESXi

5. Which vSphere feature automatically restarts failed VMs on healthy hosts?

High Availability (HA)

Distributed Resource Scheduler (DRS)

Fault Tolerance (FT)

Storage vMotion

6. When a VM snapshot reaches 100%, what is the recommended action?

Delete the snapshot and consolidate VM disk

Ignore; snapshots can grow indefinitely

Pause all VM operations

Migrate VM to another datastore

7. What is the maximum latency threshold for synchronous replication in vSphere Replication?

10 ms

100 ms

1000 ms

No hard limit; depends on configuration

8. Which command verifies vMotion compatibility between ESXi hosts?

Esxcli vm process list

Esxcli hardware cpu list

Esxcli vm snapshot list

Esxcli system version get

9. In a vSAN cluster, what happens if a host fails and data replicas exist?

VMs remain available; vSAN rebuilds data on other hosts

All VMs on that host shut down immediately

Cluster enters maintenance mode automatically

Datastore becomes read-only until repair

10. What is the purpose of the vCenter Server Appliance (VCSA) backup?

Backup VM configuration and vCenter database

Backup only ESXi host configurations

Backup only datastore content

Backup only network settings

11. What is the primary purpose of vSAN in a VMware VCAP environment?

Distributed storage abstraction layer for cluster-wide storage

Virtual networking protocol for east-west traffic

Hypervisor kernel module for CPU optimization

Management interface for vCenter Server

12. What is the default VLAN ID for management traffic on a standard vSwitch?

0

1

4094

No VLAN tagging by default

13. In vSphere Replication, what is the Recovery Point Objective (RPO)?

Maximum acceptable data loss between replications

Time to recover a failed VM

Bandwidth allocated for replication traffic

Number of replicated snapshots retained

14. Which vCenter Server role has permission to create and delete resource pools?

Virtual Machine Power User

Resource Pool Administrator

Administrator

Virtual Machine User

15. What does PSOD stand for in ESXi troubleshooting terminology?

Purple Screen of Death

Primary Storage of Distributed

Performance Snapshot on Demand

Protocol Switch on Disk

16. When a VM experiences network latency, which vSphere feature can prioritize its traffic?

Network I/O Control (NIOC)

Virtual Machine File System (VMFS)

Storage I/O Control (SIOC)

Distributed Power Management (DPM)

17. Which log file on an ESXi host contains general system messages and errors?

/var/log/syslog.log

/var/log/messages

/var/log/hostd.log

/var/log/vmkernel.log

18. In a DRS cluster, what does the 'Fully Automated' setting do?

Automatically migrates VMs to balance resource utilization

Requires manual approval for all VM migrations

Disables all load balancing features

Prioritizes network traffic over compute resources

19. What is the maximum number of vCPUs supported per VM in vSphere 7.0?

64

128

256

512

20. When troubleshooting a vMotion failure between hosts, which component is most critical to verify first?

VMotion network connectivity and MTU settings

VM memory allocation on destination host

Datastore capacity on source host

VCenter Server database connection
