VMware VCP VCF Cluster Availability Quiz

1. What happens when a host becomes isolated in vSphere HA but continues running?

VMs are immediately terminated

VMs continue running on the isolated host

All VMs migrate to other hosts

The isolated host powers off automatically

2. Which monitoring tool helps identify cluster availability issues before failures occur?

VCenter Server health checks

Host performance graphs

VM snapshot status

License compliance reports

3. What is the relationship between vSphere HA and DRS in cluster availability?

HA restarts failed VMs; DRS balances resources

DRS restarts failed VMs; HA balances resources

Both provide identical failover capabilities

HA is only for storage; DRS is for compute

4. In VMware VCF, what is the purpose of the witness host in a stretched cluster?

Provides additional compute resources

Maintains cluster quorum during site failures

Handles all storage I/O operations

Manages network traffic between sites

5. Which vSphere feature prevents resource over-commitment in a cluster?

DRS automatic load balancing

Admission control

VM restart priority

Network isolation detection

6. What is the maximum recommended cluster size for vSphere HA stability?

8 hosts

16 hosts

32 hosts

64 hosts

7. In VCF, how does NSX-T contribute to cluster availability?

Provides network segmentation and load balancing

Manages storage replication

Monitors host hardware health

Controls vSphere HA parameters

8. What is the primary advantage of vSAN in cluster availability?

Shared storage without SAN hardware

Automatic VM encryption

Built-in backup capabilities

Network performance optimization

9. Which setting in vSphere HA controls how many host failures a cluster can tolerate?

Failure tolerance level

Admission control policy

Restart priority

Isolation response

10. In VMware VCF, what is the purpose of stretched clusters?

Extend cluster across geographic locations for disaster recovery

Increase cluster size beyond 32 hosts

Provide active-active replication

Enable cross-vCenter vMotion

11. What is the primary function of vSphere HA in a VMware cluster?

Monitor host failures and restart VMs on surviving hosts

Balance network traffic across cluster nodes

Optimize storage performance automatically

Manage license compliance across hosts

12. Which VMware feature automatically rebalances VMs across hosts to prevent resource contention?

VSphere HA

VSphere DRS

VSAN

NSX-T

13. In VCF, what role does the management domain play in cluster availability?

Hosts only workload VMs

Provides infrastructure services and manages workload domains

Serves as backup storage for datastores

Handles external network routing

14. What is the heartbeat mechanism in vSphere HA used for?

Detecting network latency between hosts

Monitoring host isolation from the cluster

Measuring CPU utilization

Tracking vCenter Server connectivity

15. Which vSphere HA restart priority setting ensures critical VMs restart first?

Low

Medium

High

Automatic

16. What is the purpose of DRS (Distributed Resource Scheduler) in cluster availability?

Restart failed virtual machines

Automatically migrate VMs to balance resource utilization

Monitor host health status

Manage storage replication

17. Which admission control policy reserves resources for HA failover by preventing VM placement?

Percentage of cluster resources

Slot-based admission control

Host failures cluster tolerates

All of the above

18. In VMware VCF, what is the minimum number of hosts required for a workload domain?

1 host

2 hosts

3 hosts

4 hosts

19. What does the isolation address in vSphere HA represent?

A network gateway used for host-to-host communication

A target IP to determine if a host is isolated from the network

The management IP of the vCenter Server

A backup DNS server for cluster resolution

20. Which component stores cluster configuration and heartbeat information in vSphere HA?

VCenter Server

Master host

Datastore

VSAN cluster
