Q141

What happens when a VM exceeds its resource reservation?

  • A It gets additional resources from shared pool
  • B It is throttled and cannot perform operations
  • C It powers off automatically
  • D It maintains performance, unaffected by limits
Explanation When a VM exceeds its reservation, it can utilize resources from the shared pool; other options incorrectly describe the VM’s behavior.
Q142

Which service enables automated resource provisioning in VMware?

  • A vSphere Resource Pools
  • B VMware vRealize Automation
  • C VMware ESXi Host
  • D vCenter Server
Explanation vRealize Automation automates resource provisioning, while others manage resources or infrastructure.
Q143

A company needs to optimize storage usage for their VMs. What should they implement?

  • A VMware DRS
  • B VMware Storage DRS
  • C VMware FT
  • D VMware vMotion
Explanation Storage DRS optimizes storage allocation across datastores, unlike other solutions that don't specifically address storage efficiency.
Q144

What happens when a VM exceeds its configured resource limits?

  • A VM shuts down immediately
  • B VM performance is throttled
  • C Resource allocation increases automatically
  • D VM cannot access any resources
Explanation Exceeding limits results in throttled performance without shutting down the VM or limiting access all together.
Q145

Which service is used for network security in VMware environments?

  • A VMware NSX
  • B VMware vSphere
  • C VMware Horizon
  • D VMware vSAN
Explanation VMware NSX provides network virtualization and security, while others serve different purposes.

  • A Migration fails and VM restarts
  • B VM remains in its current state
  • C Migration completes without issues
  • D VM data gets corrupted
Explanation Accidental power loss causes the migration to fail and the VM may restart from the last snapshot.
Q148

Which service allows automated VM scaling based on load?

  • A VMware vSphere Auto Scaling
  • B VMware DRS
  • C vSphere FT
  • D vCenter Server
Explanation VMware DRS automatically balances VMs across hosts; the other options do not provide automated scaling capabilities.
Q149

A company needs to securely connect to vCloud environment from remote offices. What should they implement?

  • A Direct public IP access
  • B VPN connections
  • C Dynamic DNS service
  • D Public VDC
Explanation VPN connections ensure secure, encrypted access; other options may expose the network to risks.
Q150

You are configuring resource pools in a cluster. What happens when you oversubscribe CPU resources?

  • A Performance will increase
  • B No impact, always sufficient
  • C Performance may degrade
  • D Resources are automatically deallocated
Explanation Oversubscribing CPU can lead to contention and degraded performance; the other options are incorrect or misleading.
