Q171

What happens when you change a VM's resource allocation while it is powered on?

  • A VM will crash immediately
  • B No effect until next power cycle
  • C Changes apply without interruption
  • D VM performance will degrade instantly
Explanation Resource allocation changes take effect without downtime, while options A and D are false as they incorrectly predict crashes or degradation.
Q172

Which service is crucial for managing vSphere lifecycle and inventory?

  • A vCenter Server
  • B ESXi Host
  • C vSphere Replication
  • D VMware Tools
Explanation vCenter Server centralizes lifecycle management, while others serve different functions.
Q173

A company needs to ensure VMs remain operational during host failures. What feature should they implement?

  • A VM Monitoring
  • B vSphere High Availability
  • C Resource Pools
  • D Storage DRS
Explanation vSphere High Availability restores VMs automatically, while others do not address host failures directly.
Q174

What happens when you set a VM's CPU affinity to a specific host?

  • A Increased CPU performance guaranteed
  • B VM can only run on that host
  • C CPU resources become unbalanced
  • D All hosts become unusable
Explanation Setting CPU affinity restricts VM operation to a single host, affecting resource optimization.
Q175

Which service provides orchestration for multi-cloud deployments?

  • A VMware Cloud Director
  • B VMware vCenter Server
  • C VMware vRealize Automation
  • D VMware NSX
Explanation VMware vRealize Automation specializes in multi-cloud orchestration, while others focus on specific functionalities.
Q176

A company needs to segment its virtual network traffic for security. What should they implement?

  • A VLANs
  • B NAT
  • C IPSec
  • D VPN
Explanation VLANs efficiently segment network traffic; NAT and IPSec serve different purposes.
Q177

You are configuring DRS in a cluster with strict CPU reservations. What happens when a VM exceeds its reservation?

  • A It is powered off
  • B Performance Degrades
  • C DRS ignores it
  • D Fails to migrate
Explanation Exceeding the reservation causes performance degradation, as allocated resources are maxed out, leading to contention.
Q178

Which service manages distributed resource scheduling in vSphere 8?

  • A DRS
  • B vSAN
  • C NAT
  • D SSL
Explanation DRS stands for Distributed Resource Scheduler, which allocates resources efficiently. The other options do not manage resource scheduling.
Q179

A company needs to increase security for its virtual machines. Which feature should they implement?

  • A VM Encryption
  • B Resource Pools
  • C VM Snapshots
  • D DPM
Explanation VM Encryption secures virtual machine data and disk files. Resource Pools and Snapshots do not enhance security, while DPM relates to power management.
Q180

What happens when a virtual machine exceeds its allocated CPU limits?

  • A CPU usage is throttled
  • B The VM crashes
  • C Performance improves
  • D CPU is reallocated
Explanation The VM's CPU usage is throttled to adhere to limits. The other options incorrectly describe outcomes of exceeding CPU limits.
