Q161

What happens when you change a VM's resource allocation from High to Normal?

  • A VM gets less CPU time
  • B VM becomes unresponsive
  • C VM loses all data
  • D VM gains more bandwidth
Explanation Changing to Normal decreases CPU priority, affecting time allocation negatively, unlike the other options.
Q162

You are configuring a vSphere environment with multiple ESXi hosts. Which feature is essential for VM mobility?

  • A VMware Tools
  • B vMotion
  • C Host Profiles
  • D Standard Switch
Explanation vMotion allows live migration of VMs, while the other options serve different purposes.
Q163

Which service manages VMware's NSX-T distributed firewall?

  • A NSX Manager
  • B vCenter Server
  • C vSphere Client
  • D ESXi Host
Explanation NSX Manager manages the distributed firewall, while vCenter cannot manage NSX functions directly.
Q164

A company needs to migrate virtual machines without downtime; which feature should they use?

  • A Cold Migration
  • B VMware vMotion
  • C Storage vMotion
  • D Long-Distance vMotion
Explanation VMware vMotion allows live migration of VMs with no downtime, unlike cold migration which is offline.
Q165

What happens when you set a VM's resource reservation to a high value?

  • A It consumes more resources immediately
  • B It guarantees a minimum resource allocation
  • C It prevents resource oversubscription
  • D It allocates CPU only on demand
Explanation A high resource reservation guarantees that the VM gets that minimum amount of resources regardless of load.
Q166

Which service is responsible for resource allocation in vSphere?

  • A vCenter Server
  • B ESXi Host
  • C vSAN
  • D VMware Tools
Explanation vCenter Server manages resource allocation, while other options have different roles.
Q167

A company needs to ensure its VMs are highly available. What feature should they enable?

  • A DRS
  • B HA
  • C vMotion
  • D Snapshots
Explanation HA (High Availability) restarts VMs on other hosts if a failure occurs, while DRS optimizes resource allocation.
Q168

You are configuring a VM's network settings in vSphere. What happens when you enable promiscuous mode?

  • A Blocks all non-matching traffic
  • B Allows all network traffic
  • C Observes traffic without interference
  • D Enables VLAN tagging
Explanation Promiscuous mode allows the VM to see all traffic on the network regardless of destination, unlike the other options.
Q169

Which service in vSphere provides detailed storage performance metrics?

  • A vSAN Health Service
  • B vSphere Replication
  • C Storage DRS
  • D vRealize Operations
Explanation vRealize Operations aggregates and analyzes performance metrics, while the other options focus on different aspects of storage management.
Q170

A company needs to automate the deployment of virtual machines with specific configurations. Which tool should they use?

  • A vSphere CLI
  • B Content Library
  • C VMware Cloud Director
  • D vRealize Automation
Explanation vRealize Automation is designed for automating deployments while the others are not focused specifically on this capability.
