A vSphere administrator needs to enable SSH on an ESXi host. Which method should be used?
AUse the vSphere Client.
BEdit the ESXi config file.
CRun 'esxcli local' command.
DPerform a host reboot.
Explanation
You can enable SSH through the vSphere Client, while the other options are not standard methods.
Q62
What happens when a VM is powered on but has no valid license?
AIt runs normally with limited features.
BIt displays a watermark but runs.
CIt fails to power on.
DIt automatically shuts down after 14 days.
Explanation
The VM will run but display a watermark indicating a licensing issue; it does not prevent operation.
Q63
You are configuring a VM with multiple vCPUs. What should you ensure for optimal performance?
AUse dedicated storage.
BPlace VMs on the same host.
CDistribute VMs across clusters.
DAvoid using oversubscribed resources.
Explanation
Avoiding oversubscription helps maintain performance; the other options may not specifically optimize CPU performance.
Q64
Which service provides high availability for VMs?
AVMware HA
BVMware VDR
CVMware FT
DVMware DPM
Explanation
VMware HA restarts VMs on other hosts if one fails; the others do not directly provide HA.
Q65
A company needs to limit bandwidth for specific VMs. What should they configure?
AResource Pools
BVM Options
CTraffic Shaping
DHost Profiles
Explanation
Traffic Shaping controls network bandwidth per VM; the others do not address bandwidth limits explicitly.
Q66
You are configuring a datastore for multiple hosts. What format is recommended for best performance?
ANFS
BVMFS
CvSAN
DiSCSI
Explanation
VMFS is optimized for multiple hosts accessing the same datastore; others may not perform as well with concurrent access.
Q67
Which service allows migration without downtime?
AVMware vMotion
BVMware Backup
CVMware Converter
DVMware Site Recovery
Explanation
vMotion enables live migration of VMs, minimizing downtime; the others do not have this live migration capability.
Q68
A company needs to replicate VMs across multiple sites. What solution should they use?
AVM Replication with Site Recovery Manager
BvSAN Stretch Cluster
CVM Snapshot
DLocal Backup
Explanation
VM Replication with Site Recovery Manager efficiently manages multi-site replication; other options are not designed for cross-site replication.
Q69
You are configuring a new distributed switch. What happens if you forget to add physical adapters?
AVMs will lose network connectivity
BTraffic will default to vSphere Standard Switch
CPhysical network will remain unaffected
DDistributed switch will still work
Explanation
Forgetting to add physical adapters will result in VMs losing network connectivity as there are no uplinks for the switch; other options misrepresent the functionality of distributed switches.
Q70
Which service in vSphere allows the implementation of Disaster Recovery strategies?
AvSphere Replication
BvSAN
CvRealize Operations
DVMware Tools
Explanation
vSphere Replication enables server replication for DR; vSAN is for storage, vRealize Operations for monitoring, and VMware Tools enhances VM functionality.
