Which of the following protocols is used by an ESXi host to communicate with NAS storage? Question options: - SMB - CIFS - NFS - iSCSI
NFS
An administrator has been asked to configure a standard vSwitch for load balancing. Which load balancing policy provides the best overall load balancing while also requiring the most overhead processing? Question options: - Route based on source MAC hash - Route based on IP hash - Route based on originating port ID - Route using round robin
Route based on IP hash
Which of the following protocols is not used for block storage I/O? Question options: - NFS - Fibre Channel - iSCSI - FCoE
NFS not used for block I/O
True or False
Security policy has been configured on a standard vSwitch. You can configure security policy on a port group in order to override the vSwitch security policy.
False
You have been asked to increase the size of a VMFS datastore by adding an extent. Which of the following must you have to complete your task?
Question options:
- An unused iSCSI LUN
- A new unused NFS mount
- Free space on the LUN currently holding the VMFS datastore
- An RDM with sufficient space available
An unused ISCSI LUN
True or False
It is possible to unmount a datastore that contains virtual machines that are not running.
True
True or False
Configuring iSCSI on an ESXi host requires an iSCSI adapter. ESXi supports both hardware and software iSCSI adapters.
True
Explain the difference between vSphere both block and file I/O.
File level storage is seen and deployed in Network Attached Storage (NAS) systems.
- simple to use and implement.
- It stores files and folders and the visibility is the same to the clients accessing and to the system which stores it.
Block level storage is seen and deployed in Storage Area Network (SAN) storage.
- raw volumes of storage are created and each block can be controlled as an individual hard drive.
- controlled by server based operating systems and each block can be individually formatted with the required file system.
- This level of storage offers boot-up of systems which are connected to them.
- used to store files and can work as storage for special applications like databases, Virtual machine file systems and so on.
- Block level storage data transportation is much efficient and reliable.
You have added an RDM disk to a Windows Server based VM. What file system would be created on the LUN associated to the RDM?

True
True or False
A VM was created using VMware Workstation on someone’s desktop and its files have been uploaded to a datastore in vSphere. It is possible to register the VM in inventory and use it with no further modification.
True
Which of the following statements about vMotion migration is false?
Question options:
a) The VM is powered on at the time of the migration
b) The VM may not be migrated between data centers
c) vMotion involves migrating between hosts
d) The datastore containing the VM does not have to be accessible to all hosts involved in the migration
The datastore containing the VM does not have to be accessible to all hosts involved in the migration

You have a vSphere HA cluster with three hosts. You have configured host group consisting of one of your hosts. You have configured an affinity rule that your database VM must run on the host group. The host in the host group fails. What happens to the database VM?
a) The VM will be booted on one of the running hosts that is not in the host group.
b) vSphere will automatically add another host to the host group so that the VM can be rebooted.
c) The VM will stay powered down until the host in the host group is back on line.
d) vSphere will automatically change the affinity rule to allow the VM to boot on another host.
The VM will stay powered down until the host in the host group is back on line.
