Section 3 – Configure ESX/ESXi Storage
- Objective 3.3 – Configure NFS Datastores
Which of the following is true about use of the delegate user functionality that enables access to NFS devices using non-root credentials?
A.The functionality is not supported with ESX or ESXi 4.x
B.The functionality is experimental in ESX and ESXi 4.x
C.The functionality is supported in ESX, but not in ESXi 4.x
D.The functionality is fully supported in ESX and ESXi 4.x
vSphere4 Documentation Notes vReference.com Version 1.0 Page 1 Main Documentation Set, page 17.
ESX does not support the delegate user functionality that enables access to NFS volumes using non-root credentials.
ESXi does not support the delegate user functionality that enables access to NFS volumes using non- root credentials
What is the maximum configurable number of NFS datastores that can be mounted to an ESX/ESXi 4 Host?
Configuration Maximums VMware® vSphere 4.0 and vSphere 4.0 Update 1, page 4. Table 2. Storage Maximums NFS datastores 64
Which version of NFS does ESX Server require?
A.version 3 over UDP
B.version 3 over TCP
C.version 2 over UDP
D.version 2 over TCP
ESX Configuration Guide ESX 4.0, vCenter Server 4.0, Page 73.
The NFS client built into ESX uses Network File System (NFS) protocol version 3 to communicate with the NAS/NFS servers
At the time of introduction of Version 3, vendor support for TCP as a transport-layer protocol began increasing. While several vendors had already added support for NFS Version 2 with TCP as a transport, Sun Microsystems added support for TCP as a transport for NFS at the same time it added support for Version 3. Using TCP as a transport made using NFS over a WAN more feasible
An ESX Host gains exclusive access to Virtual Machines created on NFS datastores using?
A.Distributed File Locking
B.NFS File Locking Protocol
D.a special .lck-XXX lock file
ESX ESX Configuration Guide ESX 4.0 vCenter Server 4.0
When your host accesses a virtual machine disk file on an NFS-based datastore, a .lck-XXX lock file is generated in the same directory where the disk file resides to prevent other hosts from accessing this virtual disk file. Do not remove the .lck-XXX lock file, because without it, the running virtual machine cannot access its virtual disk file.
Which two statements are true about shared storage capabilities on NFS datastores supported by ESX Server (Choose Two)?
A.You can create Raw Device Mapped (RDM) virtual disks on NFS datastores
B.You can use Storage VMotion to move virtual machines between NFS datastores
C.You can cluster virtual machines using MSCS across ESX Servers using an NFS datastore
D.You can use VMware Consolidated Backup with an NFS datastore
Virtual Disks created on NFS datastores are?
A.in a format dictated by the NFS Server
Before configuring NFS on ESX Server, what must be configured?
A.a VMkernel port
B.the NFS Client service must be enabled in the Security Profile
C.the NFS Client must be enabled from the Service Console
D.a Service Console port
Which parameters are required when creating an NFS-based datastore in ESX Server?
A.NFS server CHAP, NFS shared folder name, datastore name
B.NFS server LUN UUID, NFS shared folder name, datastore name
C.NFS server World Wide Node Name, NFS shared folder name, datastore name
D.NFS server hostname, NFS shared folder name, datastore name
Which three statements are true about shared storage capabilities on NFS volumes supported by ESX Server? (Choose three.)
A.You can use VMotion.
B.You can configure ESX Server to boot from NFS mounted volumes.
C.You can boot virtual machines stored on NFS mounted volumes.
D.You can create virtual machines on NFS mounted volumes.
E.You can create VMFS datastore on NFS mounted volumes.
