Term
| T/F: your datastore will be formatted as VMFS when using NFS |
|
Definition
| False: NFS is not a block file system, therefore, your datastore will not be formatted as VMFS |
|
|
Term
| T/F: You need to perform masking and zoning with the host when setting up NFS |
|
Definition
| False: you are moving the file system from the host to the NFS server and therefore do not configure masking and zoning on the host. Instead you need to allow the IPs of your hosts to have r/w access to the appropriate shares |
