Filesystem Recovery Course - VMFS Recovery Test

VMFS stands for

virtual machine file structure
virtual machine file storage
virtual machine file system
volume manager file system

Where is small file repository stored on a VMFS volume?

one copy in the beginning and other – in the end
in the beginning of the volume
in the end of the volume

What is the recommended data recovery approach for a multi-disk VMFS volume?

first reassemble the volume from extents and then do filesystem recovery
do filesystem recovery on each disk separately
do RAID0 recovery first and then do filesystem recovery

How are large clusters numbered?

sequentially from the beginning of the volume
arbitrarily

What happens when a file is deleted?

an entire inode is overwritten with zeros
payload in the corresponding inode is overwritten with zeros
metadata in the corresponding inode is overwritten with zeros

What is the payload size?

1KB
2KB
512B
8KB

How inodes, indirect blocks table and small file repository are stored?

as regular files in the root filesystem directory
as special metadata structures

Can VMFS combine several physical disks?

yes, but only into JBOD
no
yes, but only into JBOD and mirror

Where are the numbers of the first and the last segments stored?

in the volume header
in the extent header

VMFS uses only contiguous areas on a disk to store files

false, files can be fragmented
true, files cannot be fragmented

We have a mailing list in which we talk about interesting cases we encounter and share some tips and tricks.
