Q191.

VTL emulates

Library and Tape drive

Library and Disk driver

Virtual Tape only

Any of the mentioned

Discuss

Answer: (a).Library and Tape drive

Q192.

Which of the following company manufacture San Fabric switches?

Emulex

Cisco

JNI

All of the mentioned

Discuss

Answer: (b).Cisco

Q193.

A “Logical Volume Manager” helps in

Virtualizing storage

provide direct access to the underlying storage

Manage disk space efficiently without having to know the actual hardware details

Both storage virtualization and efficient disk space management

Discuss

Answer: (d).Both storage virtualization and efficient disk space management

Q194.

Physical Volumes are

The space on a physical storage that represent a logical volume

Disk or disk partitions used to construct logical volumes

A bunch of disks put together that can be made into a logical volume

None of the mentioned

Discuss

Answer: (b).Disk or disk partitions used to construct logical volumes

Q195.

Logical Volumes _____

Can span across multiple volume groups

Can span across multiple physical volumes

Can be constructed only using a single physical disk

None of the mentioned

Discuss

Answer: (b).Can span across multiple physical volumes

Q196.

A logical Extent(LE) and Physical extent(PE) are related as follows

PE resides on a disk, whereas LE resides on a logical volume

LE is larger in size than a PE

LE’s are unique whereas PE’s are not

A LE can map to more than one PE

Discuss

Answer: (a).PE resides on a disk, whereas LE resides on a logical volume

Q197.

LVM is independent of device IDs because

LVM uses it’s own device naming to identify a physical disk

LVM stores the volume management information on the disks that helps it reconstruct volumes

LVM is an abstraction layer over physical devices and does not need device ids

Device ids are used only by the device drivers

Discuss

Answer: (b).LVM stores the volume management information on the disks that helps it reconstruct volumes

Q198.

Concatenation is the technique of

Adding physical volumes together to make a volume group

Filling up a physical volume completely before writing to the next one in a logical volume

writing a block of data onto one disk and then a block onto another disk in an alternate fashion

Increasing the size of a volume by adding more disks

Discuss

Answer: (b).Filling up a physical volume completely before writing to the next one in a logical volume

Q199.

Which of the following is not a feature of LVM

Independent of disk location

Concatenation and striping of storage systems

Protection against disk failures

Snapshot capability

Discuss

Answer: (c).Protection against disk failures

Q200.

LVM does not incur much performance overheads because

The writes/reads happen only to logical devices

The mapping of logical to physical storage is kept in RAM

The time lost in mapping devices is gained by writing to disks in parallel

None of the mentioned

Discuss

Answer: (b).The mapping of logical to physical storage is kept in RAM
