Chapter 18 Disaster Recovery Planning

Question 1

This is also called striping. It uses two or more disks and improves the disk subsystem
performance, but it does not provide fault tolerance.

RAID-0
RAID-1
RAID-5
RAID-10

Answer 1

RAID-0

Question 2

This is also called striping with parity. It uses three or more disks with the equivalent of one disk holding parity information. If any single disk fails, the RAID array will
continue to operate, though it will be slower.

RAID-0
RAID-1
RAID-5
RAID-10

Answer 2

RAID-5

Question 3

_______ is configured as
two or more mirrors configured in a striped configuration. It uses at least four disks but can support more as long as an even number of disks are added. It will continue to operate even if multiple disks fail, as long as at least one drive in each mirror
continues to function.

RAID-0
RAID-1
RAID-5
RAID-10

Answer 3

RAID-10

Question 4

This is also called mirroring. It uses two disks, which both hold the same data.
If one disk fails, the other disk includes the data so a system can continue to operate after
a single disk fails.

RAID-10

Answer 4

RAID-1

Question 13

A _______
system will default to a secure state in the event of a failure, blocking all access.

fail-secure

Answer 13

fail-secure

Question 14

A system will fail in an open state, granting all access. The choice is dependent on
whether security or availability is more important after a failure.

fail-secure
fail-open

Answer 14

fail-open

_____ includes mechanisms
to ensure that specific objects are protected to prevent their loss.

Manual Recovery

Question 16

______ ensures that the system is able to successfully complete
the recovery for the functions, or that the system will be able to roll back the changes to
return to a secure state.

Manual Recovery
Automated Recovery
Automated Recovery without Undue Loss
Function Recovery

Answer 16

Function Recovery

Question 17

in ______ an administrator
is required to manually perform the actions necessary to implement a secured or
trusted recovery after a failure or system crash.

Manual Recovery
Automated Recovery
Automated Recovery without Undue Loss
Function Recovery

Answer 17

Manual Recovery

Question 18

The system is able to perform trusted recovery activities to restore
itself against at least one type of failure

Manual Recovery
Automated Recovery
Automated Recovery without Undue Loss
Function Recovery

Answer 18

Automated Recovery

Question 19

In an _____ scenario, database backups are moved to a remote site using bulk
transfers

Remote Mirroring
Electronic Vaulting
Remote Journaling

Answer 19

electronic vaulting

Question 20

Data transfers still occur in a bulk transfer mode, but they occur on a more frequent basis, usually
once every hour and sometimes more frequently.

Remote Mirroring
Electronic Vaulting
Remote Journaling

Answer 20

Remote Journaling

Question 21

______ a live database server is maintained
at the backup site. The remote server receives copies of the database modifi cations at
the same time they are applied to the production server at the primary site.

Remote Mirroring
Electronic Vaulting

_____ setups transfer copies
of the database transaction logs containing the transactions that occurred since the previous
bulk transfer.
