4.1 RTO & RPO (Doshi)

Question 1

Recovery Point Objective (RPO)

Answer 1

A recovery point objective (RPO) is the period for which recent data will be irretrievably lost in a disaster.

Question 2

Extend of acceptable data loss:

Answer 2

It’s called Recovery Point Objective or RPO.

RPO POINT is most concerned by data loss

Question 3

RPO measures:

Answer 3

RPO is usually measured in hours or days.

Question 4

Recovery Time Objective:

Answer 4

Recovery time objective (RTO) is the period from the onset of an outage until the resumption of service.

Question 5

Extend of acceptable system downtime?

Answer 5

It’s called Recovery Time Objective or RTO

RTO Time is for system downtime.

Question 6

RTO measures:

Answer 6

RTO is usually measured in hours or days.

Question 7

What does a RTO of 2 hours indicate?

Answer 7

that organization needs to ensure that their system downtime should not exceed 2 hours.

Question 8

What does a RPO of 2 hours indicate?

Answer 8

that organization needs to ensure that their data loss should not exceed 2 hours of data captured.

Question 9

What should a RTO for a critical system be?

Answer 9

Zero or near Zero

Question 10

What should a RPO for a critical data be?

Answer 10

Zero or near Zero

Question 11

The lower RTO or RPO:

Answer 11

The higher the cost of maintenance environment

Question 12

What does a low RTO or RPO indicate?

Answer 12

That disaster tolerance is low. Therefore, if disaster tolerance is low, RTO/RPO should be low.

Question 13

What is recommended when RTO is low?

Answer 13

A mirrored site or hot site

Question 14

What is recommended when RPO is low?

Answer 14

Mirror imaging or real time replication for data back-up is recommended

Question 15

What is recommended when RPO is zero?

Answer 15

Synchronous data backup strategy to be used

Question 16

The lower the time requirements for RTO & RPO:

Answer 16

The higher, the cost of recovery strategies.

Question 17

RTO of 2 hours indicates that organization needs to ensure that their system downtime

Answer 17

should not exceed 2 hours.

Question 18

RPO of 2 hours indicates that organization needs to ensure that their data loss should

Answer 18

not exceed 2 hours of data captured.

Question 19

In any given scenario, for critical systems, RTO is

Answer 19

zero or near zero. Similarly, for critical data, RPO is zero or near zero.

Question 20

In any given scenario, lower the RTO/RPO,

Answer 20

higher the cost of maintenance of environment.

Question 21

In any given scenario, low RTO/RPO indicates that

Answer 21

disaster tolerance is low. Other way round, if disaster tolerance is low, RTO/RPO should be low.

Question 22

In any given scenario, when RTO is low,

Answer 22

mirrored site or hot site is recommended.

Question 23

In any given scenario, when RPO is low,

Answer 23

mirror imaging or real time replication for data back-up is recommended.

Question 24

In any given scenario, where RPO is zero,

Answer 24

synchronous data backup strategy to be used.

Question 25

Both RTO & RPO are based on

Answer 25

time parameters. The lower the time requirements, the higher the cost of recovery strategies.
