Test 14

Question 1

Hardware RAID Level 0: (Select all that apply)

Answer 1

Requires a minimum of 2 drives to implement ( Missed)
Is also known as disk striping ( Missed)
Decreases reliability (failure of any disk in the array results in the loss of all data in the array)
Is suitable for systems where performance has higher priority than fault tolerance

Question 2

Hardware RAID Level 1: (Select 3 answers)

Answer 2

Requires at least 2 drives to implement
Offers improved reliability by creating identical data sets on each drive (failure of one drive does not destroy the array as each drive contains identical copy of the data) ( Missed)
Is also referred to as disk mirroring

Question 3

Hardware RAID Level 5: (Select 3 answers)

Answer 3

Requires at least 3 drives to implement ( Missed)
Offers increased performance and fault tolerance (single drive failure does not destroy the array and lost data can be re-created by the remaining drives)
Is also known as disk striping with parity

Question 4

Hardware RAID Level 6: (Select 3 answers)

Answer 4

Requires at least 4 drives to implement ( Missed)
Offers increased performance and fault tolerance (failure of up to 2 drives does not destroy the array and lost data can be re-created by the remaining drives)
Is also known as disk striping with double parity

Question 5

Hardware RAID Level 10 (a.k.a. RAID 1+0): (Select 3 answers)

Answer 5

Requires a minimum of 4 drives to implement ( Missed)
Is referred to as stripe of mirrors, i.e., a combination of RAID 1 (disk mirroring) and RAID 0 (disk striping) ( Missed)
Requires a minimum of 5 drives to implement
Offers increased performance and fault tolerance (failure of one drive in each mirrored pair of disk drives does not destroy the array) ( Missed)

Question 6

Which of the following RAID levels does not offer fault tolerance?

Answer 6

RAID 0

Question 7

Which of the answers listed below refers to the primary function of load balancing?

Answer 7

Distributes workload across multiple servers for improved performance

Question 8

Which of the following is the primary function of clustering?

Answer 8

Groups servers together to provide high availability and fault tolerance

Question 9

Which of the terms listed below refers to a duplicate of the original site, with fully operational computer systems as well as near-complete backups of user data?

Answer 9

Hot site

Question 10

Which of the following terms refers to an alternate site that provides some pre-installed hardware and software and might have partial data backups, but it is not fully operational and requires additional configuration before use?

Answer 10

Warm site

Question 11

A disaster recovery facility that provides only the physical space for recovery operations is known as:

Answer 11

Cold site

Question 12

Which alternate site is the least expensive to implement?

Answer 12

Cold site

Question 13

Which alternate site allows for the fastest disaster recovery?

Answer 13

Hot site

Question 14

What is the name of a U.S. government initiative that provides a set of procedures and plans that an organization can implement to ensure continued performance of its essential functions during unexpected events?

Answer 14

COOP

Question 15

Which of the answers listed below refers to a simulated scenario conducted in a controlled environment, typically involving discussions and planning around hypothetical security incidents?

Answer 15

Tabletop exercise

Question 16

The process of switching to a redundant or standby system upon detecting a disruption in the primary system is called:

Answer 16

Fail over

Question 17

Which of the following answers refers to a more realistic scenario that tests cybersecurity incident response by mimicking actual attacks?

Answer 17

Simulation

Question 18

Which of the solutions listed below provides redundancy and fault tolerance by dividing tasks into smaller subtasks and distributing them across multiple systems to be executed simultaneously?

Answer 18

Parallel processing

Question 19

A file-based representation of the state of a virtual machine at a given point in time is referred to as:

Answer 19

Snapshot

Question 20

What type of backups are commonly used with virtual machines?

Answer 20

Snapshot backups

Question 21

Which of the following terms refers to a backup strategy that relies on creating and maintaining copies of data in real-time or near real-time on a separate system?

Answer 21

Replication

Question 22

A technique that allows to recover changes that occurred since the last backup in the event of a system crash is known as:

Answer 22

Journaling

Question 23

Which of the answers listed below refers to a device designed to supply (and monitor the quality of) electric power to multiple outlets?

Answer 23

PDU

Question 24

What is the name of a device that can provide short-term emergency power during an unexpected main power source outage?

Answer 24

UPS

Question 25

Which of the following power redundancy solutions would be best suited for providing long-term emergency power during an unexpected main power source outage?

Answer 25

Backup generator
