Question 1

Image backup is attractive because ________.
A) it requires minimal additional work to restore a fully functioning PC
B) it is faster than file/directory backup
C) it takes up less storage space than file/directory backup
D) Both A and C

Accepted Answer

Image backup is attractive because it requires minimal additional work to restore a fully functioning PC, allowing for a quick and comprehensive restoration process.

Question 2

With image backup, even if the entire hard drive is lost, its content can be restored onto the same machine or a different machine.

Accepted Answer

Image backup creates a complete copy of the hard drive, including all the files, folders, settings, and operating system. This copy can be used to restore the entire system onto the same machine or a different machine, in case of data loss or system failure. Therefore, even if the entire hard drive is lost, the content can be restored from the image backup.

Question 3

Properly hardened hosts and securely coded applications can help protect data while it is processed.

Accepted Answer

Hardened hosts and securely coded applications can help protect data during processing by implementing security measures such as access controls, encryption, and error handling. This can reduce the risk of data breaches, unauthorized access, and other security threats.

Question 4

Properly hardened hosts and securely coded applications can help protect data while it is transmitted.

Accepted Answer

Properly hardened hosts and securely coded applications primarily protect data at rest and during processing, while data in transit protection relies on encryption protocols and secure transmission methods.

Question 5

Data is the principal element of any information system.

Accepted Answer

Data is the raw material that is processed by an information system to produce meaningful information. Without data, there can be no information system.

Question 6

Typically, the shadow storage space is nearly unlimited.

Accepted Answer

Shadow storage space, used for system restore points and backups, is not nearly unlimited; it has a predefined limit that can be adjusted but can fill up, requiring management and cleanup.

Question 7

File/directory data backup copies ________.
A) programs
B) data
C) registry settings
D) Both A and B.

Accepted Answer

File/directory data backup copies are primarily concerned with duplicating data to prevent loss in case of a hardware failure, data corruption, or accidental deletion. Programs and registry settings are not typically the focus of such backups, although they can be included in a more comprehensive system backup.

Question 8

Using a secure cryptographic system can prevent attacks while data is being processed.

Accepted Answer

A secure cryptographic system can prevent attacks while data is being processed by encrypting the data so that it cannot be accessed or read by unauthorized parties. This can prevent attacks such as data breaches, man-in-the-middle attacks, and other forms of cyber threats. However, it is important to note that cryptographic systems must be properly implemented and maintained in order to be effective.

Question 9

File/directory backup is slower and takes up more storage space than image backup.

Accepted Answer

Image backup creates a complete snapshot of the entire system including the operating system, installed programs, settings, and files, which typically results in larger file sizes compared to file/directory backup that only copies selected files and folders.

Question 10

Typically, having enough shadow backup space for a few days is sufficient.

Accepted Answer

Having enough shadow backup space for a few days is usually sufficient as it allows for recent changes to be backed up and restored, in case of data loss or system failure. However, the specific backup requirements may vary based on the size and complexity of the system being backed up, as well as the organization's recovery time objectives.

Question 11

The process of keeping a backup copy of each file being worked on by backing it up every few minutes is called ________.
A) file backup
B) file/folder backup
C) image backup
D) shadowing

Accepted Answer

The process described in the question is called shadowing, which involves creating a backup of each file being worked on at regular intervals. Options A and B are too general and do not specifically describe the process being asked about. Option C refers to creating a backup copy of an entire system or device, rather than individual files.

Question 12

Normally, there is no limit on how long shadowing may maintain backed up files.

Accepted Answer

Shadowing or backup systems often have policies or settings that limit how long backups are retained, based on storage capacity, cost, and data management policies.

Question 13

Properly backed up data includes ________.
A) ensuring that copies of data files are stored safely and secured
B) ensuring that copies of data files will survive even if the data on the host are lost and damaged
C) Both A and B
D) Neither A nor B

Accepted Answer

Properly backed up data includes both ensuring that copies of data files are stored safely and secured and ensuring that copies of data files will survive even if the data on the host are lost and damaged. It is important to have multiple copies of important data to avoid loss in case of accidents or system failures.

Question 14

Companies usually conduct full backups on a ________ basis.
A) hourly
B) daily
C) weekly
D) monthly

Accepted Answer

Companies typically conduct full backups on a weekly basis to ensure data is regularly and comprehensively saved while balancing resource use and time constraints.

Question 15

Using a secure cryptographic system can prevent attacks while data is being transmitted.

Accepted Answer

A secure cryptographic system can ensure that the data being transmitted is encrypted and only accessible by the intended recipient, making it difficult for attackers to intercept or tamper with the data.

Question 16

Image backup is a fast form of backups.

Accepted Answer

Image backups, which capture a complete snapshot of a system at a specific point in time, can be slower than other types of backups like incremental or differential backups because they involve copying all data, not just changes.

Question 17

File/directory data backup copies data, programs, configurations, and registry settings.

Accepted Answer

The answer of File/directory data backup copies data, programs, configurations,...

Question 18

________ allows for very recent file changes to be restored.
A) Shadowing
B) File backup
C) File/folder backup
D) Image backup

Accepted Answer

Shadowing involves creating and storing multiple versions of a file, allowing for very recent file changes to be restored. This is different from traditional file backups, which may only capture changes made at certain intervals or times. File/folder backup and image backup also allow for restoring previous versions of files, but may not be as granular as shadowing when it comes to recent changes.

Question 19

Another name for data is raw facts.

Accepted Answer

Data refers to the raw facts and figures that are collected and stored for further analysis and interpretation.

Question 20

Data can be lost by ________.
A) mechanical failure
B) environmental casualties
C) malware
D) All of the above

Accepted Answer

All of the options mentioned can lead to data loss. Mechanical failure of storage devices, environmental casualties such as floods, fires, and earthquakes can damage computers and lead to data loss. Malware such as viruses, Trojans, and ransomware can also corrupt files or delete them entirely, leading to data loss. Therefore, the best choice is D, all of the above.
