What does RAID stand for?

Rapid Access Information Disks
Remote Area Indexed Disks
Redundant Array of Inexpensive disks
Read and Insert Data

Correct Answer

A. Redundant Array of Inexpensive disks

Explanation

RAID stands for Redundant Array of Inexpensive disks. This is a technology used in computer storage systems to improve data reliability and increase performance. It involves combining multiple physical disk drives into a single logical unit, providing redundancy and distributing data across the drives. This redundancy allows for data to be recovered in case of a disk failure, ensuring data integrity and preventing data loss. The term "Inexpensive" refers to the fact that RAID systems are typically more cost-effective compared to using single, high-capacity drives.

Where would be an appropriate place to store a companies DAT tapes after backup?

In a car
In the Network office
In a fire retardant safe - off site
In the managers desk

Correct Answer

A. In a fire retardant safe - off site

Explanation

Storing a company's DAT tapes in a fire retardant safe off-site is an appropriate choice for backup storage. This ensures that the tapes are protected from potential fire hazards and are stored in a secure location away from the main office. Off-site storage also provides an additional layer of protection against theft or damage that could occur on the company premises.

A shop wishes to implement a new backup system. Which of the following factors will affect which storage device is used for the backups?

The volume that needs to be backed up
What time of night the backups will begin
How much money the shop takes in a day
What security system the shop have in place

Correct Answer

A. The volume that needs to be backed up

Explanation

The volume that needs to be backed up will affect which storage device is used for the backups. This is because the size of the data to be backed up will determine the capacity requirements of the storage device. A larger volume of data will require a storage device with a higher capacity, such as a large hard drive or a network-attached storage (NAS) system. On the other hand, a smaller volume of data may be adequately backed up using a smaller storage device, such as a USB drive or a cloud storage service.

For a large company that has a large information system which TWO factors will be most important when devising a backup strategy?

How many PCs the company has
How will the backups be tested and who will do this
How often the data on the system changes - how often the backups need to be done
The network managers experience

Correct Answer

A. How will the backups be tested and who will do this

Explanation

Why is it important to perform a back up often e.g. every day rather than every month?

Why is it important to perform a back up often e.g. every day rather than every month?

It will make the system crash
It will cost more to back up monthly
The more time that there is between backups, the more you have to loose
Backing up often means that you can miss a backup and not worry

Correct Answer

A. The more time that there is between backups, the more you have to loose

Explanation

Performing a backup often, such as every day, is important because the more time that passes between backups, the more data you have at risk of being lost. If backups are only done monthly, for example, any changes or updates made to the system within that month would not be saved in the backup. This increases the chances of losing important data in the event of a system crash or failure. Regular backups help ensure that the most up-to-date information is protected and can be easily restored if needed.

What does DAT stand for?

Digital Analogue Track
Doesn’t Always Transmit
Digital Audio Tape
Data And Tracks

Correct Answer

A. Digital Audio Tape

Explanation

The acronym DAT stands for Digital Audio Tape. This technology was introduced in the late 1980s as a digital recording and playback medium for audio. DAT tapes provided a higher quality sound compared to analog cassette tapes. They were widely used in professional audio recording and mastering studios. DAT tapes were capable of storing audio data in a digital format, allowing for better fidelity and easier editing and manipulation of the recordings. However, with the advancement of digital technology, DAT tapes became less popular and were eventually replaced by other digital storage formats.

Type of backup storage in which data is read in a sequence is classified as

Storage access
Permanent access
Direct access
Serial access

Correct Answer

A. Serial access

Explanation

Serial access refers to a type of backup storage where data is read in a sequential manner. In this method, data is accessed one after the other, starting from the beginning and continuing until the desired data is reached. This is different from direct access, where data can be accessed randomly. Serial access is commonly used in tape drives and other sequential storage devices, as it allows for efficient and organized retrieval of data.

Type of storage disc which has magnetized directions to represent 1 or 0 is said to be

Bubble memory
Direct memory
Indirect Memory
Serial memory

Correct Answer

A. Bubble memory

Explanation

Bubble memory is a type of storage disc that uses magnetized directions to represent 1 or 0. It is a non-volatile memory technology that stores data in small magnetic bubbles within a solid-state material. These bubbles can be magnetized in different directions to represent binary data. Bubble memory was popular in the 1970s and 1980s for its high storage density and durability. However, it eventually became obsolete due to the development of more advanced and cost-effective storage technologies.

Discs that stores data more effectively against dirt and on a given area of the disc are known as

Exchangeable discs
Non exchangeable discs
Timed discs
Bubble discs

Correct Answer

A. Non exchangeable discs

Explanation

Non exchangeable discs are discs that are designed to store data more effectively against dirt and on a given area of the disc. Unlike exchangeable discs, which can be removed and replaced, non exchangeable discs are fixed and cannot be easily swapped out. This makes them more secure and less prone to damage or data loss. Timed discs and bubble discs are not relevant to the concept of data storage effectiveness, so they can be eliminated as options.
