Question 1

You want a storage medium that allows you to locate a particular data item immediately, without having to move consecutively through items stored in front of the desired data item or file. What kind of access will this storage medium use?

Accepted Answer

Direct access allows you to locate and retrieve a specific data item immediately without having to go through other items sequentially.

Question 2

Which of the following is not true about tape storage?

Accepted Answer

The statement "A benefit of tape is that it allows for nonsequential access" is actually true. Therefore, the option that is not true is D.

Question 3

You are looking to implement a high-speed network with the sole purpose of providing storage to other attached servers. Which of the following will you implement?

Accepted Answer

A Storage Area Network (SAN) is specifically designed to provide high-speed storage to servers. SCSI and EIDE are both types of hard drive interfaces, and eSATA is a type of external hard drive connection. While these may offer good speeds, they are not designed specifically for server storage and may not provide the same level of performance or manageability as a SAN.

Question 4

You are looking for a backup that copies only the files that have changes since the last full backup. Which of the following will you use?

Accepted Answer

Incremental backup copies only the files that have changed since the last backup, whether it was a full backup or an incremental backup. It is more efficient and takes less time and storage space compared to a full or differential backup.

Question 5

What does NAS stand for?

Accepted Answer

NAS stands for Network Attached Storage, which is a type of file storage technology that allows multiple users and devices to access the same set of files over a network. Unlike traditional storage solutions, NAS systems typically have their own operating systems, processors, and network interfaces, making them more efficient and flexible than basic file servers or external hard drives.

Question 6

What is the simplest RAID storage design?

Accepted Answer

Mirroring or RAID 1 is the simplest RAID storage design. It involves creating an exact copy (mirror) of data on two separate drives, so if one drive fails, the other can still function as the primary drive without any data loss. This design is easy to set up and doesn't require any special hardware or software.

Question 7

Which RAID level technique splits data, instructions, and information across multiple disks in the array?

Accepted Answer

Striping is a RAID level technique that splits data, instructions, and information across multiple disks in the array. This allows for faster performance and better fault tolerance as data can be read and written in parallel across the drives. Differentiation and archiving are not RAID level techniques, and mirroring involves duplicating data on multiple drives rather than splitting it across them.

Question 8

What kind of controller uses serial signals to transfer data, instructions, and information?

Accepted Answer

SATA (Serial ATA) uses serial signals to transfer data, instructions, and information.

Question 9

Which of the following is a type of backup you can only perform at your large enterprise?

Accepted Answer

Continuous backup requires high-bandwidth connection and significant resources, which are typically available only in large enterprises. The other types of backups (full, differential, incremental) can be performed at smaller organizations as well.

Question 10

Which of the following statements is NOT true about smart cards?

Accepted Answer

Contactless smart cards do not communicate with a reader using Bluetooth technology. They use radio frequency identification (RFID) or near-field communication (NFC) to communicate wirelessly with a reader.

Question 11

Which of the following has a higher capacity and better quality than standard DVDs, especially for high-definition audio and video?

Accepted Answer

Blu-ray Discs have a higher capacity (up to 50 GB for a dual-layer disc) and better quality than standard DVDs, particularly for high-definition audio and video. They use a blue-violet laser to read and write data, which allows for a more precise reading of information stored on the disc.

Question 12

What does a controller control?

Accepted Answer

A controller controls the interface between the hard disk and the system bus, managing data transfer and communication.

Question 13

Which term is used to describe large businesses that require special hardware geared for heavy use, and maximum availability and efficiency to fit the needs of their hundreds or thousands of workers?

Accepted Answer

The term "enterprise" is commonly used to describe large businesses that require special hardware geared for heavy use, maximum availability, and efficiency to fit the needs of their hundreds or thousands of workers. The term "global giant" is often used to refer to large multinational corporations, while "power player" and "high-traffic" are not commonly used to describe this type of business.

Question 14

A popular use of CD-RW and CD-R discs is to create audio CDs. What is the process of copying audio and/or video data from a purchased disc and saving it on digital media called?

Accepted Answer

The process of copying audio and/or video data from a purchased disc and save it on digital media is called ripping. This involves using software to extract the audio or video data from the disc and convert it into a digital file format that can be saved on a CD-RW or CD-R disc. Once saved, the digital files can be played back using a CD or DVD player or transferred to other devices such as a computer, smartphone, or tablet.

Question 15

Which of the following will you use if you are looking to perform backups in between full backups?

Accepted Answer

Differential backup is a type of backup that only backs up the data that has changed since the last full backup, making it efficient and quicker than a full backup. It is commonly used to perform backups in between full backups. Archival backup, selective backup, and partial backup are types of backups that do not necessarily involve backing up only the changed data and may not be suitable for performing backups in between full backups.

Question 16

Your company has elected to offload all storage management to an outside organization. What is the term for this?

Accepted Answer

The term for offloading storage management to an outside organization is outsourcing.

Question 17

You are looking for an RFID tag that does not contain a battery because you want one that is small enough to be embedded in skin. Which of the following will you use?

Accepted Answer

Passive RFID tags do not contain batteries and instead rely on the energy from the RFID reader to power their operation. This makes them small enough to be embedded in skin while still functioning effectively. Additionally, active RFID tags require a battery to operate and are typically larger in size. Contact RFID tags are meant to be physically touched to the reader, and embedded RFID tags are not a specific type of RFID tag but rather refer to any tag that has been placed within an object or material.

Question 18

You are looking for the best protection against data loss. Which of the following will you use?

Accepted Answer

Archival backup provides the best protection against data loss as it creates a complete backup of all data and stores it in a separate location, ensuring that data can be recovered in the event of a disaster or system failure. Differential backup, selective backup, and partial backup only back up certain portions of data and may not provide comprehensive protection against data loss.

Question 19

You are looking for a way to choose specific files to back up, regardless of whether or not the files have changed since the last incremental backup. Which of the following will you use?

Accepted Answer

A selective backup allows you to choose specific files to back up, regardless of whether or not they have changed since the last backup. This is preferred over a full backup because it saves storage space and time. Archival backup and differential backup both involve backing up all files, with the former emphasizing on long term preservation and the latter only backing up files that have changed since the last full backup.

Question 20

You want a form of backup that copies all program and data files. Which of the following will you use?

Accepted Answer

An archival backup, also known as a full backup, copies all program and data files. This type of backup is the best choice for creating a complete and comprehensive backup of all important files, and is often performed on a regular basis to ensure data is adequately protected. The other options listed - differential backup, selective backup, and partial backup - are all types of backup strategies that do not copy all program and data files.
