Question 1

Which term describes the act of keeping a complete copy of the archive in another remote location?

Accepted Answer

Disaster recovery involves strategies and actions to protect and recover critical IT infrastructure and data in the event of a disaster. Keeping complete copies of archives in remote locations is a key component of disaster recovery planning to ensure data can be restored after catastrophic events.

Question 2

In which RAID level are all data and error corrections (parity)striped across all connected disks?

Accepted Answer

RAID 5 uses striping with parity, meaning that data and parity information are distributed across all the drives in the array. This allows for both improved performance and data redundancy.

Question 3

Which term is used to describe when data are broken up into pieces and each disk receives a "piece" of the data?

Accepted Answer

Striping is the process where data is split into blocks and spread across multiple storage devices, such as disks, allowing for faster data access and performance.

Question 4

What term is used to describe a database that is running two identical databases simultaneously?

Accepted Answer

The term "mirrored" is used to describe a database configuration where two identical databases are running simultaneously for purposes of redundancy and fault tolerance. This ensures that if one database fails, the other can take over without loss of data or service interruption.

Question 5

Most of the ___ levels of RAID are a combination of the original five.

Accepted Answer

RAID levels 10, 50, and 60 are combinations of the original five RAID levels.

Question 6

In which RAID level are all data mirrored on two disks?

Accepted Answer

RAID 1 is known for mirroring all data on two disks, providing redundancy by duplicating the same data on two drives.

Question 7

A database that keeps track of how the images are related and provides search capability is a(n)

Accepted Answer

An image manager is a type of database specifically designed to keep track of images, their relationships, and provides search capabilities to efficiently manage and retrieve images.

Question 8

Which term describes the technology that allows a film to be digitized and then analyzed by a computer to alert the radiologist of possible questionable areas on a radiograph?

Accepted Answer

CAD, which stands for Computer-Aided Detection, is the technology that enables the digitization of films for analysis by computers, which can then highlight potential areas of concern for further review by a radiologist.

Question 9

The acronym for RAID is redundant

Accepted Answer

RAID stands for both "Redundant Array of Inexpensive Disks" and "Redundant Array of Independent Disks." The terminology has evolved over time, with "inexpensive" being used in the past and "independent" being more commonly used now.

Question 10

Which device scans an analog film and produces numeric signals based on the appearance of the film?

Accepted Answer

A film digitizer is specifically designed to scan analog film and convert the images into digital signals, allowing the images to be stored, viewed, and manipulated on computers.

Question 11

The place where records or documents are preserved for historic purposes is the

Accepted Answer

Archives are specifically designed for the preservation of historical documents and records, serving as a repository for such materials.

Question 12

Which term is used to describe the process of transferring images to remote locations for reading by a radiologist?

Accepted Answer

Teleradiology is the term used to describe the process of transferring medical images from one location to another for the purposes of sharing studies with other radiologists and physicians. This allows for radiological analysis and interpretation to be done remotely.

Question 13

Any supplemental device connected to a PACS that performs a specific function is known as a(n)

Accepted Answer

Peripherals are supplemental devices connected to a system (in this case, a Picture Archiving and Communication System or PACS) that perform specific functions, such as printers, scanners, or additional monitors, enhancing the system's capabilities beyond its core functions.

Question 14

A level,layer,or division of something is known as a

Accepted Answer

A tier is a term used to describe a level, layer, or division within a structure or system, fitting the definition provided.

Question 15

Which of the following is an archive storage configuration that links different kinds of data storage devices on a special-purpose network?

Accepted Answer

SAN (Storage Area Network) is specifically designed to connect different types of data storage devices (like disk arrays, tape libraries, and optical jukeboxes) with servers on a special-purpose high-speed network.

Question 16

Which picture archival and communication system (PACS)component interfaces with the radiology information system and hospital information system?

Accepted Answer

The Image Manager in a PACS system interfaces with the Radiology Information System (RIS) and Hospital Information System (HIS) to manage and distribute patient imaging data and related information.

Question 17

A category of disk drives that uses two or more drives in combination for fault tolerance and performance is

Accepted Answer

RAID (Redundant Array of Independent Disks) is a technology that combines multiple disk drives into a single logical unit for the purposes of data redundancy, performance improvement, or both.

Question 18

Which of the following is an archive storage configuration that has RAID arrays directly attached to the network?

Accepted Answer

NAS (Network Attached Storage) is the correct answer because it refers to storage devices that are connected directly to a network, allowing multiple users and heterogeneous client devices to retrieve data from centralized disk capacity. Users on a local area network (LAN) access the shared storage via a standard Ethernet connection. RAID arrays can be part of a NAS to provide redundancy and performance improvements. SAN (Storage Area Network) and DAS (Direct Attached Storage) do not fit the description as SAN is a network of storage devices not directly attached to the network, and DAS is directly attached to a computer and not accessible over a network.

Question 19

In which RAID level are all data striped across all connected disks and error correction (parity)is contained on one disk?

Accepted Answer

RAID 3 stripes data across all but one of the disks in the array, with the remaining disk being used to store parity information for error correction. This allows for improved performance and data protection.

Question 20

Which component of the archive consists of the physical storage devices?

Accepted Answer

The archive server and image storage are both physical storage devices.
