CIIP - Certified Imaging Informatics Professional Information Technology Fundamentals Questions and Answers

Question 1

The DICOM standard specifies protocols for communication between medical imaging devices.
At which layer of the Open Systems Interconnection (OSI) model does the DICOM Upper Layer Protocol primarily operate?

Accepted Answer

Application Layer

Answer

Physical Layer

Answer

Data Link Layer

Answer

Transport Layer

Question 2

An imaging informatics administrator is configuring a new storage array for a PACS short-term cache, where both fast read/write performance and protection against a single disk failure are critical requirements. Which RAID configuration BEST meets these needs?

Accepted Answer

RAID 10 (Stripe of Mirrors)

Answer

RAID 0 (Striping)

Answer

RAID 1 (Mirroring)

Answer

RAID 5 (Striping with Parity)

Question 3

A radiologist reports that searching for a patient's prior exams in the PACS is consistently slow. An analysis of the PACS database reveals that the query is performing a full table scan. Which of the following database optimizations would MOST likely resolve this performance issue?

Accepted Answer

Creating an index on the patient ID and study date columns

Answer

Increasing the server's RAM

Answer

Defragmenting the storage volume

Answer

Archiving older studies to near-line storage

Question 4

A teleradiology service needs to receive patient imaging studies from a partner hospital over the public internet. Which of the following is the MOST secure method to ensure the confidentiality and integrity of the DICOM data during transmission?

Accepted Answer

Encapsulating the DICOM traffic within a Virtual Private Network (VPN) tunnel

Answer

Transmitting data using the standard DICOM protocol over a dedicated port

Answer

Compressing the images with lossless JPEG before sending

Answer

Restricting access by the source firewall's static IP address

Question 5

An imaging department's server room contains multiple aging, physical servers, each dedicated to a single application (e.g., RIS broker, DICOM router, HL7 interface engine). To reduce hardware costs, power consumption, and administrative overhead, the IT department wants to consolidate these applications onto a single, more powerful physical server. Which technology enables this consolidation?

Accepted Answer

Server virtualization

Answer

Load balancing

Answer

Network-attached storage (NAS)

Answer

RAID configuration

Question 6

A CT scanner technologist reports they can no longer send images to the PACS server. An informatics specialist uses the `ping` command from the CT scanner's console and receives a successful reply from the PACS server's IP address. What can be concluded from this test result?

Accepted Answer

Basic IP network connectivity exists between the scanner and the server.

Answer

The PACS application is functioning correctly and accepting studies.

Answer

The physical network cable for the CT scanner is faulty.

Answer

The DICOM configuration (AET, Port) on the scanner is correct.
