CPHIMS Technology and IT Infrastructure Flashcards

A large, multi-site hospital system is looking to consolidate its IT resources, improve scalability, and reduce capital expenditures on hardware. They want to retain control over their operating systems and applications but offload the management of servers, storage, and networking. Which cloud computing model best fits their needs?

Answer: Infrastructure as a Service (IaaS)

Infrastructure as a Service (IaaS) provides virtualized computing resources over the internet, including servers, storage, and networking. The client retains control over the operating systems, middleware, and applications, while the provider manages the underlying hardware infrastructure. This model allows the hospital system to reduce capital expenses and scale resources as needed, which aligns perfectly with their stated goals.

A healthcare organization is implementing a new cybersecurity strategy. Which of the following practices represents a proactive approach to enhancing security by limiting the potential spread of a breach?

Answer: Implementing network segmentation.

Network segmentation is the practice of dividing a computer network into smaller, isolated subnetworks or segments. This practice contains threats within a compromised segment, preventing them from moving laterally to other parts of the network. This is a crucial proactive security measure in healthcare to protect critical systems, like medical devices and EHR databases, from being affected by a breach in a less secure area, such as guest Wi-Fi.

Which interoperability standard is specifically designed to use modern web technologies, such as RESTful APIs, to exchange healthcare information and is composed of modular components called 'Resources'?

Answer: Fast Healthcare Interoperability Resources (FHIR)

Fast Healthcare Interoperability Resources (FHIR) is a modern standard from HL7 designed for exchanging electronic health information. It leverages web standards, including RESTful APIs and JSON/XML formats, making it easier for developers to create applications that can integrate with different EHRs. Its fundamental building blocks are 'Resources,' which are modular components representing specific clinical or administrative concepts.

A critical server hosting the hospital's Electronic Health Record (EHR) system fails unexpectedly. The IT department immediately switches to a secondary, identical server at a different location with a replicated, up-to-the-minute database. This process is an example of:

Answer: Failover

Failover is a method of protecting computer systems from failure, in which standby equipment automatically takes over when the main system fails. In this scenario, the seamless switch to a redundant, secondary server is a classic example of a failover process, which is a key component of a high-availability and disaster recovery strategy.

As part of its HIPAA-mandated contingency plan, a healthcare clinic must regularly test its ability to recover data and resume operations after a simulated disaster. What is the PRIMARY purpose of this requirement?

Answer: To validate the effectiveness of the disaster recovery plan and identify gaps.

The primary purpose of regularly testing a disaster recovery plan is to ensure it is effective and will work as intended during an actual emergency. Testing validates procedures, recovery time objectives (RTOs), and the integrity of backed-up data, allowing the organization to identify and address any weaknesses or gaps before a real disaster strikes.

A healthcare analytics firm subscribes to a cloud service that provides a complete, ready-to-use electronic health record (EHR) application, including all updates, maintenance, and infrastructure management. Users access the EHR through a web browser. This cloud service model is best described as:

Answer: Software as a Service (SaaS)

Software as a Service (SaaS) is a cloud computing model where a third-party provider hosts applications and makes them available to customers over the Internet. The provider manages the entire technology stack, including the application, data, runtime, middleware, and servers. The user simply accesses the ready-to-use software, typically through a web browser. An EHR provided in this manner is a prime example of a SaaS offering.
