CPHIMS Technology and IT Infrastructure Flashcards

Which network topology provides the highest redundancy by connecting every node directly to every other node?

Answer: Mesh topology

Mesh topology connects every node to every other node, providing maximum redundancy and fault tolerance.

A healthcare organization wants to ensure its EHR data remains available even during a server failure. Which technology BEST achieves this?

Answer: High-availability clustering

High-availability clustering automatically fails over to a standby server, minimizing downtime during hardware failures.

What is the primary purpose of a demilitarized zone (DMZ) in healthcare network architecture?

Answer: To host public-facing services while protecting internal networks

A DMZ hosts internet-facing services (like patient portals) while keeping the internal network protected from direct external access.

Which virtualization concept allows multiple isolated operating system instances to run on a single physical server?

Answer: Hypervisor-based virtualization

A hypervisor creates and manages multiple virtual machines, each running its own OS on shared physical hardware.

A hospital's RPO is set at 4 hours. What does this mean for their backup strategy?

Answer: No more than 4 hours of data can be lost in a disaster

Recovery Point Objective (RPO) defines the maximum acceptable data loss, meaning backups must capture data at least every 4 hours.

Which protocol is used to synchronize clocks across networked devices in a healthcare IT environment?

Answer: NTP

Network Time Protocol (NTP) synchronizes clocks across networked devices, which is critical for accurate audit logs and timestamps in healthcare.

What is the main advantage of software-defined networking (SDN) in a healthcare environment?

Answer: Centralizes network control for faster policy changes and management

SDN separates the control plane from the data plane, allowing centralized, programmable network management and rapid policy updates.
