CPHIMS CPHIMS Technology and IT Infrastructure 2 — Questions and Answers
Question 1: Which network topology provides the highest redundancy by connecting every node directly to every other node?
- Star topology
- Bus topology
- Mesh topology (Correct answer)
- Ring topology
Correct answer: Mesh topology
Mesh topology connects every node to every other node, providing maximum redundancy and fault tolerance.
Question 2: A healthcare organization wants to ensure its EHR data remains available even during a server failure. Which technology BEST achieves this?
- RAID 0 striping
- Single-server backup tapes
- High-availability clustering (Correct answer)
- Manual failover procedures
Correct answer: High-availability clustering
High-availability clustering automatically fails over to a standby server, minimizing downtime during hardware failures.
Question 3: What is the primary purpose of a demilitarized zone (DMZ) in healthcare network architecture?
- To store patient PHI securely
- To host public-facing services while protecting internal networks (Correct answer)
- To provide wireless access for clinical staff
- To segment administrative from clinical systems
Correct 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.
Question 4: Which virtualization concept allows multiple isolated operating system instances to run on a single physical server?
- Load balancing
- Containerization only
- Hypervisor-based virtualization (Correct answer)
- Network address translation
Correct answer: Hypervisor-based virtualization
A hypervisor creates and manages multiple virtual machines, each running its own OS on shared physical hardware.
Question 5: A hospital's RPO is set at 4 hours. What does this mean for their backup strategy?
- Systems must be restored within 4 hours of a failure
- No more than 4 hours of data can be lost in a disaster (Correct answer)
- Backups must run every 4 hours at minimum
- Staff must be notified within 4 hours of an outage
Correct 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.
Question 6: Which protocol is used to synchronize clocks across networked devices in a healthcare IT environment?
- SNMP
- NTP (Correct answer)
- LDAP
- DHCP
Correct answer: NTP
Network Time Protocol (NTP) synchronizes clocks across networked devices, which is critical for accurate audit logs and timestamps in healthcare.
Question 7: What is the main advantage of software-defined networking (SDN) in a healthcare environment?
- Eliminates the need for physical network hardware
- Centralizes network control for faster policy changes and management (Correct answer)
- Automatically encrypts all patient data in transit
- Replaces the need for firewalls and IDS systems
Correct 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.
