CPHIMS CPHIMS Technology and IT Infrastructure 3 — Questions and Answers
Question 1: Which cloud deployment model is MOST appropriate for a health system that requires strict data control but wants to share infrastructure costs across its affiliated hospitals?
- Public cloud
- Private cloud
- Community cloud (Correct answer)
- Hybrid cloud
Correct answer: Community cloud
A community cloud is shared among organizations with similar requirements (e.g., healthcare affiliates) and balances cost-sharing with data control.
Question 2: A CPHIMS candidate is evaluating storage solutions. Which technology provides the lowest latency for database transactions in a clinical environment?
- Tape storage arrays
- Network-attached storage (NAS)
- Solid-state drive (SSD) storage (Correct answer)
- Cloud object storage
Correct answer: Solid-state drive (SSD) storage
SSDs use flash memory with no moving parts, providing significantly lower latency than spinning disk or tape for database transactions.
Question 3: What does the term 'latency' refer to in healthcare network performance monitoring?
- The total amount of data transferred per second
- The delay between sending and receiving data packets (Correct answer)
- The number of simultaneous connections supported
- The percentage of time a network is operational
Correct answer: The delay between sending and receiving data packets
Latency is the time delay between data transmission and receipt, which directly impacts performance of real-time clinical applications.
Question 4: A hospital implements a load balancer in front of its patient portal. What is the primary benefit?
- Encrypts data between the portal and database
- Distributes incoming traffic across multiple servers to prevent overload (Correct answer)
- Authenticates users before granting access
- Backs up portal data in real time
Correct answer: Distributes incoming traffic across multiple servers to prevent overload
Load balancers distribute client requests across multiple backend servers, improving availability and preventing any single server from being overwhelmed.
Question 5: Which IEEE standard defines wireless LAN (Wi-Fi) communication most commonly used in modern healthcare facilities?
- IEEE 802.3
- IEEE 802.11 (Correct answer)
- IEEE 802.1Q
- IEEE 802.15
Correct answer: IEEE 802.11
IEEE 802.11 defines the Wi-Fi standards (including 802.11ac/ax) used for wireless networking in healthcare environments.
Question 6: When a healthcare organization migrates from on-premises servers to IaaS, what infrastructure component remains the organization's responsibility?
- Physical server hardware
- Hypervisor management
- Operating system and application stack (Correct answer)
- Data center cooling and power
Correct answer: Operating system and application stack
In IaaS, the provider manages physical infrastructure and hypervisor; the customer manages OS, middleware, and applications.
Question 7: Which concept describes the ability of a healthcare IT system to increase capacity by adding more servers rather than upgrading existing ones?
- Vertical scaling
- Horizontal scaling (Correct answer)
- Elastic provisioning
- Load balancing
Correct answer: Horizontal scaling
Horizontal scaling (scale-out) adds more servers to distribute load, whereas vertical scaling upgrades the existing server's resources.
