CMA Technology and Platform Analysis 3

Question 1

A master architect is designing a system that must detect and respond to fraud in under 100 milliseconds. Which processing architecture best fits this requirement?

Accepted Answer

Stream processing

Answer

Stream processing enables continuous, real-time analysis of data as it arrives, making sub-100ms fraud detection feasible.

Question 2

Which of the following best describes the concept of 'platform lock-in' risk in cloud technology selection?

Accepted Answer

The risk that proprietary services make migration to another vendor costly or difficult

Answer

Platform lock-in occurs when proprietary cloud services, APIs, or data formats make it technically or financially difficult to switch vendors.

Question 3

In a microservices platform, which pattern allows a service to maintain its own data store and prevents direct database sharing between services?

Accepted Answer

Database-per-service pattern

Answer

The database-per-service pattern ensures each microservice owns its data store, enabling independent deployment and technology choice.

Question 4

Which metric best measures the proportion of time a system is actually operational and available to users?

Accepted Answer

Availability percentage (uptime %)

Answer

Availability percentage (uptime %) directly measures the proportion of time a system is operational, expressed as a percentage of total time.

Question 5

A CMA is evaluating a containerization strategy. Which statement best describes the advantage of containers over traditional virtual machines?

Accepted Answer

Containers share the host OS kernel, making them lighter and faster to start

Answer

Containers share the host OS kernel rather than emulating full hardware, making them much lighter in resource usage and faster to start than VMs.
