Question
An architect is responsible for creating the design for a Cloud Monitoring solution that will be used to monitor a greenfield VMware Software-Defined Data Center (SDDC). During a requirements gathering workshop, the Service Owner provided a list of solution requirements:
- The solution must support a monthly availability target of 99.9%.
- The solution must support the monitoring of 1000 virtual machines
across two data center locations.
- The solution must support the retention of live data for at least 12
months.
- The solution must be redundant to a minimum of N + 1 including during
planned maintenance.
- The Recovery Time Objective (RTO) of solution is 4 hours.
Given the information from the Service Owner, which two statements would be considered functional requirements? (Choose two.)
Options
- AThe solution must support the monitoring of 1000 virtual machines across two data center
- BThe Recovery Time Objective (RTO) of solution is 4 hours.
- CThe solution must support a monthly availability target of 99.9%.
- DThe solution must be redundant to a minimum of N + 1 including during planned maintenance.
- EThe solution must support the retention of live data for at least 12 months.

Explanation
Functional requirements define what a system must do, while non-functional requirements define how well it does it (performance, reliability, resilience). Options A and E are correct because they describe specific capabilities the system must provide: A defines the monitoring function's scope (1000 VMs across two locations - a "what"), and E defines a data management function the system must perform (retain live data for 12 months - also a "what").
The distractors are wrong because they all describe quality attributes rather than functions: C (99.9% availability) and D (N+1 redundancy) are non-functional requirements about reliability and resilience, while B (RTO of 4 hours) is a non-functional requirement about recoverability - none of these describe a feature or behavior the system performs.
Memory tip: Ask yourself "Is this a feature or a quality?" Features (monitoring VMs, retaining data) = functional. Qualities (how available, how redundant, how fast to recover) = non-functional. The acronym FURPS+ can help - Functionality is separate from Usability, Reliability, Performance, and Supportability.
