QA evaluates all core base voice/video/data transport and transmission systems at what interval?

• A. Every 12 months
• B. Every 18 months
• C. Every 24 months
• D. Every 36 months

Answer: (B)

Regular, scheduled QA evaluations of all base voice, video, and data transport and transmission systems ensure ongoing reliability, performance, and interoperability as upgrades and changes occur. The interval of every 18 months provides a practical cadence that catches issues and validates compatibility without overburdening resources. It aligns with typical hardware refresh cycles and software update timelines, allowing testing of new configurations and integration paths before problems affect operations. A yearly check can be too resource-intensive given the breadth of systems; waiting two years may let drift and obsolescence accumulate; waiting three years increases risk of unresolved vulnerabilities and incompatibilities. This mid-range cadence helps maintain confidence in the system’s readiness and resilience.
