Which component is lost with Ram Dump?

• A. DCGAP (not +2)
• B. MDP
• C. Navaid Identification
• D. Audio tones

Answer: (A)

A RAM dump wipes all volatile memory, so any data that only exists while the system is running and is stored in RAM will be lost. DCGAP represents a dynamic, runtime parameter kept in RAM during operation, so when RAM is dumped, this value disappears. In contrast, Navaid Identification and Audio tones are tied to the nav/audio subsystems' non-volatile storage or dedicated hardware—firmware, ROM/Flash, or ASIC resources—so they persist after a RAM dump. MDP is similarly associated with persistent or hardware-backed data, not just transient RAM content. Therefore, the component lost with a RAM dump is the runtime, RAM-resident DCGAP.
