Which statement about ISS viewable data is true?

• A. You can view the last PED only
• B. You can view the last three PEDs and the last 24 months
• C. You can view all PEDs and all months
• D. You can view 12 months only

Answer: (B)

ISS viewable data is designed to provide a focused, useful window of information rather than the full history. The system allows you to view the last three PEDs plus a rolling 24-month period. This setup gives quick access to the most recent adjustments while still offering enough historical context for trend analysis over two years. It avoids the impracticality of displaying every PED ever recorded and keeps data retrieval fast. The other options don’t fit because viewing only the last PED misses recent activity and comparisons; claiming all PEDs and all months would be unnecessary and inefficient for normal use; and limiting to 12 months would reduce the historical window below the standard 24 months.
