At 99.9% uptime, downtime is 0.1% of the year, so revenue at risk = $1,000,000 × 0.001 = $1,000. At 99.99% uptime, downtime is 0.01%, so revenue at risk = $1,000,000 × 0.0001 = $100.

Question
Your organization wants to increase the availability target of an application from 99.9% to 99.99% for an investment of $2,000. The application's current revenue is $1,000,000.

Explanation
The calculation compares the revenue at risk under each availability level. At 99.9% uptime, downtime is 0.1% of the year, so revenue at risk = $1,000,000 × 0.001 = $1,000. At 99.99% uptime, downtime is 0.01%, so revenue at risk = $1,000,000 × 0.0001 = $100. The value of the improvement is $1,000 − $100 = $900. Since the cost of the improvement ($2,000) exceeds the value gained ($900), the investment is not justified for a single year. Option A correctly states $900 and concludes it is not worth the investment.
