Refer to the exhibit. An SAP administrator runs the AWS CLI command to retrieve the DatabaseConnections metric for an RDS for SAP ASE instance. The output shows a Sum statistic over 5-minute periods. What is the average number of connections per minute during this hour?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

10

The Sum statistic over each 5-minute period is the total number of connections during that period. To get average per minute, divide each sum by 5. However, the question asks for the average number of connections per minute over the entire hour. The sum of all datapoints is 45+48+52+50+47+49+51+53+50+48+52 = 545. There are 11 datapoints, each covering 5 minutes, so total minutes = 11*5 = 55 minutes (but actually from 00:05 to 00:55 inclusive, that's 11 periods * 5 = 55 minutes). The total connections sum = 545. Average connections per minute = 545 / 55 ≈ 9.9. But the options are whole numbers: 10, 50, 52, 545. 10 is closest. Correct answer is 10.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • 545

    Why it's wrong here

    545 is the total sum over the hour, not per minute.

  • 10

    Why this is correct

    Total connections sum = 545, total minutes = 55, average = 9.9 ≈ 10.

  • 50

    Why it's wrong here

    50 is the approximate average per 5-minute period, not per minute.

  • 52

    Why it's wrong here

    52 is a single datapoint sum, not the per-minute average.
