💡 Hint

Common Mistakes

Using 80 instead of 0.8 causes errors because the system expects a decimal.

Using 8 or 1.2 are invalid percentages.

The budget alert threshold is a decimal representing the percentage. 0.8 means 80%.

Complete the code to create a cost optimization rule that stops idle compute instances after 30 minutes.

MLOps

optimization_rule = {'action': 'stop', 'condition': 'idle_time > [1]'}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 60 or 45 minutes delays stopping too long.

Using 15 minutes stops instances too early.

The rule stops instances after 30 minutes of idle time, so the condition must be 'idle_time > 30'.

Fix the error in the code to calculate monthly cost savings by multiplying hourly savings by hours in a month.

MLOps

monthly_savings = hourly_savings [1] 720

💡 Hint

Common Mistakes

Using + or - changes the meaning and causes wrong results.

Using / divides instead of multiplying.

To get monthly savings, multiply hourly savings by total hours (720) in a 30-day month.

Fill both blanks to create a dictionary comprehension that maps instance IDs to their cost if cost is greater than 100.

MLOps

costly_instances = {id: cost for id, cost in instances.items() if cost [1] [2]

Drag options to blanks, or click blank then click option'

A>

B100

C<

D50

💡 Hint

Common Mistakes

Using < or 50 filters the wrong instances.

Swapping the operator and value causes logic errors.

The comprehension filters instances with cost greater than 100, so use > and 100.

Fill all three blanks to create a dictionary of instance names in uppercase mapped to their usage hours, filtering only those with usage over 200 hours.

MLOps

filtered_usage = [1]: [2] for [3], usage in usage_data.items() if usage > 200

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'instance' instead of 'name' causes variable errors.

Not converting name to uppercase changes the key format.

Using wrong values for keys or values breaks the dictionary.

The dictionary keys are uppercase names, values are usage hours, and the loop variable is 'name'.
