Practice - 5 Tasks

1fill in blank

easy

Complete the code to specify the unit for Lambda memory pricing.

AWS

lambda_memory_price_per_[1] = 0.00001667

💡 Hint

Common Mistakes

Using hours instead of seconds

Using MB instead of GB

The Lambda pricing for memory is charged per GB-second, which means per gigabyte of memory used per second of execution.

2fill in blank

medium

Complete the code to calculate the total Lambda cost given memory in GB and duration in seconds.

AWS

total_cost = memory_in_[1] * duration_in_[2] * price_per_gb_second

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

💡 Hint

Common Mistakes

Mixing MB with GB

Using minutes instead of seconds

Memory must be in GB and duration in seconds to correctly calculate Lambda cost using the GB-second pricing model.

3fill in blank

hard

Fix the error in the Lambda cost calculation by choosing the correct unit for duration.

AWS

cost = memory_gb * duration_in_[1] * price_per_gb_second

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

💡 Hint

Common Mistakes

Using minutes or hours instead of seconds

Using milliseconds which is too granular

Lambda duration is billed in seconds, so duration must be in seconds for correct cost calculation.

4fill in blank

hard

Fill both blanks to complete the Lambda pricing formula for total cost.

AWS

total_cost = [1] * [2] * price_per_gb_second

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

💡 Hint

Common Mistakes

Using MB for memory

Using minutes for duration

The total cost is calculated by multiplying memory in GB by duration in seconds and the price per GB-second.

5fill in blank

hard

Fill all three blanks to complete the Lambda pricing calculation including request count.

AWS

total_cost = ([1] * [2] * price_per_gb_second) + ([3] * price_per_request)

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

Amemory_gb

Bduration_seconds

Crequest_count

Dduration_minutes

💡 Hint

Common Mistakes

Using minutes instead of seconds for duration

Confusing request count with duration

The total Lambda cost includes the compute cost (memory GB * duration seconds * price per GB-second) plus the request cost (number of requests * price per request).
