Practice - 5 Tasks

1fill in blank

easy

Complete the code to specify the billing unit for Cloud Functions memory allocation.

GCP

memory: [1]

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

💡 Hint

Common Mistakes

Using a number without unit like '256'

Using incorrect units like GB or KB

The memory for Cloud Functions is specified in megabytes (MB), such as '256MB'.

2fill in blank

medium

Complete the code to set the maximum function execution time in seconds.

GCP

timeout: [1]

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

A300ms

B540s

C540

D5m

💡 Hint

Common Mistakes

Using only a number without unit

Using 'ms' or 'm' instead of 's'

The timeout for Cloud Functions is set in seconds with 's' suffix, e.g., '540s' for 9 minutes.

hard

Fix the error in the billing configuration by selecting the correct CPU allocation format.

GCP

cpu: [1]

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

A1000m

B1vCPU

C1cpu

D1

💡 Hint

Common Mistakes

Using '1' without units

Using '1vCPU' which is invalid

Using lowercase 'cpu' without 'm'

CPU allocation in Cloud Functions is specified in millicores, e.g., '1000m' means 1 full CPU.

4fill in blank

hard

Fill both blanks to correctly calculate the total billed GB-seconds for a function.

GCP

billed_gb_seconds = memory_in_gb [1] execution_time_seconds [2]

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

💡 Hint

Common Mistakes

Using division or subtraction instead of multiplication

Mixing operators incorrectly

The total billed GB-seconds is calculated by multiplying memory in GB by execution time in seconds, then adding any overhead if applicable.

5fill in blank

hard

Fill all three blanks to define a pricing formula for Cloud Functions including memory, CPU, and invocation count.

GCP

total_cost = (memory_gb [1] memory_rate) + (cpu_units [2] cpu_rate) + (invocations [3] invocation_rate)

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

💡 Hint

Common Mistakes

Using addition instead of multiplication for rates

Using division or subtraction incorrectly

The pricing formula multiplies each resource usage by its rate, then sums all costs.
