Practice - 5 Tasks

1fill in blank

easy

Complete the code to specify the budget amount in the configuration.

GCP

{
  "budget": {
    "amount": [1]
  }
}

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

A"1000"

B1000

CbudgetAmount

Damount

💡 Hint

Common Mistakes

Using quotes around the number, making it a string.

Using variable names instead of numeric values.

The budget amount should be a number without quotes to represent the value correctly.

Complete the code to set the threshold rule percentage for budget alerts.

GCP

{
  "thresholdRules": [
    {
      "thresholdPercent": [1]
    }
  ]
}

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

A0.5

B"50"

C50

D"0.5"

💡 Hint

Common Mistakes

Using strings instead of numbers.

Using whole numbers instead of decimals for percentages.

The thresholdPercent should be a decimal number representing the fraction of the budget (e.g., 0.5 for 50%).

Fix the error in the alert rule operator to correctly trigger when the budget is exceeded.

GCP

{
  "alertRule": {
    "operator": "[1]"
  }
}

DNOT_EQUALS

Attempts:

💡 Hint

Common Mistakes

Using LESS_THAN or EQUALS which do not trigger on overspending.

Using NOT_EQUALS which is not a valid operator here.

The operator should be GREATER_THAN to trigger alerts when spending exceeds the budget.

Fill both blanks to define the budget filter for projects and services.

GCP

{
  "budgetFilter": {
    "projects": ["[1]"],
    "services": ["[2]"]
  }
}

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

Aprojects/123456789

Bprojects/987654321

Cservices/compute.googleapis.com

Dservices/storage.googleapis.com

Attempts:

💡 Hint

Common Mistakes

Using only numeric IDs without the 'projects/' prefix.

Using service names without the 'services/' prefix.

The projects field requires the project ID in the format 'projects/ID'. The services field requires the service name like 'services/compute.googleapis.com'.

5fill in blank

hard

Fill all three blanks to configure notifications with a Pub/Sub topic and email recipients.

GCP

{
  "notificationsRule": {
    "pubsubTopic": "[1]",
    "schemaVersion": "[2]",
    "monitoringNotificationChannels": ["[3]"]
  }
}

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

Aprojects/my-project/topics/budget-alerts

B1.0

Cprojects/my-project/notificationChannels/1234567890

D2.0

Attempts:

3 left

💡 Hint

Common Mistakes

Using short names instead of full resource paths.

Using incorrect schema versions.

The pubsubTopic must be the full topic name. The schemaVersion is usually '1.0'. The monitoringNotificationChannels is the full notification channel resource name.

Practice

1. What is the primary purpose of setting a budget alert in Google Cloud Platform?

easy

A. To block all services when budget is exceeded

B. To automatically increase your budget limit

C. To notify you when your spending reaches a certain threshold

D. To create a backup of your billing data

Solution

1. Step 1: Understand budget alerts function

   Budget alerts are designed to notify users when spending approaches or exceeds set limits.

2. Step 2: Identify the correct purpose

   Among the options, only notification at spending thresholds matches the budget alert purpose.

3. Final Answer:

   To notify you when your spending reaches a certain threshold -> Option C

4. Quick Check:

   Budget alerts = notify spending threshold [OK]

Hint: Budget alerts notify spending limits, not block or increase budget [OK]

Common Mistakes:

• Thinking budget alerts block services automatically
• Assuming budget alerts increase budget limits
• Confusing budget alerts with data backup

2. Which of the following is the correct way to specify a budget threshold alert at 50% of the budget in a GCP budget configuration?

easy

A. "thresholdRules": [{"thresholdPercent": 50}]

B. "thresholdRules": [{"thresholdPercent": 0.5}]

C. "thresholdRules": [{"thresholdPercent": 1.5}]

D. "thresholdRules": [{"thresholdPercent": 5}]

Solution

1. Step 1: Understand thresholdPercent format

   In GCP budget config, thresholdPercent is a decimal representing the fraction of the budget (e.g., 0.5 for 50%).

2. Step 2: Match correct decimal for 50%

   0.5 equals 50%, so "thresholdRules": [{"thresholdPercent": 0.5}] is correct; 50 or 5 are invalid as they exceed 1.

3. Final Answer:

   "thresholdRules": [{"thresholdPercent": 0.5}] -> Option B

4. Quick Check:

   50% = 0.5 decimal [OK]

Hint: Use decimals (0.5) not whole numbers (50) for thresholdPercent [OK]

Common Mistakes:

• Using 50 instead of 0.5 for 50%
• Setting thresholdPercent greater than 1
• Confusing percentage with decimal format

3. Given this budget alert configuration snippet:

{"amount": {"specifiedAmount": {"currencyCode": "USD", "units": "100"}}, "thresholdRules": [{"thresholdPercent": 0.8}]}

At what spending amount will the alert trigger?

medium

A. $80

B. $8

C. $100

D. $180

Solution

1. Step 1: Identify budget amount

   The budget amount is $100 as specified by "units": "100" in USD.

2. Step 2: Calculate alert trigger amount

   The thresholdPercent is 0.8, meaning 80% of $100, which equals $80.

3. Final Answer:

   $80 -> Option A

4. Quick Check:

   80% of 100 = 80 [OK]

Hint: Multiply budget by thresholdPercent decimal to find alert amount [OK]

Common Mistakes:

• Confusing units with cents
• Using thresholdPercent as 80 instead of 0.8
• Selecting full budget amount instead of threshold

4. You configured a budget alert with this JSON snippet:

{"thresholdRules": [{"thresholdPercent": 1.2}]}

Why does this configuration fail to send alerts?

medium

A. thresholdPercent must be a string, not a number

B. thresholdPercent must be an integer

C. thresholdRules must be empty for alerts to work

D. thresholdPercent cannot be greater than 1 (100%)

Solution

1. Step 1: Check thresholdPercent valid range

   thresholdPercent must be between 0 and 1, representing 0% to 100% of budget.

2. Step 2: Identify invalid value

   1.2 is 120%, which is invalid and causes alert failure.

3. Final Answer:

   thresholdPercent cannot be greater than 1 (100%) -> Option D

4. Quick Check:

   thresholdPercent ≤ 1 required [OK]

Hint: Keep thresholdPercent ≤ 1 to avoid alert failures [OK]

Common Mistakes:

• Using values above 1 for thresholdPercent
• Assuming thresholdPercent must be integer
• Leaving thresholdRules empty disables alerts

5. You want to receive budget alert notifications via email and also trigger an automated workflow using Pub/Sub when spending reaches 90% and 100% of your $200 budget. Which configuration approach is correct?

hard

A. Set two thresholdRules at 0.9 and 1.0, configure email notifications and add a Pub/Sub topic for alerts

B. Set one thresholdRule at 0.95, configure only email notifications, no Pub/Sub needed

C. Set thresholdRules at 90 and 100, configure Pub/Sub only, email alerts are automatic

D. Set thresholdRules at 0.9 and 1.0, but Pub/Sub topics cannot be used for budget alerts

Solution

1. Step 1: Define multiple thresholdRules correctly

   Use decimal values 0.9 and 1.0 for 90% and 100% thresholds.

2. Step 2: Configure both email and Pub/Sub notifications

   Email alerts require notification channels; Pub/Sub topics can be added to automate workflows.

3. Final Answer:

   Set two thresholdRules at 0.9 and 1.0, configure email notifications and add a Pub/Sub topic for alerts -> Option A

4. Quick Check:

   Multiple thresholds + email + Pub/Sub = correct setup [OK]

Hint: Use decimals for thresholds; add email and Pub/Sub for alerts [OK]

Common Mistakes:

• Using whole numbers instead of decimals for thresholds
• Assuming Pub/Sub cannot be used with budget alerts
• Configuring only one threshold for multiple alerts
