D. It allows the function to run continuously without stopping
Correct Answer
B. It executes code only when triggered, reducing unnecessary compute usage
Exam Question 2
In the introduction, what does the instructor emphasize as the project’s core focus?
A. Managing user authentication through AWS Cognito
B. Implementing arithmetic operations using AWS Lambda
C. Building a full-stack web application
D. Migrating legacy systems to cloud infrastructure
Correct Answer
B. Implementing arithmetic operations using AWS Lambda
Exam Question 3
Why is understanding the basics of AWS Lambda important before connecting it to API Gateway?
A. Because Lambda requires complex multi-threading logic
B. Because Lambda cannot be tested without API Gateway
C. Because Lambda must run on a dedicated EC2 instance
D. Because you must understand how the handler processes events
Correct Answer
D. Because you must understand how the handler processes events
Exam Question 4
Why is defining clear API request structures important in this project?
A. Because API Gateway automatically removes undefined parameters
B. Because Lambda supports only XML payloads
C. Because it improves the graphical interface of the AWS console
D. Because Lambda needs consistent input formats to process arithmetic logic correctly
Correct Answer
D. Because Lambda needs consistent input formats to process arithmetic logic correctly
Exam Question 5
When setting up a GET request, what is the main purpose of using query parameters?
A. To define IAM roles required for the Lambda function
B. To control API Gateway usage limits
C. To send numeric input values that Lambda will use for calculations
D. To encrypt the request directly in API Gateway
Correct Answer
C. To send numeric input values that Lambda will use for calculations
Exam Question 6
Why is a POST request used in addition to a GET request in this workflow?
A. Because POST allows sending structured JSON bodies for more complex input
B. Because GET requests cannot send any data
C. Because POST requests automatically validate arithmetic logic
D. Because POST requests cost less than GET requests
Correct Answer
A. Because POST allows sending structured JSON bodies for more complex input
Exam Question 7
What is one reason AWS Lambda is suitable for simple arithmetic operations?
A. It efficiently runs lightweight code only when triggered
B. It requires manually configuring servers for each calculation
C. It stores all computations automatically for future use
D. It guarantees zero latency for all arithmetic functions
Correct Answer
A. It efficiently runs lightweight code only when triggered
Exam Question 8
What does the project introduction emphasize about Lambda’s execution model?
A. The function must be scheduled manually with cron jobs
B. The function requires a web server to stay active
C. The function is invoked on demand in response to events
D. The function keeps running in the background all day
Correct Answer
C. The function is invoked on demand in response to events
Exam Question 9
What is the primary purpose of the Lambda handler function?
A. To generate AWS billing reports
B. To connect Lambda to third-party SDKs automatically
C. To receive event data and execute the defined logic
D. To convert Lambda output into HTML pages
Correct Answer
C. To receive event data and execute the defined logic
Exam Question 10
Why is Python a suitable language for the Lambda function in this project?
A. It requires no indentation rules
B. It allows writing small, clean functions ideal for serverless execution
C. It is the only language supported by AWS Lambda
D. It cannot process numeric values directly
Correct Answer
B. It allows writing small, clean functions ideal for serverless execution
Exam Question 11
Why is understanding API Gateway important before sending requests to Lambda?
A. API Gateway automatically patches Lambda code
B. API Gateway stores API responses persistently
C. API Gateway encrypts Lambda environment variables
D. API Gateway controls how external users send data into Lambda
Correct Answer
D. API Gateway controls how external users send data into Lambda
Exam Question 12
What is one key characteristic of GET requests in this project?
A. They automatically validate all numerical inputs
B. They always modify data on the server
C. They can only be used for JSON payloads
D. They pass simple values via query parameters
Correct Answer
D. They pass simple values via query parameters
Exam Question 13
Why might a POST request be preferred over a GET request in arithmetic operations?
A. POST requests always run faster than GET
B. POST requests prevent Lambda cold starts
C. POST requests allow sending complex, structured data bodies
D. POST requests encrypt data by default
Correct Answer
C. POST requests allow sending complex, structured data bodies
Exam Question 14
What is an important consideration when designing the API request structure?
A. Query parameters cannot be optional
B. Every request must include at least 10 parameters
C. The Lambda function expects inputs in a consistent format
D. The API must include graphical elements for user interaction
Correct Answer
C. The Lambda function expects inputs in a consistent format
Exam Question 15
Why must the developer test both GET and POST integrations separately?
A. AWS requires two tests before publishing any API
B. Each method sends inputs differently and may require different handling
C. API Gateway blocks POST requests unless GET is tested first
D. Lambda can only process one method per deployment
Correct Answer
B. Each method sends inputs differently and may require different handling
