How are dependencies typically managed in an AWS Lambda function?
- Manually copying files into the Lambda environment
- Relying on AWS to automatically install dependencies
- Uploading dependencies as part of the Lambda function code
- Using package managers like npm or pip
Dependencies in an AWS Lambda function are typically managed using package managers such as npm for Node.js or pip for Python.
What are dependencies in the context of AWS Lambda?
- AWS services used by a Lambda function
- Environment variables in a Lambda function
- External libraries or modules required by a Lambda function
- Internal functions within a Lambda function
Dependencies in the context of AWS Lambda refer to external libraries or modules that a Lambda function relies on to perform its tasks.
Scenario: You are managing a large AWS environment with multiple teams. How would you implement IAM best practices to ensure secure access management across the organization?
- Grant all permissions to all IAM users
- Implement IAM roles with appropriate permissions for each team's specific responsibilities and enforce the use of IAM groups to manage user access efficiently.
- Share IAM user credentials across teams
- Use a single IAM role for all teams
Implementing IAM roles with appropriate permissions for each team's specific responsibilities and enforcing the use of IAM groups to manage user access efficiently is a best practice for ensuring secure access management across the organization.
Scenario: Your organization follows the principle of least privilege. How would you design IAM policies to adhere to this principle effectively?
- Grant IAM users and roles only the permissions they need to perform their tasks, using the principle of least privilege.
- Grant administrative access to all IAM users and roles
- Grant all permissions to all IAM users and roles
- Share IAM access keys with all users
Designing IAM policies to grant IAM users and roles only the permissions they need to perform their tasks adheres to the principle of least privilege effectively.
IAM users can be members of multiple __________ to manage access more efficiently.
- Accounts
- Groups
- Policies
- Roles
IAM users can be members of multiple groups to manage access more efficiently, allowing for easier management of permissions across multiple users.
__________ defines the maximum permissions an IAM policy can grant.
- Permissions boundary
- Policy document
- Resource policy
- Role
The permissions boundary defines the maximum permissions an IAM policy can grant, helping to control and limit the scope of permissions assigned to entities.
__________ testing verifies the integration between different components of a serverless application, including AWS Lambda functions.
- End-to-end
- Integration
- Performance
- Unit
Integration testing verifies the integration between different components of a serverless application, including AWS Lambda functions, to ensure they work together as expected.
During testing, you can use AWS Lambda __________ to simulate events such as S3 uploads or API Gateway requests.
- Content Delivery Networks (CDNs)
- Identity and Access Management (IAM) roles
- Load balancers
- Local testing framework
A local testing framework allows you to simulate events locally, such as S3 uploads or API Gateway requests, for testing AWS Lambda functions before deployment.
Which AWS service can help you monitor the performance of Lambda functions during testing?
- AWS CloudWatch
- AWS EC2
- AWS RDS
- AWS S3
AWS CloudWatch provides monitoring and observability services, including metrics, logs, and alarms, allowing you to monitor the performance of Lambda functions during testing and in production environments.
How can you automate testing and deployment of AWS Lambda functions?
- Email notifications
- Manual deployment
- Using CI/CD pipelines
- Using physical servers
Implementing continuous integration and continuous deployment (CI/CD) pipelines allows you to automate testing and deployment processes for AWS Lambda functions, ensuring faster and more reliable releases.
What are some best practices for integration testing of AWS Lambda functions?
- Limiting testing to unit tests
- Manually testing each function
- Skipping testing altogether
- Using a staging environment
Using a staging environment similar to production can help mimic real-world scenarios and validate the integration of AWS Lambda functions with other services.
What is the purpose of unit testing in AWS Lambda function development?
- To deploy infrastructure as code
- To monitor production performance
- To test individual units or components of code
- To test the entire application end-to-end
Unit testing in AWS Lambda function development allows developers to test individual units or components of code in isolation, ensuring they work as expected before integration and deployment.
