How can you access environment variables within an AWS Lambda function?
- By making API calls
- Hardcoding in the function code
- Using the process environment object
- Via AWS Management Console
Environment variables within an AWS Lambda function can be accessed using the process environment object, which provides access to variables set at runtime.
What is the maximum number of environment variables that can be set for an AWS Lambda function?
- 1024
- 256
- 512
- Unlimited
AWS Lambda allows a maximum of 1024 environment variables to be set for a function, providing ample flexibility for configuration and customization.
How can you update environment variables for a deployed AWS Lambda function?
- Programmatically using SDKs
- Through direct SSH access
- Using the AWS Management Console
- Via AWS CLI
Environment variables for a deployed AWS Lambda function can be updated using the AWS Management Console by navigating to the function's configuration and modifying the environment variables section.
What are some best practices for managing environment variables in AWS Lambda?
- Hardcode values directly into the function code
- Share environment variables among Lambda functions through global variables
- Store environment variables in plaintext files on the Lambda instance
- Use AWS Secrets Manager or AWS Systems Manager Parameter Store
Best practices for managing environment variables in AWS Lambda include using AWS Secrets Manager or AWS Systems Manager Parameter Store to store sensitive data securely.
Can environment variables be dynamically changed during the execution of an AWS Lambda function?
- It depends on the programming language used
- No
- Only if the function is invoked asynchronously
- Yes
No, environment variables in AWS Lambda cannot be dynamically changed during execution; they are set when the function is deployed and remain constant throughout its execution.
Environment variables in AWS Lambda are commonly used to store configuration settings such as __________.
- API keys
- Encryption keys
- Lambda function code
- Source code
Environment variables in AWS Lambda are often used to store sensitive information like API keys, database credentials, or other configuration settings.
The process of setting environment variables for an AWS Lambda function is typically done during __________.
- Function configuration
- Function deployment
- Function execution
- Function invocation
Setting environment variables for an AWS Lambda function is part of its configuration process, allowing you to customize its behavior.
Scenario: During the execution of an AWS Lambda function, you need to dynamically adjust certain parameters based on incoming data. How would you approach this using environment variables?
- Store adjustable parameters in a plaintext configuration file
- Use AWS CloudWatch Events to trigger parameter updates
- Use AWS Step Functions to dynamically adjust parameters
- Use environment variables to store adjustable parameters
Leveraging environment variables to store adjustable parameters allows you to dynamically adjust certain parameters during the execution of a Lambda function based on incoming data, providing flexibility and scalability.
AWS Lambda provides a secure way to store and access sensitive information through the use of __________.
- AWS DynamoDB
- AWS IAM
- AWS S3
- AWS Secrets Manager
AWS Lambda can securely access sensitive information stored in AWS Secrets Manager, such as database credentials or API keys.
In AWS Lambda, environment variables can be updated using the ________ service.
- AWS CLI
- AWS CloudFormation
- AWS Management Console
- AWS SDK
Environment variables in AWS Lambda can be updated using the AWS Management Console, providing a user-friendly interface for configuration.
