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.
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.
When managing environment variables in AWS Lambda, it's essential to implement ________ to ensure security.
- Encryption
- Load balancing
- Role-based access control
- Version control
Implementing encryption mechanisms helps ensure that sensitive environment variable data remains secure during storage and transmission.
Dynamic configuration changes during execution of AWS Lambda functions can be achieved through the use of ________.
- AWS CloudWatch
- AWS IAM
- AWS Lambda Layers
- Parameter Store
AWS Systems Manager Parameter Store allows you to centrally manage configuration data and secrets, which can be dynamically accessed by AWS Lambda functions during execution.
Scenario: You need to deploy an AWS Lambda function that requires access to an external API key. How would you securely store this API key?
- Hardcode the API key in the Lambda function code
- Pass the API key as an environment variable
- Store the API key in a plaintext configuration file
- Use AWS Secrets Manager
Using AWS Secrets Manager to securely store and manage the API key ensures that it is protected and can be accessed by the Lambda function when needed.
