When configuring VPC integration for AWS Lambda, you must specify one or more __________ for the function.
- Route tables
- Security groups
- Subnets
- VPC endpoints
When configuring VPC integration for AWS Lambda, you must specify one or more subnets for the function to use within the Virtual Private Cloud (VPC).
AWS Lambda functions with VPC integration may experience increased __________ due to networking overhead.
- CPU utilization
- Latency
- Memory usage
- Throughput
AWS Lambda functions with VPC integration may experience increased latency due to networking overhead introduced by routing traffic through the Virtual Private Cloud (VPC).
To reduce cold start times when using VPC integration, consider using __________.
- API Gateway
- IAM Roles
- Provisioned Concurrency
- Route 53
Provisioned Concurrency is a feature in AWS Lambda that helps reduce cold start times by pre-initializing execution environments, especially useful when integrating with a VPC.
__________ allows you to securely access resources within a VPC from your AWS Lambda functions.
- NAT Gateways
- Security Groups
- VPC Endpoints
- Virtual Private Gateways
VPC Endpoints allow you to securely access resources within a VPC from your AWS Lambda functions.
When configuring VPC integration for AWS Lambda, you can optionally specify __________ to control outbound internet access.
- Security Groups
- Subnet Route Tables
- VPC Endpoint Policies
- VPC Peering Connections
Security Groups can be specified when configuring VPC integration for AWS Lambda to control outbound internet access from the functions.
Scenario: You have an AWS Lambda function that needs to access resources within a VPC, but you're concerned about performance. What steps would you take to optimize the function's performance?
- Decrease timeout settings
- Enable AWS X-Ray tracing
- Increase memory allocation
- Utilize provisioned concurrency
Utilizing provisioned concurrency in AWS Lambda allows you to preallocate concurrency to your function, reducing cold starts and improving performance when accessing resources within a VPC.
Scenario: Your team is planning to use AWS Lambda functions with VPC integration for processing sensitive data. What security measures would you implement to ensure data privacy and compliance?
- Enable AWS Key Management Service (KMS) encryption
- Enable VPC flow logs
- Implement VPC endpoint policies
- Use IAM roles with least privilege
Implementing VPC endpoint policies allows you to control access to services within your VPC, ensuring that only authorized entities can interact with Lambda functions processing sensitive data.
Scenario: Your organization has multiple AWS accounts for different departments. How would you set up Cross-Account Access to allow a central security team to audit resources across all accounts?
- Create IAM roles with appropriate permissions in each account and establish trust relationships with the central security account.
- Enable AWS Organizations and configure cross-account access policies for the central security team.
- Share root account credentials with the central security team for direct access to all accounts.
- Use IAM users with cross-account access policies for each department to grant access to the central security team.
By creating IAM roles with the necessary permissions in each AWS account and establishing trust relationships with the central security account, you can enable the central security team to audit resources across all accounts securely.
What are the primary methods for granting Cross-Account Access in AWS?
- Access keys
- Bucket policies
- EC2 instance profiles
- IAM Roles and IAM users
IAM Roles and IAM users are the primary methods for granting Cross-Account Access in AWS.
How do you set up Cross-Account Access using IAM roles?
- Create IAM users
- Enable MFA
- Establish trust relationships between accounts
- Share access keys
To set up Cross-Account Access using IAM roles, you establish trust relationships between the accounts involved, allowing one account to assume roles in the other account.
