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: You're troubleshooting connectivity issues with an AWS Lambda function that's integrated with a VPC. What are some potential reasons for the connectivity issues, and how would you troubleshoot them?
- Network ACL settings
- Security group rules
- Subnet route table configuration
- VPC peering issues
Connectivity issues with an AWS Lambda function integrated with a VPC could be caused by various factors such as subnet route table configuration, security group rules, network ACL settings, or VPC peering issues. Troubleshooting involves identifying and addressing the specific cause of the connectivity problem.
What is Cross-Account Access in AWS?
- Creating duplicate resources in different accounts
- Granting permissions to resources in one AWS account to users or resources in another AWS account
- Sharing AWS resources within the same account
- Transferring ownership of resources
Cross-Account Access in AWS involves granting permissions to resources, such as S3 buckets or EC2 instances, in one AWS account to users or resources in another AWS account.
How does Cross-Account Access facilitate collaboration between different AWS accounts?
- By allowing resources in one AWS account to be securely accessed by users in another AWS account
- By automatically syncing data between accounts
- By creating separate instances of resources for each account
- By limiting access to resources within the same account
Cross-Account Access facilitates collaboration between different AWS accounts by enabling resources, such as Lambda functions or RDS databases, in one account to be securely accessed by users or resources in another account.
What role does IAM play in Cross-Account Access?
- IAM is only used for authentication within the same AWS account
- IAM is primarily used for billing purposes
- IAM is responsible for resource provisioning
- IAM is used to manage permissions and access policies for users and resources across different AWS accounts
IAM plays a crucial role in Cross-Account Access by allowing administrators to define and manage permissions and access policies for users and resources across different AWS accounts.
Cross-Account Access can be used for various purposes such as centralized ________ management and sharing resources between different departments.
- Authentication
- Configuration
- Identity
- Logging
Cross-Account Access can be used for various purposes such as centralized identity management and sharing resources between different departments.
When implementing Cross-Account Access, it's essential to regularly review and audit ________ to ensure security.
- Billing
- Connectivity
- Data
- Permissions
Regularly reviewing and auditing permissions granted through Cross-Account Access is essential to ensure security and compliance with organizational policies.
AWS provides mechanisms such as ________ to help monitor and control access in Cross-Account scenarios.
- CloudFormation
- IAM Roles
- NAT Gateways
- VPC Peering
AWS provides mechanisms such as IAM Roles to help monitor and control access in Cross-Account scenarios.
