How can you delegate permissions in AWS IAM?
- By configuring networking rules
- By creating IAM roles and assigning them to trusted entities
- By granting direct access to AWS services
- By sharing IAM user credentials
Delegating permissions in AWS IAM involves creating IAM roles with the necessary permissions and then assigning those roles to trusted entities such as AWS services, applications, or other AWS accounts.
What is the difference between IAM policies and resource-based policies?
- IAM policies are attached to identities, while resource-based policies are attached to resources
- IAM policies are managed by AWS, while resource-based policies are managed by users
- IAM policies are only applicable to S3 buckets, while resource-based policies apply to other AWS services
- IAM policies control network traffic, while resource-based policies control resource configurations
IAM policies control access to AWS services and resources, specifying what actions are allowed or denied for IAM users, groups, or roles. Resource-based policies, on the other hand, are attached directly to resources like S3 buckets or Lambda functions, controlling access from other accounts or services.
How does IAM manage access to AWS services?
- Through direct access to services
- Through direct network configuration
- Through direct resource ownership
- Through policies attached to IAM entities
IAM manages access to AWS services through policies that are attached to IAM users, groups, or roles, defining what actions they can perform on which AWS resources.
What is the purpose of IAM policies attached to IAM users or groups?
- To define permissions for accessing AWS resources
- To define user authentication methods
- To manage billing information
- To manage network configurations
IAM policies attached to IAM users or groups are used to define the permissions that users or groups have for accessing AWS resources, specifying allowed actions and resources.
What is the least privilege principle in IAM?
- Giving users all available permissions
- Giving users only the permissions they need
- Giving users permissions based on their job titles
- Giving users temporary permissions
The least privilege principle in IAM involves granting users or roles only the permissions they need to perform their tasks, reducing the risk of excessive access.
How do you grant permissions to an IAM role?
- By attaching IAM policies
- By configuring network settings
- By creating new IAM users
- By installing third-party software
Permissions in IAM roles are granted by attaching IAM policies, which define the actions that can be performed and the resources that can be accessed.
How are IAM roles different from IAM users?
- IAM roles are meant for temporary access
- IAM roles are only used for authentication
- IAM roles are specific to AWS services
- IAM roles cannot have policies attached
IAM roles in AWS are intended for temporary access by entities such as EC2 instances or AWS services, while IAM users are typically for long-term access by humans or applications.
What are the fundamental components of an IAM policy?
- Functions, Variables, Conditions
- Regions, Availability Zones, Endpoints
- Statements, Effects, Resources
- Users, Groups, Roles
IAM policies consist of statements that define the permissions, effects that determine whether the permissions are allowed or denied, and resources to which the policy applies.
What is the primary purpose of IAM roles in AWS?
- Authenticating users
- Delegating permissions
- Managing billing
- Storing data
IAM roles in AWS are used to delegate permissions to entities such as AWS services, EC2 instances, or applications, without the need for long-term credentials.
Version __________ is crucial when specifying dependencies to ensure compatibility and stability in AWS Lambda environments.
- bundling
- freezing
- locking
- pinning
Version pinning involves specifying exact versions of dependencies to ensure consistent behavior in AWS Lambda environments.
Dependency management tools such as __________ can be used to automate the installation of required libraries for AWS Lambda functions.
- Composer
- Maven
- npm
- pip
Pip is a package installer for Python, commonly used for managing dependencies in AWS Lambda functions developed using Python.
How does AWS Lambda deployment packaging affect dependency management?
- It has no effect on performance
- It impacts cold start times
- It improves scalability
- It simplifies security
AWS Lambda deployment packaging directly affects dependency management by influencing cold start times; larger packages can lead to longer cold start times due to increased initialization overhead.
