Monitoring health of application instances
Health checks are important, but merely monitoring does not enhance availability; it needs to be combined with traffic distribution to be effective.
Q141. What is the purpose of AWS Lambda Layers?
Correct answer:
-
AWS Lambda Layers allow you to manage and share code and dependencies across multiple Lambda functions.
They enable you to package shared libraries or runtime dependencies, reducing the size of your deployment package and promoting code reuse.
Other options — why they're wrong:
-
AWS Lambda Layers are used for storing data in S3 buckets.
This is incorrect as S3 buckets are for object storage and not specific to Lambda Layers.|
-
AWS Lambda Layers help in monitoring the performance of Lambda functions.
This is incorrect because monitoring performance is done through AWS CloudWatch, not Layers.|
-
AWS Lambda Layers are designed for managing API Gateway endpoints.
This is incorrect as API Gateway endpoints are managed separately from Lambda Layers.
Q142. Which AWS service provides a way to run containerized applications without managing servers?
Correct answer:
-
AWS Fargate
AWS Fargate allows users to run containers without having to manage the underlying infrastructure, enabling a serverless approach to container management.
Other options — why they're wrong:
-
Amazon EC2
Amazon EC2 requires users to manage virtual servers, which contradicts the idea of running containerized applications without server management.
-
Amazon S3
Amazon S3 is an object storage service, not a service for running containerized applications.
-
AWS Lambda
While AWS Lambda runs code without managing servers, it is not specifically designed for containerized applications like AWS Fargate is.
Q143. How does Amazon S3 event notifications work?
Correct answer:
-
Amazon S3 event notifications allow users to receive notifications when certain events happen in their S3 bucket, such as object creation, deletion, or restoration.
These notifications can be sent to various destinations like AWS Lambda, SNS, or SQS, enabling automated workflows.
Other options — why they're wrong:
-
Amazon S3 event notifications only work with AWS Lambda functions.
This statement is incorrect because S3 event notifications can also be sent to other services like SNS and SQS, not just AWS Lambda.
-
Event notifications are sent immediately after an object is uploaded to S3.
This statement is misleading as event notifications can be triggered by various actions, not just uploads, and the timing may vary based on event processing.
-
S3 event notifications require setting up a CloudWatch alarm to function.
This is incorrect; S3 event notifications do not require CloudWatch alarms, they operate independently from CloudWatch.
Q144. What is the function of AWS Service Control Policies (SCPs)?
Correct answer:
-
Manage permissions for AWS Organizations
SCPs allow you to manage permissions across accounts in an AWS Organization, enabling centralized control over the actions that can be performed.
Other options — why they're wrong:
-
Restrict access to S3 buckets
SCPs do not specifically restrict access to S3 buckets; they govern permissions across AWS services in an organization.
-
Enable multi-factor authentication
SCPs do not enable multi-factor authentication; they are used for managing permissions within AWS Organizations.
-
Monitor AWS account activity
SCPs do not monitor account activity; they are focused on permissions management rather than tracking actions.
Q145. What are the main components of Amazon API Gateway?
Correct answer:
-
API Gateway, VPC Link, and AWS Lambda
These are key components of Amazon API Gateway, enabling API creation, integration, and management.
Other options — why they're wrong:
-
API Gateway, CloudFront, and EC2
CloudFront and EC2 are not main components of API Gateway; they serve different purposes in AWS architecture.
-
API Gateway, S3, and DynamoDB
S3 and DynamoDB are storage solutions and not direct components of API Gateway.
-
API Gateway, IAM, and RDS
While IAM is related to security for API Gateway, RDS is a database service, not a main component of API Gateway.
Q146. How does AWS Shield Advanced enhance protection against DDoS attacks?
Correct answer:
-
AWS Shield Advanced provides real-time attack visibility and DDoS cost protection.
It enhances protection by offering detailed attack diagnostics and financial protections against DDoS attack costs.
Other options — why they're wrong:
-
AWS Shield Advanced is a physical firewall that blocks all DDoS traffic.
This statement is incorrect as AWS Shield Advanced does not function as a physical firewall and cannot block all traffic.|
-
AWS Shield Advanced requires a minimum usage commitment for DDoS protection.
This is incorrect; AWS Shield Advanced operates on a pay-as-you-go model without a minimum usage commitment.|
-
AWS Shield Advanced only protects against application layer attacks.
This statement is incorrect; AWS Shield Advanced protects against both network and application layer attacks.
Q147. What is the purpose of AWS CloudTrail event history?
Correct answer:
-
Provides a record of AWS API calls for auditing
AWS CloudTrail event history allows users to track and record API calls made in their AWS account, which is essential for auditing and compliance purposes.
Other options — why they're wrong:
-
Tracks changes in AWS service limits
This is not the primary purpose of CloudTrail; it primarily focuses on logging API calls.|
-
Monitors real-time performance of AWS services
CloudTrail does not monitor performance; it records API activity instead.|
-
Automates resource provisioning in AWS
CloudTrail is not responsible for resource provisioning; it is focused on logging and auditing API calls.
Q148. How does Amazon RDS support read scaling?
Correct answer:
-
Read Replicas
Amazon RDS supports read scaling by allowing the creation of read replicas, which can offload read traffic from the primary database instance.
Other options — why they're wrong:
-
Multi-AZ Deployments
Multi-AZ deployments provide high availability and failover support but do not specifically enhance read scaling.
-
Vertical Scaling
Vertical scaling involves upgrading to a larger instance type, which does not inherently improve read scaling.
-
Database Sharding
Database sharding involves partitioning data across multiple databases, which is a more complex solution and not directly a feature of Amazon RDS for read scaling.
Q149. What is the significance of AWS Trusted Advisor recommendations?
Correct answer:
-
Improving cost efficiency and performance
AWS Trusted Advisor provides recommendations that help users optimize their AWS resources for cost efficiency, performance, security, and service limits.
Other options — why they're wrong:
-
Enhancing user interface design
AWS Trusted Advisor is not focused on user interface design; it serves to optimize AWS resource utilization.
-
Increasing data storage capacity
AWS Trusted Advisor does not directly relate to increasing data storage capacity; it focuses on optimizing existing resources.
-
Providing training resources for AWS users
AWS Trusted Advisor does not provide training resources; it offers specific recommendations for resource optimization.
Q150. Which AWS service is used to manage and deploy serverless applications with AWS SAM?
Correct answer:
-
AWS Lambda
AWS Lambda is the service that runs your serverless applications, and it integrates with AWS SAM for deployment and management.
Other options — why they're wrong:
-
AWS CloudFormation
CloudFormation is used for infrastructure as code, but not specifically for serverless applications with AWS SAM.
-
Amazon EC2
EC2 is a service for running virtual servers, not for serverless applications.
-
AWS Elastic Beanstalk
Elastic Beanstalk is for deploying web applications, not specifically for serverless applications with AWS SAM.
