A company wants to use an AWS service to monitor the health of application endpoints, with the ability to route traffic to healthy regional endpoints to improve application availability.

Which service will support these requirements?
- Amazon Inspector
- Amazon CloudWatch
- AWS Global Accelerator
- Amazon CloudFront
Explanation:
AWS Global Accelerator uses the AWS global network to optimize the path from your users to your applications, improving the performance of your traffic by as much as 60%. AWS Global Accelerator continually monitors the health of your application endpoints and redirects traffic to healthy endpoints in less than 30 seconds.
According to the AWS Well-Architected Framework, what change management steps should be taken to achieve reliability in the AWS Cloud? (Choose two.)
- Use AWS Config to generate an inventory of AWS resources
- Use service limits to prevent users from creating or making changes to AWS resources
- Use AWS CloudTrail to record AWS API calls into an auditable log file
- Use AWS Certificate Manager to whitelist approved AWS resources and services
- Use Amazon GuardDuty to validate configuration changes made to AWS resources
Which service can be used to monitor and receive alerts for AWS account root user AWS Management Console sign-in events?
- Amazon CloudWatch
- AWS Config
- AWS Trusted Advisor
- AWS IAM
Which design principle should be considered when architecting in the AWS Cloud?
- Think of servers as non-disposable resources
- Use synchronous integration of services
- Design loosely coupled components
- Implement the least permissive rules for security groups
Which AWS services can be used to move data from on-premises data centers to AWS? (Choose two.)
- AWS Snowball
- AWS Lambda
- Amazon ElastiCache
- AWS Database Migration Service (AWS DMS)
- Amazon API Gateway
A batch workload takes 5 hours to finish on an Amazon EC2 instance. The amount of data to be processed doubles monthly and the processing time is proportional.

What is the best cloud architecture to address this consistently growing demand?
- Run the application on a bigger EC2 instance size.
- Switch to an EC2 instance family that better matches batch requirements.
- Distribute the application across multiple EC2 instances and run the workload in parallel.
- Run the application on a bare metal EC2 instance.
Each department within a company has its own independent AWS account and its own payment method. New company leadership wants to centralize departmental governance and consolidate payments.

How can this be achieved using AWS services or features?
- Forward monthly invoices for each account. Then create IAM roles to allow cross-account access.
- Create a new AWS account. Then configure AWS Organizations and invite all existing accounts to join.
- Configure AWS Organizations in each of the existing accounts. Then link all accounts together.
- Use Cost Explorer to combine costs from all accounts. Then replicate IAM policies across accounts.
The ability to horizontally scale Amazon EC2 instances based on demand is an example of which concept in the AWS Cloud value proposition?
- Economy of scale
- Elasticity
- High availability
- Agility
An ecommerce company anticipates a huge increase in web traffic for two very popular upcoming shopping holidays.

Which AWS service or feature can be configured to dynamically adjust resources to meet this change in demand?
- AWS CloudTrail
- Amazon EC2 Auto Scaling
- Amazon Forecast
- AWS Config
Which AWS service enables users to securely connect to AWS resources over the public internet?
- Amazon VPC peering
- AWS Direct Connect
- AWS VPN
- Amazon Pinpoint
Which tool is used to forecast AWS spending?
- AWS Trusted Advisor
- AWS Organizations
- Cost Explorer
- Amazon Inspector
A company is running an ecommerce application hosted in Europe. To decrease latency for users who access the website from other parts of the world, the company would like to cache frequently accessed static content closer to the users.

Which AWS service will support these requirements?
- Amazon ElastiCache
- Amazon CloudFront
- Amazon Elastic File System (Amazon EFS)
- Amazon Elastic Block Store (Amazon EBS)
Explanation:
Amazon CloudFront employs a global network of edge locations and regional edge caches that cache copies of your content close to your viewers. Amazon CloudFront ensures that end-user requests are served by the closest edge location. As a result, viewer requests travel a short distance, improving performance for your viewers. For files not cached at the edge locations and the regional edge caches, Amazon CloudFront keeps persistent connections with your origin servers so that those files can be fetched from the origin servers as quickly as possible.
Which of the following is a component of the AWS Global Infrastructure?
- Amazon Alexa
- AWS Regions
- Amazon Lightsail
- AWS Organizations
Which AWS service will help users determine if an application running on an Amazon EC2 instance has sufficient CPU capacity?
- Amazon CloudWatch
- AWS Config
- AWS CloudTrail
- Amazon Inspector
