A car rental company has built a serverless REST API to provide data to its mobile app. The app consists of an Amazon API Gateway API with a Regional endpoint, AWS Lambda functions, and an Amazon Aurora MySQL Serverless DB cluster. The company recently opened the API to mobile apps of partners. A significant increase in the number of requests resulted, causing sporadic database memory errors. Analysis of the API traffic indicates that clients are making multiple HTTP GET requests for the same queries in a short period of time. Traffic is concentrated during business hours, with spikes around holidays and other events.
The company needs to improve its ability to support the additional usage while minimizing the increase in costs associated with the solution.
Which strategy meets these requirements?
A. Convert the API Gateway Regional endpoint to an edge-optimized endpoint. Enable caching in the production stage.A solutions architect is implementing infrastructure as code for a two-tier web application in an AWS CloudFormation template. The web frontend application will be deployed on Amazon EC2 instances in an Auto Scaling group. The backend database will be an Amazon RDS for MySQL DB instance. The database password will be rotated every 60 days.
How can the solutions architect MOST securely manage the configuration of the application's database credentials?
A. Provide the database password as a parameter in the CloudFormation template. Create an initialization script in the Auto Scaling group's launch configuration UserData property to reference the password parameter using the Ref intrinsic function. Store the password on the EC2 instances. Reference the parameter for the value of the MasterUserPassword property in the AWS::RDS::DBInstance resource using the Ref intrinsic function.An organization is having an application which can start and stop an EC2 instance as per schedule. The organization needs the MAC address of the instance to be registered with its software. The instance is launched in EC2-CLASSIC. How can the organization update the MAC registration every time an instance is booted?
A. The organization should write a boot strapping script which will get the MAC address from the instance metadata and use that script to register with the application.AWS ________supports__________ environments as one of the AWS resource types.
A. Elastic Beanstalk; Elastic Beanstalk applicationA company has an application that runs a web service on Amazon EC2 instances and stores .jpg images in Amazon S3. The web traffic has a predictable baseline, but often demand spikes unpredictably for short periods of time. The application is loosely coupled and stateless. The .jpg images stored in Amazon S3 are accessed frequently for the first 15 to 20 days, they are seldom accessed thereafter but always need to be immediately available. The CIO has asked to find ways to reduce costs.
Which of the following options will reduce costs? (Choose two.)
A. Purchase Reserved instances for baseline capacity requirements and use On-Demand instances for the demand spikes.A user has created a VPC with public and private subnets. The VPC has CIDR 20.0.0.0/16. The private subnet uses CIDR 20.0.1.0/24 and the public subnet uses CIDR 20.0.0.0/24. The user is planning to host a web server in the public subnet (port 80) and a DB server in the private subnet (port 3306). The user is configuring a security group of the NAT instance.
Which of the below mentioned entries is not required in NAT's security group for the database servers to connect to the Internet for software updates?
A. For Outbound allow Destination: 0.0.0.0/0 on port 443A company is deploying a new cluster for big data analytics on AWS. The cluster will run across many Linux Amazon EC2 instances that are spread across multiple Availability Zones.
All of the nodes in the cluster must have read and write access to common underlying file storage. The file storage must be highly available, must be resilient, must be compatible with the Portable Operating System Interface (POSIX), and
must accommodate high levels of throughput.
Which storage solution will meet these requirements?
A. Provision an AWS Storage Gateway file gateway NFS file share that is attached to an Amazon S3 bucket. Mount the NFS file share on each EC2 instance In the cluster.Your company runs a customer facing event registration site This site is built with a 3-tier architecture with web and application tier servers and a MySQL database The application requires 6 web tier servers and 6 application tier servers for normal operation, but can run on a minimum of 65% server capacity and a single MySQL database.
When deploying this application in a region with three availability zones (AZs) which architecture provides high availability?
A. A web tier deployed across 2 AZs with 3 EC2 (Elastic Compute Cloud) instances in each AZ inside an Auto Scaling Group behind an ELB (elastic load balancer), and an application tier deployed across 2 AZs with 3 EC2 instances in each AZ inside an Auto Scaling Group behind an ELB and one RDS (Relational Database Service) instance deployed with read replicas in the other AZ.A company asks a solution architect to optimize the cost of a solution. The solution handles requests from multiple customers. The solution includes a multi-tier architecture that uses Amazon API Gateway, AWS Lambda, AWS Fargate, Amazon Simple Queue Service (Amazon SQS), and Amazon EC2.
In the current setup, requests go through API Gateway to Lambda and either start a container in Fargate or push a message to an SQS queue. An EC2 Fleet provides EC2 instances that serve as workers for the SQS queue. The EC2 Fleet scales based on the number of items in the SQS queue.
Which combination of steps should the solutions architect recommend to reduce cost the MOST? (Choose three.)
A. Determine the minimum number of EC2 instances that are needed during a day. Reserve this number of instances in a 3-year plan with payment all upfront.What does elasticity mean to AWS?
A. The ability to scale computing resources up easily, with minimal friction and down with latency.Nowadays, the certification exams become more and more important and required by more and more enterprises when applying for a job.
