A three-tier application is being created to host small news articles. The application is expected to serve millions of users. When breaking news occurs, the site must handle very large spikes in traffic without significantly impacting database performance.
Which design meets these requirements while minimizing costs?
A. Use Auto Scaling groups to increase the number of Amazon EC2 instances delivering the web applicationA company wants to improve latency by hosting images within a public Amazon S3 bucket fronted by an Amazon CloudFront distribution. The company wants to restrict access to the S3 bucket to include the CloudFront distribution only, while also allowing CloudFront to continue proper functionality.
What should be done after making the bucket private to restrict access with the LEAST operational overhead?
A. Create a CloudFront origin access identity and create a security group that allows access from CloudFront.An application running in a private subnet accesses an Amazon DynamoDB table. There is a security requirement that the data never leave the AWS network. How should this requirement be met?
A. Configure a network ACL on DynamoDB to limit traffic to the private subnetA Solutions Architect is designing a microservice to process records from Amazon Kinesis Streams. The metadata must be stored in Amazon DynamoDB. The microservice must be capable of concurrently processing 10,000 records daily as they arrive in the Kinesis stream.
The MOST scalable way to design the microservice is:
A. As an AWS Lambda function.A corporate web application is deployed within an Amazon Virtual Private Cloud (VPC) and is connected to the corporate data center via an iPsec VPN. The application must authenticate against the on-premises LDAP server. After authentication, each logged-in user can only access an Amazon Simple Storage Space (S3) keyspace specific to that user.
Which two approaches can satisfy these objectives? (Choose two.)
A. Develop an identity broker that authenticates against IAM security Token service to assume a IAM role in order to get temporary AWS security credentials The application calls the identity broker to get AWS temporary security credentials with access to the appropriate S3 bucket.A company is designing a new application to collect data on user behavior for analysis at a later time. Amazon Kinesis Data Streams will be used to receive user interaction events. What should be done to ensure the event data is retained indefinitely?
A. Configure the stream to write records to an attached Amazon EBS volume.An on-premises database is experiencing significant performance problems when running SQL queries. With 10 users, the lookups are performing as expected. As the number of users increases, the lookups take three times longer than expected to return values to an application.
Which action should a Solutions Architect take to maintain performance as the user count increases?
A. Use Amazon SQS.A Solutions Architect is designing a public-facing web application for employees to upload images to their social media account. The application consists of multiple Amazon EC2 instances behind an elastic load balancer, an Amazon S3 bucket where uploaded images are stored, and an Amazon DynamoDB table for storing image metadata.
Which AWS service can the Architect use to automate the process of updating metadata in the DynamoDB table upon image upload?
A. Amazon CloudWatchA Solutions Architect is designing a multicontainer-based web application. Parts of the web application, /orders and /sale-event, must scale independently while maintaining a single Fully Qualified Domain Name. Which AWS services will help the Architect build this platform? (Select TWO.)
A. Amazon ELB Application Load BalancerA web application experiences high compute costs due to serving a high amount of static web content. How should the web server architecture be designed to be the MOST cost-efficient?
A. Create an Auto Scaling group to scale out based on average CPU usage.Nowadays, the certification exams become more and more important and required by more and more enterprises when applying for a job.
