Amazon AWS Certified Solution Architect Associate- SAA Set 1

1.

A solutions architect is designing the cloud architecture for a new application being deployed on AWS. The process should run in parallel while adding and removing application nodes as needed based on the number of jobs to be processed. The processor application is stateless. The solutions architect must ensure that the application is loosely coupled and the job items are durably stored.
Which design should the solutions architect use?

Create an Amazon SNS topic to send the jobs that need to be processed. Create an Amazon Machine Image (AMI) that consists of the processor application. Create a launch configuration that uses the AMI. Create an Auto Scaling
groupusing the launch configuration. Set the scaling policy for the Auto Scaling group to add and remove nodes based on CPU usage. Create an Amazon SQS queue to hold the jobs that need to be processed. Create an Amazon Machine Image (AMI) that consists of the processor application. Create a launch configuration that uses the AMI. Create an Auto Scalinggroupusing the launch configuration. Set the scaling policy for the Auto Scaling group to add and remove nodes based on network usage. Create an Amazon SQS queue to hold the jobs that need to be processed. Create an Amazon Machine Image (AMI) that consists of the processor application. Create a launch template that uses the AMI. Create an Auto Scalinggroupusing the launch template. Set the scaling policy for the Auto Scaling group to add and remove nodes based on the number of items in the SQS queue. Create an Amazon SNS topic to send the jobs that need to be processed. Create an Amazon Machine Image (AMI) that consists of the processor application. Create a launch template that uses the AMI. Create an Auto Scaling groupusingthe launch template. Set the scaling policy for the Auto Scaling group to add and remove nodes based on the number of messages published to the SNS topic.

A company hosts its product information webpages on AWS. The existing solution uses multiple Amazon C2 instances behind an Application Load Balancer in an Auto Scaling group. The website also uses a custom DNS name and communicates with HTTPS only using a dedicated SSL certificate. The company is planning a new product launch and wants to be sure that users from around the world have the best possible experience on the new website.
What should a solutions architect do to meet these requirements?

Redesign the application to use Amazon CloudFront. Redesign the application to use AWS Elastic Beanstalk. Redesign the application to use a Network Load Balancer. Redesign the application to use Amazon S3 static website hosting.

3.

A media streaming company collects real-time data and stores it in a disk-optimized database system. The company is not getting the expected throughput and wants an in-memory database storage solution that performs faster and provides high availability using data replication.
Which database should a solutions architect recommend?

Amazon RDS for MySQL B.
Amazon RDS for PostgreSQL. Amazon ElastiCache for Redis Amazon ElastiCache for Memcached

4.

A company runs an application on a group of Amazon Linux EC2 instances. The application writes log files using standard API calls. For compliance reasons, all log files must be retained indefinitely and will be analyzed by a reporting tool that must access all files concurrently.
Which storage service should a solutions architect use to provide the MOST cost-effective solution?

Amazon EBS Amazon EFS Amazon EC2 instance store Amazon S3

5.

A company has a multi-tier application that runs six front-end web servers in an Amazon EC2 Auto Scaling group in a single Availability Zone behind an Application Load Balancer (ALB). A solutions architect needs to modify the infrastructure to be highly available without modifying the application.
Which architecture should the solutions architect choose that provides high availability?

Create an Auto Scaling group that uses three instances across each of two Regions. Modify the Auto Scaling group to use three instances across each of two Availability Zones. Create an Auto Scaling template that can be used to quickly create more instances in another Region. Change the ALB in front of the Amazon EC2 instances in a round-robin configuration to balance traffic to the web tier.
