Amazon SAA-C01 Online Questions & Answers

• Question 391:

  A Solutions Architect is designing a ride-sharing application. The application needs consistent and single-digit millisecond latency. In addition, the application must integrate with a highly scalable and fully managed database service to track GPS coordinates and user data for all rides.

  Which database service should the Solutions Architect use to meet these performance requirements?

  A. Amazon RDS
  B. Amazon Redshift
  C. Amazon DynamoDB
  D. Amazon Aurora
  C. Amazon DynamoDB

• Question 392:

  An application runs on multiple Amazon EC2 instances. Each running instance of the application must have access to a shared file system. Where should the data be stored?

  A. Amazon S3
  B. Amazon DynamoDB
  C. Amazon EFS
  D. Amazon EBS
  C. Amazon EFS

• Question 393:

  An application running on AWS Lambda requires an API key to access a third-party service. The key must be stored securely with audited access to the Lambda function only. What is the MOST secure way to store the key?

  A. As an object in Amazon S3
  B. As a secure string in AWS Systems Manager Parameter Store
  C. Inside a file on an Amazon EBS volume attached to the Lambda function
  D. Inside a secrets file stored on Amazon EFS
  B. As a secure string in AWS Systems Manager Parameter Store

• Question 394:

  A Solutions Architect is considering possible options for improving the security of the data on an Amazon EBS volume attached to an Amazon EC2 instance. Which solution will improve the security of the data?

  A. Use AWS KMS to encrypt the EBS volume
  B. Create an IAM policy that restricts read and write access to the volume
  C. Migrate the sensitive data to an instance store volume
  D. Use Amazon single sign-on to control login access to the EC2 instance
  A. Use AWS KMS to encrypt the EBS volume

• Question 395:

  A large media site has multiple applications in Amazon ECS. A Solutions Architect needs to use content metadata and route traffic to specific services. What is the MOST efficient method to perform this task?

  A. Use an AWS Classic Load Balancer with a host-based routing option to route traffic to the correct service.
  B. Use the AWS CLI to update Amazon Route 53 hosted zone to route traffic as services get updated.
  C. Use an AWS Application Load Balancer with host-based routing option to route traffic to the correct service.
  D. Use Amazon CloudFront to manage and route traffic to the correct service.
  A. Use an AWS Classic Load Balancer with a host-based routing option to route traffic to the correct service.

• Question 396:

  Your application is using an ELB in front of an Auto Scaling group of web/application servers deployed across two AZs and a Multi-AZ RDS Instance for data persistence. The database CPU is often above 80% usage and 90% of I/O operations on the database are reads. To improve performance you recently added a single-node Memcached ElastiCache Cluster to cache frequent DB query results. In the next weeks the overall workload is expected to grow by 30%. Do you need to change anything in the architecture to maintain the high availability or the application with the anticipated additional load? Why?

  A. Yes, you should deploy two Memcached ElastiCache Clusters in different AZs because the RDS instance will not be able to handle the load if the cache node fails.
  B. No, if the cache node fails you can always get the same data from the DB withouthaving any availability impact.
  C. No, if the cache node fails the automated ElastiCache node recovery feature will prevent any availability impact.
  D. Yes, you should deploy the Memcached ElastiCache Cluster with two nodes in the same AZ as the RDS DB master instance to handle the load if one cache node fails.
  A. Yes, you should deploy two Memcached ElastiCache Clusters in different AZs because the RDS instance will not be able to handle the load if the cache node fails.

• Question 397:

  An organization has a long-running image processing application that runs on Spot Instances that will be terminated when interrupted. A highly available workload must be designed to respond to Spot Instance interruption notices. The solution must include a two-minute warning when there is not enough capacity.

  How can these requirements be met?

  A. Use Amazon CloudWatch Events to invoke an AWS Lambda function that can launch On-Demand Instances.
  B. Regularly store data from the application on Amazon DynamoDB. Increase the maximum number of instances in the AWS Auto Scaling group.
  C. Manually place a bid for additional Spot Instances at a higher price in the same AWS Region and Availability Zone.
  D. Ensure that the Amazon Machine Image associated with the application has the latest configurations for the launch configuration.
  B. Regularly store data from the application on Amazon DynamoDB. Increase the maximum number of instances in the AWS Auto Scaling group.

• Question 398:

  A Solutions Architect has a three-tier web application that serves customers worldwide. Analysis reveals that product images take more time to load than expected. Which action will improve the image load time?

  A. Store product images on Amazon EBS-optimized storage volumes
  B. Store product images in an Amazon S3 bucket
  C. Use an Amazon CloudFront distribution for product images
  D. Use an Auto Scaling group to add instances for product images
  C. Use an Amazon CloudFront distribution for product images

• Question 399:

  A Solutions Architect has five web servers serving requests for a domain.

  Which of the following Amazon Route 53 routing policies can distribute traffic randomly among all healthy web servers?

  A. Simple
  B. Failover
  C. Weighted
  D. Multivalue Answer
  D. Multivalue Answer

• Question 400:

  A Solution Architect is designing an application that uses Amazon EBS volumes. The volumes must be backed up to a different region. How should the Architect meet this requirement?

  A. Create EBS snapshots directly from one region to another.
  B. Move the data to an Amazon S3 bucket and enable cross-region replication.
  C. Create EBS snapshots and then copy them to the desired region.
  D. Use a script to copy data from the current Amazon EBS volume to the destination Amazon EBS volume.
  C. Create EBS snapshots and then copy them to the desired region.
