Amazon SAA-C01 Online Questions & Answers

• Question 91:

  A Solutions Architect has been asked to deliver video content stored on Amazon S3 to specific users from Amazon CloudFront while restricting access by unauthorized users. How can the Architect implement a solution to meet these requirements?

  C. Use Amazon S3 static website as the origin of CloudFront, and configure CloudFront to deliver the videos by generating a signed URL for users.
  D. Use OAI for CloudFront to access private S3 objects and select the Restrict Viewer Access option in CloudFront cache behavior to use signed URLs.
  B. Store the videos as private objects in Amazon S3, and let CloudFront serve the objects by using only Origin Access Identity (OAI).

• Question 92:

  A Solutions Architect is designing a service that must have four Amazon EC2 instances running between 8 AM and 6 PM daily. The service requires one EC2 instance outside of those hours. What is the MOST cost-effective way to provide enough compute?

  A. Use one Amazon EC2 Reserved Instance and use an Auto Scaling group to add and remove EC2 instances based on CPU utilization.
  B. Use one Amazon EC2 On-Demand instance and use an Auto Scaling group to add and remove EC2 instances based on CPU utilization.
  C. Use one Amazon EC2 On-Demand instance and use an Auto Scaling Group scheduled action to add three EC2 Spot instances at 7:30 AM and remove three instances at 6:10 PM.
  D. Use one Amazon EC2 Reserved Instance and use an Auto Scaling Group scheduled action to add three EC2 On-Demand instances at 7:30 AM and remove three instances at 6:10 PM.
  B. Use one Amazon EC2 On-Demand instance and use an Auto Scaling group to add and remove EC2 instances based on CPU utilization.

• Question 93:

  An application is running on Amazon EC2 instances behind an Application Load Balancer. The instances run in an Auto Scaling group across multiple Availability Zones. Four instances are required to handle a predictable traffic load. The Solutions Architect wants to ensure that the operation is fault-tolerant up to the loss of one Availability Zone.

  Which is the MOST cost-efficient way to meet these requirements?

  A. Deploy two instances in each of three Availability Zones.
  B. Deploy two instances in each of two Availability Zones.
  C. Deploy four instances in each of two Availability Zones.
  D. Deploy one instance in each of three Availability Zones.
  A. Deploy two instances in each of three Availability Zones.

• Question 94:

  A team has an application that detects new objects being uploaded into an Amazon S3 bucket. The uploads trigger a Lambda function to write object metadata into an Amazon DynamoDB table and RDS PostgreSQL database. Which action should the team take to ensure high availability?

  A. Enable cross-region replication in the Amazon S3 bucket.
  B. Create a Lambda function for each Availability Zone the application is deployed in.
  C. Enable multi-AZ on the RDS PostgreSQL database.
  D. Create a DynamoDB stream for the DynamoDB table.
  D. Create a DynamoDB stream for the DynamoDB table.

• Question 95:

  A Solutions Architect must design an Amazon DynamoDB table to store data about customer activities. The data is used to analyze recent customer behavior, so data that is less than a week old is heavily accessed and older data is accessed infrequently. Data that is more than one month old never needs to be referenced by the application, but needs to be archived for year-end analytics.

  What is the MOST cost-efficient way to meet these requirements? (Choose two.)

  A. Use DynamoDB time-to-live settings to expire items after a certain time period.
  B. Provision a higher write capacity unit to minimize the number of partitions.
  C. Create separate tables for each week's data with higher throughput for the current week.
  D. Pre-process data to consolidate multiple records to minimize write operations.
  E. Export the old table data from DynamoDB to Amazon S3 using AWS Data Pipeline, and delete the old table.
  B. Provision a higher write capacity unit to minimize the number of partitions.
  C. Create separate tables for each week's data with higher throughput for the current week.

• Question 96:

  A client notices that their engineers often make mistakes when creating Amazon SQS queues for their backend system. Which action should a Solutions Architect recommend to improve this process?

  A. Use the AWS CLI to create queues using AWS IAM Access Keys.
  B. Write a script to create the Amazon SQS queue using AWS Lambda.
  C. Use AWS Elastic Beanstalk to automatically create the Amazon SQS queues.
  D. Use AWS CloudFormation Templates to manage the Amazon SQS queue creation.
  D. Use AWS CloudFormation Templates to manage the Amazon SQS queue creation.

• Question 97:

  A Solution Architect is designing a disaster recovery solution for a 5 TB Amazon Redshift cluster. The recovery site must be at least 500 miles (805 kilometers) from the live site. How should the Architect meet these requirements?

  A. Use AWS CloudFormation to deploy the cluster in a second region.
  B. Take a snapshot of the cluster and copy it to another Availability Zone.
  C. Modify the Redshift cluster to span two regions.
  D. Enable cross-region snapshots to a different region.
  D. Enable cross-region snapshots to a different region.

• Question 98:

  A company has a web application that makes requests to a backend API service. The API service is behind an Elastic Load Balancer running on Amazon EC2 instances.

  Most backend API service endpoint calls finish very quickly, but one endpoint that makes calls to create objects in an external service takes a long time to complete. These long-running calls are causing client timeouts and increasing overall

  system latency.

  What should be done to minimize the system throughput impact of the slow-running endpoint?

  A. Change the EC2 instance size to increase memory and compute capacity.
  B. Use Amazon SQS to offload the long-running requests for asynchronous processing by seprate workers.
  C. Increase the load balancer idle timeount to allow the long-running requests to complete.
  D. Use Amazon ElastiCache for Redis to cache responses from the external service.
  D. Use Amazon ElastiCache for Redis to cache responses from the external service.

• Question 99:

  A Solutions Architect is designing a high-performance computing job that runs on Amazon EC2 instances in private subnets. To allow the application to download patches, the infrastructure must be altered to allow the instances to access external endpoints. Any changes to the infrastructure must involve minimal ongoing systems management effort.

  What will allow the EC2 instances to access the endpoint while meeting these requirements?

  A. NAT gateway
  B. Elastic IP address
  C. AWS Direct Connect
  D. Virtual private gateway
  A. NAT gateway

• Question 100:

  A Solutions Architect is deploying a new production MySQL database on AWS. It is critical that the database is highly available. What should the Architect do to achieve this goal with Amazon RDS?

  A. Create a read replica of the primary database and deploy it in a different AWS Region.
  B. Enable multi-AZ to create a standby database in a different Availability Zone.
  C. Enable multi-AZ to create a standby database in a different AWS Region.
  D. Create a read replica of the primary database and deploy it in a different Availability Zone.
  A. Create a read replica of the primary database and deploy it in a different AWS Region.
