Amazon SAA-C01 Online Questions & Answers

• Question 171:

  A company runs a legacy application with a single-tier architecture on an Amazon EC2 instance. Disk I/O is low, with occasional small spikes during business hours. The company requires the instance to be stopped from 8 PM to 8 AM daily. Which storage option is MOST appropriate for this workload?

  A. Amazon EC2 instance storage
  B. Amazon EBS General Purpose SSD (gp2) storage
  C. Amazon S3
  D. Amazon EBS Provision IOPS SSD (io1) storage
  C. Amazon S3

• Question 172:

  A web application running on Amazon EC2 instances writes data synchronously to an Amazon DynamoDB table configured for 60 write capacity units. During normal operation the application writes 50 KB/s to the tale, but can scale up to 500 KB/ s during peak hours. The application is currently throttling errors from the DynamoDB table during peak hours.

  What is the MOST cost-efficient change to support the increased traffic with minimal changes to the application?

  A. Use Amazon SQS to manage the write operations to the DynamoDB table.
  B. Change DynamoDB table configuration to 600 write capacity units.
  C. Increase the number of Amazon EC2 instances to support the traffic.
  D. Configure Amazon DynamoDB Auto Scaling to handle the extra demand.
  D. Configure Amazon DynamoDB Auto Scaling to handle the extra demand.

• Question 173:

  A company is storing data in an Amazon DynamoDB table and needs to take daily backups and retain them for 6 months. How should the Solutions Architect meet these requirements without impacting the production workload?

  A. Use DynamoDB replication and restore the table from the replica
  B. Use AWS Data Pipeline and create a scheduled job to back up the DynamoDB table daily
  C. Use Amazon CloudWatch Events to trigger an AWS Lambda function that makes an on-demand backup of the table
  D. Use AWS Batch to create a scheduled backup with the default template, then back up to Amazon S3 daily.
  D. Use AWS Batch to create a scheduled backup with the default template, then back up to Amazon S3 daily.

• Question 174:

  A company processed 10 TB of raw data to generate quarterly reports. Although it is unlikely to be used again, the raw data needs to be preserved for compliance and auditing purposes. What is the MOST cost-effective way to store the data in AWS?

  A. Amazon EBS Cold HDD (sc1)
  B. Amazon S3 One Zone-Infrequent Access (S3 One Zone-IA)
  C. Amazon S3 Standard-Infrequent Access (S3 Standard-IA)
  D. Amazon Glacier
  C. Amazon S3 Standard-Infrequent Access (S3 Standard-IA)

• Question 175:

  A Solutions Architect is designing a multi-tier application consisting of an Application Load Balancer, an Amazon RDS database instance, and an Auto Scaling group on Amazon EC2 instances. Each tier is in a separate subnet. There are some EC2 instances in the subnet that belong to another application. The RDS database instance should accept traffic only from the EC2 instances in the Auto Scaling group.

  What should be done to meet these requirements?

  A. Configure the inbound network ACLs on the database subnet to accept traffic from the IP addresses of the EC2 instances only.
  B. Configure the inbound rules on the security group associated with the RDS database instance. Set the source to the security group associated with instances in the Auto Scaling group.
  C. Configure the outbound rules on the security group associated with the Auto Scaling group. Set the destination to the security group associated with the RDS database instance.
  D. Configure the inbound network ACLs on the database subnet to accept traffic only from the CIDR range of the subnet used by the Auto Scaling group.
  C. Configure the outbound rules on the security group associated with the Auto Scaling group. Set the destination to the security group associated with the RDS database instance.

• Question 176:

  A Solutions Architect is developing a solution for sharing files in an organization. The solution must allow multiple users to access the storage service at once from different virtual machines and scale automatically. It must also support file-level locking.

  Which storage service meets the requirements of this use case?

  A. Amazon S3
  B. Amazon EFS
  C. Amazon EBS
  D. Cached Volumes
  B. Amazon EFS

• Question 177:

  A company is launching a static website using the zone apex (mycompany.com). The company wants to use Amazon Route 53 for DNS. Which steps should the company perform to implement a scalable and cost-effective solution? (Choose two.)

  A. Host the website on an Amazon EC2 instance with ELB and Auto Scaling, and map a Route 53 alias record to the ELB endpoint.
  B. Host the website using AWS Elastic Beanstalk, and map a Route 53 alias record to the Beanstalk stack.
  C. Host the website on an Amazon EC2 instance, and map a Route 53 alias record to the public IP address of the Amazon EC2 instance.
  D. Serve the website from an Amazon S3 bucket, and map a Route 53 alias record to the website endpoint.
  E. Create a Route 53 hosted zone, and set the NS records of the domain to use Route 53 name servers.
  C. Host the website on an Amazon EC2 instance, and map a Route 53 alias record to the public IP address of the Amazon EC2 instance.
  D. Serve the website from an Amazon S3 bucket, and map a Route 53 alias record to the website endpoint.

• Question 178:

  A Solutions Architect is designing a VPC. Instances in a private subnet must be able to establish IPv6 traffic to the Internet. The design must scale automatically and not incur any additional cost. This can be accomplished with:

  A. an egress-only internet gateway
  B. a NAT gateway
  C. a custom NAT instance
  D. a VPC endpoint
  A. an egress-only internet gateway

• Question 179:

  A Solution Architect is designing a three-tier web application. The Architect wants to restrict access to the database tier to accept traffic from the application servers only. However, these application servers are in an Auto Scaling group and may vary in quantity.

  How should the Architect configure the database servers to meet the requirements?

  A. Configure the database security group to allow database traffic from the application server IP addresses.
  B. Configure the database security group to allow database traffic from the application server security group.
  C. Configure the database subnet network ACL to deny all inbound non-database traffic from the application-tier subnet.
  D. Configure the database subnet network ACL to allow inbound database traffic from the application-tier subnet.
  C. Configure the database subnet network ACL to deny all inbound non-database traffic from the application-tier subnet.

• Question 180:

  A Solutions Architect must select the most cost-efficient architecture for a service that responds to web requests. These web requests are small and query a DynamoDB table. The request rate ranges from zero to several hundred each second, without any predictable patterns.

  What is the MOST cost-efficient architecture for this service?

  A. Network Load Balancer/Amazon EC2
  B. Application Load Balancer/Amazon ECS
  C. API Gateway/AWS Lambda
