Question#51

A company runs a website on Amazon EC2 instances behind an ELB Application Load Balancer. Amazon Route 53 is used for the DNS. The company wants to set up a backup website with a message including a phone number and email address that users can reach if the primary website is down.
How should the company deploy this solution?

  • A. Use Amazon S3 website hosting for the backup website and Route 53 failover routing policy.
  • B. Use Amazon S3 website hosting for the backup website and Route 53 latency routing policy.
  • C. Deploy the application in another AWS Region and use ELB health checks for failover routing.
  • D. Deploy the application in another AWS Region and use server-side redirection on the primary website.

Question#52

A media company is evaluating the possibility of moving its systems to the AWS Cloud. The company needs at least 10 TB of storage with the maximum possible
I/O performance for video processing, 300 TB of very durable storage for storing media content, and 900 TB of storage to meet requirements for archival media that is not in use anymore.
Which set of services should a solutions architect recommend to meet these requirements?

  • A. Amazon Elastic Block Store (Amazon EBS) for maximum performance, Amazon S3 for durable data storage, and Amazon S3 Glacier for archival storage
  • B. Amazon Elastic Block Store (Amazon EBS) for maximum performance, Amazon Elastic File System (Amazon EFS) for durable data storage, and Amazon S3 Glacier for archival storage
  • C. Amazon EC2 instance store for maximum performance, Amazon Elastic File System (Amazon EFS) for durable data storage, and Amazon S3 for archival storage
  • D. Amazon EC2 instance store for maximum performance, Amazon S3 for durable data storage, and Amazon S3 Glacier for archival storage

Question#53

A company uses Amazon S3 as its object storage solution. The company has thousands of S3 buckets it uses to store data. Some of the S3 buckets have data that is accessed less frequently than others. A solutions architect found that lifecycle policies are not consistently implemented or are implemented partially, resulting in data being stored in high-cost storage.
Which solution will lower costs without compromising the availability of objects?

  • A. Use S3 ACLs.
  • B. Use Amazon Elastic Block Store (Amazon EBS) automated snapshots.
  • C. Use S3 Intelligent-Tiering storage.
  • D. Use S3 One Zone-Infrequent Access (S3 One Zone-IA).

Question#54

An application is running on Amazon EC2 instances. Sensitive information required for the application is stored in an Amazon S3 bucket. The bucket needs to be protected from internet access while only allowing services within the VPC access to the bucket.
Which combination of actions should solutions archived take to accomplish this? (Choose two.)

  • A. Create a VPC endpoint for Amazon S3.
  • B. Enable server access logging on the bucket.
  • C. Apply a bucket policy to restrict access to the S3 endpoint.
  • D. Add an S3 ACL to the bucket that has sensitive information.
  • E. Restrict users using the IAM policy to use the specific bucket.

Question#55

A web application runs on Amazon EC2 instances behind an Application Load Balancer. The application allows users to create custom reports of historical weather data. Generating a report can take up to 5 minutes. These long-running requests use many of the available incoming connections, making the system unresponsive to other users.
How can a solutions architect make the system more responsive?

  • A. Use Amazon SQS with AWS Lambda to generate reports.
  • B. Increase the idle timeout on the Application Load Balancer to 5 minutes.
  • C. Update the client-side application code to increase its request timeout to 5 minutes.
  • D. Publish the reports to Amazon S3 and use Amazon CloudFront for downloading to the user.

Question#56

A solutions architect must create a highly available bastion host architecture. The solution needs to be resilient within a single AWS Region and should require only minimal effort to maintain.
What should the solutions architect do to meet these requirements?

  • A. Create a Network Load Balancer backed by an Auto Scaling group with a UDP listener.
  • B. Create a Network Load Balancer backed by a Spot Fleet with instances in a partition placement group.
  • C. Create a Network Load Balancer backed by the existing servers in different Availability Zones as the target.
  • D. Create a Network Load Balancer backed by an Auto Scaling group with instances in multiple Availability Zones as the target.

Question#57

A three-tier web application processes orders from customers. The web tier consists of Amazon EC2 instances behind an Application Load Balancer, a middle tier of three EC2 instances decoupled from the web tier using Amazon SQS, and an Amazon DynamoDB backend. At peak times, customers who submit orders using the site have to wait much longer than normal to receive confirmations due to lengthy processing times. A solutions architect needs to reduce these processing times.
Which action will be MOST effective in accomplishing this?

  • A. Replace the SQS queue with Amazon Kinesis Data Firehose.
  • B. Use Amazon ElastiCache for Redis in front of the DynamoDB backend tier.
  • C. Add an Amazon CloudFront distribution to cache the responses for the web tier.
  • D. Use Amazon EC2 Auto Scaling to scale out the middle tier instances based on the SQS queue depth.

Question#58

A company relies on an application that needs at least 4 Amazon EC2 instances during regular traffic and must scale up to 12 EC2 instances during peak loads.
The application is critical to the business and must be highly available.
Which solution will meet these requirements?

  • A. Deploy the EC2 instances in an Auto Scaling group. Set the minimum to 4 and the maximum to 12, with 2 in Availability Zone A and 2 in Availability Zone B.
  • B. Deploy the EC2 instances in an Auto Scaling group. Set the minimum to 4 and the maximum to 12, with all 4 in Availability Zone A.
  • C. Deploy the EC2 instances in an Auto Scaling group. Set the minimum to 8 and the maximum to 12, with 4 in Availability Zone A and 4 in Availability Zone B.
  • D. Deploy the EC2 instances in an Auto Scaling group. Set the minimum to 8 and the maximum to 12, with all 8 in Availability Zone A.

Question#59

A solutions architect must design a solution for a persistent database that is being migrated from on-premises to AWS. The database requires 64,000 IOPS according to the database administrator. If possible, the database administrator wants to use a single Amazon Elastic Block Store (Amazon EBS) volume to host the database instance.
Which solution effectively meets the database administrator's criteria?

  • A. Use an instance from the I3 I/O optimized family and leverage local ephemeral storage to achieve the IOPS requirement.
  • B. Create a Nitro-based Amazon EC2 instance with an Amazon Elastic Block Store (Amazon EBS) Provisioned IOPS SSD (io1) volume attached. Configure the volume to have 64,000 IOPS.
  • C. Create and map an Amazon Elastic File System (Amazon EFS) volume to the database instance and use the volume to achieve the required IOPS for the database.
  • D. Provision two volumes and assign 32,000 IOPS to each. Create a logical volume at the operating system level that aggregates both volumes to achieve the IOPS requirements.
