AWS Certified Solutions Architect - Professional Questions and Answers

Question 121

Question:

A company has an application that stores user-uploaded videos in an Amazon S3 bucket using S3 Standard storage. Users access videos frequently for the first 180 days, and rarely after that. Most videos are over 100 MB. Users often have poor internet connectivity, and the company uses multipart uploads.

A solutions architect needs tooptimize S3 storage costs.

Which combination of actions will meet these requirements? (Select TWO.)

Options:

A.

Configure the S3 bucket to be a Requester Pays bucket.

B.

Use S3 Transfer Acceleration to upload the videos.

C.

Create a lifecycle rule to expireincomplete multipart uploadsafter 7 days.

D.

Create a lifecycle rule to transition objects toS3 Glacier Instant Retrieval after 1 day.

E.

Create a lifecycle rule to transition objects toS3 Standard-IA after 180 days.

Question 122

A finance company is running its business-critical application on current-generation Linux EC2 instances The application includes a self-managed MySQL database performing heavy I/O operations. The application is working fine to handle a moderate amount of traffic during the month. However, it slows down during the final three days of each month due to month-end reporting, even though the company is using Elastic Load Balancers and Auto Scaling within its infrastructure to meet the increased demand.

Which of the following actions would allow the database to handle the month-end load with the LEAST impact on performance?

Options:

A.

Pre-warming Elastic Load Balancers, using a bigger instance type, changing all Amazon EBS volumes to GP2 volumes.

B.

Performing a one-time migration of the database cluster to Amazon RDS. and creatingseveral additional read replicas to handle the load during end of month

C.

Using Amazon CioudWatch with AWS Lambda to change the type. size, or IOPS of Amazon EBS volumes in the cluster based on a specific CloudWatch metric

D.

Replacing all existing Amazon EBS volumes with new PIOPS volumes that have the maximum available storage size and I/O per second by taking snapshots before the end of the month and reverting back afterwards.

Question 123

A company needs to optimize the cost of its application on AWS. The application uses AWS Lambda functions and Amazon ECS containers that run on AWS Fargate. The application is write-heavy and stores data in an Amazon Aurora MySQL database.

The load on the application is not consistent. The application experiences long periods of no usage, followed by sudden and significant increases and decreases in traffic. The database runs on a memory optimized DB instance and has high utilization during peak times. A solutions architect must design a solution that can scale to handle the changes in traffic.

Which solution will meet these requirements MOST cost-effectively?

Options:

A.

Add additional read replicas to the database. Purchase Instance Savings Plans and reserved DB instances for Aurora.

B.

Migrate the database to an Aurora DB cluster that has multiple writer instances. Purchase Instance Savings Plans.

C.

Migrate the database to an Aurora global database. Purchase Compute Savings Plans and reserved DB instances for Aurora.

D.

Migrate the database to Aurora Serverless v2. Purchase Compute Savings Plans.

Question 124

A research company is running daily simul-ations in the AWS Cloud to meet high demand. The simu-lations run on several hundred Amazon EC2 instances that are based on Amazon Linux 2. Occasionally, a simu-lation gets stuck and requires a cloud operations engineer to solve the problem by connecting to an EC2 instance through SSH.

Company policy states that no EC2 instance can use the same SSH key and that all connections must be logged in AWS CloudTrail.

How can a solutions architect meet these requirements?

Options:

A.

Launch new EC2 instances, and generate an individual SSH key for each instance. Store the SSH key in AWS Secrets Manager. Create a new IAM policy, and attach it tothe engineers' IAM role with an Allow statement for the GetSecretValue action. Instruct the engineers to fetch the SSH key from Secrets Manager when they connect through any SSH client.

B.

Create an AWS Systems Manager document to run commands on EC2 instances to set a new unique SSH key. Create a new IAM policy, and attach it to the engineers' IAM role with an Allow statement to run Systems Manager documents. Instruct the engineers to run the document to set an SSH key and to connect through any SSH client.

C.

Launch new EC2 instances without setting up any SSH key for the instances. Set up EC2 Instance Connect on each instance. Create a new IAM policy, and attach it to the engineers' IAM role with an Allow statement for the SendSSHPublicKey action. Instruct the engineers to connect to the instance by using a browser-based SSH client from the EC2 console.

D.

Set up AWS Secrets Manager to store the EC2 SSH key. Create a new AWS Lambda function to create a new SSH key and to call AWS Systems Manager Session Manager to set the SSH key on the EC2 instance. Configure Secrets Manager to use the Lambda function for automatic rotation once daily. Instruct the engineers to fetch the SSH key from Secrets Manager when they connect through any SSH client.
