How can an image-hosting company ensure that all S3 objects in their AWS account remain private?

Single Choice

An image-hosting company stores its objects in Amazon S3 buckets. The company wants to avoid accidental exposure of the objects in the S3 buckets to the public. All S3 objects in the entire AWS account need to remain private.

Which solution will meet these requirements?

Use Amazon GuardDuty to monitor S3 bucket policies. Create an automatic remediation action rule that uses an AWS Lambda function to remediate any change that makes the objects public.

Use AWS Trusted Advisor to find publicly accessible S3 buckets. Configure email notifications in Trusted Advisor when a change is detected. Manually change the S3 bucket policy if it allows public access.

Use AWS Resource Access Manager to find publicly accessible S3 buckets. Use Amazon Simple Notification Service (Amazon SNS) to invoke an AWS Lambda function when a change is detected. Deploy a Lambda function that programmatically remediates the change.

Use the S3 Block Public Access feature on the account level. Use AWS Organizations to create a service control policy (SCP) that prevents IAM users from changing the setting. Apply the SCP to the account.

What AWS database solution and configuration should be used for near-real-time game statistics recording and displaying?

Single Choice

An online gaming company is designing a game that is expected to be popular all over the world. A solutions architect needs to define an AWS Cloud architecture that supports near-real-time recording and displaying of current game statistics for each player, along with the names of the top 25 players in the world, at any given time.

Which AWS database solution and configuration should the solutions architect use to meet these requirements?

Use Amazon RDS for MySQL as the data store for player activity. Configure the RDS DB instance for Multi-AZ support.

Use Amazon DynamoDB as the data store for player activity. Configure DynamoDB Accelerator (DAX) for the player data.

Use Amazon DynamoDB as the data store for player activity. Configure global tables in each required AWS Region for the player data.

Use Amazon RDS for MySQL as the data store for player activity. Configure cross-Region read replicas in each required AWS Region based on player proximity.

What is the most efficient solution for maintaining online and available student records across multiple AWS Regions?

Single Choice

An online learning company is migrating to the AWS Cloud. The company maintains its student records in a PostgreSQL database. The company needs a solution in which its data is available and online across multiple AWS Regions at all times.

Which solution will meet these requirements with the LEAST amount of operational overhead?

Migrate the PostgreSQL database to a PostgreSQL cluster on Amazon EC2 instances.

Migrate the PostgreSQL database to an Amazon RDS for PostgreSQL DB instance with the Multi-AZ feature turned on.

Migrate the PostgreSQL database to an Amazon RDS for PostgreSQL DB instance. Create a read replica in another Region.

Migrate the PostgreSQL database to an Amazon RDS for PostgreSQL DB instance. Set up DB snapshots to be copied to another Region.

What configuration should be recommended for an online photo application with free and paid services?

Single Choice

An online photo application lets users upload photos and perform image editing operations. The application offers two classes of service: free and paid. Photos submitted by paid users are processed before those submitted by free users. Photos are uploaded to Amazon S3 and the job information is sent to Amazon SQS.

Which configuration should a solutions architect recommend?

Use one SQS FIFO queue. Assign a higher priority to the paid photos so they are processed first.

Use two SQS FIFO queues: one for paid and one for free. Set the free queue to use short polling and the paid queue to use long polling.

Use two SQS standard queues: one for paid and one for free. Configure Amazon EC2 instances to prioritize polling for the paid queue over the free queue.

Use one SQS standard queue. Set the visibility timeout of the paid photos to zero. Configure Amazon EC2 instances to prioritize visibility settings so paid photos are processed first.

What is the most efficient solution to store a copy of photos in another location for an online photo-sharing company using Amazon S3?

Single Choice

An online photo-sharing company stores its photos in an Amazon S3 bucket that exists in the us-west-1 Region. The company needs to store a copy of all existing and new photos in another geographical location.

Which solution will meet this requirement with the LEAST operational effort?

Create a second S3 bucket in us-east-1. Enable S3 Cross-Region Replication from the existing S3 bucket to the second S3 bucket.

Create a cross-origin resource sharing (CORS) configuration of the existing S3 bucket. Specify us-east-1 in the CORS rule's AllowedOrigin element.

Create a second S3 bucket in us-east-1 across multiple Availability Zones. Create an S3 Lifecycle management rule to save photos into the second S3 bucket.

Create a second S3 bucket in us-east-1 to store the replicated photos. Configure S3 event notifications on object creation and update events that invoke an AWS Lambda function to copy photos from the existing S3 bucket to the second S3 bucket.

What application change should be recommended to resolve performance issues with an Amazon RDS Multi-AZ DB instance?

Single Choice

An online shopping application accesses an Amazon RDS Multi-AZ DB instance. Database performance is slowing down the application. After upgrading to the next-generation instance type, there was no significant performance improvement.

Analysis shows approximately 700 IOPS are sustained, common queries run for long durations and memory utilization is high.

Which application change should a solutions architect recommend to resolve these issues?

Migrate the RDS instance to an Amazon Redshift cluster and enable weekly garbage collection.

Separate the long-running queries into a new Multi-AZ RDS database and modify the application to query whichever database is needed.

Deploy a two-node Amazon ElastiCache cluster and modify the application to query the cluster first and query the database only if needed.

Create an Amazon Simple Queue Service (Amazon SQS) FIFO queue for common queries and query it first and query the database only if needed.

How can a solutions architect help the operations manager identify users with attached policies?

Single Choice

An operations team has a standard that states IAM policies should not be applied directly to users. Some new team members have not been following this standard. The operations manager needs a way to easily identify the users with attached policies.

What should a solutions architect do to accomplish this?

Monitor using AWS CloudTrail.

Create an AWS Config rule to run daily.

Publish IAM user changes to Amazon SNS.

Run AWS Lambda when a user is modified.

How can the performance of a production application running on Amazon RDS be improved for business reporting users?

Single Choice

Application developers have noticed that a production application is very slow when business reporting users run large production reports against the Amazon RDS instance backing the application. The CPU and memory utilization metrics for the RDS instance do not exceed 60% while the reporting queries are running. The business reporting users must be able to generate reports without affecting the application s performance.

Which action will accomplish this?

Increase the size of the RDS instance.

Create a read replica and connect the application to it.

Enable multiple Availability Zones on the RDS instance.

Create a read replica and connect the business reports to it.

How to support the storage and analysis needs of a growing application with multiple EC2 instances?

Single Choice

A product team is creating a new application that will store a large amount of data. The data will be analyzed hourly and modified by multiple Amazon EC2 Linux instances. The application team believes the amount of space needed will continue to grow for the next 6 months.

Which set of actions should a solutions architect take to support these needs?

Store the data in an Amazon EBS volume. Mount the EBS volume on the application instances.

Store the data in an Amazon EFS file system. Mount the file system on the application instances.

Store the data in Amazon S3 Glacier. Update the vault policy to allow access to the application instances.

Store the data in Amazon S3 Standard-Infrequent Access (S3 Standard-IA). Update the bucket policy to allow access to the application instances.
