Question # 65

A company wants to measure the effectiveness of its recent marketing campaigns. The company performs batch processing on csv files of sales data and stores the results in an Amazon S3 bucket once every hour. The S3 bi petabytes of objects. The company runs one-time queries in Amazon Athena to determine which products are most popular on a particular date for a particular region Queries sometimes fail or take longer than expected to finish.

Which actions should a solutions architect take to improve the query performance and reliability? (Select TWO.)

Reduce the S3 object sizes to less than 126 MB

Partition the data by date and region n Amazon S3

Store the files as large, single objects in Amazon S3.

Use Amazon Kinosis Data Analytics to run the Queries as pan of the batch processing operation

Use an AWS duo extract, transform, and load (ETL) process to convert the csv files into Apache Parquet format.

Question # 66

A company is launching a new gaming application. The company will use Amazon EC2 Auto Scaling groups to deploy the application. The application stores user data in a relational database.

The company has office locations around the world that need to run analytics on the user data in the database. The company needs a cost-effective database solution that provides cross-Region disaster recovery with low-latency read performance across AWS Regions.

Which solution will meet these requirements?

Create an Amazon ElastiCache for Redis cluster in the Region where the application is deployed. Create read replicas in Regions where the company offices are located. Ensure the company offices read from the read replica instances.

Create Amazon DynamoDB global tables. Deploy the tables to the Regions where the company offices are located and to the Region where the application is deployed. Ensure that each company office reads from the tables that are in the same Region as the office.

Create an Amazon Aurora global database. Configure the primary cluster to be in the Region where the application is deployed. Configure the secondary Aurora replicas to be in the Regions where the company offices are located. Ensure the company offices read from the Aurora replicas.

Create an Amazon RDS Multi-AZ DB cluster deployment in the Region where the application is deployed. Ensure the company offices read from read replica instances.

Question # 67

A company runs applications on AWS that connect to the company's Amazon RDS database. The applications scale on weekends and at peak times of the year. The company wants to scale the database more effectively for its applications that connect to the database.

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

Use Amazon DynamoDB with connection pooling with a target group configuration for the database. Change the applications to use the DynamoDB endpoint.

Use Amazon RDS Proxy with a target group for the database. Change the applications to use the RDS Proxy endpoint.

Use a custom proxy that runs on Amazon EC2 as an intermediary to the database. Change the applications to use the custom proxy endpoint.

Use an AWS Lambda function to provide connection pooling with a target group configuration for the database. Change the applications to use the Lambda function.

Question # 68

A company runs an application that uses Amazon RDS for PostgreSQL. The application receives traffic only on weekdays during business hours. The company wants to optimize costs and reduce operational overhead based on this usage.

Which solution will meet these requirements?

Use the Instance Scheduler on AWS to configure start and stop schedules.

Turn off automatic backups. Create weekly manual snapshots of the database.

Create a custom AWS Lambda function to start and stop the database based on minimum CPU utilization.

Purchase All Upfront reserved DB instances.

Question # 69

A company is deploying an application that processes large quantities of data in parallel. The company plans to use Amazon EC2 instances for the workload. The network architecture must be configurable to prevent groups of nodes from sharing the same underlying hardware.

Which networking solution meets these requirements?

Run the EC2 instances in a spread placement group.

Group the EC2 instances in separate accounts.

Configure the EC2 instances with dedicated tenancy.

Configure the EC2 instances with shared tenancy.

Question # 70

A gaming company is designing a highly available architecture. The application runs on a modified Linux kernel and supports only UDP-based traffic. The company needs the front-end tier to provide the best possible user experience. That tier must have low latency, route traffic to the nearest edge location, and provide static IP addresses for entry into the application endpoints.

What should a solutions architect do to meet these requirements?

Configure Amazon Route 53 to forward requests to an Application Load Balancer. Use AWS Lambda for the application in AWS Application Auto Scaling.

Configure Amazon CloudFront to forward requests to a Network Load Balancer. Use AWS Lambda for the application in an AWS Application Auto Scaling group.

Configure AWS Global Accelerator to forward requests to a Network Load Balancer. Use Amazon EC2 instances for the application in an EC2 Auto Scaling group.

Configure Amazon API Gateway to forward requests to an Application Load Balancer. Use Amazon EC2 instances for the application in an EC2 Auto Scaling group.

Question # 71

A company is running several business applications in three separate VPCs within me us-east-1 Region. The applications must be able to communicate between VPCs. The applications also must be able to consistently send hundreds to gigabytes of data each day to a latency-sensitive application that runs in a single on-premises data center.

A solutions architect needs to design a network connectivity solution that maximizes cost-effectiveness

Which solution moots those requirements?

Configure three AWS Site-to-Site VPN connections from the data center to AWS Establish connectivity by configuring one VPN connection for each VPC

Launch a third-party virtual network appliance in each VPC Establish an iPsec VPN tunnel between the Data center and each virtual appliance

Set up three AWS Direct Connect connections from the data center to a Direct Connect gateway in us-east-1 Establish connectivity by configuring each VPC to use one of the Direct Connect connections

Set up one AWS Direct Connect connection from the data center to AWS. Create a transit gateway, and attach each VPC to the transit gateway. Establish connectivity between the Direct Connect connection and the transit gateway.

Question # 72

A solutions architect needs to implement a solution to reduce a company's storage costs. All the company's data is in the Amazon S3 Standard storage class. The company must keep all data for at least 25 years. Data from the most recent 2 years must be highly available and immediately retrievable.

Which solution will meet these requirements?

Set up an S3 Lifecycle policy to transition objects to S3 Glacier Deep Archive immediately.

Set up an S3 Lifecycle policy to transition objects to S3 Glacier Deep Archive after 2 years.

Use S3 Intelligent-Tiering. Activate the archiving option to ensure that data is archived in S3 Glacier Deep Archive.

Set up an S3 Lifecycle policy to transition objects to S3 One Zone-Infrequent Access (S3 One Zone-IA) immediately and to S3 Glacier Deep Archive after 2 years.
