Question # 57

A company is creating an application. The company stores data from tests of the application in multiple on-premises locations.

The company needs to connect the on-premises locations to VPCs in an AWS Region in the AWS Cloud. The number of accounts and VPCs will increase during the next year. The network architecture must simplify the administration of new connections and must provide the ability to scale.

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

Create a peering connection between the VPCs. Create a VPN connection between the VPCs and the on-premises locations.

Launch an Amazon EC2 instance. On the instance, include VPN software that uses a VPN connection to connect all VPCs and on-premises locations.

Create a transit gateway. Create VPC attachments for the VPC connections. Create VPNattachments for the on-premises connections.

Create an AWS Direct Connect connection between the on-premises locations and a central VPC. Connect the central VPC to other VPCs by using peering connections.

Question # 58

A company hosts an application on AWS that uses an Amazon S3 bucket and an Amazon Aurora database. The company wants to implement a multi-Region disaster recovery (DR) strategy that minimizes potential data loss.

Which solution will meet these requirements?

Create an Aurora read replica in a second Availability Zone within the same AWS Region. Enable S3 Versioning for the bucket.

Create an Aurora read replica in a second AWS Region. Configure AWS Backup to create continuous backups of the S3 bucket to a second bucket in a second Availability Zone.

Enable Aurora native database backups across multiple AWS Regions. Use S3 cross-account backups within the company's local Region.

Migrate the database to an Aurora global database. Create a second S3 bucket in a second Region. Configure Cross-Region Replication.

Question # 59

A solutions architect needs to optimize a large data analytics job that runs on an Amazon EMR cluster. The job takes 13 hours to finish. The cluster has multiple core nodes and worker nodes deployed on large, compute-optimized instances.

After reviewing EMR logs, the solutions architect discovers that several nodes are idle for more than 5 hours while the job is running. The solutions architect needs to optimize cluster performance.

Which solution will meet this requirement MOST cost-effectively?

Increase the number of core nodes to ensure there is enough processing power to handle the analytics job without any idle time.

Use the EMR managed scaling feature to automatically resize the cluster based on workload.

Migrate the analytics job to a set of AWS Lambda functions. Configure reserved concurrency for the functions.

Migrate the analytics job core nodes to a memory-optimized instance type to reduce the total job runtime.

Question # 60

A company is deploying a new application to a VPC on existing Amazon EC2 instances. The application has a presentation tier that uses an Auto Scaling group of EC2 instances. The application also has a database tier that uses an Amazon RDS Multi-AZ database.

The VPC has two public subnets that are split between two Availability Zones. A solutions architect adds one private subnet to each Availability Zone for the RDS database. The solutions architect wants to restrict network access to the RDS database to block access from EC2 instances that do not host the new application.

Which solution will meet this requirement?

Modify the RDS database security group to allow traffic from a CIDR range that includes IP addresses of the EC2 instances that host the new application.

Associate a new ACL with the private subnets. Deny all incoming traffic from IP addresses that belong to any EC2 instance that does not host the new application.

Modify the RDS database security group to allow traffic from the security group that is associated with the EC2 instances that host the new application.

Associate a new ACL with the private subnets. Deny all incoming traffic except for traffic from a CIDR range that includes IP addresses of the EC2 instances that host the new application.

Question # 61

A company hosts an application on AWS that gives users the ability to download photos. The company stores all photos in an Amazon S3 bucket that is located in the us-east-1 Region. The company wants to provide the photo download application to global customers with low latency.

Which solution will meet these requirements?

Find the public IP addresses that Amazon S3 uses in us-east-1. Configure an Amazon Route 53 latency-based routing policy that routes to all the public IP addresses.

Configure an Amazon CloudFront distribution in front of the S3 bucket. Use the distribution endpoint to access the photos that are in the S3 bucket.

Configure an Amazon Route 53 geoproximity routing policy to route the traffic to the S3 bucket that is closest to each customer's location.

Create a new S3 bucket in the us-west-1 Region. Configure an S3 Cross-Region Replication rule to copy the photos to the new S3 bucket.

Question # 62

A gaming company hosts a browser-based application on AWS. The users of the application consume a large number of videos and images that are stored in Amazon S3. This content is the same for all users.

The application has increased in popularity, and millions of users worldwide are accessing these media files. The company wants to provide the files to the users while reducing the load on the origin.

Which solution meets these requirements MOST cost-effectively?

Deploy an AWS Global Accelerator accelerator in front of the web servers.

Deploy an Amazon CloudFront web distribution in front of the S3 bucket.

Deploy an Amazon ElastiCache (Redis OSS) instance in front of the web servers.

Deploy an Amazon ElastiCache (Memcached) instance in front of the web servers.

Question # 63

A company is designing a web application with an internet-facing Application Load Balancer (ALB).

The company needs the ALB to receive HTTPS web traffic from the public internet. The ALB must send only HTTPS traffic to the web application servers hosted on the Amazon EC2 instances on port 443. The ALB must perform a health check of the web application servers over HTTPS on port 8443.

Which combination of configurations of the security group that is associated with the ALB will meet these requirements? (Select THREE.)

Allow HTTPS inbound traffic from 0.0.0.0/0 for port 443.

Allow all outbound traffic to 0.0.0.0/0 for port 443.

Allow HTTPS outbound traffic to the web application instances for port 443.

Allow HTTPS inbound traffic from the web application instances for port 443.

Allow HTTPS outbound traffic to the web application instances for the health check on port 8443.

Allow HTTPS inbound traffic from the web application instances for the health check on port 8443.

Question # 64

A company's reporting system delivers hundreds of .csv files to an Amazon S3 bucket each day. The company must convert these files to Apache Parquet format and must store the files in a transformed data bucket.

Which solution will meet these requirements with the LEAST development effort?

Create an Amazon EMR cluster with Apache Spark installed. Write a Spark application to transform the data. Use EMR File System (EMRFS) to write files to the transformed data bucket.

Create an AWS Glue crawler to discover the data. Create an AWS Glue extract, transform, and load (ETL) job to transform the data. Specify the transformed data bucket in the output step.

Use AWS Batch to create a job definition with Bash syntax to transform the data and output the data to the transformed data bucket. Use the job definition to submit a job. Specify an array job as the job type.

Create an AWS Lambda function to transform the data and output the data to the transformed data bucket. Configure an event notification for the S3 bucket. Specify the Lambda function as the destination for the event notification.
