Question 347

A company hosts a frontend application that uses an Amazon API Gateway API backend that is integrated with AWS Lambda When the API receives requests, the Lambda function loads many libranes Then the Lambda function connects to an Amazon RDS database processes the data and returns the data to the frontend application. The company wants to ensure that response latency is as low as possible for all its users with the fewest number of changes to the company's operations Which solution will meet these requirements'?

A.

Establish a connection between the frontend application and the database to make queries faster by bypassing the API

B.

Configure provisioned concurrency for the Lambda function that handles the requests

C.

Cache the results of the queries in Amazon S3 for faster retneval of similar datasets.

D.

Increase the size of the database to increase the number of connections Lambda can establish at one time

Question 348

A company plans to use Amazon ElastiCache for its multi-tier web application A solutions architect creates a Cache VPC for the ElastiCache cluster and an App VPC for the application's Amazon EC2 instances Both VPCs are in the us- east-1 Region The solutions architect must implement a solution to provide tne application's EC2 instances with access to the ElastiCache cluster Which solution will meet these requirements MOST cost-effectively?

A.

Create a peering connection between the VPCs Add a route table entry for the peering connection in both VPCs Configure an inbound rule for the ElastiCache cluster's security group to allow inbound connection from the application's security group

B.

Create a Transit VPC Update the VPC route tables in the Cache VPC and the App VPC to route traffic through the Transit VPC Configure an inbound rule for the ElastiCache cluster's security group to allow inbound connection from the application's security group

C.

Create a peering connection between the VPCs Add a route table entry for the peering connection in both VPCs Configure an inbound rule for the peering connection's security group to allow inbound connection from the application's secunty group

Question 349

A company has an application that places hundreds of .csv files into an Amazon S3 bucket every hour. The files are 1 GB in size. Each time a file is uploaded, the company needs to convert the file to Apache Parquet format and place the output file into an S3 bucket. Which solution will meet these requirements with the LEAST operational overhead?

C.

Create an AWS Glue table and an AWS Glue crawler for the S3 bucket where the application places the .csv files. Schedule an AWS Lambda function to periodically use Amazon Athena to query the AWS Glue table, convert the query results into Parquet format, and place the output files into an S3 bucket.

D.

Create an AWS Glue extract, transform, and load (ETL) job to convert the .csv files to Parquet format and place the output files into an S3 bucket. Create an AWS Lambda function for each S3 PUT event to invoke the ETL job.

Question 350

A company runs a web application on Amazon EC2 instances in multiple Availability Zones. The EC2 instances are in private subnets. A solutions architect implements an internet-facing Application Load Balancer (ALB) and specifies the EC2 instances as the target group. However, the internet traffic is not reaching the EC2 instances.

How should the solutions architect reconfigure the architecture to resolve this issue?

A.

Replace the ALB with a Network Load Balancer. Configure a NAT gateway in a public subnet to allow internet traffic.

B.

Move the EC2 instances to public subnets. Add a rule to the EC2 instances’ security groups to allow outbound traffic to 0.0.0.0/0.

C.

Update the route tables for the EC2 instances’ subnets to send 0.0.0.0/0 traffic through the internet gateway route. Add a rule to the EC2 instances’ security groups to allow outbound traffic to 0.0.0.0/0.

D.

Create public subnets in each Availability Zone. Associate the public subnets with the ALB. Update the route tables for the public subnets with a route to the private subnets.
