Question 1

A company is running a serverless application that consists of several AWS Lambda functions and Amazon

DynamoDB tables. The company has created new functionality that requires the Lambda functions to access

an Amazon Neptune DB cluster The Neptune DB cluster is located in three subnets in a VPC.

Which of the possible solutions will allow the Lambda functions to access the Neptune DB cluster and

DynamoDB tables? (Select TWO )

A : Create three public subnets in the Neptune VPC and route traffic through an interne: gateway Host theLambda functions m the three new public subnets

B : Create three private subnets in the Neptune VPC and route internet traffic through a NAT gateway Hostthe Lambda functions In the three new private subnets.

C : Host the Lambda functions outside the VPC. Update the Neptune security group to allow access fromthe IP ranges of the Lambda functions.

D : Host the Lambda functions outside the VPC. Create a VPC endpoint for the Neptune database, and havethe Lambda functions access Neptune over the VPC endpoint

E : Create three private subnets in the Neptune VPC. Host the Lambda functions m the three new isolatedsubnets. Create a VPC endpoint for DynamoDB. and route DynamoDB traffic to the VPC endpoint

Answer: A,C

Question 2

An insurance company collects contributions from its clients and invests them in the stock market. Using the on-premises data center, the company ingests raw data feeds from the stock market, transforms it, and sends it to the internal Apache Kafka cluster for processing. The management wants to send the cluster’s output to Amazon Web Services by building a scalable and near-real-time solution that will provide the stock market data to its web application. The application is a critical production component so the solution needs to have a consistent high-performance network.

Which of the following actions should the solutions architect implement to fulfill the requirements? (Select THREE.)

A : ite a Lambda function to process the Amazon Kinesis data stream and create a WebSocket API in Amazon API Gateway to invoke the function. Send the callback messages to connected clients by using the @connections command for the API.

B : tch the messages from the on-premises Apache Kafka cluster by using a fleet of EC2 instances in an Auto Scaling Group. Send the data into an Amazon Kinesis Data Stream by using Amazon Kinesis Consumer Library.

C : ll the messages from the on-premises Apache Kafka cluster by using a fleet of Amazon EC2 instances in an Auto Scaling Group. Send the data into an Amazon Kinesis Data Stream by using Amazon Kinesis Producer Library.

D : have a consistent performance while being cost-effective, configure a Site-to-Site VPN from the on-premises data center to the AWS VPC.

E : have consistent performance, request for an AWS Direct Connect connection from the on-premises data center to the AWS VPC.

F : ite a Lambda function to process the Amazon Kinesis data stream and write a GraphQL API in AWS AppSync to invoke the function. Send the callback messages to connected clients by using the @connections command for the API.

Answer: A,C

Question 3

A company is building an innovative AI-powered traffic monitoring portal and uses AWS to host its cloud infrastructure. For the initial deployment, the application would be used by an entire city. The application should be highly available and fault-tolerant to avoid unnecessary downtime.

Which of the following options is the MOST suitable architecture that you should implement?

A : unch an Auto Scaling group of EC2 instances on three Availability Zones. Attach an application load balancer to the Auto Scaling Group. Use an Amazon Aurora Multi-Master as the database tier. Use Route 53 and create an Alias record to point to the ELB.

B : DynamoDB as the database of the portal. Launch an Auto Scaling group of EC2 instances on four Availability Zones. Attach an application load balancer to the Auto Scaling Group. Use Route 53 and create an A record to point to the ELB.

C : ElastiCache for the database caching of the portal. Launch an Auto Scaling group of EC2 instances on four Availability Zones. Attach an application load balancer to the Auto Scaling Group. Use a MySQL RDS instance with Multi-AZ deployments configuration and Read Replicas. Use Route 53 and create a CNAME to point to the ELB.

D : unch an Auto Scaling group of EC2 instances on two Availability Zones. Attach an application load balancer to the Auto Scaling Group. Use a MySQL RDS instance with Multi-AZ deployments configuration. Use Route 53 and create an A record to point to the ELB.

Answer: A

Question 4

A company has deployed an application on AWS Elastic Beanstalk. The application uses Amazon Aurora for

the database layer. An Amazon CloudFront distribution serves web requests and includes the Elastic Beanstalk

domain name as the origin server. The distribution is configured with an alternate domain name that visitors

use when they access the application.

Each week, the company takes the application out of service for routine maintenance. During the time that the

application is unavailable, the company wants visitors to receive an informational message instead of a

CloudFront error message.

A solutions architect creates an Amazon S3 bucket as the first step in the process.

Which combination of steps should the solutions architect take next to meet the requirements? (Choose three.)

A : Upload static informational content to the S3 bucket.

B : Create a new CloudFront distribution. Set the S3 bucket as the origin.

C : Set the S3 bucket as a second origin in the original CloudFront distribution. Configure the distributionand the S3 bucket to use an origin access identity (OAI).

D : During the weekly maintenance, edit the default cache behavior to use the S3 origin. Revert the changewhen the maintenance is complete.

E : During the weekly maintenance, create a cache behavior for the S3 origin on the new distribution. Setthe path pattern to \ Set the precedence to 0. Delete the cache behavior when the maintenance iscomplete.

F : During the weekly maintenance, configure Elastic Beanstalk to serve traffic from the S3 bucket.

Answer: A,C,D

Question 5

A company needs to optimize the cost of backups for Amazon Elastic File System (Amazon EFS). A solutions architect has already configured a backup plan in AWS Backup for the EFS backups. The backup plan contains a rule with a lifecycle configuration to transition EFS backups to cold storage after 7 days and to keep the backups for an additional 90 days.

After I month, the company reviews its EFS storage costs and notices an increase in the EFS backup costs. The EFS backup cold storage produces almost double the cost of the EFS warm backup storage.

What should the solutions architect do to optimize the cost?

A : dify the backup rule's lifecycle configuration to move the EFS backups to cold storage after 1 day. Set the backup retention period to 30 days.

B : dify the backup rule's lifecycle configuration to move the EFS backups to cold storage after 8 days. Set the backup retention period to 30 days.

C : dify the backup rule's lifecycle configuration to move the EFS backups to cold storage after 1 day. Set the backup retention period to 90 days.

D : dify the backup rule's lifecycle configuration to move the EFS backups to cold storage after 8 days. Set the backup retention period to 98 days.

Answer: A
