Question 37

A solutions architect is designing a new hybrid architecture to extend a company s on-premises infrastructure to AWS The company requires a highly available connection with consistent low latency to an AWS Region. The company needs to minimize costs and is willing to accept slower traffic if the primary connection fails.
What should the solutions architect do to meet these requirements?

A. Provision an AWS Direct Connect connection to a Region Provision a VPN connection as a backup if the primary Direct Connect connection fails.

B. Provision a VPN tunnel connection to a Region for private connectivit

C. Provision a second VPN tunnel for private connectivity and as a backup if the primary VPN connection fails.

D. Provision an AWS Direct Connect connection to a Region Provision a second Direct Connect connection to the same Region as a backup if the primary Direct Connect connection fails.

E. Provision an AWS Direct Connect connection to a Region Use the Direct Connect failover attribute from the AWS CLI to automatically create a backup connection if the primary Direct Connect connection fails.

Correct Answer:A

Question 38

A company runs an online marketplace web application on AWS. The application serves hundreds of thousands of users during peak hours. The company needs a scalable, near-real-time solution to share the details of millions of financial transactions with several other internal applications Transactions also need to be processed to remove sensitive data before being stored in a document database for low-latency retrieval.
What should a solutions architect recommend to meet these requirements?

A. Store the transactions data into Amazon DynamoDB Set up a rule in DynamoDB to remove sensitive data from every transaction upon write Use DynamoDB Streams to share the transactions data with other applications

B. Stream the transactions data into Amazon Kinesis Data Firehose to store data in Amazon DynamoDB and Amazon S3 Use AWS Lambda integration with Kinesis Data Firehose to remove sensitive dat

C. Other applications can consumethe data stored in Amazon S3

D. Stream the transactions data into Amazon Kinesis Data Streams Use AWS Lambda integration to remove sensitive data from every transaction and then store the transactions data in Amazon DynamoDB Other applications can consumethe transactions data off the Kinesis data stream.

E. Store the batched transactions data in Amazon S3 as file

F. Use AWS Lambda to process every file and remove sensitive data before updating the files in Amazon S3 The Lambda function then stores the data in Amazon DynamoDBOther applications can consume transaction files stored in Amazon S3.

Correct Answer:C
Explanation
The destination of your Kinesis Data Firehose delivery stream. Kinesis Data Firehose can send data records to various destinations, including Amazon Simple Storage Service (Amazon S3), Amazon Redshift, Amazon OpenSearch Service,
and any HTTP endpoint that is owned by you or any of your third-party service providers. The following are the supported destinations:
* Amazon OpenSearch Service
* Amazon S3
* Datadog
* Dynatrace
* Honeycomb
* HTTP Endpoint
* Logic Monitor
* MongoDB Cloud
* New Relic
* Splunk

E. Use a partition placement grou

F. Create shared tile systems across the instances by using Amazon Elastic File System (Amazon EFS).

G. Use a spread placement grou

H. Attach a single Provisioned IOPS SSD Amazon Elastic Block Store (Amazon EBS) volume to all the instances by using Amazon EBS Multi-Attach

Question 40

A company uses an Amazon Auroia PostgreSQL DB cluster 10 store its critical data m tne us-east-l Region The company wants to develop a disaster recovery plan to recover the database m the us west 1 Region The company has a recovery time objective (RTO) of S minutes and has a recovery point objective (RPO) of 1 minute
What should a solutions architect do to moot these requirements?

A. Create a read replica in us-west-1 Set the DB cluster to automaKaliy fail over to the read replica if the primary instance is not responding

B. Create an Aurora global database Sel us-west-1 as the secondary Region update connections to use the writer and reader endpomis as appropriate

C. Set up a second Aurora DB cluster in us-west-1 Use logical replication to keep the databases synchronized Create an Amazon EvontBridgc (Amazon CloudWatch Events) rule to change thedatabase endpoint rf the primary DB cluster does not respond.

D. Use Aurora automated snapshots to store data in an Amazon S3 bucket Enable S3 Verswnm

E. Configure S3 Cross-Region Replication to us-west-1 Create a second Aurora DB cluster in us-west-1 Create an Amazon EventBndge (Amazon CloudWatch Events) rule to restore the snapshot il the primary D8 cluster does not respond

Correct Answer:B

Question 41

A gaming company is moving its public scoreboard from a data center to the AWS Cloud. The company uses Amazon EC2 Windows Server instances behind an Application Load Balancer to host its dynamic application. The company needs a highly available storage solution for the application.

Which combination of steps should a solutions architect take to meet these requirements? (Select TWO.)

A. Store the static files on Amazon S3. Use Amazon

B. CloudFront to cache objects at the edge.

C. Store the static files on Amazon S3. Use Amazon ElastiCache to cache objects at the edge.

D. Store the server-side code on Amazon Elastic File System (Amazon EFS). Mount the EFS volume on each EC2 instance to share the files.

E. Store the server-side code on Amazon FSx for Windows File Serve

F. Mount the FSx for Windows File Server volume on each EC2 instance to share the files.

G. Store the server-side code on a General Purpose SSD (gp2) Amazon Elastic Block Store (Amazon EBS) volum

H. Mount the EBS volume on each EC2 instance to share the files.

Correct Answer:AE

Question 42

A company hosts a two-tier application on Amazon EC2 instances and Amazon RDS. The application's demand varies based on the time of day. The load is minimal after work hours and on weekends. The EC2 instances run in an EC2 Auto Scaling group that is configured with a minimum of two instances and a maximum of five instances. The application must be available at all times, but the company is concerned about overall cost.
