Question 71

- (Exam Topic 2)
A company wants to migrate its data analytics environment from on premises to AWS The environment consists of two simple Node js applications One of the applications collects sensor data and loads it into a MySQL database The other application aggregates the data into reports When the aggregation jobs run. some of the load jobs fail to run correctly
The company must resolve the data loading issue The company also needs the migration to occur without interruptions or changes for the company's customers
What should a solutions architect do to meet these requirements'?

A. Set up an Amazon Aurora MySQL database as a replication target for the on-premises database Create an Aurora Replica for the Aurora MySQL database, and move the aggregation jobs to run against the Aurora Replica Set up collection endpomts as AWS Lambda functions behind a Network Load Balancer (NLB). and use Amazon RDS Proxy to wnte to the Aurora MySQL database When the databases are synced disable the replication job and restart the Aurora Replica as the primary instanc
B. Point the collector DNS record to the NLB.
C. Set up an Amazon Aurora MySQL database Use AWS Database Migration Service (AWS DMS) to perform continuous data replication from the on-premises database to Aurora Move the aggregation jobs to run against the Aurora MySQL database Set up collection endpomts behind an Application Load Balancer (ALB) as Amazon EC2 instances in an Auto Scaling group When the databases are synced, point the collector DNS record to the ALB Disable the AWS DMS sync task after the cutover from on premises to AWS
D. Set up an Amazon Aurora MySQL database Use AWS Database Migration Service (AWS DMS) to perform continuous data replication from the on-premises database to Aurora Create an Aurora Replica for the Aurora MySQL database and move the aggregation jobs to run against the Aurora Replica Set up collection endpoints as AWS Lambda functions behind an Application Load Balancer (ALB) and use Amazon RDS Proxy to write to the Aurora MySQL database When the databases are synced, point the collector DNS record to the ALB Disable the AWS DMS sync task after the cutover from on premises to AWS
E. Set up an Amazon Aurora MySQL database Create an Aurora Replica for the Aurora MySQL database and move the aggregation jobs to run against the Aurora Replica Set up collection endpoints as an Amazon Kinesis data stream Use Amazon Kinesis Data Firehose to replicate the data to the Aurora MySQL database When the databases are synced disable the replication job and restart the Aurora Replica as the primary instance Point the collector DNS record to the Kinesis data stream.

Correct Answer:C

Question 72

- (Exam Topic 2)
A company is migrating an application to the AWS Cloud. The application runs in an on-premises data center and writes thousands of images into a mounted NFS file system each night After the company migrates the application, the company will host the application on an Amazon EC2 instance with a mounted Amazon Elastic File System (Amazon EFS) file system.
The company has established an AWS Direct Connect connection to AWS Before the migration cutover. a solutions architect must build a process that will replicate the newly created on-premises images to the EFS file system
What is the MOST operationally efficient way to replicate the images?

A. Configure a periodic process to run the aws s3 sync command from the on-premises file system to Amazon S3 Configure an AWS Lambda function to process event notifications from Amazon S3 and copy the images from Amazon S3 to the EFS file system
B. Deploy an AWS Storage Gateway file gateway with an NFS mount poin
C. Mount the file gateway file system on the on-premises serve
D. Configure a process to periodically copy the images to the mount point
E. Deploy an AWS DataSync agent to an on-premises server that has access to the NFS file system Send data over the Direct Connect connection to an S3 bucket by using a public VIF Configure an AWS Lambda function to process event notifications from Amazon S3 and copy the images from Amazon S3 to the EFS file system
F. Deploy an AWS DataSync agent to an on-premises server that has access to the NFS file system Send data over the Direct Connect connection to an AWS PrivateLink interface VPC endpoint for Amazon EFS by using a private VIF Configure a DataSync scheduled task to send the images to the EFS file system every 24 hours.

Correct Answer:A

Question 73

- (Exam Topic 2)
A company has an on-premises monitoring solution using a PostgreSQL database for persistence of events. The database is unable to scale due to heavy ingestion and it frequently runs out of storage.
The company wants to create a hybrid solution and has already set up a VPN connection between its network and AWS. The solution should include the following attributes:
• Managed AWS services to minimize operational complexity
• A buffer that automatically scales to match the throughput of data and requires no on-going administration.
• A visualization toot to create dashboards to observe events in near-real time.
• Support for semi -structured JSON data and dynamic schemas.
Which combination of components will enabled© company to create a monitoring solution that will satisfy these requirements'' (Select TWO.)

A. Use Amazon Kinesis Data Firehose to buffer events Create an AWS Lambda function 10 process and transform events
B. Create an Amazon Kinesis data stream to buffer events Create an AWS Lambda function to process and transform evens
C. Configure an Amazon Aurora PostgreSQL DB cluster to receive events Use Amazon Quick Sight to read from the database and create near-real-time visualizations and dashboards
D. Configure Amazon Elasticsearch Service (Amazon ES) to receive events Use the Kibana endpoint deployed with Amazon ES to create near-real-time visualizations and dashboards.
E. Configure an Amazon Neptune 0 DB instance to receive events Use Amazon QuickSight to read from the database and create near-real-time visualizations and dashboards

Correct Answer:DE

Question 74

- (Exam Topic 2)
A large company has a business-critical application that runs in a single AWS Region The application consists of multiple Amazon EC2 instances and an Amazon RDS Multi-AZ DB instance The EC2 instances run In an Amazon EC2 Auto Scaling group across multiple Availability Zones
A solutions architect is implementing a disaster recovery (DR) plan for the application The solutions architect has created a pilot light application deployment in a new Region, which is referred to as the DR Region The DR environment has an Auto Scaling group with a single EC2 instance and a read replica of the RDS DB instance
The solutions architect must automate a failover from the primary application environment to the pilot light environment in the DR Region
Which solution meets these requirements with the MOST operational efficiency''

A. Publish an application availability metric to Amazon CloudWatch in the DR Region from the application environment in the primary Region Create a CloudWatch alarm in the DR Region that is invoked when the application availability metric stops being delivered Configure the CloudWatch alarm to send a notification to an Amazon Simple Notification Service (Amazon SNS> topic in the DR Region Add an email subscription to the SNS topic that sends messages to the application owner upon notification, instruct a systems operator to sign in to the AWS Management Console and initiate failover operations for the application
B. Create a cron task that runs every 5 minutes by using one of the application's EC2 instances in the primary Region Configure the cron task to check whether the application is available Upon failure, the cron task notifies a systems operator and attempts to restart the application services
C. Create a cron task that runs every 5 minutes by using one of the application's EC2 instances in the primary Region Configure the cron task to check whether the application is available Upon failure, the cron task modifies the DR environment by promoting the read replica and by adding EC2 instances to the Auto Scaling group
D. Publish an application availability metric to Amazon CloudWatch in the DR Region from the application environment in the primary Region Create a CloudWatch alarm in the DR Region that is invoked when the application availability metric stops being delivered Configure the CloudWatch alarm to send a notification to an Amazon Simple Notification Service (Amazon SNS) topic in the DR Region Use an AWS Lambda function that is invoked by Amazon SNS in the DR Region to promote the read replica and to add EC2 instances to the Auto Scaling group

Correct Answer:D

Question 75

- (Exam Topic 1)
A company is building a hybrid solution between its existing on-premises systems and a new backend in AWS. The company has a management application to monitor the state of its current IT infrastructure and automate responses to issues. The company wants to incorporate the status of its consumed AWS services into the application. The application uses an HTTPS endpoint to receive updates.
