Question 102

Exam Question

A solutions architect is building a web application that uses an Amazon RDS for PostgreSQL DB instance The DB instance is expected to receive many more reads than writes. The solutions architect needs to ensure that the large amount of read traffic can be accommodated and that the DB instance is highly available.

Which steps should the solutions architect take to meet these requirements? (Select THREE)

A. Create multiple read replicas and put them into an Auto Scaling group.

B. Create multiple read replicas in different Availability Zones.

C. Create an Amazon Route 53 hosted zone and a record set for each read replica with a TTL and a weighted routing policy.

D. Create an Application Load Balancer (ALB) and put the read replicas behind the ALB.

E. Configure an Amazon CloudWatch alarm to detect a failed read replica. Set the alarm to directly invoke an AWS Lambda function to delete its Route 53 record set.

F. Configure an Amazon Route 53 health check for each read replica using its endpoint

Correct Answer

B. Create multiple read replicas in different Availability Zones.

C. Create an Amazon Route 53 hosted zone and a record set for each read replica with a TTL and a weighted routing policy.

F. Configure an Amazon Route 53 health check for each read replica using its endpoint

Explanation

You can use Amazon Route 53 weighted record sets to distribute requests across your read replicas. Within a Route 53 hosted zone, create individual record sets for each DNS endpoint associated with your read replicas and give them the same weight. Then, direct requests to the endpoint of the record set. You can incorporate Route 53 health checks to be sure that Route 53 directs traffic away from unavailable read replicas

B. Associate an AWS WAF web ACL with the CloudFront distribution. Select the managed Amazon IP reputation rule group for the web ACL with a deny action.

Explanation

IP reputation rule groups allow you to block requests based on their source. Choose one or more of these rule groups if you want to reduce your exposure to BOTS!!!! traffic or exploitation attempts The Amazon IP reputation list rule group contains rules that are based on Amazon internal threat intelligence.

This is useful if you would like to block IP addresses typically associated with bots or other threats.

Inspects for a list of IP addresses that have been identified as bots by Amazon threat intelligence.

Question 104

Exam Question

A company is planning on hosting its ecommerce platform on AWS using a multi-tier web application designed for a NoSQL database. The company plans to use the us-west-2 Region as its primary Region. The company want to ensure that copies of the application and data are available in a second Region, us-west-1, for disaster recovery. The company wants to keep the time to fail over as low as possible. Failing back to the primary Region should be possible without administrative interaction after the primary service is restored.

Which design should the solutions architect use?

A. Use AWS Cloud Formation StackSets lo create the stacks in both Regions with Auto Scaling groups for the web and application tiers. Asynchronously replicate static content between Regions using Amazon S3 cross-Region replication. Use an Amazon Route 53 DNS failover routing policy to direct users to the secondary site in us-west-1 in the event of an outage. Use Amazon DynamoDB global tables for the database tier.

B. Use AWS Cloud Formation StackSets to create the stacks in both Regions with Auto Scaling groups for the web and application tiers. Asynchronously replicate static content between Regions using Amazon S3 cross-Region replication. Use an Amazon Route 53 DNS failover routing policy to direct users to the secondary site in us-west-1 in the event of an outage. Deploy an Amazon Aurora global database for the database tier.

C. Use AWS Service Catalog to deploy the web and application servers in both Regions. Asynchronously replicate static content between the two Regions using Amazon S3 cross-Region replication. Use Amazon Route 53 health checks to identify a primary Region failure and update the public DNS entry listing to the secondary Region in the event of an outage. Use Amazon RDS for MySQL with cross-Region replication for the database tier.

D. Use AWS CloudFormation StackSets to create the stacks in both Regions using Auto Scaling groups for the web and application tiers. Asynchronously replicate static content between Regions using Amazon S3 cross-Region replication. Use Amazon CloudFront with static files in Amazon S3, and multi-Region origins for the front-end web tier. Use Amazon DynamoD8 tables in each Region with scheduled backups to Amazon S3.

Correct Answer

A. Use AWS Cloud Formation StackSets lo create the stacks in both Regions with Auto Scaling groups for the web and application tiers. Asynchronously replicate static content between Regions using Amazon S3 cross-Region replication. Use an Amazon Route 53 DNS failover routing policy to direct users to the secondary site in us-west-1 in the event of an outage. Use Amazon DynamoDB global tables for the database tier.

Explanation

In this design, AWS Cloud Formation StackSets is used to create the stacks in both Regions, ensuring consistency across both environments. The Auto Scaling groups for the web and application tiers provide scalability and reliability, while the asynchronous replication of static content using Amazon S3 cross-Region replication ensures data availability. The use of an Amazon Route 53 DNS failover routing policy allows for fast and automatic failover to the secondary Region in the event of an outage, without the need for administrative interaction. The use of Amazon DynamoDB global tables for the database tier ensures that data is always available, even in the event of an outage.

Question 105

Exam Question

A software-as-a-service (SaaS) provider exposes APIs through an Application Load Balancer (ALB). The ALB connects to an Amazon Elastic Kubernetes Service (Amazon EKS) cluster that is deployed in the us-east-I Region. The exposed APIs contain usage of a few non-standard REST methods: LINK, UNLINK, LOCK, and UNLOCK.

Users outside the United States are reporting long and inconsistent response times for these APIs. A solutions architect needs to resolve this problem with a solution that minimizes operational overhead.

Which solution meets these requirements?

A. Add an Amazon CloudFront distribution. Configure the ALB as the origin.

B. Add an Amazon API Gateway edge-optimized API endpoint to expose the APIs. Configure the ALB as the target.
