Exam AWS Certified Solutions Architect - Professional SAP-C02 topic 1 question 396 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Professional SAP-C02
Question #: 396
Topic #: 1
[All AWS Certified Solutions Architect - Professional SAP-C02 Questions]

A company owns a chain of travel agencies and is running an application in the AWS Cloud. Company employees use the application to search for information about travel destinations. Destination content is updated four times each year.

Two fixed Amazon EC2 instances serve the application. The company uses an Amazon Route 53 public hosted zone with a multivalue record of travel.example.com that returns the Elastic IP addresses for the EC2 instances. The application uses Amazon DynamoDB as its primary data store. The company uses a self-hosted Redis instance as a caching solution.

During content updates, the load on the EC2 instances and the caching solution increases drastically. This increased load has led to downtime on several occasions. A solutions architect must update the application so that the application is highly available and can handle the load that is generated by the content updates.

Which solution will meet these requirements?

  • A. Set up DynamoDB Accelerator (DAX) as in-memory cache. Update the application to use DAX. Create an Auto Scaling group for the EC2 instances. Create an Application Load Balancer (ALB). Set the Auto Scaling group as a target for the ALB. Update the Route 53 record to use a simple routing policy that targets the ALB's DNS alias. Configure scheduled scaling for the EC2 instances before the content updates.
  • B. Set up Amazon ElastiCache for Redis. Update the application to use ElastiCache. Create an Auto Scaling group for the EC2 instances. Create an Amazon CloudFront distribution, and set the Auto Scaling group as an origin for the distribution. Update the Route 53 record to use a simple routing policy that targets the CloudFront distribution’s DNS alias. Manually scale up EC2 instances before the content updates.
  • C. Set up Amazon ElastiCache for Memcached. Update the application to use ElastiCache. Create an Auto Scaling group for the EC2 instances. Create an Application Load Balancer (ALB). Set the Auto Scaling group as a target for the ALB. Update the Route 53 record to use a simple routing policy that targets the ALB's DNS alias. Configure scheduled scaling for the application before the content updates.
  • D. Set up DynamoDB Accelerator (DAX) as in-memory cache. Update the application to use DAX. Create an Auto Scaling group for the EC2 instances. Create an Amazon CloudFront distribution, and set the Auto Scaling group as an origin for the distribution. Update the Route 53 record to use a simple routing policy that targets the CloudFront distribution's DNS alias. Manually scale up EC2 instances before the content updates.

Couldn't agree more. They can just ask us, hey for DynamoDB's cache, should you use DAX or ElasticCache or Memcached? Is CloudFront Distribution designed for fixing sudden traffic spike? Then we can just say: 1. DAX; 2. no. :D

Option A correct... other options B. ElastiCache for Redis: While a good caching solution, DAX is specifically optimized for DynamoDB, making it a better choice in this context. C. ElastiCache for Memcached: Memcached is not as feature-rich as Redis and lacks DAX's DynamoDB integration. D. CloudFront: While useful for content delivery, it's not the primary solution for handling database load and scaling EC2 instances.

A and D are similar however manually scale up instances can be eliminated easily. A is right

Selected Answer: A
A: Correct. Utilizes DAX for DynamoDB caching, Auto Scaling for EC2, and ALB for traffic distribution; aligns with best practices. B Incorrect. CloudFront is not optimal for dynamic content load handling; manual scaling is less efficient than scheduled scaling.

Selected Answer: A
A. Configure o DynamoDB Accelerator (DAX) como cache na memória. Atualize o aplicativo para usar o DAX. Crie um grupo do Auto Scaling para as instâncias do EC2. Crie um balanceador de carga de aplicativo (ALB). Defina o grupo do Auto Scaling como destino para o ALB. Atualize o registro do Route 53 para usar uma política de roteamento simples que tenha como alvo o alias DNS do ALB. Configure o escalonamento programado para as instâncias do EC2 antes das atualizações de conteúdo.
