SAP-C02 exam dumps: questions 101 to 200 of 677

Correct answers: A, D

• A. Correct.

  Correct: AWS Glue provides automated schema detection and supports Extract, Transform, and Load (ETL) workflows. The Amazon Redshift COPY command efficiently loads bulk data into Redshift.

• B. Incorrect.

  Incorrect: While Amazon EMR is a powerful tool for big data processing, it is not the most efficient or cost-effective solution for schema detection and data transformation in this scenario. It also requires more operational overhead compared to AWS Glue.

• C. Incorrect.

  Incorrect: AWS Data Pipeline can handle ETL, but it requires custom scripting and significant management effort, which increases operational overhead.

• D. Correct.

  Correct: AWS Glue Data Catalog centralizes metadata management for Redshift and other data sources, and Glue jobs can automate the ETL processes, minimizing operational overhead.

• E. Incorrect.

  Incorrect: Amazon Kinesis Data Firehose is designed for near-real-time streaming, which is not a requirement in this case. It also does not support advanced schema detection or transformation.

Correct answers: A, B, C, D

• A. Correct.

  Using Amazon CloudFront can help cache static content at edge locations globally, which reduces latency for users accessing static assets. Configuring the ALB as the origin ensures dynamic content is still handled correctly.

• B. Correct.

  AWS Global Accelerator provides static IP addresses and utilizes the AWS global network for routing traffic, improving performance and reducing latency for global users.

• C. Correct.

  Deploying additional Auto Scaling groups in different regions and using latency-based routing in Route 53 allows traffic to be routed to the region with the lowest latency for each user.

• D. Correct.

  Amazon Aurora Global Database replicates data across multiple regions with low latency, which ensures the database tier is performant and resilient for global access.

• E. Incorrect.

  Replacing the ALB with a Network Load Balancer is not relevant in this case, as the ALB is designed for HTTP/HTTPS traffic and provides features like host-based and path-based routing, which are critical for this web application.

Correct answers: B, D

• A. Incorrect.

  Amazon API Gateway is suitable for request routing, but Amazon SQS is better for decoupling and asynchronous communication, not low-latency inter-service communication typically required for microservices.

• B. Correct.

  Amazon API Gateway is well-suited for request routing, and Amazon EventBridge is a fully managed event bus service that supports asynchronous inter-service communication, making it a suitable choice for microservices architectures.

• C. Incorrect.

  AWS App Mesh is a service mesh solution for service discovery and communication but does not directly address the need for request routing or fully managed, serverless inter-service communication.

• D. Correct.

  Amazon API Gateway provides request routing, and AWS Lambda can execute service logic in a serverless and scalable manner, meeting the requirements for microservices.

• E. Incorrect.

  Amazon API Gateway can handle request routing, but Amazon SNS is primarily used for pub/sub messaging patterns and not optimized for low-latency, direct inter-service communication.

Correct answers: A, C

• A. Correct.

  This option is correct. Using Amazon RDS Read Replicas allows the application to offload read queries to the replicas, reducing the load on the primary database and improving performance during traffic spikes.

• B. Incorrect.

  While scaling the RDS instance vertically can improve performance, it may not be the most cost-effective or scalable solution for handling spikes during seasonal events. Additionally, it could lead to downtime during the scaling process.

• C. Correct.

  This option is correct. Amazon ElastiCache for Redis can cache frequently accessed query results, reducing the number of database queries and improving overall application performance during high-traffic events.

• D. Incorrect.

  Migrating to DynamoDB would require significant changes to the application architecture and is not necessary for addressing temporary spikes in traffic.

• E. Incorrect.

  Multi-AZ deployment is designed for high availability and failover rather than improving read performance. It does not address the query latency issue directly.

Correct answer: A

• A. Correct.

  This is the correct answer. AWS Control Tower is purpose-built to set up a landing zone with governance guardrails, which allows for central management of policies while still enabling account-level customizations within the guardrails.

• B. Incorrect.

  While SCPs in AWS Organizations can enforce policies, they do not provide the comprehensive governance framework, automation, and account setup capabilities that AWS Control Tower offers.

• C. Incorrect.

  AWS Config is useful for monitoring compliance and detecting configuration changes but does not provide the governance or policy enforcement capabilities of AWS Control Tower.

• D. Incorrect.

  AWS Security Hub is designed for aggregating security findings and improving visibility but does not enforce policies or manage account governance like AWS Control Tower.
