SAA-C03 Question 201

Single answer

A company is hosting a web application on an Amazon EC2 instance behind an Application Load Balancer (ALB). During peak traffic, users report slow response times and intermittent errors. You notice that the EC2 instance is operating at 100% CPU utilization. What is the most cost-effective solution to improve application availability and performance?

A
Add more EC2 instances to the target group of the Application Load Balancer.
B
Upgrade the EC2 instance to a larger instance type to handle more traffic.
C
Enable sticky sessions on the Application Load Balancer to route users to the same instance.
D
Configure an Auto Scaling group to dynamically add or remove EC2 instances based on traffic patterns.

Show answer and explanation

Correct answer: D

Explanation

The most cost-effective solution is to configure an Auto Scaling group with the Application Load Balancer. This ensures that additional EC2 instances are launched during peak traffic and terminated during low traffic, optimizing both performance and cost. While adding more EC2 instances or upgrading the instance type might temporarily resolve the issue, these approaches do not dynamically adjust to changes in traffic patterns, which can lead to inefficient resource utilization.

A. Incorrect.
This solution would distribute the traffic across multiple instances, but it does not dynamically adjust the number of instances based on traffic patterns, which may lead to overprovisioning or underprovisioning.
B. Incorrect.
Upgrading the instance may temporarily resolve the issue, but it is not cost-effective in the long term and does not account for variable traffic patterns.
C. Incorrect.
Sticky sessions ensure that users are routed to the same instance, but this does not address the issue of high CPU utilization or scale the application to handle increased traffic.
D. Correct.
Configuring an Auto Scaling group allows the application to automatically scale out during high traffic and scale in during low traffic, improving both cost efficiency and performance.

SAA-C03 Question 202

Single answer

A company is hosting a web application that serves dynamic content to users. The application is deployed across multiple Availability Zones for high availability. The company wants to distribute incoming traffic based on the URL path (e.g., '/images/' should route to one set of instances, and '/api/' should route to another set of instances). Which AWS service configuration is the MOST suitable for this requirement?

A
Use an Application Load Balancer (ALB) with path-based routing rules.
B
Use a Network Load Balancer (NLB) with listener rules for URL paths.
C
Deploy an Auto Scaling group in each Availability Zone and manage traffic distribution using Route 53.
D
Use an Application Load Balancer (ALB) with host-based routing rules.

Show answer and explanation

Correct answer: A

Explanation

The most suitable solution for routing traffic based on URL paths is an Application Load Balancer (ALB) with path-based routing rules. ALB operates at the application layer (Layer 7) and supports advanced routing features like path-based and host-based routing. This makes it ideal for dynamic content routing scenarios like the one described in the question.

A. Correct.
Correct. An Application Load Balancer (ALB) supports path-based routing, making it the ideal choice for routing traffic based on URL paths.
B. Incorrect.
Incorrect. A Network Load Balancer (NLB) operates at the transport layer (Layer 4) and does not support advanced routing features like path-based routing.
C. Incorrect.
Incorrect. While Auto Scaling groups and Route 53 can provide high availability, they do not handle routing traffic based on URL paths.
D. Incorrect.
Incorrect. Host-based routing is used to route traffic based on the domain or subdomain in the request, not URL paths. This does not meet the requirement.

SAA-C03 Question 203

Single answer

Your company runs a high-traffic e-commerce platform using Amazon RDS for MySQL. You have noticed a significant increase in the number of database connections during peak hours, leading to connection limits being exceeded and degraded performance. How can you use Amazon RDS Proxy to address this issue?

A
Amazon RDS Proxy pools and manages database connections, reducing the overhead of opening and closing database connections frequently.
B
Amazon RDS Proxy replicates your database to handle the increased number of connections and distributes the load across replicas.
C
Amazon RDS Proxy automatically scales the underlying database instance to handle the increased number of connections.
D
Amazon RDS Proxy caches query results to reduce the number of queries sent to the database.

Show answer and explanation

Correct answer: A

Explanation

Amazon RDS Proxy is designed to manage and pool database connections, which is particularly useful for applications experiencing high connection churn or exceeding connection limits. By reusing existing connections, it reduces the overhead of establishing new connections and improves database performance during peak traffic periods. It does not replicate databases, scale the underlying database instance, or cache query results.

A. Correct.
This is correct. Amazon RDS Proxy establishes and manages a pool of database connections, which helps applications reuse existing connections rather than creating new ones, reducing the load on the database.
B. Incorrect.
This is incorrect. Amazon RDS Proxy does not replicate databases or distribute load across replicas. It focuses on connection pooling and management.
C. Incorrect.
This is incorrect. Amazon RDS Proxy does not scale the database instance. Scaling the database is a separate action managed by the user or through mechanisms like Amazon Aurora’s auto-scaling.
D. Incorrect.
This is incorrect. Amazon RDS Proxy does not cache query results. Its primary function is connection pooling and improving database connection handling.

SAA-C03 Question 204

Single answer

A company is running a multi-tenant application using Amazon RDS for its database. The application experiences unpredictable spikes in traffic, leading to frequent connection timeouts due to the high number of database connections. The development team wants to improve database connection management without modifying the application code. Which solution is the most appropriate for this scenario?

A
Configure Amazon RDS Proxy to pool and share database connections.
B
Enable Amazon RDS read replicas to offload read traffic and reduce database connections.
C
Increase the instance size of the Amazon RDS database to handle more connections.
D
Enable Multi-AZ deployments on the Amazon RDS instance to improve connection handling.

Show answer and explanation

Correct answer: A

Explanation

Amazon RDS Proxy is the best solution for managing unpredictable spikes in database connections because it pools and shares connections efficiently, reducing the risk of connection exhaustion and improving database performance. It also works seamlessly without requiring changes to the application code. Other options either do not address the core issue of connection pooling or are not cost-effective for this use case.

A. Correct.
Correct. Amazon RDS Proxy is specifically designed to pool and share database connections, allowing the application to handle high traffic spikes efficiently without overloading the database or requiring changes to the application code.
B. Incorrect.
Incorrect. While read replicas can reduce the load on the primary database by offloading read traffic, they do not address the problem of connection management or connection pooling.
C. Incorrect.
Incorrect. Increasing the instance size may temporarily handle more connections, but it does not solve the underlying issue of connection pooling or management. This is not a cost-effective or scalable solution for unpredictable traffic spikes.
D. Incorrect.
Incorrect. Multi-AZ deployments improve database availability and fault tolerance but do not impact connection pooling or management, which is the primary issue here.

SAA-C03 Question 205

Select 3

Your company is running an application that connects to an Amazon RDS database. Recently, the application has experienced connection exhaustion issues during traffic spikes, causing downtime. To address this, you decide to implement Amazon RDS Proxy. Which benefits does Amazon RDS Proxy provide in this scenario?

A
Improves application scalability by pooling and sharing database connections.
B
Encrypts data in transit between the application and the database.
C
Allows for database read replicas to be used automatically for write operations.
D

Show answer and explanation

Correct answers: A, B, D

Explanation

Amazon RDS Proxy is designed to improve the performance and availability of applications that use Amazon RDS. It achieves this by pooling and sharing database connections, encrypting data in transit, and minimizing downtime during failovers. However, it does not automatically scale the database instance or enable write operations on read replicas.

A. Correct.
Correct. Amazon RDS Proxy pools and shares database connections, which helps prevent connection exhaustion and improves application scalability.
B. Correct.
Correct. Amazon RDS Proxy ensures data in transit is encrypted using TLS, enhancing security.
C. Incorrect.
Incorrect. Amazon RDS Proxy does not route write operations to read replicas; read replicas are used for read-only queries and require manual configuration.
D. Correct.
Correct. Amazon RDS Proxy reduces downtime during database failovers by automatically handling connection retries, improving application availability.
E. Incorrect.
Incorrect. Amazon RDS Proxy does not scale the underlying RDS instance. Scaling the instance must be done manually or using other AWS features like Auto Scaling.
