Question 292

A company is deploying a two-tier web application in a VPC. The web tier is using an Amazon EC2 Auto Scaling group with public subnets that span multiple Availability Zones. The database tier consists of an Amazon RDS for MySQL DB instance in separate private subnets. The web tier requires access to the database to retrieve product information. The web application is not working as intended. The web application reports that it cannot connect to the database. The database is confirmed to be up and running. All configurations for the network ACLs. security groups, and route tables are still in their default states.

What should a solutions architect recommend to fix the application?

A.

Add an explicit rule to the private subnet's network ACL to allow traffic from the web tier's EC2 instances.

B.

Add a route in the VPC route table to allow traffic between the web tier's EC2 instances and Ihe database tier.

C.

Deploy the web tier's EC2 instances and the database tier's RDS instance into two separate VPCs. and configure VPC peering.

D.

Add an inbound rule to the security group of the database tier's RDS instance to allow traffic from the web tier's security group.

Question 293

A company is running a multi-tier recommence web application in the AWS Cloud. The application runs on Amazon EC2 instances with an Amazon RDS for MySQL Multi-AZ OB instance. Amazon ROS is configured with the latest generation DB instance with 2.000 GB of storage In a General Purpose SSD (gp3) Amazon Elastic Block Store (Amazon EBSl volume. The database performance affects the application during periods high demand. A database administrator analyzes the logs in Amazon CloudWatch Logs and discovers that the application performance always degrades when the number of read and write IOPS is higher than 20.000. What should a solutions architect do to improve the application performance?

A.

Replace the volume with a magnetic volume.

B.

Increase the number of IOPS on the gp3 volume.

C.

Replace the volume with a Provisioned IOPS SSD (Io2) volume.

D.

Replace the 2.000 GB gp3 volume with two 1.000 GB gp3 volumes
