A company uses a 100 GB Amazon RDS for Microsoft SQL Server Single-AZ DB instance in the us-east-1 Region to store customer transactions. The company needs high availability and automate recovery for the DB instance.
The companu must also run reports on the RDS database several times a year. The report process causes transactions to take longer than usual to post to the customer‘ accounts.
Which combination of steps will meet these requirements? (Select TWO.)

1. A. Modify the DB instance from a Single-AZ DB instance to a Multi-AZ deployment.
2. B. Take a snapshot of the current DB instanc
3. C. Restore the snapshot to a new RDS deployment in another Availability Zone.
4. D. Create a read replica of the DB instance in a different Availability Zon
5. E. Point All requests for reports to the read replica.
6. F. Migrate the database to RDS Custom.
7. G. Use RDS Proxy to limit reporting requests to the maintenance window.

Correct Answer: BD

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?

1. A. Add an explicit rule to the private subnet's network ACL to allow traffic from the web tier's EC2 instances.
2. B. Add a route in the VPC route table to allow traffic between the web tier's EC2 instances and Ihe database tier.
3. C. Deploy the web tier's EC2 instances and the database tier's RDS instance into two separate VPC
4. D. and configure VPC peering.
5. E. 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.

Correct Answer: D

A company wants to use the AWS Cloud to make an existing application highly available and resilient. The current version of the application resides in the company's data center. The application recently experienced data loss after a database server crashed because of an unexpected power outage.
The company needs a solution that avoids any single points of failure. The solution must give the application the ability to scale to meet user demand.
Which solution will meet these requirements?

1. A. Deploy the application servers by using Amazon EC2 instances in an Auto Scaling group across multiple Availability Zone
2. B. Use an Amazon RDS DB instance in a Multi-AZ configuration.
3. C. Deploy the application servers by using Amazon EC2 instances in an Auto Scaling group in a single Availability Zon
4. D. Deploy the databaseon an EC2 instanc
5. E. Enable EC2 Auto Recovery.
6. F. Deploy the application servers by using Amazon EC2 instances in an Auto Scaling group across multiple Availability Zone
7. G. Use an Amazon RDS DB instance with a read replica in a single Availability Zon
8. H. Promote the read replica to replace the primary DB instance if the primary DB instance fails.
9. I. Deploy the application servers by using Amazon EC2 instances in an Auto Scaling group across multiple Availability Zones Deploy the primary and secondary database servers on EC2 instances across multiple Availability Zones Use Amazon Elastic Block Store (Amazon EBS) Multi-Attach to create shared storage between the instances.

1. A. Use client-side encryption to encrypt the data that is being uploaded to the S3 buckets.
2. B. Use server-side encryption to encrypt the data that is being uploaded to the S3 buckets.
3. C. Create bucket policies that require the use of server-side encryption with S3 managed encryption keys (SSE-S3) for S3 uploads.
4. D. Enable the security option to encrypt the S3 buckets through the use of a default AWS Key Management Service (AWS KMS) key.

A company is using a SQL database to store movie data that is publicly accessible. The database runs on an Amazon RDS Single-AZ DB instance A script runs queries at random intervals each day to record the number of new movies that have been added to the database. The script must report a final total during business hours The company's development team notices that the database performance is inadequate for development tasks when the script is running. A solutions architect must recommend a solution to resolve this issue. Which solution will meet this requirement with the LEAST operational overhead?

1. A. Modify the DB instance to be a Multi-AZ deployment
2. B. Create a read replica of the database Configure the script to query only the read replica
3. C. Instruct the development team to manually export the entries in the database at the end of each day
4. D. Use Amazon ElastiCache to cache the common queries that the script runs against the database

Correct Answer: B
