A company's application depends on a third-party API to retrieve data. The third-party API has been experiencing intermittent outages, causing the application to fail. The company wants to improve the application's resilience to these outages. What should a solutions architect do?

Implement a circuit breaker pattern in the application to fail fast and provide a fallback response.

Use Amazon CloudFront to cache the API responses and serve them from the edge.

Move the application to a different AWS Region to be closer to the third-party API.

Increase the timeout for the API calls to allow more time for the third-party service to respond.

A company runs a critical application that uses an Amazon RDS for PostgreSQL database. The company has a Recovery Time Objective (RTO) of 1 hour and a Recovery Point Objective (RPO) of 15 minutes. The database is currently a single instance in a single Availability Zone. The company wants to improve the disaster recovery posture without changing the application. What should a solutions architect do?

Enable Multi-AZ deployment and create a cross-region read replica.

Create a manual snapshot every 15 minutes and store it in Amazon S3.

Enable automated backups and increase the backup retention period to 35 days.

Move the database to an EC2 instance and use a RAID 1 mirror for redundancy.

What is the primary purpose of chaos engineering?

To proactively identify weaknesses in a system by intentionally injecting failures

To improve the security of a system by simulating attacks

To automate the deployment of new features

To reduce the cost of running a system by eliminating unnecessary components

What is the primary purpose of an incident response runbook?

To provide step-by-step instructions for diagnosing and resolving common incidents

To record all incidents for compliance purposes

To replace the need for monitoring and alerting

To automate all incident responses without human intervention

What is the primary purpose of cross-region replication for Amazon S3 buckets?

To protect against region-wide disasters by maintaining a copy in another region

To reduce storage costs by storing data in cheaper regions

To comply with data residency requirements by keeping data in specific regions

To improve read performance for users in different regions
