A company runs a database on Amazon Aurora in the us-east-1 Region. The company has a disaster recovery requirement that the database be available in another Region. Which solution meets this requirement with minimal disruption to the database operations?
Correct Answer: B
The solution that meets the requirement of the company that runs a database on Amazon Aurora in the us-east-1 Region and has a disaster recovery requirement that the database be available in another Region with minimal disruption to the database operations is to deploy Aurora cross-Region read replicas. Aurora cross-Region read replicas are secondary Aurora clusters that are created in a different AWS Region from the primary Aurora cluster, and are kept in sync with the primary cluster using physical replication. The company can use Aurora cross-Region read replicas to improve the availability and durability of the database, as well as to reduce the recovery time objective (RTO) and recovery point objective (RPO) in case of a regional disaster. Performing an Aurora Multi-AZ deployment, creating Amazon EBS volume snapshots for Aurora and copying them to another Region, and deploying Aurora Replicas are not the best solutions for this requirement. An Aurora Multi-AZ deployment is a configuration that creates one or more Aurora Replicas within the same AWS Region as the primary Aurora cluster, and provides automatic failover in case of an Availability Zone outage. However, this does not provide cross-Region disaster recovery. Creating Amazon EBS volume snapshots for Aurora and copying them to another Region is a manual process that requires stopping the database, creating the snapshots, copying them to the target Region, and restoring them to a new Aurora cluster. This process can cause significant downtime and data loss. Deploying Aurora Replicas is a configuration that creates one or more secondary Aurora clusters within the same AWS Region as the primary Aurora cluster, and provides read scaling and high availability. However, this does not provide cross-Region disaster recovery.
Question 412
Which AWS service helps developers use loose coupling and reliable messaging between microservices?
Correct Answer: D
Amazon Simple Queue Service (Amazon SQS) is a service that provides fully managed message queues for asynchronous communication between microservices. It helps developers use loose coupling and reliable messaging by allowing them to send, store, and receive messages between distributed components without losing them or requiring each component to be always available1. Elastic Load Balancing is a service that distributes incoming traffic across multiple targets, such as Amazon EC2 instances, containers, and IP addresses. Amazon Simple Notification Service (Amazon SNS) is a service that provides fully managed pub/sub messaging for event-driven and push-based communication between microservices. Amazon CloudFront is a service that provides a fast and secure content delivery network (CDN) for web applications.
Question 413
Which AWS Support plan provides the full set to AWS Trusted Advisor checks at the LOWEST cost?
Correct Answer: B
AWS Trusted Advisor is a tool that helps customers optimize their AWS environment by providing real-time guidance in five key areas: cost optimization, performance, security, fault tolerance, and service limits. However, the availability of the full set of Trusted Advisor checks depends on the AWS Support plan chosen. * AWS Developer Support: This plan provides access to only seven core Trusted Advisor checks. It is designed for developers experimenting or testing in AWS and does not offer the full set of Trusted Advisor checks. * AWS Business Support: This plan is the lowest-cost support plan that provides access to the full set of AWS Trusted Advisor checks. Business Support is intended for production workloads, providing a broader range of checks, 24x7 access to Cloud Support Engineers, and more extensive support features. * AWS Enterprise On-Ramp Support: This plan offers access to all Trusted Advisor checks as well but is more expensive than the Business Support plan. It is designed for customers running production workloads and needing additional technical support but does not require the full level of engagement that comes with Enterprise Support. * AWS Enterprise Support: This is the most comprehensive and highest-cost support plan, providing access to all Trusted Advisor checks and a full range of AWS Support resources, including a Technical Account Manager (TAM), account management, concierge support, and more. Conclusion:The correct answer is B. AWS Business Support, as it provides access to the full set of AWS Trusted Advisor checks at the lowest cost. AWS Developer Support does not offer the complete checks, and both AWS Enterprise On-Ramp and AWS Enterprise Support are higher-cost plans that also provide the full checks.
