1. A healthcare company stores highly sensitive patient records. Compliance requires that multiple copies be stored in different locations. Each record must be stored for 7 years. The company has a service level agreement (SLA) to provide records to government agencies immediately for the first 30 days and then within 4 hours of a request thereafter. What should a solutions architect recommend?

A) Use Amazon S3 with cross-origin resource sharing (CORS) enabled. After 30 days, transition the data to Amazon S3 Glacier Deep Archive using a lifecycle policy
B) Use Amazon S3 with cross-origin resource sharing (CORS) enabled. After 30 days, transition the data to Amazon S3 Glacier using a lifecycle policy
C) Use Amazon S3 with cross-Region replication enabled. After 30 days, transition the data to Amazon S3 Glacier using a lifecycle policy
D) Use Amazon S3 with cross-Region replication enabled. After 30 days, transition the data to Amazon S3 Glacier Deep Archive using a lifecycle policy



2. A company has a mobile chat application with a data store based in Amazon DynamoDB. Users would like new messages to be read with as little latency as possible. A solutions architect needs to design an optimal solution that requires minimal application changes.Which method should the solutions architect select?

A) Double the number of read capacity units for the new messages table in DynamoDB. Continue to use the existing DynamoDB endpoint.
B) Add an Amazon ElastiCache for Redis cache to the application stack. Update the application to point to the Redis cache endpoint instead of DynamoDB
C) Add DynamoDB read replicas to handle the increased read load. Update the application to point to the read endpoint for the read replicas.
D) Configure Amazon DynamoDB Accelerator (DAX) for the new messages table. Update the code to use the DAX endpoint



3. A company has a website running on Amazon EC2 instances across two Availability Zones. The company is expecting spikes in traffic on specific holidays, and wants to provide a consistent user experience.How can a solutions architect meet this requirements?

A) Use simple scaling
B) Use lifecycle hooks
C) Use step scaling
D) Use scheduled scaling



4. A company is using a VPC peering strategy to connect its VPCs in a single Region to allow for cross-communication. A recent increase in account creations and VPCs has made it difficult to maintain the VPC peering strategy, and the company expects to grow to hundreds of VPCs. There are also new requests to create site-to-site VPNs with some of the VPCs. A solutions architect has been tasked with creating a centrally managed networking setup for multiple accounts, VPCs and VPNs.Which networking solution meets these requirements?

A) Configure a hub-and-spoke VPC and route all traffic through VPC peering
B) Configure shared VPCs and VPNs and share to each other.
C) Configure a transit gateway with AWS Transit Gateway and connect all VPCs and VPNs
D) Configure an AWS Direct Connect connection between all VPCs and VPNs



5. A company operates a website on Amazon EC2 Linux instances. Some of the instances are failing. Troubleshooting points to insufficient space on the failed instances. The operations team lead needs a solution to monitor this.What should solutions architect recommend?

A) Use EC2 metadata to collect information, then publish it to Amazon CloudWatch custom metrics. Monitor Swap Usage metrics in CloudWatch.
B) Enable detailed monitoring in the EC2 console. Create an Amazon CloudWatch Swap Utilization custom metric. Monitor SwapUtilization metrics in CloudWatch.
C) Configure an Amazon CloudWatch Swap Usage metric dimension. Monitor the Swap Usage dimension in the EC2 metrics in CloudWatch.
D) Install an Amazon CloudWatch agent on the instances. Run an appropriate script on a set schedule. Monitor Swap Utilization metrics in CloudWatch.
