1. A solutions architect at an ecommerce company wants to back up application log data to Amazon S3. The solutions architect is unsure how frequently the logs will be accessed or which logs will be accessed the most. The company wants to keep costs as low as possible by using the appropriate S3 storage class.Which S3 storage class should be implemented to meet these requirements?

A) S3 One Zone-Infrequent Access (S3 One Zone-IA)
B) S3 Glacier
C) S3 Intelligent-Tiering
D) S3 Standard-Infrequent Access (S3 Standard-IA)



2. Organizers for a global event want to put daily reports online as static HTML pages. The pages are expected to generate millions of views from users around the world. The files are stored in an Amazon S3 bucket. A solutions architect has been asked to design an efficient and effective solution.Which action should the solutions architect take to accomplish this?

A) Use Amazon CloudFront with the S3 bucket as its origin.
B) Use cross-Region replication to all Regions.
C) Generate presigned URLs for the files.
D) Use the geoproximity feature of Amazon Route 53.



3. A company is planning to migrate a business-critical dataset to Amazon S3. The current solution design uses a single S3 bucket in the us-east-1 Region with versioning enabled to store the dataset. The company's disaster recovery policy states that all data multiple AWS Regions.How should a solutions architect design the S3 solution?

A) Create an additional S3 bucket in another Region and configure cross-origin resource sharing (CORS).
B) Create an additional S3 bucket with versioning in another Region and configure cross-Region replication.
C) Create an additional S3 bucket in another Region and configure cross-Region replication.
D) Create an additional S3 bucket with versioning in another Region and configure cross-origin resource (CORS).



4. A solutions architect is designing a solution where users will be directed to a backup static error page if the primary website is unavailable. The primary website's DNS records are hosted in Amazon Route 53 where their domain is pointing to an Application Load Balancer (ALB).Which configuration should the solutions architect use to meet the company's needs while minimizing changes and infrastructure overhead?

A) Point a Route 53 alias record to an Amazon CloudFront distribution with the ALB as one of its origins. Then, create custom error pages for the distribution.
B) Set up a Route 53 active-active configuration with the ALB and an Amazon EC2 instance hosting a static error page as endpoints. Route 53 will only send requests to the instance if the heal checks fail for the ALB.
C) Set up a Route 53 active-passive failover configuration. Direct traffic to a static error page hosted within an Amazon S3 bucket when Route 53 health checks determine that the ALB endpoint is unhealthy.
D) Update the Route 53 record to use a latency-based routing policy. Add the backup static error page hosted within an Amazon S3 bucket to the record so the traffic is sent to the most responsive endpoints.



5. A Solutions Architect needs to build a resilient data warehouse using Amazon Redshift. The Architect needs to rebuild the Redshift cluster in another region.Which approach can the Architect take to address this requirement?

A) Modify the Redshift cluster to use AWS Snowball in export mode with data delivered to the other region.
B) Modify the Redshift cluster and configure cross-region snapshots to the other region.
C) Modify the Redshift cluster to take snapshots of the Amazon EBS volumes each day, sharing those snapshots with the other region.
D) Modify the Redshift cluster and configure the backup and specify the Amazon S3 bucket in the other region.
