A Solutions Architect wants to design a solution to save costs for EC2 instances that do not need to run during a 2-week company shutdown. The applications running on the instances store data in instance memory (RAM) that must be present when the instances resume operation. Which approach should the solutions architect recommend to shut down and resume the instances?

1 point

A) Modify the application to store the data on instance store volumes. Reattach the volumes while restarting them

B) Snapshot the instances before stopping them. Restore the snapshot after restarting the instances.

C) Run the applications on instances enabled for hibernation. Hibernate the instances before the shutdown.

D) Note the Availability Zone for each instance before stopping it. Restart the instances in the same Availability Zones after the shutdown.

An analytics company is planning to offer a site analytics service to its users. The service will require that the users’ webpages include a JavaScript script that makes authenticated GET requests to the company’s Amazon S3 bucket. What must a solutions architect do to ensure that the script will successfully execute?

1 point

A) Enable cross-origin resource sharing (CORS) on the S3 bucket.

B) Enable S3 versioning on the S3 bucket.

C) Provide the users with a signed URL for the script.

D) Configure a bucket policy to allow public execute privileges.

A company needs to maintain access logs for a minimum of 5 years due to regulatory requirements. The data is rarely accessed once stored, but must be accessible with one day’s notice if it is needed. What is the MOST cost-effective data storage solution that meets these requirements?

1 point

A) Store the data in Amazon S3 Glacier Deep Archive storage and delete the objects after 5 years using a lifecycle rule.

B) Store the data in Amazon S3 Standard storage and transition to Amazon S3 Glacier after 30 days using a lifecycle rule.

C) Store the data in logs using Amazon CloudWatch Logs and set the retention period to 5 years.

D) Store the data in Amazon S3 Standard-Infrequent Access (S3 Standard-IA) storage and delete the objects after 5 years using a lifecycle rule.

A company uses Reserved Instances to run its data-processing workload. The nightly job typically takes 7 hours to run and must finish within a 10-hour time window. The company anticipates temporary increases in demand at the end of each month that will cause the job to run over the time limit with the capacity of the current resources. Once started, the processing job cannot be interrupted before completion. The company wants to implement a solution that would allow it to provide increased capacity as cost-effectively as possible. What should a solutions architect do to accomplish this?

1 point

A) Deploy On-Demand Instances during periods of high demand.

B) Create a second Amazon EC2 reservation for additional instances.

C) Deploy Spot Instances during periods of high demand.

D) Increase the instance size of the instances in the Amazon EC2 reservation to support the increased workload.

You have a group of web designers who frequently upload large zip files of images to S3, often in excess of 5 GB. Recently, team members have reported that they are receiving the error “Your proposed upload exceeds the maximum allowed object size.” What action should you take to resolve the upload problems?

B. Ensure that your web designers are using applications or clients that take advantage of the Multipart Upload API for all uploaded objects.

C. Contact AWS and submit a ticket to have your default S3 bucket size raised; ensure that this is also applied to the target bucket for your web designers’ uploads.

D. Log in to the AWS console, select the S3 service, and locate your bucket. Edit the bucket properties and increase the maximum object size to 50 GB.
