AWS Most Popular Services

An application allows a manufacturing site to upload files. Each uploaded 3 GB file is processed to extract metadata, and this process takes a few seconds per file. The frequency at which the uploads happen is unpredictable. For instance, there may be no updates for hours, followed by several files being uploaded concurrently.

Which AWS service will meet the above requirements?

• Amazon S3

• Amazon EBS

• Amazon EFS

• Amazon Storage Gateway VTL

What architecture addresses this workload in the most cost efficient manner?

• Use a Kinesis Data Delivery Stream to store the file. Use Lambda for processing.

• Use an SQS queue to store the file, to be accessed by a fleet of EC2 Instances.

• Store the file in an EBS volume, which can then be accessed by another EC2 Instance for processing.

• Store the file in an S3 bucket. Use Amazon S3 event notification to invoke a Lambda function for file processing.

A company is to run a service on AWS to provide offsite backups for images on laptops and phones.

The solution must support millions of customers with thousands of images per customer. Though the images will be retrieved infrequently, they must be available for retrieval immediately.

Which is the MOST cost efficient storage option that meets these requirements?

• Amazon Glacier with Expedited retrievals

• Amazon S3 Standard Infrequent Access

• Amazon EFS

• Amazon S3 Standard

A Solutions Architect designing a solution to store and archive corporate documents, has determined Amazon Glacier as the right choice of solution.

An important requirement is that the data must be delivered within 10 minutes of a retrieval request.

Which feature in Amazon Glacier can help meet this requirement?

• Vault Lock

• Expedited retrieval

• Standard retrieval

• Bulk retrieval

An application reads and writes objects to an S3 bucket. When the application is fully deployed, the read/write traffic is very high.

How should the architect maximize the Amazon S3 performance?

• Use as many S3 prefixes as you need in parallel to achieve the required throughput.

• Use the STANDARD_IA storage class.

• Prefix each object name with a hex hash key along with the current data.

• Enable versioning on the S3 bucket.

A Solutions Architect is designing a highly scalable system to track records. These records must remain available for immediate download for up to three months and then must be deleted.

What is the most appropriate decision for this use case?

• Store the files in Amazon EBS and create a Lifecycle Policy to remove files after 3 months

• Store the files in Amazon S3 and create a Lifecycle Policy to remove files after 3 months

• Store the files in Amazon Glacier and create a Lifecycle Policy to remove files after 3 months

• Store the files in Amazon EFS and create a Lifecycle Policy to remove files after 3 months

A company needs to store images that are uploaded by users via a mobile application. There is also a need to ensure that a security measure is in place to avoid the data loss.

What step should be taken for protection against unintended user actions?

• Store data in an EBS volume and create snapshots once a week.

• Store data in an S3 bucket and enable versioning.

• Store data in two S3 buckets in different AWS regions.

• Store data on EC2 instance storage.

Development teams in your organization use S3 buckets to store log files for various applications hosted in AWS development environments. The developers intend to keep the logs for a month for troubleshooting purposes, and subsequently purge the logs.

What feature will enable this requirement?

• Adding a bucket policy on the S3 bucket.

• Configuring lifecycle configuration rules on the S3 bucket.

• Creatingan IAM policy for the S3 bucket.

• Enabling CORS on the S3 bucket.

A million images are required to be uploaded to S3. What option ensures optimal performance in this case?

• Usea sequential ID for the prefix.

• Use a hexadecimal hash for the prefix.

• Use a hexadecimal hash for the suffix.

• Use a sequential ID for the suffix.

An application hosted in AWS allows users to upload videos to an S3 bucket. A user is required to be given access to upload some videos for a week based on the profile. How can be this be accomplished in the best way possible?

• Create an IAM bucket policy to provide access for a week’s duration.

• Create a pre-signed URL for each profile which will last for a week’s duration.

• Create an S3 bucket policy to provide access for a week’s duration.

• Create an IAM role to provide access for a week’s duration.
