You need a persistent and durable storage to trace call activity of an IVR (Interactive Voice Response) system.Call duration is mostly in the 2-3 minutes timeframe.Each traced call can be either active or terminated.An external application needs to know each minute the list of currently active calls.Usually there are a few calls/second, but once per month there is a periodic peak up to 1000 calls/second for a few hours.The system is open 24/7 and any downtime should be avoided.Historical data is periodically archived to files.Cost saving is a priority for this project.What database implementation would better fit this scenario, keeping costs as low as possible?Read More →

A 3-tier e-commerce web application is current deployed on-premises and will be migrated to AWS for greater scalability and elasticity.The web server currently shares read-only data using a network distributed file system.The app server tier uses a clustering mechanism for discovery and shared session state that depends on IP multicast.The database tier uses shared-storage clustering to provide database fall over capability, and uses several read slaves for scaling.Data on all servers and the distributed file system directory is backed up weekly to off-site tapes.Which AWS storage and database architecture meets the requirements of the application?Read More →

A digital marketing company has multiple AWS accounts that belong to various teams.The creative team uses an Amazon S3 bucket in its AWS account to securely store images and media files that are used as content for the company’s marketing campaigns.The creative team wants to share the S3 bucket with the strategy team so that the strategy team can view the objects.A solutions architect has created an IAM role that is named strategy_reviewer in the Strategy account.The solutions architect also has set up a custom AWS Key Management Service (AWS KMS) key in the Creative account and has associated the key with the S3 bucket.However, when users from the Strategy account assume the IAM role and try to access objects in the S3 bucket, they receive an Access Denied error.The solutions architect must ensure that users in the Strategy account can access the S3 bucket.The solution must provide these users with only the minimum permissions that they need.Which combination of steps should the solutions architect take to meet these requirements? (Choose three.)Read More →

You have an application running on an EC2 instance which will allow users to download files from a private S3 bucket using a pre-signed URL. Before generating the URL, the application should verify the existence of the file in S3.How should the application use AWS credentials to access the S3 bucket securely?Read More →
