A SysOps administrator launches an Amazon EC2 Linux instance in a public subnet.When the instance is running, the SysOps administrator obtains the public IP address and attempts to remotely connect to the Instance multiple times.However, the SysOps administrator always receives a timeout error.Which action will allow the SysOps administrator to remotely connect to the instance?Read More →
An online retailer needs to regularly process large product catalogs, which are handled in batches.These are sent out to be processed by people using theAmazon Mechanical Turk service, but the retailer has asked its Solutions Architect to design a workflow orchestration system that allows it to handle multiple concurrent Mechanical Turk operations, deal with the result assessment process, and reprocess failures.Which of the following options gives the retailer the ability to interrogate the state of every workflow with the LEAST amount of implementation effort?Read More →
A company has a requirement that no Amazon EC2 security group can allow SSH access from the CIDR block 0.0.0.0/0.The company wants to monitor compliance with this requirement at all times and wants to receive a near-real-time notification if any security group is noncompliant.A security engineer has configured AWS Config and will use the restricted-ssh managed rule to monitor the security groups.What should the security engineer do next to meet these requirements?Read More →
A company uses an Amazon EC2 instance to run a script to poll for and process messages in an Amazon Simple Queue Service (Amazon SQS) queue.The company wants to reduce operational costs while maintaining its ability to process a growing number of messages that are added to the queue.What should a solutions architect recommend to meet these requirements?Read More →
A company has a web application that securely uploads pictures and videos to an Amazon S3 bucket.The company requires that only authenticated users are allowed to post content.The application generates a presigned URL that is used to upload objects through a browser interface.Most users are reporting slow upload times for objects larger than 100 MB.What can a solutions architect do to improve the performance of these uploads while ensuring only authenticated users are allowed to post content?Read More →
An application uses Amazon Kinesis Data Streams to ingest and process large streams of data records in real time.Amazon EC2 instances consume and process the data from the shards of the Kinesis data stream by using Amazon Kinesis Client Library (KCL).The application handles the failure scenarios and does not require standby workers.The application reports that a specific shard is receiving more data than expected.To adapt to the changes in the rate of data flow, the`hot` shard is resharded.Assuming that the initial number of shards in the Kinesis data stream is 4, and after resharding the number of shards increased to 6, what is the maximum number of EC2 instances that can be deployed to process data from all the shards?Read More →
