Question 1: You have an e-commerce website and you are preparing for Black Friday which is the biggest sale of the year. You expect that your traffic will increase by 100x. Your website already using an SQS Standard Queue, and you're running a fleet of EC2 instances in an Auto Scaling Group to consume SQS messages. What should you do to prepare your SQS Queue?

Contact AWS Support to pre-warm your SQS Standard QueueEnable Auto Scaling in your SQS queueIncrease the capacity of the SQS queueDo nothing, SQS scales automatically

Question 2: You have an SQS Queue where each consumer polls 10 messages at a time and finishes processing them in 1 minute. After a while, you noticed that the same SQS messages are received by different consumers resulting in your messages being processed more than once. What should you do to resolve this issue?

Enable Long PollingAdd DelaySeconds parameter to the messages when being producedIncrease the Visibility TimeoutDecrease the Visibility Timeout

Question 3: Which SQS Queue type allows your messages to be processed exactly once and in order?

SQS Standard QueueSQS Dead Letter QueueSQS Delay QueueSQS FIFO Queue

Question 4: You have 3 different applications that you'd like to send them the same message. All 3 applications are using SQS. What is the best approach would you choose?

Use SQS Replication FeatureUse SNS + SQS Fan Out PatternSend messages individually to 3 SQS queues

Question 5: You have a Kinesis data stream with 6 shards provisioned. This data stream usually receiving 5 MB/s of data and sending out 8 MB/s. Occasionally, your traffic spikes up to 2x and you get a ProvisionedThroughputExceeded exception. What should you do to resolve the issue?

Add more ShardsEnable Kinesis ReplicationUse SQS as a buffer to Kinesis

Question 6: You have a website where you want to analyze clickstream data such as the sequence of clicks a user makes, the amount of time a user spends, and where the navigation begins and how it ends. You decided to use Amazon Kinesis, so you have configured the website to send these clickstream data all the way to a Kinesis data stream. While you checking the data sent to your Kinesis data stream, you found that the users' data is not ordered and the data for one individual user is spread across many shards. How would you fix this problem?

There are too many shards, you should only use 1 shardYou shouldn't use multiple consumers, only one and it should re-order dataFor each record sent to Kinesis add a partition key that represents the identity of the user

Question 7: You are running an application that produces a large amount of real-time data that you want to load into S3 and Redshift. Also, these data need to be transformed before being delivered to their destination. What is the best architecture would you choose?

SQS + AWS LambdaSNS + HTTP EndpointKinesis Data Streams + Kinesis Data Firehose

Question 8: Which of the following is NOT a supported subscriber for AWS SNS?

Amazon Kinesis Data StreamsAmazon SQSHTTP(S) EndpointAWS Lambda

Question 9: Which AWS service helps you when you want to send email notifications to your users?

Amazon SQS with AWS LambdaAmazon SNSAmazon Kinesis

Question 10: You're running many micro-services applications on-premises and they communicate using a message broker that supports MQTT protocol. You're planning to migrate these applications to AWS without re-engineering the applications and modifying the code. Which AWS service allows you to get a managed message broker that supports the MQTT protocol?

Amazon SQSAmazon SNSAmazon KinesisAmazon MQ

Question 11: An e-commerce company is preparing for a big marketing promotion that will bring millions of transactions. Their website is hosted on EC2 instances in an Auto Scaling Group and they are using Amazon Aurora as their database. The Aurora database has a bottleneck and a lot of transactions have been failed in the last promotion they have made as they had a lot of transaction and the Aurora database wasn’t prepared to handle these too many transactions. What do you recommend to handle those transactions and prevent any failed transactions?

Use SQS as a buffer to write to AuroraHost the website in AWS Fargate instead of EC2 instancesMigrate Aurora to RDS for SQL Server

Question 12: A company is using Amazon Kinesis Data Streams to ingest clickstream data and then do some analytical processes on it. There is a campaign in the next few days and the traffic is unpredictable which might grow up to 100x. What Kinesis Data Stream capacity mode do you recommend?

Provisioned ModeOn-demand Mode
