Select the correct statement about Amazon ElastiCache.

An organization has a write-intensive mobile application that uses Amazon API Gateway, AWS Lambda, and Amazon DynamoDB. The application has scaled well, however, costs have increased exponentially because of higher than anticipated Lambda costs. The application’s use is unpredictable, but there has been a steady 20% increase in utilization every month. While monitoring the current Lambda functions, the Solutions Architect notices that the execution-time averages 4.5 minutes. Most of the wait time is the result of a high-latency network call to a 3-TB MySQL database server that is on-premises. A VPN is used to connect to the VPC, so the Lambda functions have been configured with a five-minute timeout. How can the Solutions Architect reduce the cost of the current architecture?

A company currently runs a secure application on Amazon EC2 that takes files from on-premises locations through AWS Direct Connect, processes them, and uploads them to a single Amazon S3 bucket. The application uses HTTPS for encryption in transit to Amazon S3, and S3 server-side encryption to encrypt at rest.

Which of the following changes should the Solutions Architect recommend to make this solution more secure without impeding application’s performance?

A company is building a sensor data collection pipeline in which thousands of sensors write data to an Amazon Simple Queue Service (Amazon SQS) queue every minute. The queue is processed by an AWS Lambda function that extracts a standard set of metrics from the sensor data. The company wants to send the data to Amazon CloudWatch. The solution should allow for viewing individual and aggregate sensor metrics and interactively querying the sensor log data using CloudWatch Logs Insights.

What is the MOST cost-effective solution that meets these requirements?

A Solutions Architect is designing a network solution for a company that has applications running in a data center in Northern Virginia. The applications in the company’s data center require predictable performance to applications running in a virtual private cloud (VPC) located in us-east-1, and a secondary VPC in us-west-2 within the same account. The company data center is collocated in an AWS Direct Connect facility that serves the us-east-1 region. The company has already ordered an AWS Direct Connect connection and a cross-connect has been established.

Which solution will meet the requirements at the LOWEST cost?

An organization is setting a website on the AWS VPC. The organization has blocked a few IPs to avoid a D-DOS attack. How can the organization configure that a request from the above mentioned IPs does not access the application instances?

A solutions architect is designing a solution to connect a company’s on-premises network with all the company’s current and future VPCs on AWS. The company is running VPCs in five different AWS Regions and has at least 15 VPCs in each Region.

The company’s AWS usage is constantly increasing and will continue to grow. Additionally, all the VPCs throughout all five Regions must be able to communicate with each other. The solution must maximize scalability and ease of management.

Which solution meets these requirements?

Which statement is NOT true about accessing remote AWS region in the US by your AWS Direct Connect which is located in the US?

You are setting up some EBS volumes for a customer who has requested a setup which includes a RAID (redundant array of inexpensive disks). AWS has some recommendations for RAID setups. Which RAID setup is not recommended for Amazon EBS?
