Question 36

A company hosts its enterprise content management platform in one AWS Region but needs to operate the platform across multiple Regions The company has an Amazon Elastic Kubernetes Service (Amazon EKS) cluster that runs its microservices The EKS cluster stores and retrieves objects from Amazon S3 The EKS cluster also stores and retrieves metadata from Amazon DynamoDB
Which combination of steps should a solutions architect take to deploy the platform across multiple Regions? (Select TWO.)

A.Use Amazon API Gateway to create a global endpoint to the EKS cluster
B.Replicate the EKS cluster with cross-Region replication.
C.Deploy an EKS cluster and an S3 bucket in another Region Configure cross-Region replication on both S3 buckets Turn on global tables for DynamoDB
D.Use AWS Global Accelerator endpoints to distribute the traffic to multiple Regions
E.Use Amazon S3 access points to give access to the objects across multiple Regions Configure DynamoDB Accelerator (DAX) Connect DAX to the relevant tables.

Question 37

A solutions architect is designing a shared storage solution for a web application that is deployed across multiple Availability Zones. The web application runs on Amazon EC2 instances in an Auto Scaling group.
The company anticipates making frequent changes to the content, so the solution must have strong consistency Which solution meets these requirements?

A.Create an Amazon Elastic File System (Amazon EFS) file system and mount it on the individual EC2 instances.
B.Use AWS DataSync to perform continuous synchronization of data between EC2 hosts in the Auto Scaling group.
C.Create an Amazon S3 bucket to store the web content Use Amazon CloudFront to deliver the content.
D.Create a shared Amazon Elastic Block Store (Amazon EBS) volume and mount it on the individual EC2 instances.

Question 38

A company hosts its multi-tier public web application in the AWS Cloud. The web application runs on Amazon EC2 instances and its database runs on Amazon RDS The company is anticipating a large increase in sales during an upcoming holiday weekend A solutions architect needs to build a solution to analyze the performance of the web application with a granularity of no more than 2 minutes What should the solutions architect do to meet this requirement?

A.Enable detailed monitoring on all EC2 instances Use Amazon CloudWatch metrics to perform further analysis
B.Create an AWS Lambda function to fetch EC2 logs from Amazon CloudWatch Logs Use Amazon CloudWatch metrics to perform further analysis
C.Send Amazon CloudWatch logs to Amazon Redshift Use Amazon QuickSight to perform further analysis
D.Send EC2 logs to Amazon S3 Use Amazon Redshift to fetch logs from the S3 bucket to process raw data for further analysis with Amazon QuickSight.

Question 39

A company's website runs on Amazon EC2 instances behind an Application Load Balancer (ALB) The website has a mix of dynamic and static content Users around the globe are reporting that the website is slow Which set of actions will improve website performance for users worldwide?

A.Create an Amazon CloudFront distribution and configure the ALB as an origin Then update the Amazon Route 53 record to point to the CloudFront distribution
B.Create a latency-based Amazon Route 53 record for the ALB Then launch new EC2 instances with larger instance sizes and register the instances with the ALB
C.Launch nev. EC2 instances hosting the same web application in different Regions closer to the users. Then register the instances with the same ALB using cross-Region VPC peering
D.Host the website in an Amazon S3 bucket in the Regions closest to the users and delete the ALB and EC2 instances Then update an Amazon Route 53 record to point to the S3 buckets

Correct Answer: A

Reference:
What Is Amazon CloudFront?
Amazon CloudFront is a web service that speeds up distribution of your static and dynamic web content, such as .html, .css, .js, and image files, to your users. CloudFront delivers your content through a worldwide network of data centers called edge locations. When a user requests content that you're serving with CloudFront, the user is routed to the edge location that provides the lowest latency (time delay), so that content is delivered with the best possible performance.
Routing traffic to an Amazon CloudFront web distribution by using your domain name If you want to speed up delivery of your web content, you can use Amazon CloudFront, the AWS content delivery network (CDN). CloudFront can deliver your entire website-including dynamic, static, streaming, and interactive content-by using a global network of edge locations. Requests for your content are automatically routed to the edge location that gives your users the lowest latency.
To use CloudFront to distribute your content, you create a web distribution and specify settings such as the Amazon S3 bucket or HTTP server that you want CloudFront to get your content from, whether you want only selected users to have access to your content, and whether you want to require users to use HTTPS.
When you create a web distribution, CloudFront assigns a domain name to the distribution, such as d111111abcdef8.cloudfront.net. You can use this domain name in the URLs for your content, for example:
http://d111111abcdef8.cloudfront.net/logo.jpg
Alternatively, you might prefer to use your own domain name in URLs, for example:
http://example.com/logo.jpg
If you want to use your own domain name, use Amazon Route 53 to create an alias record that points to your CloudFront distribution. An alias record is a Route 53 extension to DNS. It's similar to a CNAME record, but you can create an alias record both for the root domain, such as example.com, and for subdomains, such as www.example.com. (You can create CNAME records only for subdomains.) When Route 53 receives a DNS query that matches the name and type of an alias record, Route 53 responds with the domain name that is associated with your distribution.

Question 40

A manufacturing company wants to implement predictive maintenance on its machinery equipment.
The company will install thousands of loT sensors that will send data to AWS in real time.
A solutions architect is tasked with implementing a solution that will receive events in an ordered manner for each machinery asset and ensure that data is saved for further processing at a later time.
Which solution would be MOST efficient?

A.Use Amazon Kinesis Data Streams for real-time events with a partition for each equipment asset.
Use Amazon Kinesis Data Firehose to save data to Amazon S3.
B.Use Amazon Kinesis Data Streams for real-time events with a shard for each equipment asset.
Use Amazon Kinesis Data Firehose to save data to Amazon EBS.
C.Use an Amazon SQS FIFO queue for real-time events with one queue for each equipment asset.
Trigger an AWS Lambda function for the SQS queue to save data to Amazon EFS.
D.Use an Amazon SQS standard queue for real-time events with one queue for each equipment asset.
Trigger an AWS Lambda function from the SQS queue to save data to Amazon S3.
