Amazon (SAA-C03) Exam Questions And Answers page 16

How can a solutions architect analyze the performance of a web application with a granularity of 2 minutes in AWS?

Single Choice

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?

Create an AWS Lambda function to fetch EC2 logs from Amazon CloudWatch Logs. Use Amazon CloudWatch metrics to perform further analysis.

Send Amazon CloudWatch logs to Amazon Redshift. Use Amazon QuickSight to perform further analysis.

Enable detailed monitoring on all EC2 instances. Use Amazon CloudWatch metrics to perform further analysis.

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.

How can a solutions architect optimize website performance for a global audience on AWS?

Single Choice

A company hosts its product information webpages on AWS. The existing solution uses multiple Amazon C2 instances behind an Application Load Balancer in an Auto Scaling group. The website also uses a custom DNS name and communicates with HTTPS only using a dedicated SSL certificate. The company is planning a new product launch and wants to be sure that users from around the world have the best possible experience on the new website.

What should a solutions architect do to meet these requirements?

Redesign the application to use Amazon CloudFront.

Redesign the application to use AWS Elastic Beanstalk.

Redesign the application to use a Network Load Balancer.

Redesign the application to use Amazon S3 static website hosting.

Correct Answer:

Redesign the application to use Amazon CloudFront.

Explanation:

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.
If the content is already in the edge location with the lowest latency, CloudFront delivers it immediately.
If the content is not in that edge location, CloudFront retrieves it from an origin that you've defined such as an Amazon S3 bucket, a MediaPackage channel, or an HTTP server (for example, a web server) that you have identified as the source for the definitive version of your content.
As an example, suppose that you're serving an image from a traditional web server, not from CloudFront. For example, you might serve an image, sunsetphoto.png, using the URL http://example.com/sunsetphoto.png.
Your users can easily navigate to this URL and see the image. But they probably don't know that their request was routed from one network to another through the complex collection of interconnected networks that comprise the internet until the image was found.
CloudFront speeds up the distribution of your content by routing each user request through the AWS backbone network to the edge location that can best serve your content. Typically, this is a CloudFront edge server that provides the fastest delivery to the viewer. Using the AWS network dramatically reduces the number of networks that your users' requests must pass through, which improves performance. Users get lower latency the time it takes to load the first byte of the file and higher data transfer rates.
You also get increased reliability and availability because copies of your files (also known as objects) are now held (or cached) in multiple edge locations around the world.

How can a solutions architect increase availability for a company's static website hosted on Amazon S3 and distributed through CloudFront?

Multiple Choice

A company hosts its static website content from an Amazon S3 bucket in the us-east-1 Region. Content is made available through an Amazon CloudFront origin pointing to that bucket. Cross-Region replication is set to create a second copy of the bucket in the ap-southeast-1 Region. Management wants a solution that provides greater availability for the website.

Which combination of actions should a solutions architect take to increase availability? (Choose two.)

Add both buckets to the CloudFront origin.

Configure failover routing in Amazon Route 53.

Create a record in Amazon Route 53 pointing to the replica bucket.

Create an additional CloudFront origin pointing to the ap-southeast-1 bucket.

Set up a CloudFront origin group with the us-east-1 bucket as the primary and the ap-southeast-1 bucket as the secondary.

Which policy should be used to return the IP addresses of healthy EC2 instances in response to DNS queries on AWS?

Single Choice

A company hosts its web application on AWS using seven Amazon EC2 instances. The company requires that the IP addresses of all healthy EC2 instances be returned in response to DNS queries.

Which policy should be used to meet this requirement?

Simple routing policy

Latency routing policy

Multi-value routing policy

Geolocation routing policy

How can a solutions architect reduce costs for a company hosting its website on Amazon S3?

Single Choice

A company hosts its website on Amazon S3. The website serves petabytes of outbound traffic monthly, which accounts for most of the company's AWS costs. What should a solutions architect do to reduce costs?

Configure Amazon CloudFront with the existing website as the origin.

Move the website to Amazon EC2 with Amazon Elastic Block Store (Amazon EBS) volumes for storage.

Use AWS Global Accelerator and specify the existing website as the endpoint.

Rearchitect the website to run on a combination of Amazon API Gateway and AWS Lambda.

How can a solutions architect optimize costs and performance for a company's website hosted on AWS using Amazon EC2 Auto Scaling?

Single Choice

A company hosts its website on AWS. To address the highly variable demand, the company has implemented Amazon EC2 Auto Scaling. Management is concerned that the company is over-provisioning its infrastructure, especially at the front end of the three-tier application. A solutions architect needs to ensure costs are optimized without impacting performance.

What should the solutions architect do to accomplish this?

Use Auto Scaling with Reserved Instances.

Use Auto Scaling with a scheduled scaling policy.

Use Auto Scaling with the suspend-resume feature.

Use Auto Scaling with a target tracking scaling policy.

How can a solutions architect transmit and process 30 TB of clickstream data for a company with 300+ global websites?

Single Choice

A company hosts more than 300 global websites and applications. The company requires a platform to analyze more than 30 TB of clickstream data each day. What should a solutions architect do to transmit and process the clickstream data?

Design an AWS Data Pipeline to archive the data to an Amazon S3 bucket and run an Amazon EMR cluster with the data to generate analytics.

Create an Auto Scaling group of Amazon EC2 instances to process the data and send it to an Amazon S3 data lake for Amazon Redshift to use for analysis.

Cache the data to Amazon CloudFront. Store the data in an Amazon S3 bucket. When an object is added to the S3 bucket, run an AWS Lambda function to process the data for analysis.

Collect the data from Amazon Kinesis Data Streams. Use Amazon Kinesis Data firehose to transmit the data to an Amazon S3 data lake. Load the data in Amazon Redshift for analysis.
