You require the ability to analyze a customer’s clickstream data on a website, so they can do
behavioral analysis. Your customer needs to know what sequence of pages and ads their
customer clicked on. This data will be used in real time to modify the page layouts as customers
dick through the site, to increase stickiness and advertising click-through.
Which option meets the requirements for capturing and analyzing this data?

An AWS customer runs a public blogging website. The site users upload two million blog entries a
month. The average blog entry size is 200 KB. The access rate to blog entries drops to negligible
6 months after publication and users rarely access a blog entry 1 year after publication.
Additionally, blog entries have a high update rate during the first 3 months following publication,
this drops to no updates after 6 months. The customer wants to use CloudFront to improve his
user’s load times.
Which of the following recommendations would you make to the customer?

Your company is getting ready to do a major public announcement of a social media site on
AWS. The website is running on EC2 instances deployed across multiple Availability Zones with
an Multi-AZ RDS MySQL Extra Large DB Instance backend. The site performs a high number of
small reads and writes per second and relies on an eventual consistency model. After
comprehensive tests you discover that there is read contention on RDS MySQL.

A read only news reporting site with a combined web and application tier and a database tier that
receives large and unpredictable traffic demands must be able to respond to these traffic
fluctuations automatically. What AWS services should be used meet these requirements?

Your company has an on-premises, multi-tier PHP web application, which recently experienced
downtime due to a large burst in web traffic due to a company announcement. Over the coming
days, you’re expecting similar announcements to drive similar unpredictable bursts, and are
looking to find ways to quickly improve your infrastructures ability to handle unexpected increases
in traffic. The application currently consists of 2 tiers: A web tier, which consists of a load balancer
and several Linux Apache web servers, as well as a database tier, which hosts a Linux server
hosting a MySQL database.
Which scenario below will provide full site functionality, while helping to improve the availability of
your application in the short timeframe required?

Your team has a tomcat-based java application you need to deploy into development, test and
production environments. After some research, you opt to use Elastic Beanstalk due to its tight
integration with your developer tools and RDS due to its ease of management. Your QA team
lead points out that you need to roll a sanitized set of production data into your environment on a
nightly basis. Similarly, other software teams in your org want access to that same restored data
via their EC2 instances in your VPC. The optimal setup for persistence and security that meets
the above requirements would be the following:

A web-startup runs its very successful social news application on Amazon EC2 with an Elastic
Load Balancer, an Auto-Scaling group of Java/Tomcat application-servers, and DynamoDB as
data store. The main web-application best runs on m2.xlarge instances since it is highly memorybound. Each new deployment requires semi-automated creation and testing of a new AMI for the
application servers, which takes quite a while and is therefore only done once per week.
Recently, a new chat feature has been implemented in node.js and waits to be integrated in the
architecture. First tests show that the new component is CPU bound.
Because the company has some experience with using Chef, they decided to streamline the
deployment process and use AWS OpsWorks as an application life cycle tool to simplify
management of the application and reduce the deployment cycles.
What configuration in AWS OpsWorks is necessary to integrate the new chat module in the most
cost-efficient and flexible way?

Your customer is willing to consolidate their log streams (access logs, application logs, security
logs, etc.) in one single system. Once consolidated, the customer wants to analyze these logs in
real time based on heuristics. From time to time, the customer needs to validate heuristics, which
requires going back to data samples extracted from the last 12 hours.
What is the best approach to meet your customer’s requirements?

If I write the below command, what does it do?
ec2-run ami-e3a5408a -n 20 -g appserver

When you resize the Amazon RDS DB instance, Amazon RDS will perform the upgrade during
the next maintenance window. If you want the upgrade to be performed now, rather than waiting
for the maintenance window, specify the _____ option.
