zone and place the ELB in front of that.

4. Place all 9 EC2 instances in single Availability Zone and 1 in another Availability Zone in any region and place the ELB in front of that.

Explanation: What is ELB ?
Elastic Load Balancing automatically distributes incoming application traffic across multiple Amazon EC2 instances. It enables you to achieve fault
tolerance in your applications, seamlessly providing the required amount of load balancing capacity needed to route application traffic.

Achieve higher levels of fault tolerance for your applications by using Elastic Load Balancing to automatically route traffic across multiple instances
and multiple Availability Zones. Elastic Load Balancing ensures that only healthy Amazon EC2 instances receive traffic by detecting unhealthy instances and
rerouting traffic across the remaining healthy instances. If all of your EC2 instances in one Availability Zone are unhealthy, and you have set up EC2
instances in multiple Availability Zones, Elastic Load Balancing will route traffic to your healthy EC2 instances in those other zones.

ELB Restrictions:

1. You can use ELB only across the Availability Zone in the same region only. ELB can not be configured for across region.
Hence, best suitable answer is 3

4. Amazon DynamoDB

Ans : 2

Exp : As Amazon's business grew from being a startup in
the mid-1990s to a global multi-billion-dollar business, we came to realize the scaling limitations of relational databases. A number of high profile
outages at the height of the 2004 holiday shopping season can be traced back to scaling relational database technologies beyond their capabilities. In
response, we began to develop a collection of storage and database technologies to address the demanding scalability and reliability requirements of the
Amazon.com ecommerce platform. This was the genesis of NoSQL databases like Dynamo at Amazon. From our own experience designing and operating a highly
available, highly scalable ecommerce platform, we have come to realize that relational databases should only be used when an application really needs the
complex query, table join and transaction capabilities of a full-blown relational database. In all other cases, when such relational features are not
needed, a NoSQL database service like DynamoDB offers a simpler, more available, more scalable and ultimately a lower cost solution.




Question : You have deployed HadoopExam.com website on AWS and using the EC instances and DynamoDB as a database. As you know, all the applications
deployed on Amazon EC2 is very critical for your business. Hence, you want basic monitoring and if required you also want to look in detail matrices.
Which of the best service AWS provides to monitor EC2 instances and DynamoDB

4. Each component has its own monitoring tool. Which you can configure in AWS dashboard, to see on single screen. Also you can watch each components detail view.


Correct Answer : Get Lastest Questions and Answer :
Explanation: Amazon CloudWatch is a monitoring service for AWS cloud resources and the applications you run on AWS. You can use Amazon
CloudWatch to collect and track metrics, collect and monitor log files, and set alarms. Amazon CloudWatch can monitor AWS resources such as Amazon EC2 instances,
Amazon DynamoDB tables, and Amazon RDS DB instances, as well as custom metrics generated by your applications and services, and any log files your applications
generate. You can use Amazon CloudWatch to gain system-wide visibility into resource utilization, application performance, and operational health. You
can use these insights to react and keep your application running smoothly.

Monitor Amazon EC2 : View metrics for CPU utilization, data transfer, and disk usage activity from Amazon EC2 instances (Basic Monitoring) for no additional charge. For an
additional charge, CloudWatch provides Detailed Monitoring for EC2 instances with higher resolution and metric aggregation. No additional
software needs to be installed. Hence, you can use Cloudwatch for Basic as well as Detailed Monitoring.
