Your development team is planning to host a development environment on the cloud. This consist of EC2 and RDS instances. This environment will probably only be required for 2 months. Which types of instances would you use for this purpose?

• On-Demand

• Spot

• Reserved

• Dedicated Hosts

An administrator would like to efficiently automate the replication and deployment of a specific software configuration existent on one EC2 instance onto four hundred others. Which AWS service is BEST suited for this implementation?

• AWS OpsWorks

• AWS Beanstalk

• AWS Launch Configuration

• AWS Auto-scaling

Amazon Elastic Compute Cloud (Amazon EC2) Spot Instances would be most appropriate for which of the following scenarios?

• Workloads that are only run in the morning and stopped in the night.

• Workloads where the availability of the Amazon EC2 instances can be flexible.

• Workloads that need to run for long periods of time without interruption.

• Workloads that are critical and need Amazon EC2 instances with termination protection.

Which AWS cloud service helps in quick deployment of resources which can make use of different programming languages such as .NET and Java?

• AWS Elastic Beanstalk

• AWS Elastic Compute Cloud (EC2)

• AWS VPC

• AWS SQS

A professional educational institution maintains a dedicated web server and database cluster that hosts an exam results portal for modules undertaken by its students. The resource is idle for most of the learning cycle and becomes excessively busy when exam results are released. How can this architecture be improved to be cost-efficient?

• Configure AWS Elastic Load-Balancing between the webserver and database cluster.

• Configure RDS multi-availability zone for performance optimization.

• Configure serverless architecture leveraging AWS Lambda Functions.

• Migrate the web servers onto Amazon EC2 Spot Instances.

You have a distributed application that periodically processes large volumes of data across multiple Amazon EC2 Instances. The application is designed to recover gracefully from Amazon EC2 instances failures. You required to accomplish this task in the most cost-effective way. Which of the following will meet requirements?

• Spot instances

• Reserved instances

• Dedicated instances

• On-demand instances

In Cost Optimization, what is referred to as EC2 Right Sizing?

• It is a cost-effective solution to determine the appropriate Amazon EC2 resources such as memory, processor type and storage when provisioning and instance type.

• It is a cost-saving solution that analyses data over a period of time to determine and recommend the type of Amazon EC2 instances appropriate for your workload.

• It is the scaling down or scaling up of Amazon EC2 instances and instances types to meet workload demand by maintaining onyle the threshold resources.

• It is a cost-saving solution that outlines the recommendations of best practice in four aspects namely cost optimization, performance, fault-tolerance and service limits.

Which of the following is a situation that would require using both Spot and Reserved EC2 instances?

• A build that has sudden unpredictable workload spikes but for a short time horizon.

• One in which there is a predictable resource demand over a long time horizon.

• One that has a predictable workload over a long time horizon with prolonged and unpredictable spikes.

• One that has a constantly predictable workload with brief unpredictable spikes.
