Q2. A user wants to use an EBS-backed Amazon EC2 instance for a temporary job. Based on the input data, the job is most likely to finish within a week. Which of the following steps should be followed to terminate the instance automatically once the job is finished?
A. Configure the EC2 instance with a stop instance to terminate it.
B. Configure the EC2 instance with ELB to terminate the instance when it remains idle.
C. Configure the CIoudWatch alarm on the instance that should perform the termination action once the instance is idle.
D. Configure the Auto Scaling schedule actMty that terminates the instance after 7 days.
Answer: C
Explanation:
Auto Scaling can start and stop the instance at a pre-defined time. Here, the total running time is unknown. Thus, the user has to use the CIoudWatch alarm, which monitors the CPU utilization. The user can create an alarm that is triggered when the average CPU utilization percentage has been lower than 10 percent
for 24 hours, signaling that it is idle and no longer in use. When the utilization is below the threshold limit, it will terminate the instance as a part of the instance action.

Q6. You are running a news website in the eu-west-1 region that updates every 15 minutes. The website has a world-wide audience it uses an Auto Scaling group behind an Elastic Load Balancer and an
Amazon RDS database Static content resides on Amazon 53, and is distributed through Amazon CIoudFront. Your Auto Scaling group is set to trigger a scale up event at 60% CPU utilization, you use an Amazon RDS extra large DB instance with 10.000 Provisioned IOPS its CPU utilization is around 80%. While freeable memory is in the 2GB range.
Web analytics reports show that the average load time of your web pages is around 1 5 to 2 seconds, but your SEO consultant wants to bring down the average load time to under 0.5 seconds.
How would you improve page load times for your users? (Choose 3 answers)
A. Lower the scale up trigger of your Auto Scaling group to 30% so it scales more aggressively.
B. Add an Amazon EIastiCache caching layer to your application for storing sessions and frequent DB quenes
C. Configure Amazon CIoudFront dynamic content support to enable caching of re-usable content from your site
D. Switch Amazon RDS database to the high memory extra large Instance type
E. Set up a second installation in another region, and use the Amazon Route 53 latency-based routing feature to select the right region.
Answer: A, B, D
Q7. What does Amazon 53 stand for?
A. Simple Storage Solution.
B. Storage Storage Storage (triple redundancy Storage).
C. Storage Sewer Solution.
D. Simple Storage Sewice.
Answer: D
Q8. In the most recent company meeting, your CEO focused on the fact that everyone in the organization needs to make sure that all of the infrastructure that is built is truly scalable. Which of the following statements is incorrect in reference to scalable architecture?
A. A scalable service is capable of handling heterogeneity.
B. A scalable service is resilient.
C. A scalable architecture won't be cost effective as it grows.
D. Increasing resources results in a proportional increase in performance.
Answer: C
Explanation:
In AWS it is critical to build a scalable architecture in order to take advantage of a scalable infrastructure. The cloud is designed to provide conceptually infinite scalability. However, you cannot leverage all that scalability in infrastructure if your architecture is not scalable. Both have to work together. You will have to identify the monolithic components and bottlenecks in your architecture, identify the areas where you cannot leverage the on-demand provisioning capabilities in your architecture, and work to refactor your application, in order to leverage the scalable infrastructure and take advantage of the cloud.
Characteristics of a truly scalable application:
Increasing resources results in a proportional increase in performance A scalable service is capable of handling heterogeneity
A scalable service is operationally efficient A scalable service is resilient
A scalable service should become more cost effective when it grows (Cost per unit reduces as the number of units increases)

Q10. What does the following policy for Amazon EC2 do?
{
"Statement":[{
"Effect":"AI|ow", "Action":"ec2:Describe*", "Resource":"*"
II
}
A. Allow users to use actions that start with "Describe" over all the EC2 resources.
B. Share an AMI with a partner
C. Share an AMI within the account
D. Allow a group to only be able to describe, run, stop, start, and terminate instances
Answer: A
Explanation:
You can use IAM policies to control the actions that your users can perform against your EC2 resources. For instance, a policy with the following statement will allow users to perform actions whose name start with "Describe" against all your EC2 resources.
{
"Statement":[{
"Effect":"AI|ow", "Action":"ec2:Describe*", "Resource":"*"
}l
}

Q11. You need to create an Amazon Machine Image (AM) for a customer for an application which does not appear to be part of the standard AWS AM template that you can see in the AWS console. What are the alternative possibilities for creating an AM on AWS?
A. You can purchase an AMs from a third party but cannot create your own AM.
B. You can purchase an AMIs from a third party or can create your own AMI.
C. Only AWS can create AMIs and you need to wait till it becomes available.
D. Only AWS can create AMIs and you need to request them to create one for you.
Answer: B
Explanation:
You can purchase an AMIs from a third party, including AMIs that come with service contracts from organizations such as Red Hat. You can also create an AMI and sell it to other Amazon EC2 users. After you create an AMI, you can keep it private so that only you can use it, or you can share it with a specified list of AWS accounts. You can also make your custom AMI public so that the community can
use it. Building a safe, secure, usable AMI for public consumption is a fairly straightforward process, if you follow a few simple guidelines.
