What will Auto Scaling do in this scenario?
A user has configured Auto Scaling with the minimum capacity as 2 and the desired capacity as 2. The user is trying to
terminate one of the existing instance with the command:
as-terminate-instance-in-auto-scaling-group<Instance ID>–decrement-desired-capacity

Your system recently experienced down time. During the troubleshooting process you found that
a new administrator mistakenly terminated several production EC2 instances.
Which of the following strategies will help prevent a similar situation in the future?
The administrator still must be able to:
– launch, start, stop, and terminate development resources,
– launch and start production instances.
What should the user do in this case?
A user is planning to scale up an application by 8 AM and scale down by 7 PM daily using Auto Scaling. What should the
user do in this case?

Refer to the architecture diagram above of a batch processing solution using Simple Queue
Service (SQS) to set up a message queue between EC2 instances which are used as batch
processors. CloudWatch monitors the number of job requests (queued messages) and an Auto
Scaling group adds or deletes batch servers automatically based on parameters set in
CloudWatch alarms.
You can use this architecture to implement which of the following features in a cost effective and
efficient manner?
which actions can he perform?
A root account owner has given full access of his S3 bucket to one of the IAM users using the bucket ACL. When the
IAM user logs in to the S3 console, which actions can he perform?
What DR strategy could be used to achieve this RTO and …
An ERP application is deployed across multiple AZs in a single region. In the event of failure, the
Recovery Time Objective (RTO) must be less than 3 hours, and the Recovery Point Objective
(RPO) must be 15 minutes. The customer realizes that data corruption occurred roughly 1.5
hours ago. What DR strategy could be used to achieve this RTO and RPO in the event of this
kind of failure?
Which of the below mentioned statements is true?
A user has created an Auto Scaling group with default configurations from CLI. The user wants to setup the CloudWatch
alarm on the EC2 instances, which are launched by the Auto Scaling group. The user has setup an alarm to monitor the
CPU utilization every minute. Which of the below mentioned statements is true?

Your application is using an ELB in front of an Auto Scaling group of web/application servers
deployed across two AZs and a Multi-AZ RDS Instance for data persistence. The database CPU
is often above 80% usage and 90% of I/O operations on the database are reads. To improve
performance you recently added a single-node Memcached ElastiCache Cluster to cache
frequent DB query results. In the next weeks the overall workload is expected to grow by 30%.
Do you need to change anything in the architecture to maintain the high availability of the
application with the anticipated additional load? Why?
How can the data be viewed better on the same graph?
A user is displaying the CPU utilization, and Network in and Network out CloudWatch metrics data of a single instance
on the same graph. The graph uses one Y-axis for CPU utilization and Network in and another Y-axis for Network out.
Since Network in is too high, the CPU utilization data is not visible clearly on graph to the user. How can the data be
viewed better on the same graph?
which architecture provides high availability?
Your company runs a customer facing event registration site. This site is built with a 3-tier
architecture with web and application tier servers and a MySQL database. The application
requires 6 web tier servers and 6 application tier servers for normal operation, but can run on a
minimum of 65% server capacity and a single MySQL database.
When deploying this application in a region with three availability zones (AZs), which architecture
provides high availability?
