NEW QUESTION 1
A user is planning to use AWS Cloudformation. Which of the below mentioned functionalities does not help him to correctly understand Cloudfromation?

• A. Cloudformation follows the DevOps model for the creation of Dev & Test
• B. AWS Cloudfromation does not charge the user for its service but only charges for the AWS resources created with it
• C. Cloudformation works with a wide variety of AWS services, such as EC2, EBS, VPC, IAM, S3, RDS, ELB, etc
• D. CloudFormation provides a set of application bootstrapping scripts which enables the user to install Software

Answer: A

Explanation:
AWS Cloudformation is an application management tool which provides application modelling, deployment, configuration, management and related activities. It supports a wide variety of AWS services, such as EC2, EBS, AS, ELB, RDS, VPC, etc. It also provides application bootstrapping scripts which enable the user to install software packages or create folders. It is free of the cost and only charges the user for the services created with it. The only challenge is that it does not follow any model, such as DevOps; instead customers can define templates and use them to provision and manage the AWS resources in an orderly way.

A user is trying to create a PIOPS EBS volume with 4000 IOPS and 100 GB size. AWS does not allow the user to create this volume. What is the possible root cause for this?

• A. The ratio between IOPS and the EBS volume is higher than 30
• B. The maximum IOPS supported by EBS is 3000
• C. The ratio between IOPS and the EBS volume is lower than 50
• D. PIOPS is supported for EBS higher than 500 GB size

Answer: A

Explanation:
A provisioned IOPS EBS volume can range in size from 10 GB to 1 TB and the user can provision up to 4000 IOPS per volume. The ratio of IOPS provisioned to the volume size requested should be a maximum of 30; for example, a volume with 3000 IOPS must be at least 100 GB.

NEW QUESTION 4
A user is having data generated randomly based on a certain event. The user wants to upload that data to CloudWatch. It may happen that event may not have data generated for some period due to andomness. Which of the below mentioned options is a recommended option for this case?

• A. For the period when there is no data, the user should not send the data at all
• B. For the period when there is no data the user should send a blank value
• C. For the period when there is no data the user should send the value as 0
• D. The user must upload the data to CloudWatch as having no data for some period will cause an error at CloudWatch monitoring

Answer: C

Explanation:
AWS CloudWatch supports the custom metrics. The user can always capture the custom data and upload the data to CloudWatch using CLI or APIs. When the user data is more random and not generated at regular intervals, there can be a period which has no associated data. The user can either publish the zero (0. Value for that period or not publish the data at all. It is recommended that the user should publish zero instead of no value to monitor the health of the application. This is helpful in an alarm as well as in the generation of the sample data count.

NEW QUESTION 5
A user had aggregated the CloudWatch metric data on the AMI ID. The user observed some abnormal
behaviour of the CPU utilization metric while viewing the last 2 weeks of data. The user wants to share that data with his manager. How can the user achieve this easily with the AWS console?

• A. The user can use the copy URL functionality of CloudWatch to share the exact details
• B. The user can use the export data option from the CloudWatch console to export the current data point
• C. The user has to find the period and data and provide all the aggregation information to the manager
• D. The user can use the CloudWatch data copy functionality to copy the current data points

Answer: A

Explanation:
Amazon CloudWatch provides the functionality to graph the metric data generated either by the AWS services or the custom metric to make it easier for the user to analyse. The console provides the option to save the URL or bookmark it so that it can be used in the future by typing the same URL. The Copy URL functionality is available under the console when the user selects any metric to view.

A user has created a queue named “myqueue” in US-East region with AWS SQS. The user’s AWS account ID is 123456789012. If the user wants to perform some action on this queue, which of the below Queue URL should he use?

• A. http://sqs.us-east-1.amazonaws.com/123456789012/myqueue
• B. http://sqs.amazonaws.com/123456789012/myqueue
• C. http://sq
• D. 123456789012.us-east-1.amazonaws.com/myqueue
• E. http:// 123456789012.sq
• F. us-east-1.amazonaws.com/myqueue

Answer: A

Explanation:
When creating a new queue in SQS, the user must provide a queue name that is unique within the scope of all queues of user’s account. If the user creates queues using both the latest WSDL and a previous version, he will have a single namespace for all his queues. Amazon SQS assigns each queue created by user an identifier called a queue URL, which includes the queue name and other components that Amazon SQS determines. Whenever the user wants to perform an action on a queue, he must provide its queue URL. The queue URL for the account id 123456789012 & queue name “myqueue” in US-East-1 region will be http:// sqs.us-east-1.amazonaws.com/123456789012/myqueue.

NEW QUESTION 15
A user has launched an EC2 instance and deployed a production application in it. The user wants to prohibit any mistakes from the production team to avoid accidental termination.
How can the user achieve this?

• A. The user can the set DisableApiTermination attribute to avoid accidental termination
• B. It is not possible to avoid accidental termination
• C. The user can set the Deletion termination flag to avoid accidental termination
• D. The user can set the InstanceInitiatedShutdownBehavior flag to avoid accidental termination

Answer: A

Explanation:
It is always possible that someone can terminate an EC2 instance using the Amazon EC2 console, command line interface or API by mistake. If the admin wants to prevent the instance from being accidentally terminated, he can enable termination protection for that instance. The DisableApiTermination attribute controls whether the instance can be terminated using the console, CLI or API. By default, termination protection is disabled for an EC2 instance. When it is set it will not allow the user to terminate the instance from CLI, API or the console.

NEW QUESTION 16
A user has configured ELB with two EBS backed instances. The user has stopped the instances for 1 week to save costs. The user restarts the instances after 1 week. Which of the below mentioned statements will help the user to understand the ELB and instance registration better?

• A. There is no way to register the stopped instances with ELB
• B. The user cannot stop the instances if they are registered with ELB
• C. If the instances have the same Elastic IP assigned after reboot they will be registered with ELB
• D. The instances will automatically get registered with ELB

Answer: C

Explanation:
Elastic Load Balancing registers the user’s load balancer with his EC2 instance using the associated IP address. When the instances are stopped and started back they will have a different IP address. Thus, they will not get registered with ELB unless the user manually registers them. If the instances are assigned the same Elastic IP after reboot they will automatically get registered with ELB.
