NEW QUESTION 3
A user is currently building a website which will require a large number of instances in six months, when a demonstration of the new site will be given upon launch.
Which of the below mentioned options allows the user to procure the resources beforehand so that they need not worry about infrastructure availability during the demonstration?

• A. Procure all the instances as reserved instances beforehand.
• B. Launch all the instances as part of the cluster group to ensure resource availability.
• C. Pre-warm all the instances one month prior to ensure resource availability.
• D. Ask AWS now to procure the dedicated instances in 6 month

Answer: A

Explanation: Amazon Web Services has massive hardware resources at its data centers, but they are finite. The best way for users to maximize their access to these resources is by reserving a portion of the computing capacity that they require. This can be done through reserved instances. With reserved instances, the user literally reserves the computing capacity in the Amazon Web Services cloud.

NEW QUESTION 4
You have set up an Auto Scaling group. The cool down period for the Auto Scaling group is 7 minutes. The first instance is launched after 3 minutes, while the second instance is launched after 4 minutes. How many minutes after the first instance is launched will Auto Scaling accept another scaling actMty request?

• A. 11 minutes
• B. 7 minutes
• C. 10 minutes
• D. 14 minutes

Answer: A

Explanation: If an Auto Scaling group is launching more than one instance, the cool down period for each instance starts after that instance is launched. The group remains locked until the last instance that was launched has completed its cool down period. In this case the cool down period for the first instance starts after 3 minutes and finishes at the 10th minute (3+7 cool down), while for the second instance it starts at the 4th minute and finishes at the 11th minute (4+7 cool down). Thus, the Auto Scaling group will receive another request only after 11 minutes.

NEW QUESTION 6
A user is running a batch process which runs for 1 hour every day. Which of the below mentioned options is the right instance type and costing model in this case if the user performs the same task for the whole year?

• A. EBS backed instance with on-demand instance pricing.
• B. EBS backed instance with heavy utilized reserved instance pricing.
• C. EBS backed instance with low utilized reserved instance pricing.
• D. Instance store backed instance with spot instance pricin

Answer: A

Explanation: For Amazon Web Services, the reserved instance helps the user save money if the user is going to run the same instance for a longer period. Generally if the user uses the instances around 30-40% annually it is recommended to use RI. Here as the instance runs only for 1 hour daily it is not recommended to have RI as it will be costlier. The user should use on-demand with EBS in this case.

• A. 12
• B. Unlimited
• C. 20
• D. 2

Answer: C

Explanation: Auto Scaling is an AWS service that allows you to increase or decrease the number of EC2 instances within your appIication's architecture. With Auto Scaling, you create collections of EC2 instances, called Auto Scaling groups. You can create these groups from scratch, or from existing EC2 instances that are already in production.
