ANSWERS

1.  a
Explanation:In cloud computing, you can often increase capacity on demand quickly and efficiently.

2.  d
Explanation:As much as possible, you also should assign servers standardized roles and populate those servers with identical services.

3.  a
Explanation:I/O Performance is high and API name is m2.4xlarge.

4.  b
Explanation:Small Instance has 1.7GB memory and 1 EC2 compute unit.

5.   a
Explanation:This variability may be due to your machine instances or storage buckets being moved from one system to another system.

6.   a
Explanation:This type of graph allows you to add the appropriate server type to your infrastructure while performing a cost analysis of the deployment.

7.  d
Explanation:High-CPU Extra Large Instance has 7GB of memory and 20 EC2 Compute Units.

8.  a
Explanation:We may add or substitute measures that go into the definition of an EC2 Compute Unit.

9.  b
Explanation:Not all cloud computing infrastructures automatically manage your capacity.

10.  b
Explanation:API name for small instance is m1.small.
