1. When you launch an Amazon Elastic Compute Cloud (Amazon EC2) in-
stance, what does the instance type define?: The amount of compute
for an Amazon EC2 instance, including RAM, instance storage, CPU,
and network bandwidth.
2. When you launch an Amazon Elastic Compute Cloud (Amazon EC2) in-
stance, what is defined by the Amazon Machine Image (AMI)?: The initial
software state of the instance when launched, including operating
system, con- figuration, and additional installed programs.
3. What is the drawback of Spot Instances?: They can be terminated
when the spot price goes above your current bid price.
4. How does the Amazon Elastic Compute Cloud (Amazon EC2)
ReservedIn- stance pricing model work? span&gt: ;You pay up front to
reserve compute for one or three years, locking in a lower cost in the
process.
5. What is the Amazon Elastic Compute Cloud (Amazon EC2) On Demand
pricing model?: You launch Amazon EC2 instances on request and pay
the full hourly cost until you stop or terminate the instances. This is
the most flexible and least cost-effective pricing model.
6. How can you address an Amazon Elastic Compute Cloud (Amazon EC2)
instance to connect over the Internet?: By public IP address, elastic IP
address, orDNS name. net?
7. What is Enhanced Networking for Amazon Elastic Compute Cloud
(Ama- zon EC2)?: A setting to get higher packet per second, lower
network jitter, and lower latencies.
8. What type of block storage is provided at no additional charge with
certain Amazon Elastic Compute Cloud (Amazon EC2) instance types?:
Instance Store (or ephemeral storage).

,9. VM Import/Export allows you to import existing virtual machines from
your local environmentand convert them to what?: Amazon Elastic
Compute Cloud (Amazon EC2) instances or Amazon Machine Images
(AMIs).
10.Which storage option continues to store data despite stopping and
start- ing an instance?: Amazon Elastic Block Store (Amazon EBS).
11.What does loosely coupled mean and why is it important?: Coupling is
the degree of direct knowledge that one component has of another.
Loose coupling is a design approach where components have very
little or no direct knowledge of each other. Loosely coupled systems
can scale to a greater extent than more tightly coupled systems.

, 12.What are the four network capacity ratings for Amazon Elastic
Compute Cloud (Amazon EC2) instance types?: Low, moderate, high,
and 10 Gbps.
13.What is instance metadata?: Data about an Amazon Elastic Compute
Cloud (Amazon EC2) instance—such as instance ID, instance
type, and security groups—that can be obtained via an HTTP
call from within the instance.
14.What are the four properties of a security group rule?: Traffic
direction, port, protocol, and destination (or source) address.
15.When an Amazon Elastic Compute Cloud (Amazon EC2) instance is a
member of two security groups, what resulting traffic flow is allowed?:
The rules from each security group are aggregated to create one set
of permissive rules, so the result is a union of all traffic allowed by the
rules in both security groups.
16.Which Amazon Elastic Block Storage (Amazon EBS) volume type is the
best choice for workloads such as large databases executing many
transac- tions?: Provisioned IOPS SSD.
17.What Amazon Elastic Block Storage (Amazon EBS) volume type is
appro- priate for cold and infrequently accessed data?: Magnetic
volumes.
18.Which Amazon Elastic Block Storage (Amazon EBS) volume type is
appropriate for dev/test environments, small databases, and so forth?:
Gen- eral-purpose SSD.
19.What must an application running on an Amazon Elastic Compute
Cloud (Amazon EC2) instance do differently to access data on an
encrypted Ama- zon Elastic Block Storage (Amazon EBS) volume?:
Nothing. Amazon EBS encryption is transparent to applications on the
attached instances.
20.What is an Amazon Elastic Block Storage (Amazon EBS)-optimized in-
stance?: An instance that has additional, dedicated capacity for
Amazon EBS I/O.
21.What are Amazon Elastic Block Storage (Amazon EBS) snapshots?: -
Point-in-time backups of an Amazon EBS volume stored in Amazon
Simple Stor- age Service (Amazon S3). lastic Block Storage (Amazon
EBS) volume?
