Correct (Verified Solutions)
1. A nurse informaticist is explaining the core concept of a cloud-based virtual server
that allows the hospital to rent computing capacity. Which AWS service is being
described?
A. Amazon S3
B. Amazon EC2
C. AWS Lambda
D. Amazon RDS
CORRECT ANSWER: B
Rationale: Amazon Elastic Compute Cloud (EC2) provides resizable, on-demand virtual
servers in the cloud, allowing organizations to rent computing capacity and pay only for
what they use.
2. When launching a virtual server for a new clinical application, which of the following
is a software blueprint that contains the operating system and application server?
D282
, 2
D282
A. Instance Type
B. Security Group
C. Amazon Machine Image (AMI)
D. Key Pair
CORRECT ANSWER: C
Rationale: An Amazon Machine Image (AMI) is a pre-configured software template that
provides the information required to launch an instance, including the operating system,
application server, and applications.
3. A team needs to select the hardware profile for a virtual server that will run a small
hospital database and web server. Which instance family is designed for general-
purpose use?
A. Compute optimized (c family)
B. Memory optimized (r family)
C. General purpose (t and m families)
D. Storage optimized (i family)
CORRECT ANSWER: C
Rationale: General purpose instance families (like t and m) provide a balance of
compute, memory, and networking resources, making them suitable for common
workloads like web servers and small databases.

4. Which component provides persistent, block-level storage that can be attached to a
virtual server, similar to a virtual hard drive?
A. Amazon S3
B. Elastic Block Store (EBS) Volume
C. Instance Store
D. Amazon EFS
CORRECT ANSWER: B
Rationale: An Amazon EBS volume is persistent, block-level storage designed for use
with EC2 instances. Data persists independently of the instance life, and volumes can be
detached and reattached.
5. A virtual firewall that controls inbound and outbound traffic for one or more virtual
servers is known as a:
A. Key Pair
B. Network ACL
C. Security Group
D. IAM Policy
CORRECT ANSWER: C
Rationale: A Security Group acts as a virtual firewall for associated EC2 instances,
controlling allowed inbound and outbound traffic at the instance level.

6. To securely connect to a Linux-based virtual server, a set of security credentials
consisting of a public and private key is required. This is known as a:
A. Security Group
B. Password
C. Key Pair
D. Access Key
CORRECT ANSWER: C
Rationale: A Key Pair (public and private key) is used for secure SSH authentication to
Linux-based EC2 instances, replacing traditional username/password access.
7. A core advantage of using on-demand cloud computing services like EC2 is that it
allows an organization to:
A. Increase capital expenses.
B. Stop guessing capacity needs.
C. Lengthen deployment timelines.
D. Reduce operational agility.
CORRECT ANSWER: B
Rationale: A primary cloud benefit is the ability to elastically scale resources up or down
based on actual demand, eliminating the need to provision for peak capacity guesses.
