C02) EXAM BANK | COMPLETE EXAM
BANK WITH CORRECT ANSWERS AND
RATIONALES. A+ GRADED
1. Which of the following is a benefit of cloud
computing compared to on-premises infrastructure?
A) High upfront capital expenditure (CAPEX)
B) Pay-as-you-go pricing (variable expense instead of
upfront CAPEX)
C) Limited scalability
D) Physical access to servers is required for all
changes
Correct answer: B
Rationale: Cloud computing replaces upfront CAPEX
with variable operational expense (OPEX), allowing
pay-as-you-go and scaling without large initial
investments.
2. Which AWS service is used to provide a virtual
private network (VPN) connection between an on-
premises network and an AWS VPC?
A) AWS Direct Connect

responsibility for "Security OF the Cloud" to which
party?
A) The customer
B) AWS (the cloud provider)
C) A third-party auditor
D) The customer's security team

A) Amazon EC2 (Elastic Compute Cloud)
B) AWS Lambda
C) Amazon RDS
D) Amazon S3

with keys?
A) Amazon EBS (Elastic Block Store)
B) Amazon S3 (Simple Storage Service)
C) Amazon EFS (Elastic File System)
D) Amazon RDS
Correct answer: B
Rationale: S3 is object storage (buckets, keys,
objects). EBS is block storage for EC2. EFS is file
storage.
7. What is the primary purpose of an Amazon Machine
Image (AMI)?
A) To provide a template for launching EC2 instances
(OS, software, configuration)
B) To store snapshots of EBS volumes
C) To manage IAM permissions
D) To create load balancers
Correct answer: A
Rationale: An AMI contains the operating system,
applications, and launch settings needed to launch
EC2 instances. Custom AMIs can be created.
