CLOUD CONCEPTS & AWS GLOBAL INFRASTRUCTURE
(Questions 1–50)
Question 1 Which of the following is a benefit of cloud computing over
traditional on-premises infrastructure?
A. Pay-as-you-go pricing (no upfront capital expenditure) B. Unlimited
physical control over servers C. No need for security D. Fixed,
predictable capacity
Correct Answer: A Rationale: Cloud computing offers pay-as-you-go
(operational expenditure) instead of upfront hardware costs (capital
expenditure). Physical control (B) is less, not more. Security is still
required (C). Capacity is elastic, not fixed (D).

,Question 2 (Select all that apply) Which of the following are
characteristics of cloud computing according to the NIST definition?
(Select all that apply)
A. On-demand self-service B. Broad network access C. Resource
pooling D. Rapid elasticity E. Measured service
Correct Answers: A, B, C, D, E Rationale: These are the five essential
characteristics of cloud computing as defined by NIST.


Question 3 What is the term for the ability to scale computing resources
up or down automatically based on demand?
A. Elasticity B. Reliability C. Durability D. Latency
Correct Answer: A Rationale: Elasticity is the ability to scale resources
dynamically. Reliability (B) is the ability to recover from failures.
Durability (C) is data persistence. Latency (D) is delay.


Question 4 Which cloud deployment model is dedicated to a single
organization and may be hosted on-premises or by a third party?
A. Public cloud B. Private cloud C. Hybrid cloud D. Community cloud
Correct Answer: B Rationale: Private cloud is dedicated to one
organization. Public cloud (A) is shared. Hybrid cloud (C) combines
public and private. Community cloud (D) is shared among several
organizations with common concerns.


Question 5 (Select all that apply) Which of the following are advantages
of cloud computing? (Select all that apply)
A. Trade capital expense (CAPEX) for variable expense (OPEX) B.
Benefit from massive economies of scale C. Stop guessing capacity (scale

,as needed) D. Increase speed and agility (deploy in minutes) E. Go global
in minutes (deploy to multiple regions)
Correct Answers: A, B, C, D, E Rationale: All are key advantages of
cloud computing over on-premises infrastructure.


Question 6 What is the AWS global infrastructure component that
consists of one or more discrete data centers with redundant power,
networking, and cooling?
A. Availability Zone (AZ) B. Region C. Edge location D. Local Zone
Correct Answer: A Rationale: An Availability Zone is one or more
discrete data centers. A Region (B) is a cluster of Availability Zones.
Edge locations (C) are for CloudFront (content delivery).


Question 7 How many Availability Zones does an AWS Region typically
consist of?
A. 1 B. 2 or more (typically 3 or more) C. 10 or more D. Exactly 1
Correct Answer: B Rationale: Each AWS Region has at least 2
Availability Zones (most have 3 or more). Having multiple AZs enables
high availability and fault tolerance.


Question 8 What is the primary purpose of having multiple Availability
Zones within an AWS Region?
A. High availability and fault tolerance B. Lower latency C. Lower
cost D. Data sovereignty
Correct Answer: A Rationale: Multiple AZs allow you to run
applications across isolated locations so that if one AZ fails, another can
take over (high availability). Latency (B) is lower within a region, but
multiple AZs are for redundancy.

, Question 9 (Select all that apply) Which of the following are true about
AWS Regions? (Select all that apply)
A. A Region is a geographical area (e.g., US East, EU West) B. Resources
in different Regions are isolated by default C. Data does not leave a
Region unless you explicitly enable it D. All AWS services are available
in every Region E. You can choose which Region to deploy resources in
Correct Answers: A, B, C, E Rationale: Not all services are available in
all Regions (D). New services often launch in select Regions first.


Question 10 What is an AWS Edge Location?
A. A site used for content caching (CloudFront) and DNS (Route 53) B. A
data center within an Availability Zone C. A region with only one
Availability Zone D. A backup data center
Correct Answer: A Rationale: Edge locations are used by CloudFront
(CDN) and Route 53 (DNS) to deliver content with low latency. They are
not full data centers.


Question 11 Which AWS service uses Edge Locations to cache content
closer to users?
A. Amazon CloudFront B. Amazon S3 C. Amazon EC2 D. Amazon RDS
Correct Answer: A Rationale: CloudFront is AWS's content delivery
network (CDN) that caches content at edge locations. S3 (B) is storage;
EC2 (C) is compute; RDS (D) is database.


Question 12 What is a "Local Zone" in AWS?
