Practice Questions with Detailed Rationales (Version 2.0)
Domain 1: Cloud Concepts (24%) – Questions 1–36
Question 1
A multinational financial services company is evaluating the total cost of ownership (TCO) for
migrating their legacy data center to AWS. Which of the following represents an accurate
comparison between on-premises and cloud infrastructure costs?
, 2
A) On-premises costs are primarily variable while cloud costs are primarily fixed
B) AWS charges for idle capacity while on-premises does not
C) On-premises requires significant capital expenditure for hardware that may be underutilized
D) Cloud computing eliminates all operational expenses
-” detailed answer 100 % correct :-”C
Rationale: On-premises infrastructure requires significant capital expenditure (CAPEX) for
hardware that may be underutilized. The cloud transforms this to operational expenditure
(OPEX) where you pay only for resources consumed. Options A and B are incorrect because on-
premises has high fixed costs while cloud has variable costs. Option D is false because
operational expenses still exist but are shifted to the cloud provider.
Question 2
Which of the following correctly describes the relationship between the AWS Well-Architected
Framework and the AWS Cloud Adoption Framework (AWS CAF)?
A) They are identical frameworks with different names
B) The Well-Architected Framework focuses on architectural best practices while AWS CAF
focuses on organizational and process guidance for cloud adoption
C) AWS CAF replaces the Well-Architected Framework for new customers
D) Both frameworks only address security concerns
-” detailed answer 100 % correct :-”B
Rationale: The AWS Well-Architected Framework provides architectural best practices across six
pillars for building and operating workloads in the cloud. The AWS CAF provides guidance for
organizations on their cloud adoption journey, covering people, process, and technology
perspectives.
Question 3
A startup is developing a mobile application with unpredictable user adoption patterns. They
need to minimize infrastructure costs during initial development while having the ability to scale
rapidly. Which cloud value proposition is MOST relevant to their situation?
A) Go global in minutes
B) Trade capital expense for variable expense
, 3
C) Increase speed and agility
D) Stop guessing capacity
-” detailed answer 100 % correct :-”D
Rationale: "Stop guessing capacity" is most relevant because the startup cannot predict user
adoption. They can scale resources based on actual demand rather than forecasts, avoiding
over-provisioning costs while maintaining the ability to handle traffic spikes.
Question 4
An organization is planning a large-scale migration to AWS and wants to understand the
financial impact and create a business case. Which AWS resource provides a comprehensive
approach to cloud financial management?
A) AWS TCO Calculator
B) AWS Pricing Calculator
C) AWS Well-Architected Framework Cost Optimization pillar
D) AWS Cloud Financial Management (CFM) framework
-” detailed answer 100 % correct :-”D
Rationale: AWS Cloud Financial Management (CFM) provides a comprehensive approach to
planning, tracking, and optimizing cloud costs. While the TCO Calculator and Pricing Calculator
are useful tools, CFM encompasses the broader financial management strategy.
Question 5
Which of the following is a characteristic of the AWS global infrastructure that enables disaster
recovery across geographic locations?
A) Multiple Availability Zones within a single Region
B) Multiple AWS Regions with independent infrastructure
C) Edge Locations with content caching capabilities
D) Local Zones for low-latency applications
-” detailed answer 100 % correct :-”B
Rationale: Multiple AWS Regions enable disaster recovery across geographically separated
locations. If an entire Region experiences an outage, applications can failover to another Region.
, 4
While Availability Zones provide redundancy within a Region, Regions provide geographic
disaster recovery.
Question 6
A company wants to achieve the highest level of fault tolerance for their critical application.
Which AWS infrastructure component provides the best isolation from failures?
A) Edge Location
B) Availability Zone
C) Regional endpoint
D) Local Zone
-” detailed answer 100 % correct :-”B
Rationale: Availability Zones are designed for fault isolation. Each Availability Zone has
independent power, cooling, and networking. Deploying across multiple Availability Zones
protects against a single point of failure within a data center.
Question 7
According to the AWS Well-Architected Framework, which pillar focuses on the ability to
recover from infrastructure or service disruptions?
A) Operational Excellence
B) Security
C) Reliability
D) Performance Efficiency
-” detailed answer 100 % correct :-”C
Rationale: The Reliability pillar includes the ability to recover from infrastructure or service
disruptions. It encompasses the ability of a workload to perform its intended function correctly
and consistently when expected.
Question 8
Which of the following is an example of "increased speed and agility" as a cloud benefit?
