End of Course Assessment :AWS Cloud Technical Essentials (AWS Fundamentals Specialization) Answers 2025

Question 1

How do we choose an AWS Region?

✅ Latency, price, service availability, and compliance
❌ Latency, high availability, taxes, and compliance
❌ Latency, taxes, speed, and compliance
❌ Latency, security, high availability, and resiliency

Explanation:
When selecting an AWS Region, architects consider latency, pricing, service availability, and compliance requirements to balance performance, cost, and regulations.

Question 2

Relationship between Regions, Availability Zones, and data centers:

✅ Regions are clusters of Availability Zones. Availability Zones are clusters of data centers.
❌ Availability Zones are clusters of Regions
❌ Data centers are clusters of AZs
❌ Data centers are clusters of Regions

Explanation:
The AWS Global Infrastructure hierarchy:
Regions → Availability Zones → Data Centers.
Each Region has multiple AZs, and each AZ contains one or more physical data centers.

Question 3

What can be found in an AWS IAM policy?

✅ A and B (Effect and Action)
❌ Object
❌ B and C

Explanation:
An IAM policy statement includes:

• Effect (Allow or Deny)

• Action (specific API operations)

• Resource (what it applies to)

Question 4

Which AWS identity allows users to access AWS via corporate sign-in without separate credentials?

✅ IAM Role
❌ Root user
❌ IAM user
❌ IAM group

Explanation:
IAM Roles are used for federated access (e.g., single sign-on from corporate systems) so users don’t need AWS-specific credentials.

Question 5

How can a company allow public subnet resources to access the internet?

✅ B and C (Attach an internet gateway + Create route to the IGW)
❌ Only attach IGW
❌ Only route creation
❌ A and B

Explanation:
To enable internet access, you must:

1. Attach an Internet Gateway (IGW) to the VPC.

2. Create a route from the public subnet to the IGW.

Question 6

What does an Amazon EC2 instance type indicate?

✅ Instance family and instance size
❌ Placement and size
❌ Tenancy and billing
❌ AMI and speed

Explanation:
Each EC2 instance type defines a family (use case: compute, memory, storage) and a size (resource allocation within the family).

Question 7

Typical use case for Amazon S3:

✅ Object storage for media hosting
❌ Object storage for boot drive
❌ Block storage for EC2
❌ File storage for multiple EC2s

Explanation:
Amazon S3 provides object storage for scalable data like images, videos, backups, and analytics datasets.

Question 8

Which S3 tier is ideal for long-term, rarely accessed data (like patient records)?

✅ Amazon S3 Glacier Deep Archive
❌ S3 Standard
❌ S3 Standard-IA
❌ S3 Intelligent-Tiering

Explanation:
S3 Glacier Deep Archive is the lowest-cost storage option for data retained for years and rarely retrieved.

Question 9

What are users responsible for in Amazon RDS?

✅ Optimizing the database
❌ Managing infrastructure
❌ Installing DB software
❌ OS patching

Explanation:
RDS is fully managed—AWS handles infrastructure, backups, and patching. Users still handle schema design, performance tuning, and IAM/network access.

Question 10

True or False: Multi-AZ increases database availability.

✅ True
❌ False

Explanation:
A Multi-AZ deployment automatically replicates data to another Availability Zone, providing high availability and automatic failover.

Question 11

What are the three components of EC2 Auto Scaling?

✅ Launch template, scaling policies, EC2 Auto Scaling group
❌ Scaling policies, security group, ASG
❌ Security group, instance type, key pair
❌ AMI, instance type, storage

Explanation:
Auto Scaling needs:

1. Launch template/configuration

2. Scaling policies

3. Auto Scaling group (ASG)

Question 12

Which load balancer type chooses target groups by URL path rules?

✅ Application Load Balancer (ALB)
❌ Classic Load Balancer
❌ Network Load Balancer

Explanation:
Application Load Balancer (ALB) operates at Layer 7 (HTTP/HTTPS) and supports path-based routing, unlike NLB (Layer 4).
