AWS Cloud Computing Fundamentals 4 — Questions and Answers
Question 1: Which AWS service provides a content delivery network (CDN) to distribute content with low latency?
- Amazon Route 53
- AWS Direct Connect
- Amazon CloudFront (Correct answer)
- Amazon VPC
Correct answer: Amazon CloudFront
Amazon CloudFront is AWS's CDN service that caches content at edge locations worldwide to reduce latency for end users.
Question 2: Under the AWS Shared Responsibility Model, which task is ALWAYS the customer's responsibility?
- Patching the hypervisor
- Managing physical data center security
- Controlling access to customer data and IAM configurations (Correct answer)
- Maintaining the global AWS network infrastructure
Correct answer: Controlling access to customer data and IAM configurations
Customers are always responsible for managing their data, configuring access controls, and managing IAM users, regardless of service type.
Question 3: What is the primary purpose of AWS Availability Zones?
- To reduce the cost of compute instances
- To provide fault isolation and enable high-availability architectures (Correct answer)
- To enforce data residency compliance
- To separate development and production environments
Correct answer: To provide fault isolation and enable high-availability architectures
Availability Zones are physically separate, isolated data centers within a Region that protect applications from single-datacenter failures.
Question 4: Which cloud service model provides the highest level of abstraction, allowing users to run applications without managing infrastructure or runtime environments?
- IaaS
- PaaS
- SaaS (Correct answer)
- FaaS
Correct answer: SaaS
SaaS (Software as a Service) delivers fully managed applications over the internet, requiring no infrastructure or platform management from the user.
Question 5: What is an AWS Edge Location used for?
- Running EC2 instances closer to on-premises data centers
- Caching content for CloudFront and serving Route 53 DNS queries (Correct answer)
- Hosting private VPN connections to AWS
- Providing dedicated hardware for compliance workloads
Correct answer: Caching content for CloudFront and serving Route 53 DNS queries
Edge Locations are AWS infrastructure points used by CloudFront to cache content and by Route 53 to answer DNS queries with low latency.
Question 6: Which benefit of cloud computing refers to the ability to access services from anywhere using a standard internet connection?
- Resource pooling
- Measured service
- Broad network access (Correct answer)
- Rapid elasticity
Correct answer: Broad network access
Broad network access means cloud services are available over the network and accessible through standard mechanisms from any location or device.
Question 7: A company wants to avoid the capital expense of purchasing servers. Which cloud computing advantage does this represent?
- Replacing variable expense with fixed expense
- Trading capital expense for variable expense (Correct answer)
- Eliminating the need for a network connection
- Providing unlimited free storage
Correct answer: Trading capital expense for variable expense
Cloud computing lets organizations trade large upfront capital expenditures (CapEx) for smaller, ongoing operational expenditures (OpEx) based on actual consumption.
