Learn which AWS service requires customers to manage and update the guest operating system for the AWS Certified Cloud Practitioner CLF-C02 exam. Detailed explanation included.

Question

Which AWS service requires the customer to update the guest operating system?

A. AWS Lambda
B. Amazon OpenSearch Service
C. Amazon EC2
D. Amazon ElastiCache

Answer

C. Amazon EC2

Explanation

Customers are responsible for updating and patching the guest operating system on Amazon EC2 instances.

Amazon Elastic Compute Cloud (Amazon EC2) is the correct answer because it operates under the Infrastructure as a Service (IaaS) model. In this model, AWS provides the underlying hardware, virtualization, and networking, but customers are responsible for managing the guest operating system (OS), including updates, patches, and security configurations.

AWS follows a Shared Responsibility Model, which divides responsibilities between AWS and its customers:

AWS Responsibilities (“Security of the Cloud”)

AWS manages physical infrastructure, host operating systems, networking, and virtualization layers.

Customer Responsibilities (“Security in the Cloud”)

Customers are responsible for managing their EC2 instances, including:

  • Updating and patching the guest OS.
  • Installing and maintaining application software.
  • Configuring security groups and firewalls.

For Amazon EC2 instances, customers must ensure that their guest OS is updated regularly to maintain security and functionality. This includes applying patches for vulnerabilities and upgrading software as needed.

Why Not the Other Options?

  • AWS Lambda: As a serverless compute service, AWS Lambda abstracts infrastructure management. AWS handles all OS-level updates and patching for Lambda environments.
  • Amazon OpenSearch Service: This is a managed service where AWS takes care of underlying infrastructure and software updates. Customers only manage their data and configurations.
  • Amazon ElastiCache: While customers can control maintenance windows for updates, ElastiCache automatically applies updates to its managed infrastructure without requiring customer intervention.

Key Takeaways

  • Amazon EC2 requires customer management of the guest OS, aligning with its IaaS nature.
  • Understanding the shared responsibility model is crucial for identifying customer vs. AWS responsibilities in various services.
  • Services like Lambda, OpenSearch Service, and ElastiCache are managed by AWS, reducing operational overhead for customers.

By focusing on these distinctions, you’ll be well-prepared for questions on the CLF-C02 exam regarding service responsibilities!
